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.
Knauf Insulation is an international company owned by the Knauf family and is an important manufacturer of insulation products in the US and Europe. [1] The company is a producer of insulation materials such as glass wool, stone wool, wood wool boards, EPS, XPS, as well as the Heradesign wood wool based acoustic ceiling systems.
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 ...
Knauf Group is a multinational, family-owned company based in Iphofen, Germany, well known for drywall gypsum boards, founded in 1932. The company is a producer of building materials and construction systems comprising construction materials for drywall construction, plasterboard, cement boards, mineral fibre acoustic boards, dry mortars with gypsum for internal plaster and cement-based ...
A vapor barrier on the warm side of the envelope must be combined with a venting path on the cold side of the insulation. This is because no vapor barrier is perfect, and because water may get into the structure, typically from rain. In general, the better the vapor barrier and the drier the conditions, the less venting is required. [7]
Drywall, also known as plasterboard, is a building material typically consisting of gypsum-based plaster extruded between two thick sheets of paper and kiln-dried.. Drywall was imported by the United States during the construction boom between 2004 and 2007, spurred by a shortage of American-made drywall due to the rebuilding demand of nine hurricanes that hit Florida from 2004 to 2005, and ...
Evaporative deposition: the material to be deposited is heated to a high vapor pressure by electrical resistance heating in "high" vacuum. [4] [5] Close-space sublimation, the material, and substrate are placed close to one another and radiatively heated. Pulsed laser deposition: a high-power laser ablates material from the target into a vapor.
Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers. There are many industries where moisture control is critical.
