VAPOUR CONTROL MEMBRANE

VAPOR IN 120

VAPOR IN 120 is a vapour control membrane for controlling the passage of water vapour in timber structures and houses.

It consists of a functional film and a polypropylene reinforcement and is designed for application on the inside of timber roofs and walls.

VAPOR IN 120 VAPOUR CONTROL MEMBRANE: FOR AN AIR-TIGHT ENVELOPE

The VAPOR IN 120 vapour control membrane regulates the passage of moisture into the timber structure, preventing the formation of interstitial condensation within the insulation package and increasing the durability of the structure.

It is transparent, making it easy to install when insulating from the inside or for easy installation between beams. It is also available in a 3-metre version for even faster installation times.

Indicazioni di posa per: PARETE

VAPOR IN 120 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 ALU BAND, SEAL BAND, EASY BAND, SPEEDY BAND, SOLID BAND, FLEXY BAND, SMART BAND, PLASTER BAND, DOUBLE BAND, SUPRA BAND, BUTYL BAND, MEMBRANE GLUE, SUPERB GLUE, ECO GLUE, FIRE SEALING, FIRE FOAM, FIRE STRIPE, FRONT BAND UV 219 or in the case of rough surfaces (such as rough OSB) FLEXI BAND, PRIMER SPAY, PRIMER .

Indicazioni di posa per: TETTO

VAPOR IN 120 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 ALU BAND, SEAL BAND, EASY BAND, SPEEDY BAND, SOLID BAND, FLEXY BAND, SMART BAND, PLASTER BAND, DOUBLE BAND, SUPRA BAND, BUTYL BAND, MEMBRANE GLUE, SUPERB GLUE, ECO GLUE, FIRE SEALING, FIRE FOAM, FIRE STRIPE, FRONT BAND UV 219.If there is an integrated double adhesive strip, it can replace the correct air and water sealing.
