ARBOShield Pro Class B W1 Breather Membrane is ideal for light steel frame (SFS) walling applications, making it particularly suitable for high-rise and high-risk buildings such as schools, hospitals, care homes, and residential blocks, where it helps reduce the spread of fire. It is also appropriate for modular off-site construction. The membrane’s composition limits the spread of fire across a façade, with minimal risk of smoke or burning droplets in the event of a fire. ARBOShield Pro Class B W1 Breather Membrane can be installed on any Class A rated substrate.

 

 

APPLICATION

Unroll the ARBOShield Pro Class B W1 Breather Membrane and secure it directly to the sheathing or insulation. The membrane should be fixed to the substrate using the appropriate fixings, with a maximum spacing of 600mm horizontally and 500mm vertically, using stainless steel staples. For SFS substrates, the membrane should be mechanically secured with fixings that include an EPDM type washer. All laps around perimeter edges should be sealed with ARBOShield Pro Class B High Tack adhesive tape. Vertically, the membrane must overlap by at least 150mm, with joints arranged in a staggered pattern. For horizontal laps, ensure a minimum 100mm overlap, starting from the bottom and working upwards, so the upper layer covers the lower one, protecting the substrate from water run-off.

Install fixing brackets for cladding or wall ties according to the manufacturer’s instructions, and take care at the interface between the membrane and fixing brackets. If cavity barriers are installed horizontally, the membrane should overlap the DPC tray to allow for water run-off. When ARBOShield Pro Class B W1 Breather Membrane is used as the external airtightness layer, overlaps and penetrations should be sealed using ARBOShield Pro Class B black membrane sealing tape.

The membrane is highly UV resistant, allowing for extended exposure in both summer and winter without compromising performance. Care should be taken during installation to avoid damage to the membrane. For small punctures less than 50mm, use ARBOShield Pro Class B black membrane sealing tape for repairs. For larger punctures exceeding 50mm, replace the damaged section with new membrane and seal the insertion with tape.
