ADVANCED GLAZING The energy saving glass About Iplus Iplus benefits How Does Iplus Work? Technical Data Iplus and the environment Prices and Availability Specify About Iplus Iplus, the energy saving glass Iplus double glazing units offer improvements of over 60% in thermal insulation when compared with ordinary double glazing. This means 60% less heat loss through windows and doors. Even compared with some other energy saving glasses, Iplus is over 30% more efficient. The unique, patented, feature of Iplus is a micro thin layer of silver on the inside of the glazing unit which acts as a heat reflective layer alloowing solar radiation into the building, but minimising heat loss. The coating also has the additional benefit of largely filtering out ultra-violet rays, thus reducing glare and minimising fabric fade. Iplus is neutral, just like ordinary glass Other energy saving glasses are slightly coloured or look hazy under certain light conditions. Iplus is different. The patented silver coating means that Iplus is virtually indistinguishable from ordinary glass. To find out how Iplus works, click here.
