Mineral wool slabs density

The density of mineral wool slabs, which are frequently used for insulation and roofing, varies based on the intended use and performance standards. Density plays a major role in determining how well these slabs insulate against heat and sound. Density is essentially the measure of how closely packed the mineral fibers are inside the slab. Because higher density slabs can trap more air pockets and have greater mass, they usually have superior thermal and acoustic insulation qualities.

Mineral wool slabs’ density affects how well they can withstand compression under load in roofing applications, which guarantees long-term performance and durability. Higher density slabs are frequently chosen for applications requiring strong insulation that won’t compress too much under the weight of foot traffic or other loads.

Understanding density is helpful in selecting the appropriate product for a given set of thermal resistance (R-value) requirements when choosing mineral wool slabs for insulation. Lower density slabs can be appropriate for residential settings with standard insulation needs since they offer sufficient thermal protection without adding weight or cost.

A variety of densities are frequently offered by manufacturers to meet different building codes and performance requirements. This versatility enables developers and contractors to choose slabs for residential construction, commercial roofing, or industrial facilities that satisfy project-specific requirements as well as legal requirements.

Mineral wool density: high and low density mineral wool

We made the decision to insulate your home or apartment. For these uses, experts advise using mineral wool since it is the most dependable and high-quality insulation available. This substance not only retains heat within the home but also reduces outside noise and produces a peaceful, quiet atmosphere. The properties of the mineral wool have a direct bearing on insulation quality. This article will address a property like the density of mineral wool.

To ensure that the material satisfies all of the requirements, the density of the mineral wool must be ascertained. The higher the density, the more expensive the insulation will be because the density is influenced by the number of fibers in the material, and achieving a high density will result in increased material consumption during production.

The density of stone wool is determined by a weighing 1 m3 of the material. Different representatives provide products of different densities, it depends on the technological processes used. Naturally, when choosing a material, it is necessary to take into account the features of the building or premises where sound insulation and thermal insulation will be carried out. For insulation of multi -storey residential buildings, mineral wool is used by a density of 35 to 40 kg/m3. More dense materials are used for thermal insulation of production facilities. There are special formulas by which the specialist correctly calculates the density of mineral wool necessary for high -quality insulation of a particular structure. There are different types of mineral wool used for different purposes, and each of them has its own density.

Mineral felt ranges from 100 to 150 kg/m3, mineral mats from 100 to 200 kg/m3, semi-rigid plates from 70 to 300 kg/m3, and hard slabs from 100 to 400 kg/m3. Stiff slabs are used to warm coatings, walls, ceilings, and refrigeration units in both commercial and residential buildings because of their high density. Another crucial feature that guarantees this is the extremely low thermal conductivity of mineral wool.

The heater’s density is higher than

Insulation density is a property that primarily influences material utilization. For instance, low density insulation such as ISOVER Classic, ISOVER KARCAS-P32, ISOVER KARCAS-P34, ISOVER SUBLECTION, and others can be used for thermal insulation of light coatings, floors between floors, attics, and hinged facade systems. A density of 12–20 kg/m3 is sufficient to use plates and mats as intended. By the way, other products are used in thermal insulation work in addition to plates and mats. Which ones, refer to the article’s mineral wards.

If you need to apply a plaster layer, ventilated clearance insulation for walls, or insulate a pitched or flat roof, you must select a material with a density of 50 kg/m3. These are the standard and difficult ISOVER PLATs: ISOVER OL-TOP, OL-P, OL-PE, OL-E, OL-E, ISOVER PLACK FACADAD, ISOVER Ventfasad.

Density of Ursa insulation

The high strength indicators, dependability, durability, and non-hygroscopic nature of URSA heat-insulating plates make them ideal for warming a variety of building components, including floors, roofs, facades, and the thermal insulation of foundations and subterranean chambers.

Low density products are made by the Ursa manufacturer. There is a misconception that high-density insulation must be used in order to guarantee a high level of thermal insulation. However, this isn’t always the case. Depending on the intended use, the material’s density is chosen. The size of mineral wool is precisely the same as this. This feature is also crucial for the material’s use under specific circumstances.

