Glass Performance Options

We use commercial grade glass in all of our glass conservatory roofing. Our roof glass consists of 2 panes of 1/4" tempered glass forming a 1" tempered insulated glass package. Each glass panel is layered with silver/oxide/titanium coatings to reduce heat gain, harmful UV rays and reduces glare.

The Quad 4 glass package is a dual-pane insulating glass system constructed of 2 glass lites of PPG Solarban 60 glass and a mixture of Argon and Krypton gas which increases insulating value.

Solargate 9  bulletQuantum 2--Ultimate Solar Control
The Q Power 10 glass system is constructed of 2 lites of PPG Solarban 60 double-strength glass separated by a film that is coated with special UV inhibitors which improves the insulating power and blocks 99.5% of harmful UV radiation from the sun. The two air chambers created by the special film are filled with Krypton Gas greatly improving the insulating power of the overall unit. This is the perfect glass for hot summer days and cold winter nights.

R-Value:

Measures the insulating value, or resistance to heat gain or loss. The larger the number, the more resistant the glass is to heat flow.

U-Factor:

Measures how well the glass prevents heat from escaping. The lower the U-value, the more resistant the glass is to heat escaping.

Solar Heat Gain Coefficient (SHGC):
Measures how well a product blocks heat caused by sunlight. The lower a window's SHGC, the less solar heat it transmits.
Ultraviolet Light Transmittance:
Can cause fabric fading and degrading. Percentage shows how much UV Transmissions comes through the glass.
