Reduce energy bills with polyester ceiling insulation

According to CSR Bradford an insulated home can lose up to 42% of its heat through the ceiling in winter. During the hot summer months of December, January and Februrary an uninsulated home will quickly overheat and become uncomfortable. Most people compensate for this by turning on the air-conditioner or fan, which in turn leads to higher energy bills. With the rising cost of energy this is no longer a viable option for many Australian home-owners.

Topping up your roof

Insulation can deteriorate in quality over time meaning that it is no longer as effective as when it was first installed. You can read our blog post about topping up insulation here. The most important thing to keep in mind when purchasing insulation is that a higher R-value indicates better thermal performance. We are noticing a strong trend among DIY builders and renovators to opt for higher R-values in their walls and ceilings. Investing in Polymax Ceiling Insulation can lead to long term financial savings in addition to improved thermal comfort.

Polyester Insulation that is 100% reusable and soft to handle

Polymax Ceiling Insulation is manufactured without the use of added chemical or resin binders. No water or ozone-depleting gases are used in the manufacture of Polymax. It is soft and easy to handle making it more comfortable to install than traditional glasswool products. Bradford Polymax is 100% reusable, making it a great environmental choice. Polymax batts should fit snugly between the timber joists; leaving gaps of even 1cm can greatly reduce the effectiveness of the insulation. Polymax Insulation is available in 430mm and 580mm widths to fit 450mm and 600mm joist centres. Polyester insulation batts can be torn or cut to fit irregular joists.
