About the Roof Insulation Blanket with Foil 55mm
This 55mm foil-backed roof insulation blanket is designed for use under a metal roof to improve thermal comfort and reduce noise, including rain noise and other external sounds. The insulation blanket contains tiny air pockets between the fibres, which help disrupt heat flow and aid in moisture control. Proper installation and material choice can lead to improved moisture control, insulation, and noise reduction for your metal roof. It combines a thick polyester blanket with a reflective foil layer that deflects radiant heat away from your roof space.
Suitable for both new builds and re-roofing projects, this insulation blanket is compatible with COLORBOND® and ZINCALUME® steel roofing. It’s safe to handle, easy to install, and perfect for homes, sheds, and commercial buildings. In addition to enhancing thermal comfort, the insulation helps keep your home cooler in summer.

Acoustic Benefits
One of the standout advantages of installing a roofing blanket with a medium-duty foil facing is its exceptional acoustic insulation properties. This insulation blanket is engineered to substantially reduce reverberant noise and unwanted noise transfer through your roof, making it an ideal solution for both residential and commercial buildings.
Whether you’re dealing with the persistent sound of heavy rain, the impact of hail, or even aircraft noise, the blanket layer works to absorb and dampen these disturbances. The result is a quieter, more peaceful indoor environment where acoustic comfort is prioritised. By choosing a roofing blanket with effective foil facing, you can enjoy a home or workspace shielded from external noise for a more comfortable, productive atmosphere year-round.
Condensation Management
Managing condensation is essential for protecting your roof and ceilings from moisture-related damage. Roofing insulation blankets with a reflective foil facing are specifically designed to provide effective condensation control, especially under metal roofs and cladding that are prone to moisture build-up. The anti-condensation function works by interrupting heat transfer, preventing warm, moist air from meeting the cold metal surface. This reduces the formation of condensation droplets, safeguarding plasterboard ceilings, fibre cement, and other materials from water damage and mould. Installing a reflective foil insulation blanket helps ensure a healthier and longer-lasting roof structure.
Safety Features
Safety is a top priority when it comes to roofing insulation. This blanket is manufactured with non-combustible fibres, making it a reliable choice for bushfire-prone areas and high-risk environments. The reflective foil facing not only enhances thermal performance but also acts as a barrier against radiant heat, helping to reduce heat transfer and the risk of fire spread.
The insulation is made from non-toxic, non-conductive materials, ensuring it’s safe for both residential and commercial use. With these robust safety features, homeowners and builders can have confidence that their property is protected and compliant with Australian safety standards.
Environmental Benefits
Choosing a roofing blanket insulation is a smart move for both your home and the environment. Engineered for energy efficiency, this insulation blanket helps reduce greenhouse gas emissions by lowering the need for heating in winter and cooling in summer. Many insulation blankets are produced using recycled materials and bio-based binders, supporting sustainable building practices. Free from harmful chemicals such as formaldehyde, these products contribute to a healthier indoor environment and a smaller carbon footprint.
Installation Guide
- Always install with the foil side facing down into the roof space.
- Slightly overlap rolls to avoid heat gaps.
- Run insulation into the gutter by at least 20mm to prevent water ingress.
- Maintain a 25mm air gap under the roof sheet for maximum performance.
- Tape seams for a continuous vapour barrier.
