glass performance

Choosing the correct glass

All performance for C.O.G. (centre of glass) ratings are based on Vision v4.0 simulations. All C.O.G U- and R-values are based on ASHREA Winter Conditions. Framing, cladding, frame type and other items will affect the overall thermal values of a complete window.

Notes
Values are in METRIC. All performance for C.O.G. (centre of glass) ratings are based on Vision v4.0 simulations. All C.O.G U- and R-values are based on ASHREA Winter Conditions. Framing, cladding, frame type and other items will affect the overall thermal values of a complete window.

U Value: the total heat transfer out of a window (Btu/hr-sq ft-F or W/sq m- C). The lower the number the better the glass. 

R-Value: the amount of heat retained by the window. The higher the number the better the glass.

Solar Heat Gain Coefficient: the amount of solar radiation which enters the house through radiation. This is expressed as a dimensionless number between 0 and 1. It represents the heat gain through 3mm clear glass.

Visible Light Transmittance: measures how much of the visible light is entering the building through the glass. 1.0 would mean all of the light was getting through and 0 would mean none of it was getting through. Our atmosphere naturally filters out 5% of the visible light. Clear glass with no coatings lets in approx. 90% of visible light.
