Welcome to the all-new Thermacell website. It has more information than ever before, and of course all-new videos about the system, too. However, we ask for your patience as, although we have covered a huge amount of information here, there is still much more to come.

Be sure to check back for new information that’s still on the way, and if you can’t find the information you’re looking for, then simply contact us at our Victorian office and we will be sure to answer any of your queries.

ICF blocks made on the Thermacell principle have been used in building construction in Europe since 1932, where the first home was built in the Bavarian Alps where it still stands today.

The system, known in Germany as Isorast, was brought to Australia in 1980 and patented here. In the ensuing four decades many dwellings and other agricultural and commercial buildings up to seven storeys high have been built.

In 1984, Geoff and Joan Bennett purchased the local manufacturing rights to the Isorast system, and established Thermacell in Victoria. That started them on the long journey of promoting this unique ICF building system throughout Victoria, and then across Australia. Trying to get a different building system accepted in a very conservative building industry was a long battle, but because of their persistence many hundreds of homes, agricultural buildings, commercial buildings, underground homes, multi-storey buildings, swimming pools & retaining walls, and many other structures have been produced.

Thermacell has stood the test of time here in Australia.
