Installation Tutorial

In Europe plasterboard is manufactured in metric sizes, with the common sizes being corollaries of old imperial sizes.

Most plasterboard is made in 120 cm wide sheets, though 90 cm and 60 cm wide sheets are also made. 120 cm wide plasterboard is most commonly made in 240 cm lengths, though 250, 260, 270, 280, 300 cm and even longer (if ordered) are commonly available.

Commonly used thicknesses of plasterboard available are 12.5 mm (modern equivalent of half an inch), typically used for walls, and 9.5mm typically for ceilings where no specific period of fire resistance is required, 13mm hard/durable type and 15mm Fireboards are commonly available, as are 6.5mm thick "Rehab" type sheets.

Plasterboard is commonly made with one of three different edge treatments—tapered edge, where the long edges of the board are tapered with a wide bevel at the front to allow for jointing materials to be finished flush with the main board face, plain edge, used where the whole surface will receive a thin coating (skim coat) of finishing plaster, and finally bevelled on all four sides, used in products specialised for roofing. However four side chamfered drywall is not currently offered by major UK manufacturers for general use.

Manufacture

A wallboard panel is made of a paper liner wrapped around an inner core made primarily from gypsum plaster. The raw gypsum, CaSO₄·2 H₂O, (mined or obtained from flue-gas desulfurization(FGD)) must be calcined before use to produce the hemihydrate of calcium sulfate (CaSO₄·½ H₂O). This is done in kettle or flash calciners, typically using natural gas today. The plaster is mixed with fiber (typically paper and/or fiberglass), plasticizer, foaming agent, finely ground gypsum crystal as an accelerator, EDTA, starch or other chelate as a retarder, various additives that may increase mildew and/or fire resistance (fiberglass or vermiculite), wax emulsion or silanes for lower water absorption and water. This is then formed by sandwiching a core of wet gypsum between two sheets of heavy paper or fiberglass mats. When the core sets and is dried in a large drying chamber, the sandwich becomes rigid and strong enough for use as a building material.

Drying chambers typically use natural gas today. To dry 1 MSF ( 1,000 square feet (93 m²) ) of wallboard, between 1.75 and 2.49 million BTU is required. Organic dispersants/plasticisers are used mainly to reduce the amount of water, hence reduce the eventual drying time, needed to produce gypsum slurry flow during wallboard manufacture.

History of Drywall

In 1916 United States Gypsum Company, an American company produced the first gypsum board, which basically treated gypsum panels squeezed between paper and called Sheetrock (sheet rock).

This new system allowed be assembled quickly on a frame and the seams between the plates could plaster to make a unified wall, eliminating the need for wood strip, the multiple layers of plaster, and days of drying (hence its name generic "drywall" or dry wall, for he had the advantage of working with dry plaster.

Led by World War II came an urgent need for military structures, from barracks to entire databases.
Facing a shortage of labor and material, there is a great need to find faster and more effective ways of building.

The solution to this was the system of gypsum "drywall" for its fast and flexible commissioning work, his uniform and smooth surface achieved, which only needed a thin layer of plaster to the joints.

During the postwar period there was a construction boom in the U.S. that meant the consolidation of this practical, fast and efficient construction system that was introduced in most American homes and buildings

This construction system began to expand with marked success in the world. Join to Chile in the 50s and late 70s in Argentina, Brazil and Venezuela.

In Colombia was first used during the eighties, then to the mid-nineties and took a relative importance in the last decade has become massive use becoming one of the most promising building systems and favorable for any type of building for its advantages comparisons, however, are just entering Colombia culture Drywall system, it is estimated that while in USA per capita consumption is 16m ² Drywall, arrived in the country just 0.33m ² in 2009.

DRYWALL IS

It is a building of great growth in Colombia that is used worldwide, in the country is also known by the name of Lightweight Construction and its main characteristic is that its construction process uses no water, making it very agile Drywall and limpio.El system is to form a structure in galvanized steel that is attached to the plates or concrete walls of buildings and which are screwed plasterboard or fiber cement. The finishing process is performed by placing fiberglass tape or paper (as applicable) in the joints of the sheets and applying a special putty finally sanded surfaces and are given the final latex paint finish or otherwise .
