Airtightness and vapour control coating

NSAI certified:

• for the permanent airtightness and vapour control of buildings/building elements by brush, roll or spray applying this product on building connections or walls depending on specifications and design.
• to resist the ingress of radon into the building.

• Suitable substrates include concrete, masonry, bricks, blocks, plaster/render, engineered wooden boards, OSB wood, multiply timber, plasterboards, fibre cement boards, calcium silicate boards, tapes, membranes,
  aluminium, spray foam insulation, insulation boards (PUR, PIR, polystyrene, Rockwool®), steel and PVC.

BLOWERPROOF® products have been assessed by NSAI for use in the following applications:

• Applied to the external side of the internal wall (prior to the installation of insulation panels/ façade system) to act as an airtightness and vapour control layer.
• Applied on the internal side of the Internal wall, to act as an airtightness and vapour control layer, where the insulation is applied to the outer side of that wall i.e. when the cavity is filled with either insulation beads, rigid boards, etc (Cavity wall).
• Applied on the internal side of the Internal wall, to act as an airtightness and vapour control layer, where the insulation is applied to the outer side of that wall (Cavity wall), and whereby the internal side is finished with an insulation board.
• Applied on the internal side of the Internal wall, whereby BLOWERPROOF® is applied to the insulation or the concrete block wall (on the warm side of the insulation), to act as an airtightness and vapour control layer.
• Applied on floor to wall connections, wall to roof connections and window frame to wall connections, to be finished with plaster (airtight), at required thickness to achieve airtightness.
• Applied around penetrations and abutments e.g. wires and pipes.
• Applied direct over polyurethane spray foam or rigid insulation boards where vapour control is required.
• Applied to floors or walls as part of a radon protection system.
• Applied to plaster board to provide an airtight or vapour control function.

BLOWERPROOF® LIQUID is spray and/or roll applied on the inside of brick walls taking into consideration the general guidelines for applying this product. Multiple passes may be required to achieve the required minimum wet thickness.

Typical building systems with BLOWERPROOF® applied on walls:

• Applied on the internal side of the Internal wall, to act as an airtightness and vapour control layer, where the insulation is applied to the outer side of that wall i.e. when the cavity is filled with either insulation beads, rigid boards, etc (Cavity wall). After curing, different types of finishes are possible such as plasterboards be fixed onto the BLOWERPROOF® layer by standard dot & dab techniques using PRIMER 52.
• Applied on the internal side of the Internal wall, to act as an airtightness and vapour control layer, where the insulation is applied to the outer side of that wall (Cavity wall), and whereby the internal side is finished with an insulation board.

• Fill gaps greater than 2mm with non-shrink polyurethane foam. Do the same for joints, pipes, cables, ducting, joists and all other penetrations.
  
• Apply BLOWERPROOF LIQUID in two coats ensuring that the first coat is fully dry before applying the second coat.

BLOWERPROOF® has been assessed for used on these insluation materials: PUR, PIR, polystyrene, Rockwool®
