Cooler interiors in summer
Reflective foil blocks radiant heat from the roof and walls, reducing indoor temperatures and the need for air conditioning. This is most noticeable on hot days when the roof space can reach extreme temperatures.
What Sisalation Insulation Does in Melbourne
Sisalation is a reflective foil insulation used under metal or tile roofing and behind wall cladding. It reflects radiant heat away from the building envelope, reducing summer heat gain through the roof and walls. In Melbourne’s hot dry summers, this keeps living spaces cooler and eases the load on air conditioning. It also helps control condensation and dust in the roof space when paired with bulk insulation.
- Reflects up to 97% of radiant heat
- Installed with an air gap for effectiveness
- Suitable under roofing and behind wall cladding
- Helps manage moisture and dust in roof spaces
Why Melbourne Homes Need Sisalation
Melbourne’s hot northerly winds and heatwaves push radiant heat through roofs and walls, making interiors uncomfortable and driving up cooling costs. Sisalation addresses this by reflecting heat before it enters the building, which is especially effective in older brick veneer and weatherboard homes with limited existing insulation.
Reduced energy costs
By cutting heat gain, sisalation lowers the workload on cooling systems. Homeowners typically see a reduction in energy bills during the warmer months, particularly in homes with metal roofs or large west-facing walls.
Moisture and dust control
The foil layer acts as a barrier against dust and moisture entering the roof space. This keeps the area cleaner and reduces the risk of condensation forming on timber framing or ceiling linings.
Long-lasting performance
Sisalation does not compress or degrade over time like some bulk insulation. Once installed with the correct air gap, it maintains its reflective properties for the life of the building.
Works with bulk insulation
For best results, sisalation is paired with bulk insulation such as glasswool or polyester batts in the ceiling. The foil handles radiant heat, while the bulk material traps still air to slow conductive heat flow.
Minimal thickness, maximum effect
Unlike thick batts, sisalation is a thin laminate that adds little bulk. This makes it ideal for retrofits where space is limited, such as under low-pitched roofs or in narrow wall cavities.
How We Install Sisalation in Melbourne
Installing sisalation requires careful placement to maintain the air gap that makes it effective. We follow a methodical approach to ensure the foil is continuous and properly sealed at all edges and penetrations.
1
Roof or wall assessment
We check the roof structure or wall framing to confirm there is enough space for the foil and the required air gap. For roofs, this means measuring between the rafters and the underside of the roofing material. For walls, we verify cavity depth behind cladding.
2
Surface preparation
The area is cleared of debris, dust and any old insulation that may interfere with the foil. We also check for and note any cables, pipes or downlights that need to be worked around to maintain safe clearances.
3
Foil installation
Sisalation is rolled out and fixed in place with staples or adhesive, ensuring it is taut and free of tears. For roofs, it is installed directly under the roofing material. For walls, it is placed behind the cladding before it is refitted.
4
Sealing and finishing
All edges and joins are sealed with foil tape to prevent heat leakage. We ensure the air gap is maintained and that the foil is not compressed by other materials or fasteners. The space is left clean and ready for any additional bulk insulation if required.
Sisalation Insulation for Melbourne Homes
Melbourne’s mix of older weatherboard and brick veneer homes, along with newer builds, often lacks effective radiant heat barriers. Sisalation is a practical upgrade for these properties, particularly in suburbs exposed to hot northerly winds and intense summer sun. It is commonly installed during roof replacements or re-cladding projects, but can also be retrofitted in accessible roof spaces.

Effective Radiant Heat Barrier for Melbourne
Sisalation insulation is a reflective foil laminate designed to block radiant heat from entering a home through the roof or walls. In Melbourne, where summer temperatures can soar, this type of insulation is highly effective at keeping interiors cooler by reflecting up to 97% of radiant heat. It is installed with an air gap to ensure maximum performance, making it a smart choice for both new builds and retrofits.
For Melbourne homes, sisalation is particularly beneficial under metal roofing, which can absorb and transfer significant heat into the roof space. It also works well behind wall cladding in brick veneer or weatherboard homes, reducing heat gain through external walls. When combined with bulk insulation like glasswool or polyester batts, it provides a comprehensive thermal barrier that addresses both radiant and conductive heat flow.
The installation process involves assessing the roof or wall structure to ensure there is adequate space for the foil and the necessary air gap. The area is prepared by removing debris and old insulation, then the sisalation is carefully installed and sealed. This ensures it remains effective for the life of the building, providing long-term energy savings and improved comfort during Melbourne’s hot summers.
