Crypton is engineered with materials that are safe for the environment and all of our chemistry is Cradle to Cradle certified by MBDC. Crypton is free of PVC, rubber, VOCs and halogenated flame retardants. Our Super Fabrics are produced using green manufacturing practices. Waste products are recycled, and we are constantly purchasing new energy-efficient machinery to reduce consumption of materials, water and energy. Crypton Super Fabrics for your home are produced using renewable energy sources: solar, wind and hydro, and we have partnered with Sterling Planet to invest in new wind and solar power installations.
