New Thermally Improved Insulating Glass Spacer

The double sealed insulating glass with a
hollow metal spacer is today’s mostly used IG
edge design. As the thermal performance of the
glazing has been improved dramatically over the
years, the attention has been turned to the edges
to minimise heat losses caused by the high
thermal conductivity of the spacer.
The increasing interest in the so-called „warm-edge“
technology has brought out new edge seal
designs. This paper will describe the effect of
thermally improved spacers on energy saving and
condensation resistance with particular reference
to the new FLACHGLAS plastic spacer. The
existing and future regulations in Germany for
determining U-values will be compared.
Replacing conventional metal spacers by
warm-edge systems can be an additional paying
step to enhance window performance from which
manufacturers and consumers can benefit. The
new edge design must combine thermal
improvement and product durability at a
competitive price.
