Damage to your roof from weather, aging, or other causes can cause problems that go beyond aesthetics. Heat loss is one of the main issues since it has a big effect on the comfort and energy efficiency of your house. During the colder months, a broken roof lets warm air escape, making your heating system work harder and increasing your energy costs.
It is imperative to promptly attend to a damaged roof in order to preserve a cozy interior atmosphere. Good insulation keeps heat in and keeps cold drafts out, improving the coziness and energy efficiency of your living areas. Your home’s overall thermal performance can be improved by fixing and properly insulating your damaged roof.
Selecting appropriate insulation materials and techniques is essential for efficiently warming a damaged roof. The roof structure can be insulated using materials like fiberglass, spray foam, or rigid foam boards, based on your needs and financial constraints. For long-term energy savings and maximum effectiveness, proper installation is necessary.
By lowering the carbon footprint of your house, making sure your roof is adequately insulated not only increases energy efficiency but also promotes environmental sustainability. Homeowners can create a more cosy and eco-friendly living space by improving insulation and fixing roof damage.

How to make insulation of the attic roof – the choice of material and the method of thermal insulation of the structure
In order to guarantee a year-long comfortable stay in the attic, the home’s owners must buy high-quality insulation and install it with careful consideration for all the details. Only if the attic roof’s thermal insulation is done correctly will the roofing pie last a long time.
Features of the insulation of the attic roof
A microclimate that is conducive to human habitation is created in the premises if the insulation arrangement technology is followed. It will be cozy and warm on chilly days, and because thermal insulation is there, the air won’t overheat on hot days.
It won’t hurt the homeowner to buy high-quality tools and building supplies and learn about the characteristics of the roof pie arrangement before insulating the attic roof.
While there are certain restrictions, the process of thermally insulating attic structures on private homes is largely similar to that of insulating roofs of other species. This is because the walls of these rooms are either formed by the structure’s gables and roof slopes, or they are closely next to the slopes. Because of this, the air in the attic overheats on hot days and rapidly cools on cold ones.
When viewed from the inside layer toward the outside, the attic roof’s structure looks like this:
- vapor barrier;
- insulation;
- ventilation gap;
- waterproofing;
- finish.
According to the attic roof insulation technology, each of the aforementioned layers is required because they each serve a distinct purpose.
How to insulate the roof of the attic correctly
Since the arrangement of ventilation and thermal insulation determines how comfortable the attic floor will be, more attention needs to be paid to these factors. Thermal conductivity, or the capacity to direct heat into a room and the other way around, is taken into consideration when selecting insulation.
The material’s ability to shield the attic from heat energy loss is indicated by how low this indicator goes. This implies that it will be feasible to install a lower layer of insulation in order to guarantee the required degree of thermal insulation of the roof.
Because heated air always rises, the roof of a heated room loses the most heat. It moves in the direction of the coating, where the snow layer is found in the winter, and passes through the layers of a roofing cake.
Because of its porous structure and internal air pockets, snow acts as an external heat insulator at air temperatures below 2 degrees Celsius.
The coating material heats up significantly and the snow layers start to melt if there is a significant amount of heat loss from the roof. The resultant water then turns into ice when the temperature drops. The roof’s surface is greatly endangered by the presence of frozen crust, as the weight on the rafter structure is greatly increased. When the attic roof is properly insulated from the inside, snow does not start to build up on it during chilly weather.
Excess heat from the roof enters the attic during the summer, making it impossible to keep the room at a comfortable temperature without the assistance of the air conditioner. By installing a high-quality layer of thermal insulation from the inside of the roof, you can prevent such an issue. It goes without saying that the attic floor will always be warmer than the lower levels of the buildings, but this will not be an uncomfortable situation.
The attic for the attilation of the attic
The features of the attic’s design explain why roofing above it requires a unique approach. The standard roof receives ventilation because there is an attic with sound-absorbing windows. The attic has a ventilation space of only ten to fifteen centimeters.
It’s crucial to properly create a ventilation gap when setting up a roof like this for a roof pie installation. This gap between the insulation and waterproofing layers should help drain excess moisture and keep the roof from overheating in the winter due to the formation of an ice crust.
