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.

Specifications
Supply and installation of three-dimensional mats for metal roofs, type TRASPIR METAL
CE marking according to : EN 13859-1
Indicazioni di posa per: PARETE
TRASPIR METAL is laid parallel to the dock beam or the floor if laid on a wall. The second layer must be overlapped by at least 15 centimetres. Each layer must be fixed to the substrate with a mechanical fastener. (ex: HAMMER STAPLER, HAND STAPLER o PNEU STAPLER). It is also advisable to overlap the sheets by at least 30 centimetres at the butt joints. In order to achieve correct air and water sealing, we recommend the use of EASY BAND, SPEEDY BAND, FLEXI BAND, FLEXI BAND UV, SOLID BAND, PLASTER BAND, SMART BAND, FACADE BAND UV, FRONT BAND UV, FRONT BAND UV 210, DOUBLE BAND, SUPRA BAND, BUTYL BAND, OUTSIDE GLUE, FIRE SEALING, FIRE STRIPE or in the case of rough surfaces (such as rough OSB) FLEXI BAND, PRIMER SPAY, PRIMER .
Indicazioni di posa per: TETTO
TRASPIR METAL is placed parallel to the eaves line, starting from the lower edge of the roof. The second layer must be overlapped by at least 10-20 centimetres to the previous one (depending on the slope of the roof), as indicated on the layout according to UNI 11470:2013. The sheet must be applied on a continuous support with a mechanical fastening device. (ex: HAMMER STAPLER, HAND STAPLER o PNEU STAPLER). Once at the top of the roof, it is advisable for the membrane to protrude beyond the ridge line by at least 30 centimetres to ensure a perfect overlap with the strips of sheet that will overlap on the other side of the roof. It is also recommended that the sheets overlap by at least 30 cm even at the end joints. To achieve correct air and water sealing, we recommend the use of EASY BAND, SPEEDY BAND, FLEXI BAND, FLEXI BAND UV, SOLID BAND, PLASTER BAND, SMART BAND, FACADE BAND UV, FRONT BAND UV, FRONT BAND UV 210, DOUBLE BAND, SUPRA BAND, BUTYL BAND, OUTSIDE GLUE, FIRE SEALING, FIRE STRIPE.If there is an integrated double adhesive strip, it can replace the correct air and water sealing.
