Currently nearly all double glazed units are
constructed with Low E glass (low emissivity) which
has a noticeable tint. Our new Ultra Clear Low E
Units reduce the visible tint effect and increases the
Daylight/ Solar Factor and in appropriate conditions
may reduce the heating energy requirement.

Emissivity glass


Emissivity glass is a coated glass on one face of the glass and has the effect when used in the construction of a double glazed unit of reflecting the long wave radiation or heat back into the room.

All emissivity glass has a slight tint which varies from manufacturer to manufacturer.  There are two types of emissivity glass, one is referred to as Hard Coat and the other Soft Coat.

The Hard Coat is applied during manufacture referred to technically as Pyrolitic and Soft Coat is applied to the glass after the glass has been manufactured in a vacuum spluttering process.

Slimlite is manufactured with preferred hard coat, which forms part of the glass as opposed to soft coat which is applied on the face of the glass after manufacture.

Hard coat has very good emissivity or insulation value, good light transmission and reasonable solar gain at daylight times.

Overall the use of hard coat emissivity in the construction of Slimlite Ultra Clear Self Cleaning Double Glazed Units when glazed on site, is virtually indistinguishable from single glazing, unless from close up inspection.
