FEATURES AND APPLICATIONS

reducing unwanted heat gain;

reducing glare;

adding value to the property;

reducing cooling costs;

improving privacy during the daytime;

furniture, decorative displays etc.

DID YOU KNOW?
the thicker the tinted glass, the darker the appearance and colour becomes.
As the thickness increases, the glass absorbs more heat and therefore maybe more prone to thermal breakage if glazed in annealed form;

toughening or heat strengthening will prevent thermal breakage;

for more information on the thermal safety of annealed glass, refer Thermal Breakage.

COMPARING CLEAR AND TINTED FLOAT GLASS

Clear float window pane
Clear glass lets in a very high proportion of the sun’s direct energy which creates heat, glare and discomfort for the occupant.
Air conditioning costs increase as well.

Tinted float window pane
Tinted glass acts to absorb the sun’s direct heat and depending on the tinted product selected, it is 30-50% more efficient than clear glass in keeping heat out of a room.

Tinted float is produced by adding a colourant during a clear float production run. The most common colours are grey, bronze, green and blue. Apart from its function as an aesthetically pleasing glass, tinted float is primarily designed to reduce solar heat entry and glare which, from an occupants point of view, increases comfort levels and reduces cooling costs. Tinted float is also referred to as a heat absorbing glass, in that the glass reflects little solar energy. Because of this heat absorption quality, some thicker tints in certain situations may require heat strengthening or toughening to cope with this thermal stress.
