CURVED GLASS

The glazing system must be designed to drain out all water in the rebate and a void
must exist under the unit so that moisture is not trapped against the edge of the
glass.

Generally units should be glazed with a minium 3mm clearance between the glass
face to rebate a minium 3-6mm clearance under the unit in the rebate (size of
block) and a minium 12mm cover or bite in the rebate. Dry glazing of units is always
recommended but if units are to be glazed or bedded into compounds or sealants
it is imperative that compatible sealants are used or edge failure may result.

Insulated glass units (IGU's) or double glazed are a significantly more energy
efficient glazing system than single glazed windows. Double-Glazed-Glass-Biglt is
estimated that up to 30% of heat entering the home and up to 50% of winter heat
loss is a result from the use of single glazing.

PRIVACY GLASS

Privacy glass is produced by the sandblasting or acid etching of clear sheet glass. This creates
a pitted surface on one side of the glass pane and has the effect of rendering the glass
translucent by scattering the light which passes through, thus blurring images while still
transmitting light.
APPLICATIONS
• To achieve visual privacy while still allowing light to pass through.
• Decorative patterns may be created on plain glass by using wax or
other inhibitors to retain transparent areas.
• Privacy glass in light bulbs is used for evenly distributing the light
from the bulb's filament across its surface area.
• To distribute light uniformly in a photographic contact printer.
• To create an airtight seal in tubes.