The ventilation arrangement will provide protection to the entire structure, extending the roof elements’ operational lifespan. Heat is partially allocated on hot days because of a gap from under the roof; this prevents the air in the attic from becoming too hot.
The choice of thermal insulation material
Selecting high-quality materials is necessary prior to insulating the attic with a broken roof and installing a roofing pie. Its technical parameters determine the thickness of the future isolation and the number of layers of insulation. The home building material market offers an enormous assortment of products for roofing construction.
The most well-liked ones among them are:
- mineral wool;
- extruded polystyrene foam;
- glass wool;
- Poliuretan foam.
The use of foamed glass is permitted in certain situations. Natural materials are used for internal insulation, including wood chips and seaweed.
Priority in the choice
A number of technical factors are considered when selecting a heat insulator:
- coefficient of thermal conductivity;
- environmental friendliness;
- fire resistance;
- moisture resistance.
Experts believe that installing insulation with a thermal conductivity coefficient of 0.05 watts per square meter or less is the best option for installing an attic roof.
The longer insulation lasts without losing its functional qualities, the higher the insulation’s moisture resistance indicator. The material’s environmental friendliness is a crucial factor. Housing’s ability to withstand fire is crucial to its fire safety.
Melting rocks are used to create insulation such as mineral wool. It does not rot, retains heat perfectly, is resistant to temperature fluctuations and harsh environments, and only slightly absorbs moisture. This material’s mats come in a variety of thicknesses, making them practical for use in the arrangement of the attic roof’s thermal insulation.
Glass wools are made from molten glass. This kind of insulation is similar to mineral wool in many aspects, but its temperature threshold is lower than -450 °C. It’s a good heat- and sound-insulator. However, as moisture can gather in between its fibers, proper installation techniques are required.
The cost of using glass wool and mineral wool for insulation is low, and using them will save money. However, using them calls for installing a substantial layer of thermal insulation as well as a dependable vapor and hydro-barrier device.
Moreover, polymeric materials are utilized to warm the roof structure internally. For instance, polyurethane foam has several benefits, including low weight, high heat conservation, and durability. He is impervious to moisture and does not pass steam. Also see "How to insulate the attic roof-the selection of materials and insulation guidelines."
Without taking off the roof, polistyle foam can insulate the attic quite well. Its thermal conductivity coefficient is 0.05 W/m³K. The substance in question is hydrophobic and does not pass steam. Polistyle foam is classified as G1–G4 combustibility. Polymer heaters, incidentally, are pricey synthetic materials. As a result, they are not utilized when building a home using only eco-friendly materials.
It should be highlighted that although natural heaters have advantages, such as good thermal conductivity, they also have drawbacks. Foamed glass, for instance, is extremely delicate, and materials like granular paper and straw-and-reed mats vary greatly in grief. You must possess the necessary knowledge and abilities and understand how the attic roof is insulated using natural heat insulators.
The technology of laying thermal insulation
You must follow the detailed instructions for carrying out construction work if you want to install insulation of the highest caliber during the installation of a roof pie.
There are various steps involved in insulating a house’s roof, including:
- preparation for laying insulation;
- installation of thermal insulation;
- Material fastening.
The following are the steps involved in arranging insulation:
- During the development of the project of the construction of the rafter structure, you need to decide on the step of the installation of the rafters. At the same time, one should not forget that it should turn out to be strong and reliable, and the gap between the rafter legs cannot exceed standard values. In the case when the heat -insulating material is already chosen, the rafters are mounted so that the heater slabs are placed between them tightly. Such a technology greatly simplifies installation and minimizes the number of waste of building materials.
- A layer of waterproofing is mounted between the rafters and the crate over thermal insulation. Its canvases are laid on, starting work from the lower edge of the slope. Each subsequent row should overlap the previous layer by 15 centimeters. The film is fixed on the tree with a construction stapler. Then the counterracies are attached, the thickness of which provides a ventilation gap of sufficient size. The rails are fixed on the rafters with self -tapping screws, although it is possible.
- From the inside of a fully prepared rafter structure, the insulation is laid and reliably fixed.
