NIBE Rates EPDM as a Class 1A Product

The independent Netherlands Institute for Building Biology and Ecology (NIBE) evaluates the environmental impact of building products, from production to recycling.

EPDM received a rating from NIBE as one of the best products for use on flat roofs.

It is based on a procedure developed by the Center for Environmental Science in Leiden. It evaluates all environmental impacts and hidden environmental costs over the complete product life cycle.

Seven commercially available roof sealants were examined for ecological and health aspects. Taking into account the long service life of at least 50 years, EPDM was classified in the best product class 1A.
