Combining an outer pane of Pilkington OptiFloat with an inner pane of Pilkington KS (Soft Coat Low-e) together with ThermoBar warm edge spacer bar and Argon Gas fill. The Low Emissivity (Low-e) pane reflects back internal heat attempting to leave the room retaining a higher temperature within your home.
Introducing a solar neutral pane such as Pilkington OptiWhite which has a reduced iron content (Low-i), means a greater proportion of free energy transmits into your home compared to standard float glass. This is known as Solar Gain and qualifies your overall window product to become "A-Rated".
