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
Installation guidelines can be found on the product datasheets using the links to the left. To install the membranes, we recommend using the Novia double tape system.
Our Novia® Double-Sided Butyl Tape is used on the laps and edges of the membrane, with one of our Novia® Single-Sided Lap Tapes (SSLT) used to complete the lap seal. For difficult areas to seal with tapes, or for additional support in certain applications, Novia® AirSeal 310 FR is available.
