Engineering for the future

Siplast developed our first vegetated roof system, Teranap, in the 1970s. And we haven't stopped since – from reusable insulation to bright white liquid-applied roof membranes and a granule surfacing that can help neutralize dangerous nitrogen oxides in the atmosphere – we've been designing products our partners can use to meet their environmental and sustainability goals. Supporting green building rating systems is our ongoing commitment and promise to our customers.
