Saint-Gobain Glass has announced the launch of the next generation of its SGG Planitherm Total product. According to the company, this will make it easier than ever before to achieve cost effective band C window energy ratings (WERs) & make A-ratings a viable option for many more standard window configurations. Called SGG Planitherm Total+, the new product will fully replace the existing product & aims to offer at least 5KWh/m2/year WERs improvement over its predecessor, the equivalent of half a WERs band. While the optimum centre-pane U-value remains unchanged at 1.2 W/m2K, the G-value has increased to 0.71, often taking existing windows into the next band. This development was pioneered in the UK, using the magnetron coating facility at Eggborough.
