Heat Loss

As much as 49% of the heat lost during winter and as much as 87% of the heat gained during summer can come from the windows*.

In Melbourne around 75% of household energy usage is for heating, while around 90% of energy is used for cooling homes in Brisbane. The emphasis on selecting the right product to reduce heat loss in a colder climate and reduce heat gain in a hotter climate should be an important decision to achieve greater comfort and energy efficiency. Choosing the right product and glazing option will help.

The award winning Dowell ThermaLine™ product range with its custom glazing options provides outstanding comfort, noise reduction and energy efficiency, all factors that are highly desired when constructing a new home or renovating an old one.
