Verified by manufacturer 24 hours ago
500 gauge/ 125 micron virgin grade polythene vapour control layer.
Application
For use as an air and vapour control layer (AVCL). Suitable for all SFS light steel frame, timber frame and concrete frame insulated wall constructions. Also used in insulated pitched roofs and floor applications. Novia manufacture different gauges of virgin grade VCL to ensure the correct products meets the requirements of the building. Take a look at www.novia.co.uk for more details and our other vapour control layer and air tightness membrane options available to you.
Description
A traditional, single-ply, virgin grade blown polythene material. Its 2.7 m width makes it particularly suitable for use in residential SFS and timber frame applications. To provide an airtight seal, it must be installed in conjunction with the Novia two-tape sealing system.
Features and benefits:
- Low cost solution.
- Air leakage barrier and vapour control layer (AVCL).
- Supplied centre-folded in 2.7 m width, ideal for SFS and timber frames.
- Ideal for use with Novia breather membranes in insulated frame applications.
- Easy to install, translucent with a green tint.
- Virgin-grade, high-quality material.
- UKCA approved.
- Minimises interstitial condensation.
- Improves the insulation performance.
- Install with Novia two tape sealing system.
- Helps buildings meet BS 5250.
- Complies with BS EN 13984.
- If a fire rated VCL is required, please see Novia VC4000 FR.
Tape:
- For professional installation, all Novia® VCL products must be fully sealed to the structure using a Novia® double-sided butyl tape and metallised 'BOPP' overlap tape, or Novia foil overlap tape.
- Novia® 30 mm wide butyl tape and 60 mm metallised 'BOPP' tape must be used for all standard VCL installations.
- Novia AirSeal310 cartridge sealant should be used with Novia tapes when sealing against concrete surfaces.
