Glass ~ this material is produced by fusing together soda, lime and
silica with other minor ingredients such as magnesia and alumina.
A number of glass types are available for domestic work and these
include:-
Clear Float ~ used where clear undistorted vision is required.
Available thicknesses range from 3 mm to 25 mm.
Clear Sheet ~ suitable for all clear glass areas but because the
two faces of the glass are never perfectly flat or parallel some
distortion of vision usually occurs. This type of glass is gradually
being superseded by the clear float glass. Available thicknesses
range from 3 mm to 6 mm.
Translucent Glass ~ these are patterned glasses most having one
patterned surface and one relatively flat surface. The amount of
obscurity and diffusion obtained depend on the type and nature of
pattern. Available thicknesses range from 4 mm to 6 mm for
patterned glasses and from 5 mm to 10 mm for rough cast glasses.
Wired Glass ~ obtainable as a clear polished wired glass or as a
rough cast wired glass with a nominal thickness of 7 mm. Generally
used where a degree of fire resistance is required. Georgian wired
glass has a 12 mm square mesh whereas the hexagonally wired glass
has a 20 mm mesh.
Choice of Glass ~ the main factors to be considered are:-
- Resistance to wind loadings. 2. Clear vision required.
- Privacy. 4. Security. 5. Fire resistance. 6. Aesthetics.
