Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that have been stacked and glued together. It is an engineered wood from the family of manufactured boards, which include plywood, medium-density fibreboard (MDF), oriented strand board (OSB), and particle board (or chipboard).
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.
standard sizes[edit] "Plywood can be sold in sizes up to 6 ft * 25 ft and by the scarf jointing of small sheets up to 6 ft *40 ft, however 6 ft*3 ft is the most common size." I've never even heard of 6 ft x 3 ft sheets. In the USA, 4 ft (102 mm) x 8 ft (203 mm) is the standard size of plywood with longer sheets available on special order.
Fire-resistance rating. 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 blocking is most critical in balloon framing, where a cavity may traverse multiple floors. More modern methods of platform-framing provide inherent fireblocking in most cases, since the cavity is interrupted at every floor level by top and bottom sill plates. Fire blocking may also serve as bridging between framing elements, stiffening ...
Cross-laminated timber (CLT) is a subcategory of engineered wood [ 1 ] panel product made from gluing together at least three layers [ 2 ] of solid-sawn lumber (i.e. lumber cut from a single log). [ 3 ] Each layer of boards is usually oriented perpendicular to adjacent layers and glued on the wide faces of each board, usually in a symmetric way ...
An engineered wood joist, more commonly known as an I-joist, is a product designed to eliminate problems that occur with conventional wood joists. Invented in 1969, the I-joist is an engineered wood product that has great strength in relation to its size and weight. The biggest notable difference from dimensional lumber is that the I-joist ...
NFPA 704 safety squares on containers of ethyl alcohol and acetone. " NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response " is a standard maintained by the U.S. -based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, [1] and revised several times since then, it ...
