Autex Polyester Underfloor Insulation

The Safest and Most Effective Insulation for Melbourne Floors.

Are you sick of your unbearably cold floors? Poorly insulated floors allow your expensive heating to escape in the colder months and leave your home unprotected from unwanted heat gain in summer, costing you a fortune on your energy bills.

Reduce heat loss by up to 20% and lower your energy cost by installing polyester underfloor insulation! It’s the safest and most effective insulation material that lasts for the lifetime of your home.

An insulation's thermal effectiveness is measured in R value; the higher the R value, the better the insulation. An uninsulated floor rates R 0.7.

The addition of carpet and a good quality underlay will improve this rating to R 1.0. ecoMaster's polyester underfloor insulation is rated at R 2.5 which achieves an overall rating of R 3.2 (without carpet) or R 3.5 (with carpet).

PLEASE NOTE: A significant price rise has been implemented since 1st November 2018 which applies to all product orders after the said date. Products held in the factory now incurs a warehousing fee.


Polyester is the best underfloor insulation material for Australian homes. Make your home cosy from the ground up with the most effective thermal efficiency solution!

Regardless of which type of subfloor type you have, we recommend installing this high-quality insulation. Polyester insulation is manufactured with exceptional standards, making it the most effective product for insulating under timber floorboards.

Specially manufactured in rolls, this insulation requires fewer joins and is easier to install than ordinary insulation batts. With the robust nature of polyester, it doesn’t lose its shape over time, ensuring long-term comfort.

Only polyester's strong, heat-bonded fibers can be secured with staples long term.
