Announcing the Next Generation of Pilkington K Glass™

12 October 2011

Pilkington K Glass™ has long been the leading choice in low-emissivity glazing, ensuring consumers save energy and money off their fuel bills. With today’s launch of Pilkington K Glass™ S, customers can benefit from an extended range of energy-efficient glass solutions and offer a soft coated product to householders from Pilkington, the brand they know and trust.


Announcing the launch, David Pinder, Managing Director, Pilkington Building Products UK, said: “This advance in the Pilkington K Glass™ product range means our coated glass range offers the widest choice on the market. Customers can now easily find a solution for any processing technique or to achieve an A rated Window Energy Rating (WER) in any framing system.”

Pilkington K Glass™ S is a single stock coated glass which can be used in both annealed and toughened formats, with the added advantage of retaining the same thermal performance and neutral appearance. Once fabricated into an IGU, it can be used in all types of windows and in a variety of glazing applications from new build, to replacement windows in existing homes and conservatories. Pilkington K Glass™ S helps ensure windows exceed Part L 2010 Regulations and provides an enhanced solution for changes expected in 2013 and 2016. When combined with Pilkington Optiwhite™ in an insulating glass unit, it qualifies for Pilkington energiKare™ energy-efficient glazing and ensures a WER rating of A in all frame materials.

BFRC, Certass and FENSA have all certified the K Glass™ S range as being interchangeable with any other low emissivity product, with equal or inferior performance, without the need to obtain new simulations.

The product is to be offered through selected routes to market from 1st November 2011 and will become fully available over the following months. Initially supplied from Pilkington’s coating plant in Europe, production of Pilkington K Glass™ S will move to a new production line following its completion in October 2012. The establishment of a £36M coating line at Cowley Hill in St Helens was announced in April of this year. Subject to final approval, it will be supported by a £5 million award from the government’s Regional Growth Fund.

The good news is whether customers are looking for the ease of use of the original hard coat product or the enhanced performance of Pilkington K Glass™ S, the UK’s favourite low-emissivity solution now suits all and Pilkington K Glass™ looks set to remain just as popular in years to come as it is today.
