Novia STRP ProMax Reinforced Air & Vapour Control Layer - 1.6m x 50m roll

Novia STRP ProMax is a premium reinforced Air & Vapour Control Layer (AVCL) designed to deliver exceptional vapour resistance, airtightness and long‑term durability in demanding building environments. It is a foil‑laminated, reinforced polythene membrane engineered for internal use across walls, roofs and floors, particularly where there is a high risk of interstitial condensation. STRP ProMax is built around a super‑tough reinforced polythene core with an aluminium foil laminate, giving it both high mechanical strength and excellent vapour‑control performance. It meets BS EN 13984 and carries UKCA marking, confirming compliance with recognised industry standards.

CHARACTERISTICS

• Premium reinforced foil‑laminated construction: Provides outstanding strength and durability for long‑term performance. 
• Excellent moisture vapour resistance: Ideal for build‑ups where interstitial condensation risk is high. 
• Airtight membrane: Helps reduce air leakage and improve overall energy efficiency. 
• Suitable for walls, roofs and floors: Versatile across a wide range of insulated constructions. 
• Reflective thermal benefit: When installed facing a 25 mm air gap, the reflective surface provides additional thermal performance. 
• Ideal for industrial and commercial buildings: Particularly suited to metal‑profile‑clad structures.

• Insulated wall systems
• Warm flat roof constructions
• Insulated floor build‑ups, where vapour control is essential
• General airtightness upgrades to reduce heat loss and improve building performance

• Meets BS EN 13984; UKCA marked
