The benefits of underfloor insulation

Does your home have timber flooring? If so, you could be losing up to 20% of your heating through your flooring if you do not have underfloor insulation. While carpet and underlay help to provide a degree of insulation, carpet alone doesn’t effectively seal your home and solve the problem.

The most effective and efficient way to maximise heat retention in your home is to create an effective thermal barrier through underfloor insulation. Underfloor insulation allows you to create a warm, dry and healthy home while reducing your energy footprint through a reduction in greenhouse gas emissions.

Available in a range of sizes, light in weight, and quick and easy to install, the Expol Underfloor Insulation system is an easy DIY project and a smart way to start saving money on your energy bills while adding value to your home.

      I have just installed Expol under my floor as we live in the country and my wife has Chronic Lung Disease. We are very pleased with the result as she can now walk around the floor without feeling cold. Another side effect is that the floor has stopped creaking!

      I'm very happy with the end result, we didn't use our heater half as much after the Expol insulation was installed and our baby boy crawling around the floor probably noticed the most difference, without getting such cold hands and knees. We are very happy with the product and service provided.


      We are very happy with the installation of Expol, even though it's only been a bit over a week since it was installed we have noticed a big difference & find we are turning the air conditioner off about 1 hour before going to bed because the lounge room is so warm, which we have never done before. I would have no hesitation in recommending your product & your service, which was excellent.