The nuances of insulation of the broken roof
Because the metal or wood rafter legs have a lower thermal conductivity coefficient than the heat-insulating materials that are used, these bridges are known as cold bridges. Because of this, when setting up the attic, the insulation must be mounted in places other than between the rafters. The aforementioned mats must have a continuous layer of thermal insulation applied on top of them; however, in this instance, a thinner material is used.
The technology mentioned above aids in raising insulation quality. However, there are drawbacks to this method, such as the fact that the rafters will eventually be completely closed and that it will be challenging to use to fix other roof structure components. Noting the rafters’ locations is essential to guaranteeing more installation work.
The thermal insulation layer is covered with a vapor-permeable film that serves to absorb excess moisture. The crate is then fastened. The internal sheathing of the ceiling surface is completed as the last phase of thermal insulation work.
If the instructions for insulating the attic’s broken roof are followed precisely, a favorable microclimate will be created that will allow you to use the living area all year long.
Attic roof self-insulation is completely possible, but only if the specifications for this kind of roofing work are met.
How to dress an attic roof, a thermal insulation device, and attic insulation technology for a roof that is broken
How to dress an attic roof, a thermal insulation device, and attic insulation technology for a roof that is broken
Our article on "All about the roof" delves into the important topic of fixing a damaged roof in order to enhance insulation. Damage to the roof impairs the house’s capacity to retain heat effectively, resulting in higher energy expenses and discomfort. This article will walk homeowners through the process of locating and fixing roof damage, stressing the significance of using the right materials and methods for insulation. By tackling these problems, readers will discover workable ways to improve the comfort and energy efficiency of their homes and increase the roof’s lifespan.
The insulation of the attic roof
In addition to the insulation, the air in the undercarbon space provides effective thermal insulation if the attic is left empty. Everything is entirely incorrect in the case of the attic, where thermal insulation is used in close proximity to roofing materials in order to create conditions that not only adequately insulate the attic but also extend the lifespan of the roofing system as a whole.
Certain regulations must be followed when insulating the browned roof of the attic type.
We will immediately say that all the wood that is used in the construction of the roof should be processed by antiseptics. Indeed all: both crate and counter-ribbons and rafters. All wooden details. It is also necessary to make them less combustible. For this they are treated with antipyrens. All the elements that are located from the street are processed for external work. All wooden details facing the room, process impregnations for internal work. If the premises are used for external work, a specific smell will remain for several years. If, on the contrary, wood can suffer from the outside: the degree of protection is insufficient. Because in this case do not save.
Extra. It’s important to remember this before we go over how to manually insulate the attic roof: the undercarbon space needs to have a ventilation system set up. On the skate, specific ventilation holes have been placed for this purpose. Air from beneath the roofing material escapes through them, carrying with it too much humidity. And he has to tumble through overhangs beneath the roof’s flooring. You simply cannot accomplish everything there. From there, there is an air fence. Condensate can only dry quickly in this manner, ensuring a long lifespan for the roof.
Moving the air masses under roofing material is necessary to ensure proper insulation and timely removal of moisture.
Proper insulation of the attic
It is vital to properly insulate the roof in order for the attic floor to remain warm in the winter and cool in the summer, high humidity issues to be resolved, and icicles to not form on the roof. However, when it comes to the roof, waterproofing, insulation, and steam work together as a complete solution; one of these alone either performs poorly or not at all.
If the attic floor’s walls and the broken roof are both present at the same time, the pie will look like this (from the inside, that is):
- internal sheathing (drywall or lining);
- crate;
- vapor barrier;
- insulation (the thickness of the insulation depends on the region and the parameters of the insulation, for the middle band of Russia it is about 200 mm);
- superdiffusion membrane;
- venturezor;
- crate;
- Roofing.
How to insulate an attic roof: a breakdown of a residential roof in layers
The graphic version of the picture displays insulation on a damaged attic roof. Note that the insulation is covered with a superdiffusion membrane (shown in blue). Its goal is to stop condensation or precipitation from seeping through the roofing and to extract the pairs that still reach the minvata, guaranteeing its drying. In light of this, vapor permeability starts at 1500 g/m 2. Although it is only vapor-permeable, this layer is frequently referred to as waterproofing.
