Modern building design places significant emphasis on correct window selection and placement with an aim to reduce demand for artificial light and climate control, resulting in lower energy use and decreased carbon emissions.
Up to 40% of energy consumed in a home for cooling or heating is lost through windows; improving the thermal performance of windows will, therefore, reduce energy costs and greenhouse gas emissions.
WERS or the Window Energy Rating System rates the energy impact of windows in housing anywhere in Australia. Windows and doors are rated as a whole unit, complete with glass and frame. High performance glazing is a waste when used with a leaky frame that creates a draft. It is also important to seal the spaces between windows and wall during installation.
The U-value of a window is an important factor: The lower the U-value, the better the window’s thermal performance will be.
Paarhammer windows have U-values starting at a low 0.8 for windows and doors. In terms of energy consumption, these windows and doors can save up to 84% in cooling and 76% in heating.
Timber is an ideal material for doors and windows from a sustainability perspective as the material is light, strong, natural and renewable, and also meets thermal, acoustic and design requirements.
Paarhammer windows are made from sustainable, renewable materials: Victorian Ash is a plantation grown timber in Gippsland while Manilkara Bidentata (mainly used for bushfire areas) is FSC certified. Paarhammer has been FSC Chain-of-Custody certified for many years.
End users of Paarhammer Windows & Doors can save on energy costs and create a more comfortable living environment in the home or office while reducing carbon emissions.
