What is the essence of complex house insulation?
Our ancestors tried to save heat in their homes by increasing the capacity of the building's box, and therefore castles with a 1.5-meter-thick wall were born. Modern construction has flatly refused such prodigal methods of protection, preferring to approach the problem from a scientific point of view.
It is known that heat "travels" in space in three ways:
- Convection, when warm air circling in a room and simultaneously warms everything in its path.
- Conduction, when a hot object, in contact with a cold one, gives it some of its energy.
- Radiation, when a heat wave penetrates through any obstacles, simultaneously distributing its energy "reserves".
Classical natural and polymer insulators perfectly block heat in the first and second cases, but to stop the invisible "fugitive", you need a special mirror insulator reflecting radiation in the infrared spectrum. Ideal for these purposes is a polished aluminum foil.
As a result, the improved protective "puff" should look like this:
Interior finish + foil + insulation + hydraulic barrier + exterior trim
To simplify the installation work on the installation of this complex system, mineral wool foil was developed, including two ready-made blocks of this"Puff cake".
The foamed mineral wool is the strongest insulator of the "2 in 1" class
. It is not by chance that these two insulators got into a pair. Each of them is the leader in its field:
- Aluminum foil not only reflects up to 97% of infrared heat radiation, but also does not let steam and gas pass, it is neutral and environmentally friendly material, easily takes any shape,corrosion.
- Mineral wool is a fire-resistant insulator with excellent heat conductivity( 0,038 - 0,045 W / K × m).It works equally well, as well as at low temperatures( up to -200 ° С), and at high temperatures( up to + 1000 ° С).Stone material is not afraid of chemical and biological attack, it has a decent index of strength( it keeps a "blow" up to 80 kPa).
Mineral wool with foil - beneficial companions, which effectively strengthen each other. Reflecting "mirror" - a fragile material, and strong in nature mineral wool plays for it the role of a fastening base. Conversely, cotton wool insulation suffers from hydrophobia, and a vapor-proof mirror film protects it from harmful moisture.
Minvata with foil is available in rolls, and in slabs, mats, and cylinders, so when finishing workers it is not necessary to greatly alter expensive consumables.
Where is the most advantageous to use minvat with foil?
A mineral wool insulator is the most popular insulator widely used for internal and external protection of a house, but a foil-type material is rarely used for this purpose. But it took its narrow niche, where it brings the maximum benefit from its unique technical properties. This - the insulation of baths, saunas and other structures, structures with extreme temperature conditions.
Foamed mineral wool speeds up and facilitates the warming of the walls of the steam room, the builder does not have to worry about carefully covering all surfaces with a thin film of foil, which is very finicky in work. Finishing works are reduced to fastening on special hooks of mats of a material and care of dense joining of the next elements.
Another important direction of the "reign" of mineral wool with foil is the warming of hot water and oil pipelines. Here, the material contributes to a significant saving of energy resources, excellently endures extreme operating conditions.
