The perfect solution for insulation
Calcium silicate boards are the perfect solution for multiple insulation
The safest solution for multiple insulation, are the calcium silicate boards.
These boards have a special composition in terms of physical structure (high content of pores) and chemical structure – the plates have alkaline properties.
These boards are lightweight plane elements, produced with continuous process technology, from a homogeneous blend of calcium silicate and cellulose fibers. They can be used for interior cladding in buildings, in spaces affected by excess moisture, mould.
They have high porosity (over 80% open cells) and a low resistance to water vapor diffusion (μ between 4.9 and 9.5) corresponding to the class “practically permeable” according to norm: DIN 52615: 2005.
Due to the high percentage of open pores, the boards have absorbent properties, so that they accumulate excess moisture from the support, eliminating it as vapor to the air in the rooms. They can take up twice the volume of water compared to their own volume.
These boards are installed with special adhesives (type anti-condensation), directly on the mineral supports with excess moisture: brickwork, concrete or reinforced concrete, etc.
The low thermal conductivity of the material (about 0.052 W/m²K) provides the boards therm-insulating properties. They have dimensional stability against thermal and humidity variations.
Dry renderings made with these boards can be finished by applying an equalizing plaster layer with the same anti-condensation material used as an adhesive and coated with silicate-based products which are permeable to water vapor.
Fields of use: walls with excessive mould and moisture of reinforced concrete housing blocks, the inner isolation of any type of building, renovation of historical buildings, interior thermal insulation and refurbishment of moisture damaged walls.
Besides the special composition of these boards, the drying effect is ensured by the alkaline properties of the chemical structure.
In the case of buildings where, -for reasons of historical monument protection or aesthetic considerations-, it is not allowed to apply external thermal insulation layers -or by buildings with excessive moisture walls, the boards can be applied as internal insulation, improving the thermal resistance of the walls and ensuring drying of the walls -on which they were applied.
It is very important, that after the application of the boards, the room is provided with natural or forced ventilation, that the humid air is permanently discharged until the walls are dried.
In case of thermal and waterproof insulation of internal walls, full renovation of the walls with excessive moisture and mould, with calcium silicate boards is the super-efficient solution!
