Low E One
The most advanced thermal insulation performance glass
Superior performance ‘single-stock’ low-E glass with an optimum centre-pane U-value of 1.0 W/m2K
Designed specifically to minimise heat loss, Low E One is ideal for achieving the lowest U-values. The advanced coating of Low E One offers insulating levels far in excess of the minimum requirements set out in Approved Document L of the Building Regulations.
Its excellent performance capability is in the name – a double glazed sealed unit featuring Low E One will deliver an optimum centre-pane U-value of 1.0W/m2K (16mm, 90% argon-filled cavity)
If higher thermal insulation levels are your goal, Low E One represents the perfect choice.
This type of glass is amongst the most advanced thermal insulation performance, Utilising Europe’s best selling low-emissivity (low-E) glass and one of the UK’s leading offline low-E coating brands.
Low E One - optimal performance
Comfort and aesthetics
• Helps to eliminate cold areas around windows resulting in greater comfort
• Reduces incidence of condensation on the inner pane
• Neutral appearance in both transmission and reflection
• Maximises entry of natural daylight
• Maximises use of living and working areas
Enhanced thermal insulation
• An optimum centre-pane U-value of 1.0W/m2K (16mm, 90% argon-filled cavity), comfortably meeting current Building Regulations requirements for the whole window U-value for all frame types.
• Ideal for residential new build, plus light commercial new build and renovation projects using steel or aluminium frames.
• Scope for considerable reductions in heating requirements versus standard glass.
• Environmentally friendly solution, given the lower CO2 emissions associated with reduced energy consumption
