Installation of a sandwich dummage: how to assemble and installation with your own hands

A sandwich panel roof system is a cost-effective option for many homeowners who want to increase the longevity and insulation of their roof. Sandwich panels provide good weather resistance and thermal performance because they have a core material sandwiched between two metal sheets.

The first step in assembling a sandwich panel roof is preparation. To calculate the required number of panels, start by taking precise measurements of the roof’s dimensions. Ascertain that all required instruments and supplies, such as panels, screws, sealant, and safety gear like goggles and gloves, are available.

Starting at the eaves, install the panels starting from one end of the roof to the other. Using screws, firmly fasten each panel, making sure that the panels line up correctly to preserve structural integrity. To stop water from seeping through the joints, particularly in locations that frequently experience heavy rain or snow, use an appropriate sealant.

It’s essential to adhere to local building codes and manufacturer instructions when installing a do-it-yourself project. This guarantees that the roof satisfies safety regulations in addition to being functional. Handling and arranging the panels can be made simpler by working with a partner, particularly on larger roofs.

Check the entire installation for any gaps or loose fittings after the panels have been secured. Where necessary, make the required corrections and add more sealant. When properly cared for, a sandwich panel roof can offer dependable security and long-term energy efficiency.

Assembly of a sandwich dummage

An overview of the benefits in brief. Though there are many options, the sandwich dummage is the most commonly used in Russia’s private housing construction. The design of a chimney that promises both safety and ease of use is crucial.

A chimney of this type consists of two pipes of various diameters that are inserted into each other; the space between them is either left open or filled with non-flammable insulation before installation begins. A chimney like this can be installed quickly, weighs less overall, has perfectly smooth interior walls, produces good thrust, and produces very little soot.

The most crucial point to remember is that installing a chimney requires specific preparation. You get a document known as a "passport" when you purchase one of these units, and it serves this purpose. Typically, there are thorough installation instructions along with a schematic picture.

This video clip clearly illustrates how to mount the chimney from the sandwich pipes correctly and guarantee its dependable operation:

You should show your chimney to a specialist if it has a complicated device to ensure that it is functional and dependable for this design:

How to withdraw a chimney through the inter -story floor

Because the temperature of the smoke gases is unreasonably high, any chimney is always the most dangerous place to start a fire. Furthermore, there may be dangerous repercussions for even the smallest infractions when it comes to the installation of a chimney inside a residential building.

Therefore, a ceiling and passing node must be made or purchased in order to arrange a chimney’s passage through wooden structures. It needs to match the pipe’s outer diameter precisely. The chimney is set back from all the closest surfaces that could potentially come into contact with it because of its design:

Of course, the simplest solution is to buy a factory-made chimney unit and just wrap the heat-insulating material around it from all sides. If basalt wool is of a very high caliber and can tolerate high temperatures, that would be the best choice. Consequently, you should confirm with the manufacturer that cotton wool can be used up to 800 degrees Celsius before making a purchase. Such cotton wool is naturally more expensive than normal, but as you probably already know, there’s no reason to cut corners.

For an interstory node, the following is an option for creating an asbestos-cement box:

The current SNiPs state that a minimum of 38 centimeters must separate the internal sandwich pipe from a wooden structure when the chimney is passing through a wooden coating. Additionally, the box needs to be filled with specific material rather than being empty.

Yes, of course, there are instances when maintaining this tolerance is impossible due to the spacing between the rafters; in these cases, you will need to add more bars to the opening. In order to safeguard the rafters and lags of a wooden structure, it is advised to use asbestos canvas or galvanized sheeting that is at least 5 mm thick. The benefits of the galvanized sheet lie in its ability to evenly distribute heat and stop it from concentrating in one area. Additionally, it reflects and shields the pipe’s inflexible thermal radiation.

This is the sandwich’s primary benefit, as placing a regular steel chimney would require a minimum of 50 centimeters between them.

The following metal-strengthening goods will assist in maintaining the pipe’s upright position:

How to protect the junction of a chimney with a wooden overlap?

We’re going to talk about the most crucial point now, which will help you prevent an entirely unplanned fire.

Therefore, the sandwich pipe heats up more and exposes all the surrounding structural elements to temperature changes as the flue gas temperature rises. As such, it is crucial to ensure that the passage elements are consistently safeguarded. Additionally, don’t assume that anything is that easy.

For instance, at 200 degrees, a typical tree without any special protection is already charged. Furthermore, dried wood has the ability to ignite at 270 degrees Celsius! Wooden lags can also light up if they are subjected to 170 degree heat for more than a day. Unfortunately, even if a high-quality sandwich pipe is installed, fires frequently start at this exact moment, which many people are unaware of.

As a result, it’s best to complete the overlap with thick enough insulation to ensure that heat from the pipe virtually never reaches the wall or wooden components. Furthermore, the more the wooden overlap itself retains heat from the sandwich, the more adversely the wood will feel the heat over time. Of course, a standard insulation in the PPU node cannot reach a critical temperature in an hour or two, but the issue lies in the fact that heat changes the chemical composition of wood and insulation materials over time. To use the language of the liver.

For instance, wood can ignite at 130 degrees if it is heated continuously and for an extended period of time! However, it frequently reaches as high as 200 degrees on the sandwich’s exterior (from 75 to 200, as laboratory tests showed). That’s why it’s so tragic when a stove or fireplace successfully drowns for almost a year. Up until that point, everything was perfect. Then, one day, the hosts sank for just two hours longer than usual—to warm up on a particularly chilly winter’s evening or to dazzle guests—and the temperature in the sandwich surpassed the critical point, reaching the overlap at 130 degrees Celsius.

