VERSO REFLEX PLUS - REFLECTIVE VAPOUR BARRIER 1.5m x 50m (75m2)
Reflective Vapour Barrier: High-performance vapour control membrane with infrared reflective properties to reduce heat transfer from exterior steel surfaces.
NZ Fire Compliance: Flammability Index of 1, making it safe to be left exposed to the building interior.
High Vapour Resistance: Sd value of 8 m reliably seals internal moisture out of wall and roof cavities.
Extra High Wind Zone Rating: Suitable for residential, commercial, and industrial buildings in all NZS 3604 wind zones up to Extra High.
Timber & Steel Framing Suitable: Compatible with timber and steel-framed structures, unaffected by LOSP timber treatments.
1.5m x 50m Roll Format: Convenient unfolded 75m² roll format for efficient job-site installation and coverage.
15-Year Code Durability: Meets NZBC Clause B2 Durability requirements when installed in accordance with manufacturer technical literature.

Verso Reflex Plus Reflective Vapour Barrier (1.5m x 50m / 75m²) is a high-performance vapour control layer and reflective barrier imported and supplied throughout New Zealand exclusively by EBuilt Ltd (EProducts NZ Ltd).
Engineered and manufactured in Bielsko-Biała, Poland, by mdm NT—one of Europe’s premier manufacturers of technical building membranes—Verso Reflex Plus represents advanced building envelope technology. Produced under a sustainable zero-waste philosophy that recycles post-production waste to eliminate atmospheric factory emissions, Verso Reflex Plus is designed for New Zealand residential, commercial, and industrial constructions requiring superior internal vapour control and thermal radiation reflection.
Advanced Technical Quality & Material Construction
Verso Reflex Plus combines non-permeable membrane performance with heat-reflective surface properties:
Reflective Functional Surface: Engineered with a specialized reflective coating capable of reflecting infrared radiation, reducing heat transfer from exterior metal roof and wall claddings into the building interior.
Vapour Barrier Core: Formulated as a non-permeable, non-absorbent barrier that effectively blocks internal water vapour diffusion into roof and wall cavities.
Physical Profile: Supplied in unfolded 1.5m x 50m rolls covering 75m², with a nominal mass of 77 g/m² (+/- 10 g/m²) and a thickness of 0.50 mm (+/- 0.1 mm). It provides high mechanical integrity with maximum tensile force (>= 130 N/50mm machine direction / >= 90 N/50mm cross direction) and nail-shank tear resistance (>= 65 N machine direction / >= 65 N cross direction).
Core Performance Benefits
Effective Vapour Control & Moisture Prevention: Features a high water vapour resistance (Sd value of 8 m and vapour resistance of 0.74 x 10^11 (m² x s x Pa)/kg), effectively preventing internal humidity and moisture-laden air from penetrating into roof and wall construction assemblies.
Infrared Heat Reflection: Reflects radiant heat from external steel surfaces, helping moderate interior building temperatures and improving overall thermal efficiency in commercial, industrial, and residential structures.
High Fire Safety Rating (Interior Exposed Use): Tested to achieve a New Zealand Flammability Index of 1, allowing it to be safely left exposed to the interior of a building without requiring covering linings.
All Wind Zones Coverage: Suitable for use in all NZS 3604 Building Wind Zones up to and including Extra High when installed in accordance with system design guidelines.
Framing & Timber Treatment Compatibility: Compatible with both timber framing and light steel framing systems. Completely unaffected by LOSP-treated timber once solvent chemicals have flashed off (minimum 7 days flash-off period recommended).
Roof & Wall Cladding Integration: Designed for use under profiled metal roof and wall claddings where adequate internal ventilation and condensation control are provided. Can be laid either side up or used in direct contact with metal claddings following metal roofing code guidelines.
