Technical Data

Heat reflection: measured by taking the opposite or inverse of the glazing solar factor. Solar factor is the percentage of the total solar radiant heat energy entering the room through the glass.

Thermal insulation: a measure of the rate of heat loss through the glazing. A principle reason for installing energy efficient glass, the lower the u-value the better the glass is at retaining heat.

Glare reduction: measured by the inverse of ‘light transmission’, the proportion of the visible light spectrum that is transmitted through the glass. It is important to reduce the transmission of concentrated light, especially in the roof, to maximise visual comfort.

Self-cleaning glass: the self-cleaning coating is fully-integrated into the surface of the glass ensuring its permanency. In a process called ‘catalysis’ the coating uses UV rays from the sun to break down organic dirt and turns the surface hydrophilic. Rain or hosepipe water then forms a sheet of water and rinses the dirt away.
