Sustainability for End Users

Careful window selection and placement is rightly viewed as a means of reducing demand for artificial light and climate control.

WERS – Window Energy Rating System - rates the energy impact of windows in housing anywhere in Australia. With up to 40% of a home’s energy for cooling or heating being lost or gained through windows, improving their thermal performance reduces energy costs and Australia’s greenhouse gas emissions.

Windows and doors are rated as a whole, meaning glass and frame together. High performance glazing is a waste if the frames leak and create a draft. Equally important is sealing the spaces between windows and wall but installation is another topic.

The lower the U-value, the better the window. U-values of Paarhammer products start from a low 0.8 for windows and doors. These windows and doors can save up to 84% in cooling and 76% in heating.

Timber is an ideal material when considering sustainable aspects as it is a material that is light, strong, natural and renewable. It meets thermal, acoustic and design requirements.

Paarhammer windows are made from a sustainable hardwood: American oak which is legally harvested and has a low environmental impact while Manilkara Bidentata (which we mainly use for bushfire areas) is FSC certified. Paarhammer has been FSC Chain-of-Custody certified for many years.
