Foilboard insulation is a rigid, high-performance solution that ticks all the boxes for contractors needing speed, compliance, and thermal control. With a reflective foil layer on each face, it’s designed to reduce radiant heat transfer while providing a clean, consistent finish that doesn’t slump or degrade over time. That means fewer call-backs and better long-term results for your clients.

At Insulation Essentials, we supply foilboard in a wide range of thicknesses—from 10 mm right through to 50 mm—ideal for everything from wall cavities to underfloor installs. Our products are stocked locally in Melbourne, so you can get what you need fast, without delays holding up your build.
