Rockwool thermal insulation will help protect the house from cold and draft. The brand's products are known all over the world. One of the largest manufacturers of heat and sound insulation offers stone wool insulation. Non-combustible and safe material helps to maintain an optimal microclimate and a comfortable temperature in the room.
Features of technology and production of insulation Rockwool Scandic
The first thermal insulation materials under the ROCKWOOL trademark appeared in 1937. Rocks have become the raw material for the production of heaters. Over the years of development, the company has significantly improved the technology for manufacturing thermal insulation, but the original product has remained the same. Basalt stone provides durability, environmental safety and non-combustibility of mineral wool. The molten raw material is transferred to a centrifuge, where thin, strong fibers are formed. They are arranged in a chaotic manner, but reliably intertwined with each other. The material is treated with water repellents to reduce moisture absorption.
Especially for the insulation of low-rise buildings, the company has developed a series of Rockwool Scandic products with characteristics that make installation work faster and easier. The material is created using Flexi technology. One edge of the insulation is able to shrink during installation, and then recover its shape. The width of the elastic section is 5 cm. For installers it is marked with a marking. Benefits of the new technology:
- Simplifies the installation of the slab into the assembled frame made of timber or metal rails. It is not necessary to cut the mineral board, it is enough to squeeze the elastic edges and tuck between the guides.
- Insulation does not require additional fastening when mounted on an inclined and vertical surface. The work can be performed by one person.
- A snug fit eliminates the appearance of cracks and cold bridges.
Another feature of the Scandic series is its high compressibility. The material can be compressed by 60-70%, and after removing the load, it returns to its original shape. This feature allows the slabs to be packaged compactly for transportation. The insulation is completely enclosed in a dense plastic wrap. The procedure takes place under vacuum. The compact package can be transported by light transport.
Advantages and disadvantages
The heat insulator has the following advantages:
- Low coefficient of thermal conductivity - the fibrous structure of mineral wool with many air spaces actively prevents the movement of heat and cold. Thermal insulation with basalt slabs provides a stable and comfortable temperature in the house with minimal heating costs.
- Vapor permeability - wet steam is present in every room. To maintain a healthy microclimate, it needs to go outside. The porous structure of the mineral insulation provides high vapor permeability of the material.
- Sound insulation - randomly located stone fibers and voids between them contribute to the attenuation of the sound wave. Rockwool boards are used to create soundproof partitions between rooms or floors and acoustic ceilings.
- Non-combustibility is one of the criteria for good insulation, fire safety.Stone wool slabs are fire resistant and can withstand temperatures above 250 ° C. They do not support combustion, do not emit smoke when heated. The material belongs to the fire safety class KM0.
- The ecological safety of the insulation is confirmed by the EcoMaterial Green certificate. The raw material for its manufacture is natural stone. The products are safe for human health and are recommended for installation in residential premises. In order to reduce environmental pollution, the company recycles waste basalt wool for the production of new insulation.
- Durability - strong interweaving of basalt fibers ensures that the shape of the slabs remains unchanged for the entire period of operation. Rigid mineral wool does not wrinkle or deform. With proper installation, its thermal insulation properties are retained for more than 50 years.
- Ease of installation and transportation - Rockwool slabs are of standard size. During installation, the frame is assembled with a step equal to the width of the material. Mineral wool can be easily placed in it, and thanks to Flexy technology, the laying process is accelerated. The compression of the boards in the package allows you to load more material during transportation.
- Resistance to biological and chemical attack - stone fibers are not affected by fungus and mold. They are not chosen by rodents for housing. Basalt slabs are resistant to most chemical compounds, but at the same time do not cause corrosion when in contact with metal.
Disadvantages:
- Mineral wool contains organic binders. The composition is harmless at the operating temperature of operation. Rockwool uses a small amount of binder.
- Basalt fibers during installation can cause an allergic reaction. It is recommended to lay and cut slabs with gloves, a respirator and goggles.
Basalt wool, due to special processing, has a low percentage of water absorption. But direct contact of the insulation with water must be avoided. Installation of thermal insulation must take place in dry weather. After installation, the plates are covered with a waterproofing membrane.
Dimensions of insulation of the Scandic series
The Scandic series products are available in two sizes, with several options for the thickness of the slabs:
- The standard option is a slab 800 × 600 mm, thickness - 50 and 100 mm. The number of sheets in a pack is 12 and 6 pieces.
- Insulation of XL size - slab 1200 × 600 mm, thickness 100-150 mm. The number of products in a pack is 6 and 5 pieces.
The manufacturer indicates that the pack contains from 3.6 to 5.76 m2 of mineral wool. The information allows you to calculate the required amount of material. It is worth considering the recommendations on the effective thickness of thermal insulation. For walls, it is 100-150 mm, for the roof - 200-250 mm. In the manufacture of products, the linear dimensions of the plates are strictly observed. Thermal insulation does not change shape during the entire period of operation.
Specifications
- Thermal conductivity coefficient - 0.036-0.039 W / m * K.
- Water vapor permeability - 0.3 Mg / (M * h * PA).
- The compressibility factor is no more than 30%.
- Water absorption - 1 kg / m2.
- Flammability group - NG.
Mineral wool is an excellent sound insulator. When properly installed, it reduces the noise level by 42-63 dB. Technical characteristics of Rockwool Light Butts Scandic insulation ensure its durability. Plates do not lose their properties for about 50 years.
Density
For Rockwool Light Butts Scandic slabs, the density is 37 kg / m3.This is an indicator of a universal insulation that can be used in various areas that are not subject to high stress. Medium-hard fiber boards are the best option for soundproofing rooms. They are characterized by low thermal conductivity and minimal weight. The insulation does not load the supporting structure. Low density material is cheaper than more rigid counterparts.
Scope of use
Low density Rockwool Scandic thermal insulation is intended for private construction. It is used in the construction of houses, garages, outbuildings, baths and saunas. Elastic plates can be installed in various parts of the structure:
- frame walls;
- external insulation for finishing with siding;
- attic and interfloor floors;
- pitched roof.
The scope includes only non-loadable structures. This feature is associated with the low density of the material. Low water absorption and fire resistance allow the use of plates for thermal insulation of baths. The material is placed in the frame of the partitions, covered with a foil-clad vapor barrier. The increased humidity in the bath has a negative effect on the condition of the insulation. The use of non-combustible basalt wool increases fire safety. When installing mineral wool, you must use personal protective equipment.
Thermal insulation of buildings with Rockwool Scandic slabs reduces heating costs and speeds up work processes. The materials are easy to install, reliable and durable.
