Dowell has been creating innovative window and door solutions in Australia since 1860 and in 2012 was awarded the HIA GreenSmart Product award.
According to HIA judges, “ThermaLine windows are a versatile, high-performing and cost-effective aluminium window range. The ThermaLine frame has a similar thermal performance to the installed glass and with Uw values as low as 1.7, is rated the best in its class. The low Uw values benefit homes with large amounts of glazing, allowing them to achieve 6 stars or better in thermal efficiency. A great cost-effective solution for energy savings to the residential housing market.” dowell.com.au
