E-therm Thermal Insulation

E-therm is a “3 in 1″ reflective foil insulation solution replacing traditional foil sarking, bulk fibre, and acoustic noise insulation with one easy product. With innovative and superior foam technology incorporated in the product, E-therm will also achieve the “thermal break” requirement set by the Building Code of Australia, J Section, when used on buildings with steel framework. E-therm has also been successfully tested and meets all Green Star low VOC Compliance requirements.

E-therm Reflective Foil Insulation is a thin insulation that works by combining closed cell airspace with highly reflective surfaces. It can be used in Domestic, Commercial and Horticultural building applications. E-therm is made using quality materials, and incorporates a bimetallic highly reflective aluminum film that sandwiches a low conductive layer of low density closed cell polyethylene foam. This foam has a very low rate of thermal conductivity, effectively reducing the amount of heat transmission into the building. E-therm also acts as a vapor barrier reducing the passage of moisture and dust particles into the roof and wall cavities.
