E-Therm Insulation

Because E-Therm UF is a semi rigid sheeting supplied in a convenient 10 metre roll (500mm wide) pre slit to fit in between 450mm centre floor joists, it is the fastest and most convenient insulation material to use under floors. If your home is a traditional design with a timber floor mounted on stumps, with open void space below, E-Therm is the under floor insulation for you!

It works most effectively when applied in such a way as to create a sealed, reflective air space, and this is really easy to do under suspended timber floors. Sometimes pest inspectors, plumbers or electricians need to be able to remove insulation to complete their work. Unlike bulk fibre, E-Therm can be easily temporarily removed and replaced without major damage or cost.

E-Therm stops drafts and dust, is completely water resistant, will not shrink and is fibre and itch free.
