Cladding in construction is material applied over another to provide a skin or layer and used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings. Between the cladding and the wall there is a cavity where rain can run down.
In the United States, the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat.
Metal facade cladding at a gymnasium – built 2023. Rainscreen cladding is a kind of double-wall construction that utilizes a surface to help keep the rain out, as well as an inner layer to offer thermal insulation, prevent excessive air leakage and carry wind loading. The surface breathes just like a skin as the inner layer reduces energy losses.
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.
Siding or wall cladding is the protective material attached to the exterior side of a wall of a house or other building. Along with the roof, it forms the first line of defense against the elements, most importantly sun, rain/snow, heat and cold, thus creating a stable, more comfortable environment on the interior side.
Wall cladding fastened to the girt, or a discrete bracing system which includes the girt, can provide shear resistance, in the plane of the wall, along the length of the primary member. Since the girts are normally fastened to, or near, the exterior flange of a column, stability braces may be installed at a girt to resist rotation of the ...
The curtain wall itself, however, is not ordinarily required to have a rating. This causes a quandary as compartmentalization (fire protection) is typically based upon closed compartments to avoid fire and smoke migrations beyond each engaged compartment. A curtain wall by its very nature prevents the completion of the compartment (or envelope).
A cavity wall is a type of wall that has an airspace between the outer face and the inner, usually structural, construction. [1] The skins typically are masonry , such as brick or cinder block . Masonry is an absorbent material that can retain rainwater or condensation.