The Ursa Glasswool facade has the greatest density (35 kg/m3) of mats. They are applied to ventilated air gap insulation systems. You can therefore use high density material here. This material is no longer appropriate for use with frame partitions.

The KNAUF heater’s density

In general, the producer of mineral wool insulation, Knauf, depends on the walls, if needed, pitched and flat roof insulation, attic and interstory floor thermal insulation, and thermal insulation structures that do not load. For this reason, the density of every product is low. For instance, the heat roof material 037A, which has a density of 18 kg/m3, is used to insulate the roof. Teplorolon 040, on the other hand, is ideal for isolating interstory ceilings because of its low density of just 12 kg/m3.

When used as an inner layer, the density of mineral wool slabs ventilated facade thermo plate 032 (34 kg/m3) is sufficient to insulate the outer walls from heat.

Density of Rockwell insulation

The manufacturer Rockwall offers slabs and mats with a density of 20 to 30 kg/m3 for heat and sound insulation of ventilated coatings, roofs, attics, walls, suspended ceilings, floors on lags, frame walls, and partitions. But, you can use Panelrock, a plate with a density of 65 kg/m3, to insulate the exterior walls of buildings from heat and sound. The manufacturer and minvat have 161 kg/m3. These are Stroprock plates that overlap beneath a concrete screed to insulate ground floor surfaces from heat and sound.

The questions of mineral wool types, density dependence on manufacturing technology, and density of specific mineral wool types are covered in the article.

Mineral slab for insulation of the house – technical specifications

The most common heat insulator, mineral wool has been used extensively in both large-scale and custom construction for many years. Technology advancement must improve this material’s operational characteristics. Manufacturers now provide mineral wool plates with a range of features for sound and thermal insulation of roofing and building structures. You must know how to select the appropriate mineral fiber insulation if you want thermal insulation to fully meet the calculation requirements.

Using a slab of mineral wool for roofing pie

The scope of application

Rocks with a volcanic origin, domain slag, and melted glass are used to make mineral wool. Fibers are extracted from the melt with the aid of centrifuges, and they are combined with a synthetic binder. The resulting mass is formed into mineral-fluid plates that vary in size, density, and stiffness.

Mineral fiber thermal insulation slabs are used to block heat and sound.

• floors;
• rocky and flat roofs;
• roofs of three -layer panels;
• sexes;
• ceilings;
• partitions;
• three -layer walls of a lightweight type of block materials (mineral wool is laid in the middle of the structure);
• frame walls;
• facades (when warming for plaster and as part of ventilated hinged facades).

Basic properties

The thermal insulation qualities of the material, as well as its density, moisture resistance, vapor permeability, and fire resistance, must be considered when selecting insulation for the ceiling, walls, floors, or roof.

Mineral wool is one of the least expensive heat insulators and has a high level of resistance to noise and cold. However, you should ascertain the criteria used to assess a heater’s suitability for installation under particular circumstances before making a purchase.

Advantages of fibrous insulation

Slabs of mineral wool are distinguished by:

• small specific gravity – insulation with this material will not overload the structure;
• high strength (this indicator depends on the density of the plate);
• fire resistance;
• bio resistance (the material is resistant to decay, unattractive for pests and rodents);
• durability (operational period, subject to the correct installation exceeds 50 years).

A comparison of the thermal insulation materials’ thicknesses

The material leads the heat insulator market due to its superior technical qualities.

Because of its fibrous structure, code heat insulation made of mineral wool offers good resistance to heat leakage. According to GOST 4640-2011, thermal conductivity indicators range from 0.036 to 0.042 W/(m • K) at a temperature of 10 °C to 25 °C, depending on the type and purpose of the plates.

High fire resistance materials are referred to as mineral wool because they don’t catch fire from unintentional sparks or help a fire spread. Fibrous plates can be in contact with air that is heated to 750 °C and surfaces that are heated to +400 °C.

If basalt fiber is not mixed with combustible synthetic materials as filler, non-combustible plates made of it can resist two hours of exposure to an open flame at 1000°C.

