ProctorGeo Vap 120

Vapour Retarder and Convection Barrier

Product Overview

ProctorGeo Vap120 is a light duty vapour retarder and convection barrier. The high air & water vapour resistance of the two-layer polyolefin non-woven membrane resists the flow of vapour by both diffusion and air movement through wall, ceiling and floor assemblies thus helping protect the building fabric and insulation from condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance.

When installed as a continuous layer, ProctorGeo Vap120 will help form an airtight layer reducing the loss of heated air or cooled air from the building thus improving the energy efficiency of the building enclosure.

  • Testing to ASTM1530.2 has only been conducted on sections of material without integrated tape.
  • It should not be left exposed to UV for longer than 4 weeks.

Applications

Vapour retarders are typically used with sheet roof and wall claddings, in constructions located in cold climates, buildings with high internal humidity such as indoor swimming pools and museums, air-conditioned buildings located in hot and humid climates and refrigerated buildings such as cold stores and ice rinks.

Vapour retarders should not be used on the exterior side of insulation in cold and temperate climates as a sarking where there is a risk that condensation will form on the interior face of the retarder.

Integrated Tape

To improve the integrity of installation, ProctorVap 120 is supplied with a factory applied integrated tape on both the outer face of the lower course and rear face of the upper membrane.

Durability

Ensure that ProctorGeo Vap120 is covered as soon as possible, and not left exposed to UV for longer than 4 weeks. ProctorGeo Vap120 is not to be used in installations where it could be exposed to long term UV radiation.

Benefits
