A range of extremely high performance Insulating Glass Units using three panes of glass to dramatically reduce the amount of heat loss from buildings.

Thermal Stress is created when one area of a glass pane gets hotter than an adjacent area. If the stress is too great then the glass will crack. The stress level at which the glass will break is governed by several factors.

Optikool™ and EZ-KOOL® are green, optimised solar absorbing glasses, providing significant improvement to occupant comfort. The products reduce the heat entering through a vehicle's glazed area by around 20 per cent when compared to a car equipped with standard tinted glass.
