Thermashield energy-efficient windows

With energy use gaining extensive media coverage, Trend Windows and Doors has addressed energy efficiency with Thermashield, now offering energy ratings up to 7.5 stars and a more precise way to shield homes from weather extremes.

The extensive selection of windows and doors in the Thermashield range is extremely efficient in energy terms and delivers very low u-values of 1.9, with single- and double-glazing options and low-e glass combinations (NFRC figures). Low air infiltration and solar heat gain coefficient levels of around 0.3 mean Thermashield can offer significant savings on energy bills.
