Some warm edge spacers lack the rigidity required for triple glazing and can’t cope with the additional stress, or the higher thermal standards that will be required as building regulations become more demanding. If the unit breaks down, the windows won’t be saving any energy! Homeowners buying new windows expect them to last. They expect to open and close them, see clearly through the glass and save them money over many years. So the long life and durability of warm edge spacer bars is a key expectation – for double and triple glazed windows. Homeowners who invest in high performance windows expect to enjoy a warmer, more comfortable home with lower heating bills, now and for many years to come. They don’t expect their window efficiency to wear out and their savings to run down after a few years. Best by test The warm edge spacer bar’s primary functions are to keep the panes of glass apart and reduce heat loss from the edge of the sealed unit. It should also work with sealant and desiccant to act as a barrier, stopping insulating gas leaking out and moisture getting into the sealed unit. If the spacer bar doesn’t have an effective backing barrier, it will not prevent gas and moisture penetration. As gas leaks out and moisture seeps in to the sealed unit it will become steadily less energy efficient and fail. That will be a huge disappointment and source of frustration to homeowners buying windows to protect against rising heating bills. Unlike other warm edge brands which have only a partial barrier or are sold without any backing barrier, Swisspacer has a high tech gas barrier which stops 100% of gas and moisture penetration through the spacer bar. It’s also the most popular choice for the ultra energy efficient Passivhaus standard: 60% of Passivhaus windows and 90% of Passivhaus curtain walling has Swisspacer inside. As we place higher demand on windows’ energy performance, demand on the warm edge spacer bar grows. Swisspacer is tried and tested and ticks all the boxes. In well made units in well-made windows, it will contribute to a lifetime’s energy saving. For more information, visit: www.swisspacer.com
