Therma is an insulation board made of PIR rigid insulation foam. A synthetic resin with an almost fully closed cell structure. Because of the dense structure, high insulation values can be achieved with minimal thicknesses. PIR also has a high compressive strength and is therefore extremely suitable for roof applications. Because of the light weight, Therma is easy-to-install. Therma is applicable for multiple construction element like roofs, walls and floors in both housing and utility building types.
