New DOWSIL™ silicones improve energy efficiency 08 January 2019

Dow has recently introduced two new advanced silicones that have been designed to further enhance energy performance and enable productivity gains in glass insulation and structural glazing applications.

DOWSIL™ 3364 Warm Edge IG sealant is a secondary edge silicone that offers up to 45% lower thermal conductivity and 25% lower psi-values in warm edge designs when compared to standard insulating glass silicones. This new patented ENERGY STAR® product designed to gain European approval (ETAG 002) helps to further lower the U-value of the curtain wall by up to 5% without changing the overall design. The DOWSIL™ 3364 sealant also contributes to a higher level of comfort by raising the internal surface temperature of the glass, reducing the risk of condensation and mould growth.

Increasingly stringent environmental regulations has led architects, planners and energy consultants to re-examine the design of modern glass façades to capture significant energy gain and CO2 emissions reduction potential. Advances in lowering U-values, condensation risks, and insulating glass edges are key topics in the design of high performing façade designs.

Next generation silicone
Designed to increase productivity, DOWSIL™ 994 Ultra-Fast Bonding sealant is ideally suited for structural glazing and other bonding applications such as internal partition wall bonding, solar thermal and window bonding, etc, where strong connections and short cycle times are required. With European approval (ETAG 002), high structural capability and ultra-fast cure, this new product enables continuous production for fast onward processing, automated fabrications and specific bonding designs.