The block is more resilient and better able to tolerate deformation stresses under load when its density is higher. There is a distinction between the following kinds of mineral wool plates:

• Soft plate (40-55 kg/m3, brand PM-40 and PM-50);
• Semi-rigid plate (60-90 kg/m3, brand PP-60, PP-70, PP-80);
• Hard plates (100-150 kg/m3, brand PZh-100, PZh-120, PZh-140);
• high stiffness slabs (160-210 kg/m3, Mark PSH-160, PPH-180, PPH-200);
• Solid plate (220-300 kg/m3, brand PT-220, PT-2550, PT-300).

Attic slabs made by hand

Slabs of mineral wool are susceptible to moisture. While the fiber’s strength and other characteristics remain unaffected, the presence of moisture in the material’s structure causes a significant rise in the material’s coefficient of thermal conductivity, ultimately leading to a decline in its operational properties. Hydrophys of the material is made possible by the use of specific fillers. The GOST states that an insulation’s water resistance should have an average pH of 4–7.

In contrast to heat insulators made of other materials, mineral wool has the highest vapor permeability. (m*hour*PA) = 480*10-6 g/is the indicator. Mineral wool insulation allows for the preservation of gas exchange through structures, creating a comfortable microclimate within the space, in situations where an impermeable vapor barrier is not present (such as external wall insulation for plaster) or where a gas-permeable membrane is employed.

Using vapor barriers to keep moisture out

The advantages of slab insulation

The mineral plate stands out for more reasons than just its superior functionality. Blocks are easy to mark and cut to size because of their structure, which also helps them retain shape.

Heat insulators can be mounted quickly and easily on soft, semi-rigid, hard, or hard blocks. Typically, they are placed in the spaces between floor lags and roof rafters, or in the cells of walls or ceilings. Hard mineral wool slabs are placed on a prepared surface for external thermal insulation of flat roofs, and fasteners with "umbrella" hats are used for external thermal insulation of walls.

Putting in boards in between rafters

One more benefit to be mentioned is the material’s reasonable price.

Ministry of Plutus: types and technical parameters

Technical indicators on mats made of mineral fiber vary depending on the following:

The range of applications for a heat insulator with specific qualities must be considered when selecting an insulation material.

Different types of insulation for slabs

There are three types of thermal insulation mats: stone cotton wool, slag, and glass wool.

The least expensive insulation option is glass wool. The same materials used to make glass—dolomite, limestone, drill, sand, and soda—are also used in the manufacturing process. The fiber measures 15–50 mm in length and 5–15 microns in thickness. The operating temperature range is -60 °C to +450 °C. The heat-shielding qualities of glass wool are diminished when time creams are added. Wearing protective gear is essential when working because broken fibers are prone to breaking during installation. In order to prevent glass dust from entering the room, it is also crucial to seal the insulation using a steam barrier.

Because blasting slag is used as the raw material in its manufacture, the slag has a low level of environmental safety. It is not advised to use the material for internal insulation in residential buildings because of this. The fiber measures 16 mm in length and has a thickness of 4–12 microns. Slag is not a good material for external building insulation because it absorbs water easily.

It’s a slag roll.

The safest and most efficient heat insulator is basalt insulation, also known as stone cotton wool, because its particles do not fall into the air during installation and they essentially do not crumble. Stone fiber material is also claimed to be hazardous to the environment if phenol-formaldehyde resin was not used in its production. However, the product is very valuable.

The Ministry of Plutus occurs in terms of the structure of fiberity.

• with a chaotic arrangement of fibers;
• with lamella (perpendicular) arrangement of fibers.

With the lamella location above the material’s exposure.

Marking

The density determines how the mineral wool is marked in accordance with established standards. The extent to which the material can be applied is impacted by the same indicator.

Table: Recommended scope and types of plates

Modifications for the ease of styling

The installation of insulation flooring is linked to the configuration of a multi-layer system, which may include a windproof screen, steam and moisture insulating barriers, and the creation of a thermal insulation barrier on vertical or inclined structures.

On complicated surfaces, unique mineral fiber mats with an extra layer are used to make the installation of the insulation system easier:

• Grounding with a polymer film or fiberglass protects the heat insulator fibers from blowing with the wind;
• foil prevents the penetration of steam into the insulation and helps to maintain heat in the room due to the reflection of thermal radiation;
• The outer bitumen layer serves as a waterproofing protection that does not prevent steam.

