Is There Such A Thing as an A-Rated Window?
“I don’t think anyone realised how quickly an A-rating would be achieved, but, in reality, it has only been achieved by using triple glazing, krpton gas and slim outer frames requiring specialist glazing. That’s all well and good, but the hard facts are that in reality, A-rated windows as they currently stand are simply not commercial viable. The C-rated window is by far the most commercially viable, achieves energy efficiencies that compare well with the A-rated versions, and is not crippling expensive” – David Riley, Quality Manager, Duraflex – Source: Letter from David Riley published in Window Fabricator and Installer letter. According to the Energy Saving Trust, a household fitting the minimum C-rated windows could cut carbon dioxide emissions by more than half a tonne per year. This is a huge saving, especially as it is known that 20% of heat loss from a home takes place via the windows. As standard, VANTAGE has consistently complied with Building Regulations Document L in respect of C-rated windows. VANTAGE has another great new product and now offers SGG PLANITHERM 1.3. Due to its excellent thermal insulating performance, offering an optimal centre-pane U-value of 1.3 W/m2K SGG PLANITHERM 1.3 is yet another ideal solution for compliance with current Building Regulations relating to energy efficiency – Building Regulations Document L. |
