Halo SmartSash

SmartSash PVC-U windows and doors can be manufactured with a U-value as low as 0.7W/m2K. This remarkable performance is achieved using a standard 70mm outer frame depth and off the shelf glazing, hardware and other components.

SmartSash is undoubtedly one of the most significant developments in window design this century. No other UK based PVC-U systems manufacturer is able to offer such exceptional thermal performance using standard components.

SmartSash is a development of Halo s market leading System10 PVC-U windows and doors. System10 has been used to great success for over 25 years and is held in high regard by Local Authorities, construction professionals and homeowners alike.

Along with the remarkable thermal insulation performance comes a commensurate reduction in sound transmission. Reductions of up to 50db can be achieved.

Exceptional performance the result of exceptional design

For SmartSash to deliver such exceptional performance a number of patented design concepts have, for the first time, been incorporated into one window system. They include:
A unique system glazing that allows glazed units up to 48mm to be fitted
A six chamber sash profile that all but eliminates cold bridging
Foam filled thermal inserts
Specially designed seals that prevent heat loss around glazed units, between the sash and the frame, and between the frame and the wall.
