Overview

Heavy Duty reflective sarking and wall wrap in one product.

ShieldFlex® HD is a flexible heavy duty wall wrap and roof sarking, that is a Class 2 Vapour Barrier and highly resistant to water transfer. Manufactured with a highly reflective aluminium foil on one side and laminated using a fire-resistant polymer adhesive to a woven polymer and UV-stabilised polymer film, ShieldFlex® HD is perfectly suited for both commercial and residential buildings for a second layer of protection against moisture, wind and dust while minimising condensation risk.

The all-rounder: rated Heavy Duty for roof sarking and wall wrap alike, with a reflective foil face and a woven core that resists tearing on a windy Perth roof. Class 2 vapour barrier, so it stops vapour rather than letting it through.

Product advantages

  • Class 2 Vapour Barrier and a Water Barrier in compliance with AS/NZS 4200.1.
  • Achieves low flammability results when tested to AS/NZS 1530.2.
  • Suitable for bushfire-prone areas and use in construction requirements with BALs of LOW – FZ.
  • UV resistant and extremely durable.

Applications

ShieldFlex® HD is designed for use in residential and commercial roofs in all Australian Climate Zones, and behind wall systems in Australian Climate Zone 1. ShieldFlex® HD may also be used as a facing foil for bulk insulation blanket, providing the temperatures when processing the product do not exceed 80ºC.
