Pilkington K Glass™ S
Pilkington K Glass™ S is a UK-manufactured, soft-coated, low-emissivity (low-e) glass intended to reduce levels of heat escaping through the glass of a window.
It has a neutral appearance and allows the suns heat to pass through the glass, making it an ideal choice for fabricators, glaziers and installers looking to optimise Window Energy Rating (WER) and meet regulatory requirements (e.g. minimum band B for windows in Table 4.2 of The Building Regulations 2010 (England) Approved Document L Volume 1).
