Reflex Insulation™ Fire Rated XHD Sarking
Reflective Extra Heavy Duty Sarking & Wall Wrap Membrane for use in Non-Combustible Construction
Reflex Insulation™ FR XHD is an Extra Heavy Duty multipurpose sarking and wall wrap designed for use in roof and wall systems. One side consists of a highly reflective foil, and the overall product is rated Extra Heavy Duty, meaning it is strong and tear resistant due to the multi layer structure.
Reflex Insulation™ FR XHD meets the requirements of NCC2019 Volume 1 Section C1.9 (e)(vi) and Volume 2 Section 3.7.1.1, as well as NCC 2016 Vol.1 C1.9(e) (vi).
Classified as High Water Barrier and a Class 2 Vapour Barrier, Reflex Insulation™ FR XHD acts as a barrier to radiant heat, moisture ingress, draughts and dust penetration.
Product Advantages
- Suitable for use where sarking-type materials are specified in non-combustible applications in accordance with the NCC
- Low flammability and suitable for use in bushfire zones BAL 12.5 to BAL FZ
- Highly Reflective single sided aluminium
- Water Barrier and Air Barrier

Installation Instructions
Reflex Insulation™ FR XHD Sarking should be installed in accordance with AS/NZS 4200.2 Pliable Building Membranes and Underlays, Part 2: Installation Requirements.
GENERAL
Reflex Insulation™ MD Wall Wrap should be installed horizontally with the printed side facing outward. Fix the product to all framing members, as a continuous membrane, and ensuring any damage or tears to the membrane are repaired.
Fixings should be galvanised clouts or staples for timber frames, and button head or tek screws for steel frames. In high wind areas, it is recommended to install using flat punched multi-point fasteners or cap screws.
When installing Reflex Insulation™ MD Wall Wrap, line up bottom of the roll covering the base of the timber bottom plate, ensure the product is level.
Horizontal, vertical and end overlaps must be 150 mm, with top layers of the membrane overlapping the outside of the lower layers to prevent water ingress.
Continue until the top of the wall frame is covered, and seal the membrane with tape to the top plate.
At windows or openings, Reflex Insulation™ MD Wall Wrap must be neatly cut, sealed and flashed at all sides to achieve its desired function and facilitate proper drainage to the building flashing. Ensure the membrane diverts water away from the opening.
External cladding should be installed without delay so as not to prolong direct exposure to UV light and other elements.
