Advanced insulating glass silicone
Dow Performance Silicones will introduce an advanced insulating glass silicone technology designed to further enhance energy performance and improve living comfort, at Glasstec.
The company will also reinforce its new product brand name, Dowsil, for its heritage Dow Corning high-performance silicone-based building products.
Marketing manager Markus Plettau said: “Dowsil silicones in facade applications are already proven to perform in excess of 50 years. Our cutting-edge silicone technologies are at the forefront of innovation in modern glass facades and continue to influence not only the longevity of a building, but also the quality, design and beauty of the built environment.”
Stringent environmental regulations have forced architects, planners and energy consultants to re-examine the design of modern glass facades due to their significant impact on energy loss and CO2 emissions, the company said.
Warm edge spacer systems for insulating glass (IG) already offer improved thermal performance and surface temperatures, but so far the IG edge sealants still contribute to heat losses.
Therefore, the warm edge spacer systems will soon be complemented by the launch of the first silicone providing low thermal conductivity: Dowsil 3364 warm edge silicone sealant for IG.
Suitable for double and triple glazed insulating glass units, Dowsil 3364 is a secondary edge sealant that offers up to 30% lower psi-values in warm edge designs when compared to standard insulating glass silicones and helps to further lower the U-value, depending on the facade system, by up to 5%.
