Plastic polyethylene vapor barrier Introduction (cited from wiki)
A vapor barrier (or vapour barrier) is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through the wall, floor, ceiling, or roof assemblies of buildings to prevent interstitial condensation and of packaging. Technically, many of these materials are only vapor retarders as they have varying degrees of permeability.
Materials have a moisture vapor transmission rate (MVTR) that is established by standard test methods. One common set of units is g/m²·day or g/100in²·day. Permeability can be reported in perms, a measure of the rate of transfer of water vapor through a material (1.0 US perm = 1.0 grain/square-foot·hour·inch of mercury ≈ 57 SI perm = 57 ng/s·m2·Pa). American building codes have classified vapor retarders as having a water vapor permeance of 1 perm or less when tested in accordance with the ASTM E96 desiccant, or dry cup method.[1] Vapor-retarding materials are generally categorized as:
Impermeable (≤1 US perm, or ≤57 SI perm) – such as polyethylene vapor barrier, asphalt-backed kraft paper, elastomeric coating, vapor-retarding paint, oil-based paints, vinyl wall coverings, extruded polystyrene, plywood, OSB.
Semi-permeable (1-10 US perm, or 57-570 SI perm) – such as unfaced expanded polystyrene, fiber-faced isocyanurate, heavy asphalt-impregnated building papers, some latex-based paints).
Permeable (>10 US perm, or >570 SI perm) – such as unpainted gypsum board and plaster, unfaced fiber glass insulation, cellulose insulation, unpainted stucco, cement sheathings, spunbonded polyolefin or some polymer-based exterior air barrier films.
Polyethylene vapor barrier: High density polyethylene vapor barrier
We are a well-known manufacturer of high density polyethylene water vapor barrier in China. Our product permeability is lower than ≤1.0×10-13 g•cm(cm2)•pa. So it can be categorized as impermeable vapor barrier. Its life span can last more than 70 years in this vapor barrier-system application. The width can reach more than 8m and the length can reach more than 800m.
Damp proofing is a very important part of keeping the building structure stabilization when designing the construction. Our flexible and good impermeable property of our polyethylene moisture barrier has been proven in a lot of vapor barrier projects for floor and walls again and again.
