New Pilkington K Glass™ OW Provides A Ratings Boost

Pilkington takes another step forward in the energy efficient evolution with the introduction of Pilkington K Glass™ OW - the first development in the Pilkington K Glass™ range of energy efficient glazing products designed for use within the new family of Pilkington energiKare™ products.

Pilkington K Glass™ OW is an improved form of Pilkington K Glass™, the UK’s leading low emissivity glass product.  Offering increased light transmission, improved solar gain and a brighter appearance, Pilkington K Glass™ OW helps to achieve improved Window Energy Ratings (WERs) in the greatest available range of profiles.So, when incorporated into the Pilkington energiKare™ system, Pilkington K Glass™ OW makes it even easier to produce A-rated windows.

Andy McDowell, National Business Development Manager, Pilkington, said: “Pilkington energiKare™ is going from strength to strength – we now have more than 350 Partners signed up to the scheme and Pilkington K Glass™ OW is an invaluable addition to the range, allowing the cost effective production of windows that achieve an A rating.  The brighter appearance might also prove useful for those customers seeking to improve the appeal of their current offering without necessarily wishing to increase the rating to straight A’s – Pilkington K Glass™ OW can provide the solution here too.

“The increase in solar gain helps to improve window energy ratings meaning lower heating bills, whilst the increased light transmission helps to create a brighter environment reducing the need for artificial lighting and further reducing energy costs. As we move a step closer to the changes to Part L of the Building Regulations in 2010, these factors are becoming ever more important.”

Pilkington energiKare™ is made up of two special types of glass, Pilkington K Glass™, the UK’s best selling low emissivity glass which stops heat escaping and Pilkington Optiwhite™, a special ‘extra clear’ glass which allows more solar heat in through the windows. Pilkington energiKare™ IGUs achieve a minimum BFRC Window Energy Rating of C and can be improved to B or A by the addition of Argon gas filling, warm edge spacer bar technology or the introduction of the new Pilkington K Glass™ OW. All windows containing Pilkington energiKare™ have the potential to gain the Energy Saving Trust’s Energy Saving Recommended status.

Achieving a similar performance to soft coat glass, with none of the associated increased processing costs, handling problems and shelf life limitations, Pilkington K Glass™ OW is suitable for use in PVC-U, timber, and aluminium profiles, for both new and replacement windows. It can also be toughened, laminated and glazed in the same way as the original Pilkington K Glass™, offering a wide variety of options to range.

Available exclusively for use within Pilkington energiKare™ insulating glass units, stockists of Pilkington K Glass™ OW will also benefit from the association with the most recognised low E glass brand, along with the backing of an extensive promotional campaign.
