Types of Insulation We Use
​
We work with trusted and proven products to suit different roof types and customer needs:
Sisalation
A reflective foil insulation used under metal roofing to reduce radiant heat. It acts as a vapour barrier and provides extra protection from moisture.
Anticon Blanket – 55mm or 85mm
Combines reflective foil with glass wool blanket to reduce heat transfer, absorb sound, and prevent condensation.
It's also fire-resistant, making it safe and reliable option for Australian homes.
• 55mm Anticon is great for most residential roofing jobs
• 85mm Anticon offers higher thermal and acoustic performance, ideal for larger homes or hotter regions
SL Insulation
