Everything You Need to Know About Roof Insulation Blanket Foil for Metal Roofs

A roof insulation blanket foil is one of the most effective solutions for improving energy efficiency, condensation control, and noise reduction in Australian homes and buildings—especially when installed beneath a metal roof.

At Metal Roofing Online, our 55mm foil faced insulation blanket is engineered to meet efficiency provisions, and the specific demands of Colorbond® and ZINCALUME® roofing systems. The glasswool fibers in our insulation blanket are bonded together using a thermosetting resin, creating a durable and effective product that ensures structural integrity and optimised thermal properties.

Why Use a Foil Insulation Blanket Under Metal Roofing?

Metal roofs are durable and long-lasting, but without proper insulation, they can transfer radiant heat, increase internal temperatures, and generate significant noise. Installing a foil insulation blanket for Colorbond® roofs solves these challenges:

• Condensation control: Reduces moisture build-up, mould risk, and ceiling damage

• Prevents heat loss in winter and unwanted heat gain in summer

• Reflective foil surface deflects radiant heat, keeping buildings cooler

• Helps reduce unwanted noise like rain noise, aircraft noise, and heavy rain

• Substantially reduce reverberant noise in metal roof structures

Engineered for Acoustic & Thermal Performance

Our glasswool blanket is crafted from finely spun molten glass fibres, forming a biosoluble formulation that’s safe, effective, and NCC compliant. The molten glass is spun into fine wool-like fibers, ensuring durability with the thermosetting resin, while the foil facing layer acts as a radiant barrier and moisture barrier.

Key benefits:

• Reduces reverberant noise and rain noise, improving comfort in sheds, homes, and commercial spaces

• Minimises greenhouse gas emissions by improving HVAC performance

• Contributes to a quieter space in winter and heavy rain seasons

Built for Australian Conditions

Our roofing blanket is designed to suit various applications, making it ideal for:

• Under metal roof insulation

• Sarking insulation beneath Colorbond® or Klip-Lok®

• Anticon roofing replacements

• Projects requiring one longitudinal edge for easier installation

It also supports energy compliance across:

• Residential homes

• Industrial buildings

• Renovation or new-build roofing projects
