TRASPIR METAL: the only solution of its kind tested on site from the point of view of sound insulation against rain beating on the roof.
Highly breathable membrane paired with a 3D mat and protective felt.
The top felt prevents impurities from getting into the mat and improves resistance to treading, preventing water stagnation.
The effectiveness of TRASPIR METAL as a solution for sound insulation against the noise from heavy rain is certified by the Giordano Institute.
