Polyester insulation is the best wall insulation for Australian homes. It is a high-performing, low-allergenic, moisture- and rodent-resistant insulation solution. It maintains its loft for the lifetime of your home.

The addition of wall insulation batts will allow you to take control of your energy consumption as they prevent your winter heating from escaping and the summer heat from penetrating your living spaces. The result? A more comfortable home and significantly lower heating and cooling costs!

Help keep your indoor temperature as you like it from all directions along with reducing outside noise from entering your home! 

Fitting polyester insulation in your walls increases the barrier between the outside temperature and internal temperature. This product is specially designed for the thermal insulation of timber and steel-framed buildings. 

You can use it any time you find your walls are not keeping the temperature to your standards. They come as batts already cut to fit standard timber framing.

    How To

    Tools You Will Need For Installation:

    • Knife/blade
    • Clothes you don't mind getting dirty

    Polymax wall batts are easy to install. Just follow these "how to" videos: 



    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.


    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.


    Q: What is the product warranty for Polymax?
    A: Polymax carries a product warranty of 70 years, but can be highly effective for much longer than that. We have not yet seen a 'failed' polyester product. It is incredibly robust and is not damaged by the elements that would generally damage other types of insulation. 

    Q: What is the installation warranty for Polymax?
    A: As Polymax is a DIY product there is no warranty on installation.  

    To get the best value for your investment, please, PLEASE watch the installation videos before you proceed.  

    Q: How do I register for my 70 year warranty? 
    A: Great question!   Register your purchase here and remember to retain your tax invoice.  Attach it to your warranty when you download it after registration.  File it with your important documents.  The warranty will be transferable to new owners of your home - so make sure they know about the warranty and provide them with the documentation to support it. 

    If you have any questions, contact the ecoMaster team.  We are all ex-installers and have done this work thousands of times before.  We are here to help you.

    Q: What do I do if I have a problem with this product?  
    A: Refer to our Returns / Refunds page [Learn More].  Our Research and Development team will be keenly interested to learn of any product failure and will want images and samples of the product (if possible) so they can determine what the cause of failure was.
