A water vapor barrier material for a building structure includes a base entangled net material and a composite nonwoven. The composite nonwoven includes a film layer with a nonwoven layer on each side of the film layer. The film layer has a water vapor transmission rate of less than 10.0 ...
Vapor barriers can’t be used alone in a wall assembly. An air gap along with the barrier is crucial. When warm air passes through walls, the moisture condenses out of it. This means that a vapor barrier needs to be placed on the warm side of the insulation to stop warm, moist air ...
FLORPRUFE® 120 is a high performance vapor barrier with GCP’s Advanced Bond Technology™ that forms a unique seal to the underside of concrete floor slabs. Forms a powerful integral seal to the underside of concrete slabs Protects valuable floor finishes ...
The standards specify placing a 6-mil polyethylene vapor retarder on top of a 4-inch layer of clean, coarse gravel below the foundation. The barrier also prevents the concrete from clogging the gravel layer during the slab pour. In addition, the ASTM E 1745-09 (Standard Specification for ...
Why a House Needs an Air Barrier An effective air barrier regulates the indoor climate by preventing the transfer of air (and the moisture attached to it) between the exterior and interior of a home. An air barrier must also stand up to the air pressure differences acting on them. They st...
on the interior side of the vapor barrier as a result of installing all of the thermal insulation on the exterior side of the vapor barrier (which is also the drainage plane and air barrier in this assembly). In hot climates any moisture that condenses on the exterior side of the vapor ...
