The STIFERITE know-how, gained thanks to the collaboration with expert Italian and European fitters, has enabled the development of a specific product for exterior insulation applications: STIFERITE Class SK

The use of the Class SK STIFERITE exterior insulation system allows:

• limiting the thickness of the insulating material necessary to obtain theimposed thermal resistance
• limiting the weight of the insulating layer
• reducing the costs for accessories and finishing materials (tiles, profiles, thresholds, etc.)
• ensuring the durability of the entire system and of the insulation, mechanical and dimensional stability performances
• obtaining good reaction-to-fire performances of the whole system, (from Bs1d0, the best class for organic materials, to Bs2d0 according to the adopted system components
• guaranteeing an excellent resistance to thermal shock and to the high temperatures given by the direct summer sun
• using a smaller amount of resources thereby helping to limit the environmental impact of buildings.

As an example, we list below the reductions obtainable by comparing it with an insulating material having thermal conductivity 0.04 W/mK and a density of 90 kg/m3.

Let’s hypothesise an intervention on a single-layer 25 cm wall with the goal of obtaining a transmittance equal to 0,28 W/m2K.
