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 ...
Fireproofing is rendering something (structures, materials, etc.) resistant to fire, or incombustible; or material for use in making anything fire-proof. [1] It is a passive fire protection measure. "Fireproof" or "fireproofing" can be used as a noun, verb or adjective; it may be hyphenated ("fire-proof").
A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail other criteria, involving evidence of functionality or fitness for purpose.
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat . An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
Cement bonded particle boards have treated wood flakes as reinforcement, whereas cement fibre boards have cellulose fibre, which is a plant extract as reinforcement. Cement acts as binder in both the cases. The fire resistance properties of cement bonded blue particle boards and cement fibre boards are the same.
A firestop or fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fire-resistance rating of a wall or floor assembly intended to impede the spread of fire and smoke. [1]
6-mil (0.15 mm) polyethylene plastic sheet as vapour barrier between insulation and gypsum board Glass wool pipe insulation covering a steel pipe as it penetrates a mock-up concrete slab whose opening will be firestopped.
Non-hazardous. Not restricted by depth of application. Fire resistant – flame spread 5, smoke spread 0 (ASTM-E-84) – will not smoke at all upon direct contact with flame and is a two-hour firewall at a 3.5 in (89 mm), or normal 2 in × 4 in (51 mm × 102 mm) stud wall, application per ASTM E-199.
