IGLASS insulating glass consists of two or three float glass panes 3-10 mm thick with an air cavity between 6-24 mm glass. The surface of the insulating glass can be optically divided by a decorative grid placed in the cavity.
The thermal insulation capacity of the product is expressed by the value of the heat transfer coefficient Ug (W.m-2.K-1). Compared to single glazing, insulating double glazing allows 40-50% reduction in heat loss. If high light transmittance is desired and at the same time transparency is to be limited, ornamental glass can be used in the insulating glass composition.
The shapes of the insulating glass may be regular or irregular.
