Walls construction
Our ecological wood-based insulation meets high standards, achieving thermal capacity of 2100 J/(kg*K), low thermal conductivity (λD= 0,038-0,042 W/m*K) and high air flow resistance (50 - 100 (kPa*s)/m³).
All these parameters ensure a constant temperature inside, almost independent of external conditions.
The ability to absorb and deliver atmospheric moisture (Sd=0,06-0,72 m) allows the boards to “breathe” preserving their technical characteristics and providing optimal humidity and preventing mould and fungus formation on walls and ceiling. The air at home will never be too dry or too humid, which ensures comfortable feeling.
High density (110-200 kg/m³) and homogeneity protect from impact and airborne noises inside the house (Rw= 23-27 dB) and high porosity allows absorbing noise outside (αw=0,60-0,95). The house will always be quiet, which will save on additional sound insulation.
The presence of not only natural wood (pine) but also eco-friendly binding components (polyurethane-based resin) in the composition provides absolute safety for the human and the environment, which is important for highly allergic individuals. Due to the loose structure and the lack of nutrients the boards do not spark rodents’ and insects’ interest.
Inert burning by means of carbonization doesn’t spread fire (fire resistance “E” (European class according to EN 13501-1)). The natural composition guarantees the absence of toxic products when burning.
The convenient format of the boards (straight edge/tonguing and grooving/step) and the environmental friendliness of the material allow manual assembling without the use of protective means. The boards closely join together and when necessary are easily cut to the required size.
