the exterior walls of a house have several functions. not only do they define the shape of a house, they also support the floors, walls, and roof. equally important is their role in separating the houses interior from the outdoors, and to do this effectively they have to block the weather with systems that insulate, shed water, and repel moisture and air infiltration.
exterior gypsum sheathing. other types of exterior gypsum sheathing are made with a thin fiberglass mat facing, which resists water and board deterioration better than treated paper faces. exterior gypsum sheathing is available with a fire-rated type x core which is described in the fire-rated products section below.
the walls inside manufactured homes cover the exterior structure of the home and hold the exterior insulation in place. the wall studs also provide support for the drywall, windows and roof. the most common material is a 2 x 4 for interior and exterior walls, but manufacturers can use 2 x 6s, which increases the exterior cavity, making room for higher insulation levels. walls also hide plumbing and wiring.
the structure of your exterior walls will depend on the method of construction that you or a crew decides to use for your house. the different types of structures include wood frames, steel frames, precast concrete, poured-in-place concrete, structural insulated panels sips , or insulated concrete forms icfs .
1405.3.1 exterior wall pockets. in exterior walls of build- ings or structures, wall pockets or crevices in which mois- ture can accumulateshall be avoided or protected with caps or drips, or other approved means shall be provided to pre- vent water damage. 1405.3.2 masonry.
in addition to the existing three main types of decorative wall panels, there are also designs for the construction of interior walls and different partitions. these include both of the concrete panel and a sandwich panel for modular houses, in the form of ready-made walls with a heater and a moisture and vapor barrier inside.
ceiling and wall covering materials using plaster, drywall / gypsum board, or stucco. horsehair mixed with plaster or cement for building exterior wall covering plaster of paris applied in at least two layers,a rough brown or scratch coat and a smooth white plaster top coat over hand split or sawn wood lath.
type iii is driving me crazy on an inspection this afternoon: steel columns and beams with girts on exterior side. the exterior side of the girts is metal panel siding with vinyl faced insulation and the interior side of girts is faced with osb plywood to a height of 10 ft. where does the 'exterior wall' begin and where does it end?

traditional type iii is brick load bearing exterior walls with frame interior members and roof. the advantage of this construction over v is the prevention of spread of fire from building to building.
building elements: the exterior bearing walls and load-bearing portions of exterior walls must be of noncombustible materials or of masonry, but exterior nonbearing walls and wall panels may be slow-burning, combustible, or with no fire-resistance rating. walls: solid masonry, including reinforced concrete not less than four inches thick
major wall types: institutional, commercial, and residential. rock or concrete masonry provides the structure, with water, air, vapor, and thermal control layers outside that surface. it has a gypsum board interior and dries from the control layers out and from the control layers in, giving it moisture adaption capabilities to exist in multiple
in addition to the requirement for exterior wall framing to be non-combustible or fire-retardant-treated wood, the exterior walls typically need to have a 2-hour fire-resistance rating. again, the code is not clear on what happens at the wall to floor intersections.
the required fire-resistance rating of exterior walls with a fire separation distance of less than or equal to 10 feet 3048 mm shall be rated for exposure to fire from both sides. exterior bearing walls with fire separation > 10' : 5/8' type 'x' on 2 x framing at 16' o.c. per ibc section 721. 1 hr interior bearing walls are 1-hr, not 2-hr.
architectural graphics 101 wall types. if we look at the simplest of walls in plan view, you might see that wall delineated as two lines, each representing the outermost face of that wall, when in fact, that wall was a layer of drywall, interior structural element wood or metal studs , and another layer of drywall.
figure 1: the perfect wallin concept the perfect wall has the rainwater control layer, the air control layer, the vapor control layer and the thermal control layer on the exterior of the structure. the claddings function is principally to act a an ultra-violet screen.
therefore, this wall uses control layers on the outside of its structure. to deal with steel framing, designers can insulate the wall on the exterior with continuous insulation to help prevent heat and cold from reaching the framing. insulation added to a steel wall cavity reduces sound transfer. the residential wall. the final variation of the
when editing the structure of a vertically compound wall, use the modify tool on the edit assembly dialog to perform several functions, including changing the wall thickness, extending layers, and constraining a region. to change a vertically compound wall, in the edit assembly dialog, click modify.
1. load bearing wall. it carries loads imposed on it from beams and slabs above including its own weight and transfer it to the foundation. these walls supports structural members such as beams, slabs and walls on above floors above. it can be exterior wall or interior wall. it braces from the roof to the floor. types of load bearing wall
the walls inside manufactured homes cover the exterior structure of the home and hold the exterior insulation in place. the wall studs also provide support for the drywall, windows and roof. the most common material is a 2 x 4 for interior and exterior walls, but manufacturers can use 2 x 6s, which increases the exterior cavity, making room for
exterior wall composition. the exterior wall composition 10 is essentially a solid insulated concrete-steel panel assembled on site. firstly, the basic lattice framework of load bearing steel studs 11 is shipped to the site precut to the proper lengths and assembled on site by suitable means such as welding.
the method of making this exterior wall composition 10 does not require expert skills, uses known material and permits quick erection. to erect a building structure the floor slab is firstly poured with necessary services included therein. the exterior wall composition 10 is essentially a solid insulated concrete-steel panel assembled on site.
there are two types of sheathing: structural and nonstructural. structural sheathing. this type is integral to the houses framing. it ties together wall studs, contributing shear strength and rigidity and forming a solid nailing base for siding materials. most structural sheathings do not add much insulation value.
exterior insulation and finish system 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 and external thermal insulation cladding system. eifs has been in use since the 1960s in north america, first on masonry buildings, but since the 1990s the majority on wood framed buildings.
exterior doors generally are reinforced with steel for security, and have some type of insulation inside them to keep your home comfortable. flashing along walls in addition to the flashing around windows and doors, flashing is added at several other places along exterior walls to help direct water away from the home.
composition siding can be hardi-board but if it is older it may actually mean masonite or lp type siding-both of which are problematic and subject to class action lawsuits. they were like carboard and glue pressed together. once paint wore off, moisture could intrude and cause it to swell and fall apart. also pretty good termite bait.
