In Europe Thermacell's equivalent is ISORAST, which means ‘interlocking insulation’.
This product, invented in Germany about 57 years ago, has been used in literally tens of thousands of homes and structures, and is still very much in use over most of Europe for building homes, cellars, factories, multi-storey buildings, swimming pools, spas, fences and retaining walls.

Thermacell’s own ICF wall systems were derived from Isorast, which can be regarded as the world’s best ICF engineering. The latest Thermacell Australian innovated and engineered ICF technology was designed over 26 years ago with owner-builders (DIYs) in mind, primarily because of the simplicity of construction - even a child can build with it!

It’s believed professional builders are now using Thermacell more than any other ICF system because of Thermacell's simplicity, cost, speed, strength, building savings and insulation properties.

With basic skills, care and common-sense, owner-builders can successfully build walls with Thermacell, achieving strong engineering integrity and lifetime energy savings.