It should fit precisely as the figure illustrates, encircling the rafters and snugly fitting on the insulation. It is frequently rolled out on top of the rafters for savings, sagging 3-5 cm instead of pulling. This alternative also functions effectively: moisture rises to the surface, rolls down, and is eliminated outside the roof. Another crucial point to remember is that the membrane needs to reach the water border groove. The under-circuit area will then have moisture removed from it.
This is how waterproofing can be laid: slightly sagging but definitely not pulling
A few more remarks regarding membrane laying. It begins below and rolls across the rafters. Launched into the gutters is the first row. The following rolls have a 10–15 cm cutter. Next, let’s talk about the skate. The membranes on the skate are fixed on both sides by cutting them along the upper edge. A strip is rolled along the skate along the skate, descending on one side of the roof and then the other. It appears to be a coating that directs water flow to the gutter that is shaped like water.
Vapor barrier: guidelines for its installation
It is beneficial to discuss vapor barrier separately. It ought to be a membrane as well. Film made of polyethylene or polypropylene is inappropriate because of differences in her properties. This layer’s vapor permeability (measured in g/m 2) ought to be very low. ideally, it should be zero. That is, pairs from the room shouldn’t be able to enter the insulation layer through this layer. This is crucial to remember when using mineral wool as insulation: when it gets wet, it loses more than half of its properties; when it gets frozen and melts, it typically crumbles into a dust.
As a result, when one panel enters another, the vapor barrier film is also laid. Additionally, a unique bilateral steam-permeable tape—which resembles sticky rubber—is used to glue these joints. It won’t do to use standard stationery or painting. They don’t offer complete steam protection. Every adjoint is glued in addition to the joints, from below, from the sides, and from above.
The vapor barrier has a line applied to it. She points out the border, where the next layer starts (the zeal’s size), and the tape-fastened line where the canvases are placed.
Typically, the vapor barrier is fastened to the lags of stapler brackets or, as shown in the figure, to the inner crate’s strips for casing installation. Another venturezor is created in this instance, and it will dry the membrane and finish. Although not necessary, this gap is preferred. The lining can, in theory, be put directly on top of the membrane.
There is a challenging and clear-cut answer to the question of which is better for insulating the damaged roof. Use only hard mineral wool with a density of between 30 and 50 kg/m^3. Soft materials can slide because the attic roof typically has a steep angle of inclination. It is preferable to take slabs because of this. However, in this instance, the steps will need to be adjusted to the insulation’s dimensions: the material should be 10-15 mm narrower than the stove’s width in order for it to "display" between the beams and hold firmly.
To install thermal insulation in order to minimize cold bridges. Typically, 200–250 mm of mineral wool are needed for central Russia. There are multiple mat layers here. The slabs are positioned so that the seams of one row overlap the next when laid between the rafters. As was previously mentioned, the insulation’s width should be marginally greater than the space between the rafters. After that, the plate tightens up without any cracks. Should the width be greater or less, the material must be cut. In addition, there are plenty of leftovers and little chance of gaining an even edge.
In the event that the rafters’ dimensions prevent the installation of all the insulation, the necessary thickness of planks is installed from one side of the room to the other. The remnants of the insulation are laid between them. It already has a vapor barrier and, if needed, a finishing crate attached. This is an even better option because even the rafters are blocked by completely excluding cold bridges. Although installing this method will cost a little more, the attic will undoubtedly be warmer, saving on heating expenses.
How to insulate the attic roof: work order
The attic floor device works well, allowing you to extend the construction period. The superdiffusion membrane, a crate, and roofing material must all be fixed onto the rafters right away. And eventually, the attic’s insulation can be completed from the inside.
But take note: the waterproofing layer needs to be installed concurrently with the roofing. The primary error made by many developers is that they fail to lay this membrane. Consequently, one must either take off the roof and install it again or devise methods to fix this flaw. The main issue is that, in this instance, there isn’t a low-cost solution that ensures the materials’ normal state.
