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 ...
A gypsum block is made of gypsum plaster and water. The manufacturing process [1] is automated at production plants where raw gypsum (CaSO 4 ·2H 2 O) is ground and dried, then heated to remove three-quarters of the bound water and thus transformed into calcium sulfate hemihydrate (CaSO 4 ·½H 2 O), also known as gypsum plaster, stucco, calcined gypsum or plaster of Paris.
Lath and plaster largely fell out of favour in the U.K. after the introduction of plasterboard in the 1930s. [2] In Canada and the United States, wood lath and plaster remained in use until the process was replaced by transitional methods followed by drywall (the North American term for plasterboard) in the mid-twentieth century.

A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction , refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials.
A typical installation of insulated glass windows with uPVC frames. Possibly the earliest use of double glazing was in Siberia, where it was observed by Henry Seebohm in 1877 as an established necessity in the Yeniseysk area where the bitterly cold winter temperatures regularly fall below -50° C, indicating how the concept may have started: [2]
The development of plasterboard (a sandwich of gypsum plaster between two sheets of paper) dates back to the late nineteenth century in the US. The first patent was granted in 1894 but it was not until an American, Frank Culver, persuaded his new employer, Thomas McGhie and Sons, to buy a plasterboard plant from the US that this new product was introduced to Britain.
A restored Westchester Deluxe (sans ceiling and roof) from Arlington, Virginia, was reassembled inside the Ohio History Connection [18] in Columbus, Ohio, in 2013. It had been partially assembled (no bedrooms) for a few months in the Museum of Modern Art (MoMA) in Manhattan. The house continues to be on display in Columbus through 2024 at least.
Overhead insulated cables are rarely used, usually for short distances (less than a kilometer). Insulated cables can be directly fastened to structures without insulating supports. An overhead line with bare conductors insulated by air is typically less costly than a cable with insulated conductors. A more common approach is "covered" line wire.
