Kingspan Aircell Permishield 70 is built to make steel-frame and lightweight cladding jobs faster and more compliant. Instead of messing around with separate layers of sarking and bulky batts, this one sheet does it all.

Features:

• Combines insulation, a thermal break, and breathable sarking into one step.
• The patented “breather holes” let internal moisture escape, preventing condensation buildup in the wall.
• Specifically engineered to provide the thermal break required for steel-framed homes.
• It is CodeMark-certified, meaning it’s a “safe bet” for BCA compliance and achieving 6-star energy ratings.
• The closed-cell foam won’t soak up water, sag, or lose its R-value if it gets wet during the build.

Applications:

• Wrap the outside of steel-framed homes to act as a thermal break while allowing the wall cavity to breathe.
• Install behind timber or vinyl cladding to prevent condensation from getting trapped against the frame.
• Use in masonry veneer or double-brick walls to provide a radiant heat shield that resists mold and moisture buildup.
• Apply to the exterior of timber-framed houses in cooler climates where “breathability” is essential to prevent wood rot.
• Fix to wall systems in high-humidity areas to ensure indoor moisture can escape through the micro-perforations.
