oriented strand board osb is a wood structural panel manufactured from rectangular-shaped strands of wood that are oriented lengthwise and then arranged in layers, laid up into mats, and bonded together with moisture-resistant, heat-cured adhesives. the individual layers can be cross-oriented to provide strength and stiffness to the panel.
cemesto is a sturdy, light-weight, waterproof and fire-resistant composite building material made from a core of sugar cane fiber insulating board surfaced on both sides with asbestos and cement. its name is a portmanteau word combining 'cem' from 'cement' and 'esto' from 'asbestos.' a type of prefabricated home using this material came to be called cemestos.
a cement board is a combination of cement and reinforcing fibers formed into 3 by 5 feet sheets, 1⁄4 to 1⁄2 inch thick that are typically used as a tile backing board. cement board can be nailed or screwed to wood or steel studs to create a substrate for vertical tile and attached horizontally to plywood for tile floors, kitchen counters and backsplashes. it can be used on the exterior of buildings as a base for exterior plaster systems and sometimes as the finish system itself. cement .
exterior insulation and finish system eifs is a general class of non-load bearing building cladding systems that provides exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system.in europe, systems similar to eifs are known as external wall insulation system ewis and external thermal insulation cladding system etics .
fiber cement board may come pre-painted or pre-stained or can be done so after its installation. fiber cement siding has several benefits since it is resistant to termites, does not rot, is impact resistant, and has fireproof properties.
moisture resistant is typically green fire retardant mdf is typically red or blue although similar manufacturing processes are used in making all types of fibreboard, mdf has a typical density of 600–800 kg/m³ or 0.022–0.029 lb/in 3 , in contrast to particle board 160–450 kg/m³ and to high-density fibreboard 600–1,450 kg/m³ .
plywood, a wood structural panel, is sometimes called the original engineered wood product. plywood is manufactured from sheets of cross-laminated veneer and bonded under heat and pressure with durable, moisture-resistant adhesives. by alternating the grain direction of the veneers from layer to layer, or “cross-orienting”, panel strength .
panel production involves other chemicals including wax, dyes, wetting agents and release agents, to aid processing or make the final product resistant to water, fire or insects. after the particles pass through a mist of resin sufficient to coat all surfaces, they are layered into a continuous carpet.
gypsum block is a massive lightweight building material composed of solid gypsum, for building and erecting lightweight, fire-resistant, non-load bearing interior walls, partition walls, cavity walls, skin walls, and pillar casing indoors. gypsum blocks are composed of gypsum, plaster, water and in some cases additives like vegetable or wood fiber for greater strength.
masonite is used extensively in the construction of sets for theater, film and television. it is especially common in theaters as the stage floor, painted matte black. it is considered one of the best materials for making a musical wobble board. masonite 4-by-8-foot 1.2 by 2.4 m panels are sometimes sawn into 4-inch 100 mm by 8-foot strips .
bituminous waterproofing systems are designed to protect residential and commercial buildings.bitumen asphalt or coal-tar pitch is a mixed substance made up of organic liquids that are highly sticky, viscous, and waterproof. these systems are sometimes used to construct roofs, in the form of roofing felt or roll roofing products.
waterboarding is a form of torture in which water is poured over a cloth covering the face and breathing passages of an immobilized captive, causing the person to experience drowning.in the most common method of waterboarding, the captive's face is covered with cloth or some other thin material and immobilized on his/her back at an incline of 10 to 20 degrees.
rigid panel insulation, also referred to as continuous insulation, can be made from foam plastics such as polyurethane pur , polyisocyanurate pir , and polystyrene, or from fibrous materials such as fiberglass, rock and slag wool.rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus reducing thermal bridging
magnesium oxide wallboard 10 mm thickness magnesium oxide , more commonly called magnesia , is a versatile mineral that when used as part of a cement mixture and cast into thin cement panels under proper curing procedures and practices can be used in residential and commercial building construction .