If everything is completed at once, the task order is as follows:
- From the side of the room, a crate across the rafters is filled – thermal insulation will be on it, instead of a crate, a cord or galvanized wire is sometimes attached;
- The heat -insulating material is laid on it from the roof (according to all the rules, displacing the seams, making sure that there are no cracks);
- A superdiffusion membrane is rolled over thermal insulation;
- a crate is stuffed;
- roofing is laid;
- From the side of the room, vapor barrier is fixed and glued;
- with or without a finishes with a crate.
The exterior attic roof insulation is simple to install; thermal insulation is stacked on a crate and pushed in from below.
Working with the insulation is not difficult with this option because it is simple to lay and rests on the crate (laces).
With this option, you can delay interior decoration for the necessary amount of time (which is helpful if money is tight). Following rafter system installation, you must do the following:
- roll out and fix the waterproofing;
- fill the crate (if necessary, the counterparty);
- mount roofing material.
This completes the work that is required for the first step. You must insulate the attic roof from the inside once you have the chance to do so. Working will not be as convenient because you will need to build a protective structure to prevent the insulation from protruding higher than is required. Vata will need to make some sort of correction because he is trying to topple over. The following is the work order:
- Between the lags with a step of 40-50 cm, fill the strips that will retain thermal insulation, providing the required venturezor;
- Thermal insulation of the required thickness is laid and fixed (the rules remain the same);
- a crate is nailed, holding the layers of insulation;
- The vapor barrier membrane is covered and glued;
- The crate and finishing material is mounted.
It’s also simple to insulate the attic from the inside if you use plates.
Several remarks regarding the application of the thermal insulation material. Everything is rather easy to understand if these are mats made of high-density mineral wool and if their width is slightly greater than a step between the lags. This is because they hold well on their own.
It gets more complicated if mineral wool is laid in rolled form. The attic roof is insulated from the inside out, working from the bottom up. Grab a construction stapler and some lace. Roll out the cotton, press it against the strips, use brackets to secure a piece of lace, and trace the letter Z. Therefore, address the first layer, followed by the second and all others.
In general, mineral wool mats with the necessary density of 30–50 kg/m 3 are preferable if you want the attic roof to be warm. They are sufficiently hard to maintain their shape. The thermal insulation of the attic roof deteriorates when softer rolled materials settle down on steep slopes or vertical surfaces.
The results of placing rolled mineral wool with insufficient density are as follows.
The better to insulate the attic roof
Mineral wool is the most widely used material for attic roof insulation, as was previously mentioned. She is good, but she has one major flaw: she fears the wet. It needs such extensive defense against all threats because of this in order to maintain its characteristics.
Covered the roof with epx, or polystyrene foam that has been extruded. While foam (PSB-S-S-35 and PSB-S-S-25 brands) has good qualities, it can identify harmful substances when burned. However, self-substituting stamps are available (with special additives). It is preferable to utilize them for insulation purposes on roofs.
The foam’s primary benefit is its inexpensive cost. It is easily mounted by sandwiching it between rafters and caulking all of the joints. Making foam insulation for the attic from the inside is convenient. Simply order plates that are 10 to 15 mm larger than the lumen between the rafters and tightly install them. Their elasticity makes them incredibly durable.
In addition, the roof provides waterproofing and a gap for ventilation. However, it shields a greater amount of wooden structures because the polystyrene foam practically absorbs moisture and does not let steam conduct it. This is the primary disadvantage. Given that the pair fails the material, the attic needs a good ventilation system, which will incur additional expenses.
The best properties of EPPS are that, in the same conditions, its thickness is 1.5 times less than that of foam and half that of minvates of the specified density. In addition, he has a castle system that lessens the possibility of openings that could allow heat to escape. Another benefit is that mold and fungi cannot grow on extruded polystyrene foam, nor do mice or insects like it. Its application is limited by its solid price. Furthermore, we require a ventilation system.
EPPS stamps: Teplonitis, Kinplast (Kinplast), Styrofoam (Stirophom), Extroll, Stirepex, Foamyks, URSA XPS, Technoplex, Primaplex (Primaplex), and Greenplex (Greenpex). When making a decision, consider the differences in characteristics even though the technology is the same.
