Kingspan Aircell Permicav XV is the go-to choice for low-rise builds where you need high performance without the moisture risks of traditional batts. It acts as a breathable skin for the building, keeping the structure dry and the interior comfortable. It’s a faster, cleaner way to insulate walls while ensuring the frame stays dry for the life of the building.
Features:
- Micro-perforations let the wall “breathe,” preventing mold and frame rot.
- Keeps the wall space open, making life easier for sparkies and plumbers.
- Replaces multiple layers by acting as insulation, a vapor barrier, and a foil shield.
- The foam won’t soak up water or sag, even if it gets wet during construction.
- 100% fiber-free, so it’s clean to cut and fast to install without the irritation.
Applications:
- Install in the cavity of double-brick walls to provide a thermal shield while letting the wall “breathe.”
- Fix behind lightweight cladding or timber weatherboards to manage moisture and prevent mold buildup.
- Use in masonry veneer constructions to block radiant heat from entering through the brickwork.
- Apply in residential or commercial wall systems that require a Class 3 or 4 vapor permeable membrane.
- Wrap around the exterior of timber or steel-framed walls where high breathability is needed to protect the structure from dampness.
