The Aerolite Isotherm 100mm 1.2m x 6m is a ceiling and roof insulation product designed to help improve the thermal efficiency and comfort of residential and commercial buildings. Measuring 100mm thick x 1.2m wide x 6m long, the insulation provides 7.2m² of coverage per roll, making it suitable for new construction, renovations, and insulation upgrades.
Installed within suitable roof and ceiling spaces, the insulation helps reduce unwanted heat transfer between the interior of the building and the roof space. This can help keep indoor environments more comfortable throughout changing weather conditions.
100mm Ceiling and Roof Insulation
The Aerolite Isotherm 100mm insulation provides a substantial thermal barrier within suitable roof and ceiling applications. During warmer conditions, ceiling insulation can help reduce the amount of external heat entering the occupied space. During colder conditions, it helps limit heat loss through the ceiling.
The 100mm thickness provides a substantial layer of insulation, while the 1.2m x 6m roll allows installers to cover larger ceiling areas efficiently.
Each full roll covers approximately:
1.2m x 6m = 7.2m²
Actual coverage may vary depending on cutting, overlaps, roof configuration, and installation requirements.
Why Choose 100mm Roof Insulation?
A significant amount of unwanted heat transfer in a building can occur through the roof and ceiling area. Installing suitable insulation helps create a thermal barrier between the occupied space and the roof.
Effective ceiling insulation can contribute to improved indoor comfort and may reduce reliance on heating and cooling equipment when correctly selected and installed.

Installation Guidelines
Measure the ceiling or roof area before purchasing to determine the required number of rolls. Allow for cutting and installation waste when calculating the total quantity required.
Install the insulation evenly across the required area without leaving unnecessary gaps. Avoid excessive compression, as compressing insulation can affect its intended thermal performance.
Take appropriate precautions around electrical wiring, recessed lighting, heat-producing equipment, chimneys, and other roof-space components. Installation should follow the specific manufacturer’s instructions and applicable South African building requirements.
Storage and Handling
Keep the insulation clean, dry, and protected before installation. Store it away from excessive moisture and sources of ignition.
Wear suitable protective clothing and follow the manufacturer’s handling and safety recommendations during cutting and installation.
