More Information – Sisalation® Multipurpose EHD (456) Roof Insulation

Sisalation® Multipurpose EHD (456) is a high-performance pliable building membrane designed specifically for metal roof applications in both residential and commercial buildings. Manufactured to meet the demands of Australia’s harsh climate zones, it plays a critical role in thermal efficiency, condensation management, and weather protection.

Sisalation® Multipurpose EHD (456) is manufactured in accordance with Australian standards, specifically in accordance with AS 3959-2009, ensuring compliance for bushfire-prone areas.

This product is part of a range of insulation products designed for Australian conditions.

What is Sisalation®?

Sisalation® is a reflective insulation foil that acts as an effective secondary skin when installed beneath metal roofs or wall cladding. Sisalation® features an anti-glare surface to improve safety and installation comfort. It assists in reflecting radiant heat, reducing heat transfer into the building, and supporting a more stable thermal comfort inside — whether you’re working on a large-scale commercial roof or a suburban home.

Designed for Metal Roofs and Sarking Use

In metal roof sarking applications, this foil insulation is typically installed adjacent to an air cavity, boosting the system’s overall total R value. Sisalation® can be used as a wall wrap or roof wrap to provide a protective barrier. This is especially beneficial in metal roof constructions, where air gaps and conductive surfaces require reliable insulation.

Key benefits for metal roofing projects include:

• Enhanced thermal performance

• Reduced moisture absorption

• Improved acoustic ambience in large internal spaces

• Helps to minimise draughts and dust penetration

• Effective in combination with bulk wall insulation for optimal performance

Protection in Bushfire Areas

Sisalation® Multipurpose EHD (456) is suitable for use in areas subject to Bushfire Attack Level (BAL) regulations, including those with a BAL of 0–40. It meets requirements for flame resistance, helping to reduce ember entry during bushfire events. In bushfire-prone regions, it supports safe design compliance without sacrificing insulation value.

The product is also suitable for applications requiring a Bushfire Attack Level (BAL) of 0, ensuring compliance with Australian safety standards.

Applications & Suitability

This product is ideal for:

• Commercial metal roofs

• Residential applications

• Wall wraps when combined with bulk insulation, as Sisalation® enhances the performance of walls by improving weatherproofing and thermal resistance

• Roof sarking in hot and cold climate zones

• Builds requiring a water barrier and condensation control

• Projects seeking to meet total R value targets cost-effectively

Whether you’re a builder, roofer, or specifier, Sisalation® EHD (456) delivers outstanding durability and performance with a focus on long-term energy efficiency and protection.