Preference should be given to well-established brands, such as:

• Rockwool (heat and sound insulation of the Battts line);
• Knauf;
• ISOVER;
• EcoVER;
• Technonikol.

Features of the Rockwall facade insulation

Size range

The calculated thickness of the heat insulator must be considered when selecting mineral wool slabs. This parameter is impacted:

• features of the insulated structure;
• climate of the construction region;
• the location of the dew point;
• thermal conductivity of the block;
• The level of load.

The thickness and density of the plates that are recommended for use are specified on the packaging by the manufacturers.

Overweight insulation

These materials, also called mineral slabs, are produced in various categories based on their density. The semi-rigid PPZ GOST plates and panels P 75, P 125, P 175, and P 225 are available in the construction market. Industrial and private construction successfully employs all of these product varieties. There are differences between the panels.

• increased strength,
• resistance to destructive external influences,
• meet the requirements of environmental standards and fire safety rules.

A deeper understanding of the functional characteristics of stronger mineral wool insulation is warranted.

Basalt wool is used to create semi-rigid, hydrophobmed mineral slabs P 75, which have an average density indicator of 56–78 kg/m3. There are various panel subspecies within the range, with thicknesses ranging from 40 to 200 mm, as well as format variations. Material is used by project developers to insulate inclined, vertical, and horizontal structures.

Specifically, mineral slabs P 75 have demonstrated excellent performance in heat-sound insulation of ceilings, frame walls, and interior partitions, as well as thermal insulation of ventilated napal roofs. Apart from its technical attributes, this material is appealing due to its easy installation and low cost.

The material might be the greatest option when it comes to choosing insulation for the facade’s decoration using "Moky Plaster" technology. Since the Ministry of Pluts P 125 has a density of 80–100 kg/m3, the insulation places moderate loads on foundation bases and vertical structures, negating the need for additional strengthening measures.

P-175, or hard mineral wool plates, are frequently used in both commercial and residential building. The mineral plate can be used in panel technologies and as an equivalent for insulating horizontal, vertical, and inclined building structures. In multilayer roofing systems, hard heat insulation P-175 serves as an efficient lower heat-insulating layer. It is not prohibited to use materials for industrial equipment’s thermal insulation. This model’s textual insulation is affordable and accessible to a broad spectrum of users.

The density of mineral wool slabs P175 ranges from 145 to 175 kg/m3, and their thickness is 50 mm. It is determined that the material is suitable for use in especially critical areas by its ability to withstand large mechanical loads, including local ones. Slabs can be successfully installed on a wide range of building structures, just like earlier models. Because of hydrophobization, the insulation’s volume contains no more than 1.5% of moisture.

Due to the high rigidity of the P-225 Ministry of Health, there is a particular need for this insulation when warming coatings composed of profiled metal or concrete. Density (170-230 kg/m3) establishes the substantial weight of insulation for the facade, which needs to be considered when deciding on the material’s thickness and installation technique.

In terms of technical features and application types, the Ministry of Health’s PG-200 is comparable to insulation P 225. The ability to use it without concrete protective screeds makes a difference.

For your roofing and insulation projects to function as well as possible, selecting the proper density for your mineral wool slabs is essential. Mineral wool’s density has an impact on handling during installation, durability, and thermal and acoustic qualities.

Because of their compact structure, higher density slabs typically provide better acoustic and thermal resistance. They work better in areas that need better insulation performance, like cold climates or areas close to noisy environments, because they are more effective at reducing heat transfer and noise transmission.

On the other hand, slabs of mineral wool with a lower density are lighter and easier to handle, which can make installation easier and save labor costs. However, in comparison to options with higher densities, they might provide somewhat worse thermal and acoustic insulation performance.

The particular needs of your project must be taken into account when choosing the density of the mineral wool slabs. The ideal density depends on a number of factors, including the local climate, the desired level of insulation, and available funds.

Conclusively, comprehending the consequences of mineral wool slab density is essential for making knowledgeable choices regarding your roofing and insulation requirements. You can guarantee that your project achieves both efficiency and cost-effectiveness by striking a balance between variables like thermal performance, acoustic insulation, and installation ease.
