Our range of timber windows are supplied factory fitted with market leading Pilkington energiKareTM gas filled units (to EN 1279 Pt3) as standard – see Pilkington.
The Pilkington energiKareTM range utilises low emissivity ‘Low-E’ coated glass to reflect heat back into a building, greatly improving its thermal efficiency and also maximising the use of freely available heat from the sun.
Windows energy rated A and above will be supplied with Pilkington Optiwhite glass as standard. This is available as an optional extra on other windows. Windows energy rated B and under will be supplied with Pilkington Optifloat KS glass as standard.
