Guardian is pleased to reveal our next generation in Low E glass technology – ClimaGuard A+, specifically designed to meet the bespoke requirements of the Window Energy Rating calculation. ClimaGuard A+ gives flexibility back to the independent glass and glazing industry, by utilising the same centre pane U value and Solar heat gain performance as some of the other best known Low E glasses on the market, ClimaGuard A+ can be used to substitute many Low E glasses used under BFRC and Certass window energy rating licences at no additional cost.
By combining the durability of modern soft coat Low E glass, with the exceptional performance that can only be achieved through magnetron glass coating technology, ClimaGuard A+ retains the same 0,05 emissivity of its predecessor ClimaGuard A, producing the same 1.2 U value W/m2K. However, ClimaGuard A+ has improved solar heat gain performance; increased to 71%, allowing higher levels of solar heat to pass through the glass, helping to heat our homes for free. The thermal performance (1.2 U value) of ClimaGuard A+ means that the free heat gains are retained helping to reduce heating costs.
In addition to this, ClimaGuard A+ has an increased light transmission of 82% which allows more daylight to pass through your windows, helping to reduce the need for artificial lighting during daylight hours. When used in Window Energy Rated windows, ClimaGuard A+ achieves some of the best results on the market. A rated windows can be easily achieved using ClimaGuard A+ in an insulating glass unit, comprised of a 20mm Argon cavity, high performance warm edge spacer technology and a clear float outer pane, which with nearly all uPVC casement windows on the market will achieve an A rating. ClimaGuard A+ also achieve A & B ratings in Sash and Tilt & Turn windows using a similar configuration. On top of this performance in Window Energy Ratings, ClimaGuard A+ will easily exceed current Building Regulation standards of either a C rated WER or a whole window U value of 1.6 W/m2K, using a basic,economical, insulating glass unit comprised of ClimaGuard A+, 20mm Argon cavity, aluminium Spacer bar and a clear float outer pane, ClimaGuard A+ achieves current Building Regulation in the most economical way on the market. This makes ClimaGuard A+ the ideal product to keep your insulating glass units at the right price to meet market demand.
