REFLECTIVE VAPOUR BARRIER Sd > 1500 m

BARRIER ALU NET SD1500

BARRIER ALU 1500 is the aluminised vapour barrier characterised by an extraordinary Sd value.

It consists of an aluminium layer, a polyethylene film and a reinforcement grid, it is designed for application on the inner side of the building envelope of timber structures.

BARRIER ALU 1500, THE VAPOUR BARRIER FOR MOISTURE-LADEN ENVIRONMENTS

The BARRIER ALU 1500 vapour barrier membrane strongly limits the passage of water vapour from the hot to the cold side of timber structures, thus protecting them from the problems of interstitial condensation that can undermine the longevity of the structure.

The aluminised surface reflects heat by up to 70% when coupled with a ventilation chamber. Ideal for vapour flow control in very humid environments such as wellness centres, indoor swimming pools and industrial laundries, in order to safeguard stratigraphy.

Indicazioni di posa per: TETTO

BARRIER ALU NET SD1500 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 217.If there is an integrated double adhesive strip, it can replace the correct air and water sealing.

Indicazioni di posa per: PARETE

BARRIER ALU NET SD1500 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 217 or in the case of rough surfaces (such as rough OSB) FLEXI BAND, PRIMER SPAY, PRIMER .
