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. EIFS has been in use since the 1960s in North America and was first used on masonry buildings.
Magnesium oxide wallboard (10 mm thickness) Magnesium oxide, more commonly called magnesia, is a 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.
Exterior wall studs are the vertical members to which the wall sheathing and cladding are attached. [14] They are supported on a bottom plate or foundation sill and in turn support the top plate. Studs usually consist of 1 + 1 ⁄ 2 -by- 3 + 1 ⁄ 2 -inch (38 mm × 89 mm) or 1 + 1 ⁄ 2 -by- 5 + 1 ⁄ 2 -inch (38 mm × 140 mm) lumber and are ...
The sheathing accepts all tensile forces while the core material has to withstand only some compressive as well as shear forces. In a SIP several components of conventional building, such as studs and joists, insulation, vapor barrier and air barrier can be combined.
A rainscreen is an exterior wall detail where the siding (wall cladding) stands off from the moisture-resistant surface of an air/water barrier applied to the sheathing to create a capillary break and to allow drainage and evaporation. The rainscreen is the cladding or siding itself [1] but the term rainscreen implies a system of building ...
An external wall insulation system (or EWIS) is a thermally insulated, protective, and decorative exterior cladding procedure involving the use of expanded polystyrene, mineral wool, polyurethane foam or phenolic foam, topped off with a reinforced cement based, mineral or synthetic finish and plaster.
The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. [citation needed] Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high by 48 inches long with a tongue-and-groove interlock, metal ties, and a waffle ...
A similar problem arose in the early 1980s, some 10 years before New Zealand and for similar reasons [34] in the Canadian province of British Columbia. It is commonly known in Canada as the Leaky condo crisis and has been an ongoing issue that is estimated to have caused $4 billion in damage since the 1980s.