Foamed polystyrene foam is a new kind of insulation that has just recently become available. When applied to the surface in liquid form, it reacts with the air and grows larger and larger until it fills all the gaps and forms a single, monolithic layer. If a waterproofing layer was overlooked during roofing installation, this may be the only method available today to fix the problem and warm the attic.
This is the foamed polystyrene insulation process (left) and the outcome that was achieved. Excesses are reduced to the lag’s level.
Although this insulation requires a unique application technique, it has good characteristics (thermal conductivity coefficient 0.036-0.040 W/m² ° C). A closed cavity that the composition will be flooded into must be set up. The lateral components of the attic roof are called rafters, and sheet material (such as plywood, glv, and fiberboard) is nailed to them from both above and below.
When the supply sleeve is inserted into the educated cavity, pressure causes the cotton wool to become loose. It creates a single layer of insulation by filling in all the gaps.
The attic roof insulation process is a global one.
When compared to all the heaters mentioned above, the primary benefit of the ecovy is that it conducts pairs. to give moisture after absorbing up to 20% of the volume. This means that, as with wood, humidity is naturally regulated, negating the need for a vapor barrier. The appropriate organization of air masses within the ventilation gap between the roof and insulation should persist.
This information is the most understandable and compact.I want to insulate the roof that partially captures the second floor.About 1.7m on the upper vaults of the 2nd floor.The attic is above.The house was bought in the pre -missing version, now I"m opening these arches.The builders simply knocked out a Ursa there without a ventilationzor.In winter there was condensate, mold went in places.I will make insulation according to your recommendations.Upon an autumn arises with the attic.Leave it not insulated or insulate along with the arches of the 2nd floor.The fact is that in the house there is only forced ventilation.I consulted.I was advised to install 6 aerators in the skate.The attic area is about 80 m² .I want to ask, this will help?Or leave the attic cold and deaf?Simply put the air through the venti -zors will rise to the attic and go into the gap on the skate.And further.There are no holes in the cornices, it is filled with lining.I think the perimeter around the perimeter around the cornice of the hole for the air flow.Your opinion, if it does not complicate.Thank you
It’s possible to leave the attic cold if you don’t intend to live there. Ventilation will then be simpler to accomplish. Everything goes exactly as you had hoped: the attic space will have natural ventilation thanks to the aerators. Exhaust ventricels must stop in the attic rather than be removed to the roof at the same time. The zargiad air will then pass through the actual aerators from this point on. The issue of ice overgrowing the channels vanishes in this instance.
There is always an allure to use the attic for housing. The attic room needs to be heated in order to be comfortable. It can be completed with various materials and from both the inside and the outside.
The instructions for warming the attic roof
The roof structures typically place limits on the attic’s dimensions. Furthermore, the attic is frequently not enclosed with load-bearing walls and thermal insulation for drainage. As such, extra caution should be used when insulating the attic roof.
Attic roof before insulation
Do It Yourself AT
It is quite possible to insulate the attic roof independently. But it’s important to keep in mind the specifications for this kind of roof’s design:
- The roof of the attic roof involves the use of light materials to reduce the load on the rafter system. For example, natural tiles are inappropriate for her;
- For insulation and insulation of the attic roof, effective lightweight materials should also be selected, which will reduce the weight of the structure;
- A large role in the roofing system of the attic is played by ventilation. Any puncture in development or installation will lead to an increase in humidity in the living room, a decrease in the properties of insulation and damage to elements of the supporting structure.
Technology for insulating attic roofs
This kind of roof insulation can be installed from the inside or the outside. Though each approach has benefits and drawbacks, external thermal insulation is thought to be the best option because of its better outcomes.
The exterior attic roof insulation
Private residence with a floor in the attic that is currently warming up outside
The preparation of the work area, the laying and fixing of materials, and thermal insulation installation for the attic roof are all relatively easy tasks.
- The lower part of the rafters is filled with plywood, OSB or a trimmed board.
- Stack the vapor barrier layer on top. Its canvases and docking places with the structure must be glued with foil tape. When installing this layer, it is important not to confuse the side of the material: vapor barrier functions in one direction.
- The next layer is a heater. When laying it, it is important not to leave the voids.
