Novia STRP ProMax AVCL
Our premium specification, reinforced aluminium foil vapour barrier
Product Overview
Novia® STRP ProMax is a premium specification, reinforced, foil laminated polythene membrane for use as an internal Air & Vapour Control Layer (AVCL). The material meets BS EN 13984 and is UKCA marked. Novia® STRP ProMax has excellent moisture vapour resistance and is suitable for use in insulated wall, floor or roof applications where there is a high risk of interstitial condensation occuring. It also minimises air leakage and energy heat losses, improving the long-term energy efficiency of constructions. Novia® STRP ProMax is 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). When installed with a 25mm air gap, the reflective face will provide an additional thermal benefit. Novia® STRP ProMax is reflective on one side, blue on the reverse, with no text or images.
Novia® STRP ProMax meets the requirements for UKCA marking, originally introduced under the 2013 Construction Products Regulations with CE marking. Under this European directive, all products covered by a current hEN (harmonised European Norm) must comply with the new standard. Third party accreditation is no longer sufficient. This has been adapted to UKCA following the UK departure from the EU.
Novia® STRP ProMax can be found on NBS Chorus and NBS Source software packages. Full information can be found for NBS specification with the table below. The links will open a pop up window with full specification information.

Installation Tips
All laps and edges should be fully sealed and taped. For air & vapour control layer installations, we recommend 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.
