Excellent heat transfer coefficients for Super Spacer® and TriSeal™: Edgetech awarded top marks by Fraunhofer Institute

The excellent evaluations of our two top products Super Spacer® and TriSeal™ by the Fraunhofer Institute represent a further milestone in the triumphal progress of Edgetech technology in Europe”, comments Torsten Keemss, General Manager, Edgetech Europe GmbH. “The calculations of the Fraunhofer Institute are based on typical usage scenarios for the Super Spacer® and TriSeal™ spacers for conventional and structured glazing.”Tests were carried out on twelve versions with four different edge seals and three different types of window.First class heat transfer coefficients, unparalleled on the rest of the market, were achieved in all the tests. The Super Spacer® Premium in a wooden window with 5 mm hot melt butyl achieved a value of 0.029 W/mK, for example, the TriSeal™ achieved a value of 0.030 W/mK with 4 mm PU.

Torsten Keemss: “We deliberately chose to work with the Fraunhofer Institute for window installations as these are closest to the normal setup in practice and thus more representative. These results are extremely valuable for our customers, as they show that Edgetech products produce excellent results and can make use of this strength in practice. Further certifications for setups orientated especially to the Eastern European market and triple glazing according to the Passive House standard are planned for this summer.
