Product Criteria
Design requirements
Designed to prevent air leakage and water penetration around window and door openings at framing junctions, and to keep any water that gets past the cladding, or through the joinery, from direct contact with the framing timber.
Installation requirements
- Must completely cover the joinery opening.
- The wrap is then cut on a 45 degree angle away from each corner of the opening so the flaps can be folded into the opening and secured to the interior face of the timber framing.
- The surface must be clean, dry and free from any surface contaminants such as dust and grease that may cause loss of adhesion.
- A 75mm wide x 150mm long sealing tape 'butterfly' must be installed at 45 degrees across the corner of the jamb/sill junction overlapping the corner by 3mm to create a seal at the corner of juction.
