To help you in choosing the right Walshs product for your project, we have developed Performance Data charts for your reference
The data is measured using glass only and all care should be taken when evaluating our published data that the same environmental conditions have been used.

|
NOMINAL THICKNESS |
Identifies the glass thickness. |
|
VISIBLE LIGHT TRANSMISSION |
The percentage of visible light that passes directly through the glass. The higher the percentage, the more daylight gets through. |
|
VISIBLE LIGHT REFLECTION |
The percentage of visible light reflected toward the exterior. |
|
SOLAR TRANSMISSION |
The percentage of normal incident visible light and solar energy that passes directly through the glazing. |
|
SOLAR REFLECTION |
The percentage of normal incident visible light and solar energy reflected toward the exterior. |
|
UV TRANSMISSION |
The percentage of UV light transmitted measured in the light range of wave lengths shorter than 380 nanometres. A lower number is better. |
|
U VALUE |
The measure of the rate of heat gain or loss through glazing caused by environmental differences between indoor and outdoor air. The lower the value the better the insulation. |
|
SHADING COEFFICIENT |
The ratio of solar heat gain through glass relative to that through 3mm clear glass. A lower number indicates a better performance. |
|
SHGC (SOLAR HEAT GAIN COEFFICIENT) |
The proportion of total solar radiation that is transferred through glass in normal circumstances. A lower number indicates a better performance. |
