Novia STRP Pro Max AVCL is a premium specification, reinforced and foil laminated polythene membrane designed to function as a high-performance air and vapour control layer (AVCL). This product serves as a crucial air leakage barrier and vapour control membrane, effectively managing moisture vapour and reducing air leakage to improve the energy efficiency of buildings. Its robust construction makes it a superior choice for a wide range of applications.

Key Features 

  • Superior Construction: Novia STRP Promax is a reinforced and foil laminated polythene membrane.
  • High Vapour Resistance: As a highly effective vapour barrier, it offers excellent moisture vapour resistance, protecting the building's insulation and structure from condensation damage.
  • Airtightness: When installed correctly, it acts as an effective air leakage barrier, preventing heat loss and contributing to significant energy savings.
  • Reflective Surface: The aluminium foil surface provides reflective properties, enhancing the thermal performance of the insulation.

Applications:

  • Suitable for use in insulated wall, roof and floor applications, where there is a high risk of interstitial condensation occurring.
  • Particularly suitable for use in metal profile clad industrial buildings, and other commercial properties.
  • It can also be used in all insulated building constructions, such as flat roof applications ( internal installation only )

Installation tips:

All laps and edges should be fully sealed and taped. For AVCL, Manufacturer recommends using a minimum 30mm width Novia Double Sided Butyl Tape for all overlaps and around framework. To ensure a fully airtight seal, use a single sided tape, such a Novia Aluminium Foil Tape or Novia Metallised BOPP Tape to keep the overlap securely in place. Any mechanical fixings, must penetrate through the butyl tape to seal around any puncture created by the fixings. Where additional sealing is required, for example internal corners, floor sections or window reveals, the use of Novia AirSeal 310 FR should be considered.
