Delivery
Q: How will my order be delivered?
A: We will contact you to advise when your order can be manufactured and delivered to your home.
Q: Where can you deliver to?
A: Orders can be delivered to just about anywhere within Australia. However, the freight costs can become relatively high if you are in a regional or remote area. Please contact us with your location for a freight quote.
Consider collaborating with your neighbours to share an order as the freight price is the same whether there are a few bags or the truck is filled to capacity.
Q: Can I collect my order from the Sydney manufacturing plant?
A: Yes, you can. When your order is ready for collection, you will be advised.
Q: Can I get a return excess insulation?
A: No. All Polymax orders are "made to order" and cannot be returned. If you can excess insulation, please contact us and we will help you sell it via social media. There is a buoyant market for polyester insulation.
FAQ
Frequently asked questions
Q: Do you have a warranty for this Insulation batts?
A: The insulation product has a warranty of 50 years. You will need to retain the information displayed on the label on the outside of each pack. Namely the batch number to exercise any possible claim.
Q: How about for the product installation, do you have a warranty for it?
A: As it is a DIY product, we cannot provide an installation warranty, as the installation process is outside of our control. However, if ecoMaster provides installation, we can comfortably guarantee that our installation process will last 10 years provided that there will be no external force applied - just as other trades or the impact of wombats.

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.
