Is block it a vapor barrier?
Permeability ratings of at least 5 perms (under the International Residential Code) or 10 perms (under the International Building Code) are required to be considered “vapor permeable.” BLOCK-IT* House Wrap has patented breathable barrier technology engineered to allow water vapor to escape from the wall cavity and to
Do house wraps need to breathe?
Housewraps provide a vapor-permeable layer that resists liquid water from the outside, while also allowing water vapor to escape the assembly, enabling the wall to “breathe” (for example, if water vapor is driven from the interior to the exterior during a heating season, the housewrap will allow the vapor to escape).
What is considered a vapor barrier?
A vapour barrier (sometimes referred to as vapour retarder) is typically a plastic or foil sheet used for damp proofing to prevent interstitial condensation from forming in various building assemblies such as walls, roofs, foundations and floors.
Is Tyvek house wrap good?
In separate ASTM E-283 testing (at 75PA or 1.57 PSF), Tyvek® HomeWrap® also showed superior performance in the area of air resistance. This is significant because preventing air infiltration in the wall cavity is a key factor in allowing insulation to perform to its installed R-value.
Does Tyvek need to be taped?
The house needs some airflow to avoid moisture build-up within the home. The manufacturer recommends only taping the Tyvek HomeWrap seams.
