REFLECTIVE AIR VAPOUR BARRIER FIRE REACTION CLASS A2-S1,D0
BARRIER ALU FIRE A2 SD2500
BARRIER ALU FIRE A2 SD2500 is a reflective vapour barrier which has been tested according to EN 13501-1 and classified as a non-combustible material (A2-s1, d0) for reaction to fire. Its reflectivity improves the energy performance of the construction panels: reflecting heat inwards up to 95% it increases thermal resistance.
BARRIER ALU FIRE A2 SD2500, the non-combustible and resistant vapour barrier.
Thanks to the special aluminium film, BARRIER ALU FIRE A2 SD2500 is extremely UV-stable, ageing-resistant and non-combustible, offering protection even on the construction site. As it is non-combustible, it can also be used in combination with photovoltaic systems or at electrical voltage points.
The combination of aluminium cladding and glass fibre reinforcement ensures high mechanical performance that remains unchanged over time.

Indicazioni di posa per: TETTO
BARRIER ALU FIRE A2 SD2500 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 218.If there is an integrated double adhesive strip, it can replace the correct air and water sealing.
Indicazioni di posa per: PARETE
BARRIER ALU FIRE A2 SD2500 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 218 or in the case of rough surfaces (such as rough OSB) FLEXI BAND, PRIMER SPAY, PRIMER .
