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.

Interior loadbearing walls are framed in the same way as exterior walls. Studs are usually 1 + 1 ⁄ 2 in × 3 + 1 ⁄ 2 in (38 mm × 89 mm) lumber spaced at 16 in (410 mm) on center. This spacing may be changed to 12 or 24 in (300 or 610 mm) depending on the loads supported and the type and thickness of the wall finish used. [12]
ICF walls have much lower rates of acoustic transmission. Standard thickness ICF walls have shown sound transmission coefficients (STC) between 46 and 72 compared to 36 for standard fiberglass insulation and drywall. The level of sound attenuation achieved is a function of wall thickness, mass, component materials and air tightness.
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.
Between the cladding and the wall there is a cavity where rain can run down. In the event of a fire this draws hot air up like a chimney, intensifies the fire, and spreads it to the top of the clad area. The fire can then get inside the building through open windows, for example to curtains blowing through windows. [1]
Today, the thinnest vinyl siding commonly used is .040", and is known as "builder's grade". Vinyl product can vary in thickness even within one manufacturer up to .010" of thickness through varying product lines offered that range from basic to premium-grade products.
Various sized cuts of 1 ⁄ 2 in (13 mm) drywall with tools for maintenance and installation . Drywall (also called plasterboard, dry lining, [1] wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of ...
To determine the total R-value of a wall, scale R 0 by the thickness of the wall in inches. The thermal resistance of adobe is also stated as an R-value for a 10-inch (25 cm) wall R 0 =4.1 hr ft 2 °F/Btu. [ 19 ]
