LDPE VAPOR BARRIER

1. Introduction:

A vapour barrier is a membrane that restricts the migration of moisture by diffusion from an area of high humidity. A vapour barrier must be located near the warm side of walls and ceilings so that condensation in the cold region of the assembly does not occur.
JENNYEVER vapor barrier is made of LDPE and is a high performance underslab vapor retarder designed to tetard moisture migration through concrete slabs-on-grade. This product is made from state of the art polyethylene resins thatprovide superior physical and performance properties that far exceed ASTM E-1745 (Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill under Concrete Slabs) Class A, B, and C requirements. High tensile strength, unequaled puncture resistance, low moisture vapor permeability as well as resistance to decay make Vapor Block one of the most effective under-slab vapor retarders on the market today! Available in 150,250 and 380 micron thickness to best meet required performance.

The vapor barrier  impedes the transmission of water vapor from traveling upward through a concrete slab-on-grade or through a concrete wall when properly installed. It is extremely important to avoid puncturing a vapor retarder during installation to assureproper performance. The vapor barrier's puncture strength is second to none, withstanding even the most demanding installation conditions. The  vapor retarders protect your flooring and other moisture sensitive furnishings in your building ' s interior from moisture migration. It can also greatly reduce condensation, mold and degradation by controlling water vapor migration.

Specification thickness 0.10 mm -0.5mm     width 4 -14m       color: transparent, black and other custom colors

Ccustom sizes are available depending upon size and volume requirements. All rolls are folded and rolled on heavy-duty cores for ease in handling and installation.
