What customers say

Great product
Don’t waste your money or time with the stuff from Bunnings. The ecoMaster poly floor made a huge difference to the temperature inside the house and was super easy to install.

You can Feel the Difference in Floor Temperature Under Your Feet!
My home’s subfloor is low enough that I couldn’t find any tradesperson to insulate it, so decided to DIY it. Needless to say, it’s a miserable process, but that’s got nothing to do with this polyester insulation. In fact, if the insulation wasn’t so good I would have given up. It’s positively pleasant to work with, tears only in one direction, just as advertised, and isn’t irritating whatsoever. The scraps make perfect pillows to lie on while working in the subfloor. Haven’t finished the whole house but under bare feet, I can already feel the difference in floor temperature in the insulated areas.

The difference is extraordinary
The difference ecoMaster’s underfloor insulation has made to our Macedon Ranges residence has been extraordinary. We remained snug in winter while reducing our fuel bills and cool in summer needing neither AC or fans when the outside temperature reached 37 degrees. A very good purchase from an efficient, polite and knowledgeable company.
