Tried and tested to give the best performance, Munster Joinery confirms that: “Windows with SWISSPACER warm edge spacer bars inside can achieve U-Values of 0.7 W/m2k with triple glazed sealed units and 0.5 W/m2k with quadruple glazed sealed units.”SWISSPACER ULTIMATE is the best warm edge spacer bar in the world for thermal efficiency: 80% of Passivhaus windows have SWISSPACER inside. Passivhaus is the world’s leading fabric first approach to low energy buildings.SWISSPACER is the first warm edge spacer bar to achieve Passivhaus standard and the only warm edge spacer that has been rated energy efficiency class A by the German Passivhaus Institute. SWISSPACER has also been designed to last for decades thanks to its High Tech Gas Barrier which stops gas and moisture penetration through the spacer bar. In a well-made sealed unit, it will save energy for decades.
SWISSPACER Marketing and Sales Director, Peter Appel, says: “Quadruple glazing is becoming increasingly popular in parts of Europe and in China. SWISSPACER offers the best results and is ideal for both triple and quadruple glazing because of its top thermal performance and strong, rigid structure. Triple and quadruple glazing with SWISSPACER inside provide the most energy efficiency solutions, also the production is easy and simple to do.”
