Choosing your windows

Solar Control Glass Filters the sun's rays and lower solar reflect!

What is solar control glass ?

Excess heat and glare caused by the sun can be a major source of discomfort in some indoor environments, especially those with glass roofs, conservatories or with large glazed areas.
The latest double glazing window solutions for solar control reflect and filter the sun’s rays, allowing natural daylight into the room, but without uncomfortable visual glare. Rooms can be kept cooler during sunny periods, reducing the need for air-conditioning.
A variety of solar control glass solutions are available, depending on the level of solar control needed. The glass is manufactured by tinting and/or applying a metallic coating (see online and offline coatings). Online coating offers a greater range of performance and a more neutral appearance for solar protection glass.

Solar Heat Gain Coefficient or ‘g’ value

The Solar Heat Gain Coefficient (SHGC), which measures a window’s ability to transmit solar energy into a room, is measured in value from 0 to 1. The SHGC is commonly referred to as the g-value, or solar factor. The lower a window’s g-value, the greater its ability to insulate against solar heat build up.

Combinations with other double glazing window solutions

Solar control glass can be incorporated into double glazing window with combinations of selfcleaning, Low E and decorative glass solutions (see Which Glass Combination). Combining solar control glass with Low E thermal insulation in one double glazing unit, offers optimum temperature comfort all year round.
