Pilkington K Glass is a low emissivity hard coated glass. The ‘invisible’ coating on the glass reflects heat back into the room whilst also letting in free heat from the sun.
New to the Pilkington K Glass range is Pilkington K Glass OW, which is a development from the original Pilkington K Glass. Pilkington K Glass OW combines the ‘K’ coating onto optiwhite (low-iron) glass, which allows improved clarity, light transmission and improves solar gain.
We now stock Pilkington K Glass OW as standard in place of the original Pilkington K Glass for the same cost, giving our customers a greater enhanced product for no further cost.
How is Pilkington K Glazed?
Pilkington K Glass or K Glass OW usually forms the inner pane of a DGU once glazed into a frame, with the coated face of the glass sealed into the centre of the DGU so it cannot be physically touched.
Complying with Building Regulations Part L 2010
Using Pilkington K Glass OW the new Building Regulation Part L 2010 changes can be met with ease, which states that in order to comply; the complete window (including the frame and the glass) should either:
- Achieve an overall U-value of 1.6 or lower
- Achieve a minimum Energy Rating of C
Pilkington K Glass OW helps windows to achieve high Window Energy Ratings to demonstrate compliance with the changes to Part L.
Energy Saving Trust and Pilkington energiKare
Windows containing Pilkington energiKare can achieve the EST’s (Energy Saving Trust) Energy Saving Recommended status. Once incorporated in suitable framing material it will normally achieve a minimum BFRC Window Energy Rating of C and can be improved to B by the addition of Argon gas filling. We are a licensed IGU processor of Pilkington energiKare Insulating Glass Units.
How does Pilkington energiKare DGU differ?
Pilkington energiKare is different to standard double-glazing as it works in two ways. Pilkington energiKare is made up of two special types of glass, Pilkington K Glass OW, which stops heat escaping and Pilkington Optiwhite, a special ‘extra clear’ glass which allows more solar heat in through the windows. This effect is known as solar gain and as it comes from the sun it’s free of charge.
