GUTEX is considered a pioneer of ecological insulation in Europe.

Wood that comes from sustainably managed forests in the immediate vicinity of the GUTEX factory. While nothing has changed in the origin of the raw material, the products are continuously optimised in terms of building physics and processing technology. Today GUTEX offers mature insulation solutions for roofs, facades, and extensions. They convince through sustainable quality, healthy room climate and energy efficiency. This is also confirmed by the recognised residential health quality label natureplus and the European product quality label KEYMARK as well as the EMAS certification for exemplary environmental management and the sustainability certificate PEFC. .
