front 7 Fire door | back 7 Specially constructed, tested, and approved fire-rated door assembly designed and installed to prevent fire spread by automatically closing and covering a doorway in a fire wall to block the spread of fire through door opening. |
front 8 Fire-resistance rating | back 8 Rating assigned to a material or assembly after standardized testing by an independent testing organization; identifies the amount of time a material or assembly will resist a typical fire, as measured on a standard time-temp curve |
front 9 Fire-stop | back 9 Solid materials such as wood blocks, used to prevent or limit the vertical and horizontal spread of fire and the products of combustion in hollow walls or floors, above false ceilings, in penetrations for plumbing or electrical installations, in penetrations of a fire-rated assembly, or in cocklofts and crawl spaces |
front 10 Fire-wall | back 10 fire-rated wall with a specific degree of fire resistance, built of fire-resistive materials and usually extending from the foundation up to and through the roof of a building; designed to limit the spread of a fire within a structure or between adjacent structures |
front 11 Glue-laminated beam | back 11 Wooden structural member composed of many relatively short pieces of lumber glued and laminated together under pressure to form a long, strong beam |
front 12 Gusset plate | back 12 Metal or wooden plates used to connect and strengthen the joints of two or more separate components into a load-bearing unit |
front 13 Hybrid modular structure | back 13 Structure consisting of the elements of both modular design and panelized construction. |
front 14 Load-bearing wall | back 14 wall of a building that by design carries at least some part of the structural load of the building in the direction of the ground or base |
front 15 Manufactured home | back 15 four major components: the chassis and the floor, wall, and roof systems. basically the frame construction |
front 16 means of egress | back 16 Continuous and unobstructed way of exit travel from any point in a structure to a public way, consisting of the tree distinct parts: exit access, exit and exit discharge |
front 17 Modular home | back 17 Structure assembled at the factory in two or more sections. connected when the pieces are delivered on site |
front 18 Oriented strand board(OSB) | back 18 A wooden structural panel formed by gluing and compressing wood strands together under pressure. |
front 19 Panelized home | back 19 Home assembled on site consisting of construction panels made of foam insulation sandwiched between sheets of plywood. Assembled on site |
front 20 Parallel chord truss | back 20 A truss constructed with the top and bottom chords parallel. these are used as floor joists in multistory buildings and as ceiling joists in buildings with flat roofs |
front 21 Parapet | back 21 Portion of the exterior walls of a building that extends above the roof. A low wall at the edge of a roof |
front 22 Photovoltaic roof | back 22 Roof that features a solar panel array that is designed to provide electricity to the structure. |
front 23 Photovoltaic (PV) system | back 23 an arrangement of components that convey electrical power to an energy system by converting solar energy into direct current (DC) electricity |
front 24 Protected stair | back 24 fire-rated enclosure construction; intended to protect occupants as they make their way through through |
front 25 Purlin | back 25 Horizontal member between trusses that support the roof |
front 26 Ridge | back 26 Horizontal line at the junction of the top edges of two sloping roof surfaces |
front 27 Type 1 construction | back 27 Construction type in which structural members, including walls, columns, beams, floors, and roofs, are made of noncombustible or limited combustible materials and have a specified degree of fire resistance. |
front 28 Type 2 construction | back 28 Construction type that is similar type 1, but the fire resistance is lower |
front 29 Type 3 construction | back 29 Exterior walls and structural members are made of noncombustible or limited combustible materials, but interior structural members, including walls, columns, beams, floor and roofs are completely or partially constructed of wood. |
front 30 Type 4 construction | back 30 Heavy timber construction in which interior and exterior walls and their associated structural members are made of noncombustible or limited combustible material; interior structural framing consists of heavy timber with minimum dimensions larger than those used in type 3. |
front 31 type 5 construction | back 31 exterior walls, bearing walls, floors, roofs, and supports are made completely or partially of wood or other approved materials of smaller dimensions than those used in type 4 |
