3D MATS FOR METAL ROOFS

TRASPIR METAL

Installed on a continuous support, the TRASPIR METAL three-dimensional mat for soundproofing facilitates the micro-ventilation of metal roofs, stopping them from corroding and thus increasing their durability.

The TRASPIR METAL range is complete: it is available with lower breathable impermeable membrane and with upper TNT draining layer.

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.
