Frequently Asked Questions
When should I install wall insulation in an existing home?
The best time to install wall insulation is during a renovation or extension—especially if you’re removing or replacing wall linings. If the wall cavity is exposed, it’s the ideal opportunity to insulate properly before closing it back up.
What type of insulation should I use in my walls?
We recommend Polymax polyester batts—they’re safe to handle, don’t itch, and won’t slump over time. They provide excellent thermal and acoustic performance and are a long-term solution that adds comfort and value to your home.
What if I’m not removing wall linings—can I still add wall insulation?
Yes! If you're not renovating but still want to insulate, we can refer you to trusted retrofit specialists who install insulation into existing walls using a method that doesn’t require removing plaster or cladding. Please contact us for a referral.
Is wall insulation really that important if I already have ceiling and underfloor insulation?
Definitely. Walls can account for up to 25% of heat loss or gain in a home. Adding wall insulation helps complete the home’s thermal envelope—so your heating and cooling work more efficiently, and your home stays comfortable all year round.
Can I install wall insulation myself during a renovation?
Yes—if the wall cavity is accessible, it’s totally possible to DIY wall insulation, especially with easy-to-handle products like Polymax. Just make sure you follow safety and spacing guidelines to get the best result.
