Glass is a chemically inert, brittle, hard and transparent construction material. Foamed or cellular glass is used for vapour proof insulation and in spun form glass fibers are used as acoustic and thermal insulation. There are different types and colors of glass, these include:
Transparent glass, of different thickness and properties. e.g. 4 millimeter, 6 millimeter, 10 millimeter, toughened, laminated, solar reflective.
Translucent glass, which allows light but limited vision. Arctic, crossed reeded, sand blasted, large Flemish, small Flemish, broad reeded, narrowed reeded, Pacific.
Glass brick also known as glass block is an architectural element made from glass. It is used in areas where privacy or visual obscuration is desired while admitting natural or artificial light. Thermal transmission, noise, dust etc may also be controlled. It is composed of two halves of pressed glass fused together. This hollow center is partially evacuated, which provides a partial vacuum with good insulating qualities. The use of glass blocks, which was limited to front doors and bathrooms, is now increasing due to modern technology and innovativeness to add decorative effect. But the use of glass blocks is only for non load bearing walls.
