Frequently Asked Questions
Will underfloor insulation make a noticeable difference?
Yes—especially in homes with timber floors. Without underfloor insulation, up to 20% of your heating and cooling can be lost through the floor. You’ll likely notice warmer floors in winter, reduced draughts, and better temperature stability throughout your home - making it a smart, long-term investment for both comfort and cost savings. Many people also report needing their heater or air con less often after installation.
Is it safe and environmentally friendly?
If you’re using Polymax, yes! It’s made from 100% polyester (like a doona), contains no nasty chemicals, and won’t irritate your skin or lungs. It’s also non-toxic, low allergen, and fully recyclable—so it’s better for you and the planet. And it carries a 70 year warranty.
What is underfloor insulation made from?
Our most popular underfloor insulation, Polymax, is made from 100% thermally bonded polyester fibres—the same safe, soft material used in quilts and pillows. It contains no glass wool, formaldehyde, or itchy fibres, making it safe to touch, low allergen, and ideal for DIY installs. It’s also fully recyclable and proudly made in Australia.
Can I install it myself, or do I need a professional?
If you're reasonably handy, you can absolutely DIY underfloor insulation! Polymax is safe and itch-free to handle. We provide clear, step-by-step guides to help you through it. That said, if your floor is very low to the ground or access is tricky, you may prefer to hire a pro. Please contact us for a referral to a trusted installer in your area.
