The 0.8W/m2K Window

Zero Carbon Homes

UK housebuilders can now fit affordable windows which achieve U-values of just 0.8W/m2K - well below the 1.8W/m2K routinely specified. L.B. Plastics Ltd, has developed the new Sheerframe HED window which brings together a thermally superior profile system and new manufacturing technology.The Sheerframe HED (Homogenous Energy Dynamics) system creates stronger, lighter and significantly more thermally efficient windows, offering housebuilders a simple and cost effective route to achieving window U-values of just 0.8W/m2K in their drive towards viable zero carbon homes. Such a low U value is equivalent to the rating required for Category 5 and 6 star rated dwellings in the Code for Sustainable Homes.

Sheerframe HED allows window U-values to be cut significantly while still providing homebuyers with low maintenance, visually appealing and enhanced security windows designed to cut energy bills. Like all Sheerframe systems, broader sustainability issues are also comprehensively addressed - the profile is lead-free in composition and 100% recyclable.

This new system revolutionises the performance and fabrication of windows. Until now, performance at this level could only be achieved by very specialist and fantastically expensive, often unsuitable windows with long delivery lead times, from northern Europe. The Sheerframe HED system is designed specifically for the mainstream UK housebuilding industry and is available now.

The Sheerframe HED system delivers windows in all the most popular styles in numerous coloured foil and painted finishes, including standard casements, fully reversibles and tilt & turns. Windows made using HED retain their excellent visual appeal, which is perfectly suited to British architectural styles.
