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.
Description
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.

Description
The application surface must be dry, free of dust and grease. Surface elements must be removed so that the membrane is not damaged during application.
The combination of aluminium cladding and glass fibre reinforcement ensures high mechanical performance that remains unchanged over time.
Recommended use: This product is intended for installation on the interior side of the building envelope and is guaranteed to withstand only indirect UV exposure for a maximum duration of 2 weeks.
The reflectivity of the membrane improves the energy performance of the construction panels: reflecting heat inwards up to 95% it increases thermal resistance.
Installation: Unroll the membrane and seal using tape such as: FLEXY BAND, SPEEDY BAND or EASY BAND.
Installation in compliance with the A2-s1, d0 value: Unroll the membrane and seal using tape with fire resistance characteristics similar to those of the membrane.
Ensure that the overlap between the membranes is at least 15 cm to achieve an optimal seal.
To ensure correct and professional installation, the use of a nail sealing point is required.
Further details regarding installation can be found in the specific instructions provided by the supplier.
