INDOOR AIR COMFORT GOLD

Higher level "Indoor Air Comfort GOLD - certified product" shows additional compliance of product emissions with the criteria of many of the voluntary specifications issued by most relevant ecolabels and similar specifications in the EU and requirements for sustainable building certifications. Therefore certified products are those with the best-in-class low emissions, thus good for indoor air quality.

ENVIRONMENTAL PRODUCT DECLARATION (EPD)

EPD are independently verified and registered documents that communicate transparent and comparable information about the life-cycle environmental impact of products.

BIOSOLUBLE WOOL

The mineral wool used in our products is biosoluble and therefore not a health hazard. The two quality labels RAL and EUCEB ensure the biosolubility of the wool through regular testing.
