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]
In 2024, Alaska Gear Company announced that it had redesigned the original Extreme Cold Weather Vapor Barrier Boots and simply named them Bunny Boots. The Alaska Gear Company Bunny Boots have a taller shank and no air valve. Previously, they were only manufactured for the military but now the public can also buy a new pair. [1] [3]
Concrete normally allows moisture to pass through so a vertical vapor barrier is needed. Barriers may be a coating or membrane applied to the exterior of the concrete. The coating may be asphalt, asphalt emulsion, a thinned asphalt called cutback asphalt, or an elastomer. [9] Membranes are rubberized asphalt or EPDM rubber. Rubberized products ...
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 ...
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 ...
Open-cell foam is porous, allowing water vapor and liquid water to penetrate the insulation. Closed-cell foam is non-porous, and not moisture-penetrable, thereby effectively forming a semi-permeable vapor barrier. (N.B., vapor barriers are usually required by the Building Codes, regardless of the type of insulation used.
A vapor barrier liner (VBL) is special type of liner that blocks the sleeper's moisture from reaching the bag, thus stopping evaporative heat loss. Usually a sleeping bag liner is used inside a VBL. Sleeping bag liners are issued as basic kit by various militaries including the US and British armed forces. [4]
Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers. There are many industries where moisture control is critical.
