Super Spacer® spacers receive Passive House certificate

In January 2016, three Super Spacer® spacer systems from Edgetech were certified by the Passive House Institute in Darmstadt.

As the world’s first manufacturer of flexible, foam-based edge spacer systems, Edgetech is a pioneer of Warm Edge Technology and thus energy-efficient construction.
All three of the tested Super Spacer® spacers significantly exceed the required minimum specific edge resistance of 1.50 m K/W and are therefore certified for an Arctic climate, as well as for all climate zones with lower demands. The Warm Edge Super Spacer® Premium, with an edge resistance of 6.11 m K/W, was placed in the highest efficiency class phA+. This product also achieves amongst the best values for its thermal transmittance coefficient Ψ of up to 0.028 [W/mK] (source: Bundesverband Flachglas e.V. – German flat glass association) and thus is today one of the most energy efficient spacers on the market.
The moisture permeable foam matrix with integrated desiccant is the major reason for the low thermal conductivity and thus good thermal insulation values of the Super Spacer® product range. Thanks to the non-metallic composite material, the glass retains a uniform temperature over its entire area, radiative cooling of the surfaces is reduced and the dew point is shifted downwards. In addition, the combination of a multi-layered vapour barrier and outer sealing material seals the window against moisture ingress from the outside and gas losses from the inside. Formation of condensation is close to zero.