Additionally, exercise caution if using mineral wool as the PPU’s thermal insulation material. Its characteristics also change with time as a result of exposure to high temperatures, and it even becomes more thermal pipeline! This does not imply that cotton wool will ever catch fire, but the chimney’s exterior shape here will already be substantially hotter than you had anticipated. However, this is a component that was overlooked at first!

Because of this, knowledgeable stoves advise against isolating the ceiling too densely because the denser the isolation, the more heat it retains internally. Furthermore, it’s critical that there be a natural way to blow air into the pipe:

Additionally, they frequently commit a risky mistake by estimating the distance between the rafters incorrectly, which deviates from the standard and allows the pipe to pass through. Please be aware that the worst choice is an empty ceiling node without any thermal insulation installed.

Take into consideration that the material covering the chimney’s inner arc has a tendency to settle. Consequently, the intersection of two walls is occasionally exposed. And now, it will be nearly impossible to put out the fire that started in such voids if this joint burns out (and it is particularly dangerous if it is also located inside the ceiling). Consequently, a thorough inspection of each of the sandwich dummage’s passage nodes should be conducted once every year or two.

The simplest version of a sandwich falling through the ceiling is arranged correctly as follows:

The entire installation should resemble this if a water tank is placed on a chimney:

Take note of the proper way to pass a sandwich pipe through the ceiling:

Lastly, you will require a special tee if a stove or fireplace cannot be used to place a sandwich pipe directly to the excretion site:

Organization of the node through the walls of the house or bath

There are now two primary methods for installing a chimney sandwich: inside the home or on the street. In fact, chimneys are increasingly frequently installed directly through the wall to the street, and from the first floor, they are already oriented upward and vertically. This has a deeper meaning because it allows the chimney to cool much more quickly and avoid passing through the roof and the fire-safety floors. However, the chimney that rises through the attic typically acts as an extra heat source. But naturally, there will already be a higher chance of fire here.

You might be shocked to learn that, given the temperature of a single-circuit chimney, the exterior of a sandwich made of stainless steel is actually relatively recent. Since the purpose of this type of chimney was originally to increase traction, the gases that emerge from the furnace typically have a temperature of 800 degrees Celsius, and the exterior casing can get as hot as 300 degrees! Furthermore, this surface is by no means fireproof.

The contemporary sandwich dizzy is taken out through the residential building’s walls and roof:

You can examine the knot in greater detail by looking at this illustration:

Thus, the following detailed instructions will assist you in organizing the proper angle of passage for a sandwich dummage through the walls:

• Step 1. Before starting work, be sure to calculate the length of the horizontal sandwich pipe, which will need to be passed through the wall. And take into account the tee that you will install. Calculate the roof slope so that the chimney then does not turn out to be too close to the cornice.
• Step 2. The box that you insert into the wall, fill it with non -combustible basalt material.
• Step 3. Close the passage knot with a lid so that a gasket made of basalt cardboard remains visible.
• Step 4. Close the edges of such a lid of the node from the components of the external decoration of the house, for example, siding.
• Step 5. Process the edges of the box colorless roofing sealant.
• Step 6. At the exit from the chimney from the wall, set the revision.
• Step 7. Fasten the chimney using special wall brackets, one for each 1.5-2 meters.
• Step 8. So, after you installed the pipe, check its verticality using the level.
• Step 9. Be sure to ensure that the seam is deployed to the house.

The most crucial guideline is, after all, to provide the greatest amount of fire protection at the point where the chimney joins the house or bathroom wall. This is a nice illustration of one of these nodes:

The metal corner must properly support the horizontal element of the sandwich dummage in order for it to be installed with reliability:

Moreover, unique designs will support the installation of such a chimney in a strictly vertical position against the wall:

Believe me, the work is far from done at this point, particularly if your chimney has a complicated design (which is not something we strongly advise):

A sandwich panel roof is a doable do-it-yourself project that can improve the longevity and energy efficiency of your house. You don’t need a lot of building experience to finish this task if you follow a few important steps.

Prior to starting, make sure you have all the required equipment and supplies on hand. This covers the actual sandwich panels as well as any necessary insulation, sealants, and fasteners. Setting these up ahead of time will help to minimize disruptions and speed up the installation process.

Start by giving the roof surface a thorough cleaning. Make sure the surface is dry and clean by clearing away any debris. In addition to providing a stable base for the sandwich panels, proper preparation helps avert potential problems like leaks or instability.

After that, take precise measurements and cut the sandwich panels to match the size of your roof. For a tight, weatherproof seal to be achieved, accuracy is essential. Employ the proper equipment, such as a circular saw or nibbler, and adhere to the cutting methods and safety regulations recommended by the manufacturer.

After the panels are sliced, gently lift and place them over the roof framework. Use the suggested fasteners to firmly fasten each panel, making sure they are spaced evenly and tightened in accordance with the guidelines. To stop water from seeping in, pay attention to any overlapped edges and seal them with the proper sealants.

Check the installation for any gaps or loose fittings after the panels have been secured. Deal with any problems right away to protect the integrity of the roof. Lastly, make sure the roof is operational by giving the area a thorough cleaning to get rid of any construction debris.

You can confidently install a sandwich panel roof by adhering to these instructions and exercising caution at every turn. This project improves the structural integrity and long-term energy efficiency of your house in addition to its visual appeal.
