Passivhaus Institute in Darmstadt recently found that SWISSPACER‘s aluminium and warm edge spacer bars save homeowners a significant amount on energy bills.
Research found that warm edge spacer bars instead of aluminium in a triple glazed window saves homeowners an average of 8.6 percent on energy bills in cool/moderate climates such as the UK and Ireland.
The Passivhaus Institute is an independent research institute which aims to dramatically reduce the need for space heating and cooling, and typically cuts energy use and CO2 emissions by a factor of 10.
The standard requires a Passivhaus to have an excellent thermal performance, exceptional airtightness and mechanical ventilation. The heating requirement in a Passivhaus is reduced to the point where a traditional heating system is no longer considered essential.
Jan Hiersemenzel, SWISSPACER Marketing Director for Europe comments: “SWISSPACER Ultimate was the first warm edge spacer bar to gain Passivhaus accreditation and is widely specified in low energy installations. The Passivhaus database of certified components lists SWISSPACER in 70% of windows, 86% of windows with fixed glazing and 97% of curtain wall systems.”