- Next, we spread over the rafters of the hydraulic tank. We also glue the material of the material with special.
- Then you need to make a ventilation gap. To do this, a rack with a height depending on the type of roofing is mounted on a hydraulic boar of rafters. Wave roof involves a rail of 20-30 mm, flat-50 mm.
- At the last stage, a crate and roofing are installed.
The interior insulation of the attic roof
The picture shows the attic roof before internal insulation
With the room shielded from atmospheric precipitation, the internal insulation of the attic roof appears to be a more sensible approach, but it still has a number of drawbacks:
- Most of the heater is elementaryly inconvenient to mount from the bottom up, and it is almost impossible to lay out and fix the roller materials;
- Often the rafter system is strengthened by various connections and runs, in the places of conjugation of which there remains unprotected thermal insulation of the void. This forms cold bridges, respectively, the insulation of the attic roof works poorly.
The attic roof’s internal thermal insulation happens in the following ways:
- Starting from the lower edge of the roof, lay out the waterproofing film overlap, fasten the edges with adhesive tape. At the walls, this coating should have a small supply, and the excess after the end of the installation work is removed.
- To ensure a ventilation gap, as well as a high -quality fit of the film to the roof material, we navigate the counterracies to the rafters.
- Then tightly, without gaps, lay out the insulation, for example, mineral wool.
- Further, the entire space is sewn up by a vapor barrier membrane. It is fixed using construction brackets.
Putting foam on the attic roof
One method of utilizing polystyrene to insulate the attic roof
One of the most widely used heaters for thermal insulation of foundations, facades, and attic roofs is foam, also known as polystyrene foam. Read our instructions, which walk you through each step of using polystyrene to insulate your attic roof, if you are unsure how to do it.
This material offers a remarkably large array of benefits.
- low cost;
- sufficiently high resistance to stretching and compression;
- small weight;
- wear resistance (resistance to mechanical influences and temperature differences);
- high indicators of moisture and fire resistance;
- easy installation;
- Operating service life is from 25 to 80 years.
The following is how foam insulation for the attic roof is applied:
- From wooden elements of the roof structure, we remove protruding screws and nails;
- We put the waterproofing film on the rafters, fasten it with the help of a furniture stapler. If we are talking about the finished structure, the film is laid not on the rafters, but through additional rails.
- Then, between the rafters, sheets of foam are laid out, each of which is adjusted with a knife for the density of the fit and elimination of the gaps. You can fix the insulation with wooden rails, glue or special dowels with wide hats.

Repair of a damaged attic roof insulation
The damaged attic roof needs to be properly thermal insulated because of the following features:
- The vapor barrier is mounted from the inside of the attic room with a continuous carpet. Joints are sealed with special tape;
You can observe how to insulate an attic with a broken roof in the video.
Supplies for the attic roof’s insulation
The material that is used for the attic roof’s thermal insulation is primarily determined by the climate in your area. Every insulation has a unique required thermal insulation layer based on its heat engineering properties.
Polyurethane foam is one of the best choices for attic insulation from the inside. The installation of this material is depicted in the photo.
Think about the popularity of heaters:
- The most common and high -quality attic roof insulation is basalt cotton wool. Its installation is carried out in two layers, with the overlap of joints. Most regions require laying a layer of 150-200 mm;
- The next most popular is polystyrene foam. Its necessary thickness is determined by the characteristics of the brand of the product;
- Modified mounting foam – polyurethane foam. This material allows you to solve the issue of roof insulation from the inside. It can be applied with a smaller layer due to its thermal properties. It also differs in a high level of adhesion and well fills the voids of the structure;
- Contrary to the prevailing opinion, URSU is not recommended to be used as a heater of the attic roof. The layer of this material necessary for thermal insulation is almost impossible to fix. In addition, after a while it can “slide” the structure, if the installation surface is inclined.
This video will teach you how to use readily available materials to insulate the attic roof with your own hands. There are also the required blueprints and sketches available.
Insulating an attic roof yourself is a fairly simple process that doesn’t require expensive materials or extensive professional training. Any attic roof can be arranged and insulated with great quality and durability with a little construction knowledge and deft hands.
