Various sized cuts of 1 ⁄ 2 in (13 mm) drywall with tools for maintenance and installation . Drywall (also called plasterboard, dry lining, [1] wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of ...
It can be used on the exterior of buildings as a base for exterior plaster systems and sometimes as the finish system itself. Cement board adds impact resistance and strength to the wall surface as compared to water resistant gypsum boards. Cement board is also fabricated in thin sheets with polymer modified cements to allow bending for curved ...
Moisture Content-- BS 1088 plywood must have a moisture content between 6% and 14% when it leaves the factory. Finishing -- Boards will be sanded on both sides equally. Length & Width -- The length or width of a board produced as a standard size shall not be less than the specified size nor more than 6.3 mm (0.25") greater than the specified size.
Brick has excellent fire resistance; planks or weatherboards made from fibre cement or steel have high fire resistance; aluminium and reconstituted timber products have good fire resistance, and timber weatherboards and plywood sheets have poor fire resistance. Composite cladding typically consists of panels 3–5 millimetres (0.12–0.20 in ...
Sheet sizes vary slightly from manufacturer to manufacturer but generally they range between 2400 – 3000 mm in length and 900 –1200mm in width (600 & 450 mm increments). This manufactured size minimizes on-site wastage as residential floor, wall and roof structures lay structural members at 450 or 600mm centres.
The plaster veneer method begins with the hanging of specially designated drywall ("blueboard"), in the conventional manner. [1] [3] N.B. In North America, the color of the face paper of drywall indicates its intended application: white for standard, green for moisture resistance, etc. Plaster veneer wallboard is blue or gray. [4]
Plaster was first used as a building material and for decoration in the Middle East at least 7,000 years ago. In Egypt, gypsum was burned in open fires, crushed into powder, and mixed with water to create plaster, used as a mortar between the blocks of pyramids and to provide a smooth wall facing.
Gypsum concrete is lightweight and fire-resistant. A 1.5-inch slab of gypsum concrete weighs 13 pounds per square foot versus 18 pounds per square foot for regular concrete. [10] Even though gypsum concrete weighs less, it still has the same compressive strength as regular concrete, based on its application as underlayment or top coat flooring ...
