A vapor barrier on the warm side of the envelope must be combined with a venting path on the cold side of the insulation. This is because no vapor barrier is perfect, and because water may get into the structure, typically from rain. In general, the better the vapor barrier and the drier the conditions, the less venting is required. [7]
Visqueen is used as a condensation barrier inside walls when installing HVAC systems. It is also used as a ground cover in the crawl space of home foundations as a vapor barrier . [ 3 ] The use of Visqueen underneath a basement is to prevent water infiltration from water present in the ground that would pass through the concrete or dirt floor ...
A crawl space or crawlspace is an unoccupied, unfinished, narrow space within a building, between the ground and the first (or ground) floor. The crawl space is so named because there is typically only enough room to crawl rather than stand; anything larger than about 1 to 1.5 metres (3 ft 3 in to 4 ft 11 in) and beneath the ground floor would ...
Radiant barrier materials must have low emissivity (usually 0.1 or less) at the wavelengths at which they are expected to function. For typical building materials, the wavelengths are in the mid- and long-infrared spectrum, in the range of 3-15 micrometres. [citation needed] Radiant barriers may or may not exhibit high visual reflectivity.
Housewrap functions as a weather-resistant barrier, preventing rain or other forms of moisture from getting into the wall assembly while allowing water vapor to pass to the exterior. If moisture from either direction is allowed to build up within stud or cavity walls, mold and rot can set in and fiberglass or cellulose insulation will lose its ...
It's a mildly abrasive cleaner, so it's ideal for tackling those hard-to-tackle stains on tough materials like saucepans, cook tops, sinks, uPVC, barbecues, ceramic tiles, glass, garden furniture ...
The Saskatchewan Conservation House (211 Rink Ave, Regina, Saskatchewan, Canada [1]) is an early exemplar of energy-efficient building construction that introduced best practices for addressing air leakage in houses. [2] It was designed in response to the energy crisis of the 1970s at the request of the Government of Saskatchewan.
