Isotherm 55mm 1.2m x 10m Insulation

The Isotherm 55mm 1.2m x 10m Insulation is a polyester thermal insulation roll designed to help improve indoor comfort by reducing heat transfer through roof and ceiling areas. With a 55mm thickness, 1.2m width and 10m length, each roll provides approximately 12m² of nominal coverage before allowing for cutting and installation requirements.

Isotherm insulation is commonly installed in ceiling and roof spaces to help keep buildings cooler during hot weather and warmer during colder conditions, making it a practical insulation solution for South African homes and compatible building projects.

Why Choose Isotherm Insulation?

Installing ceiling insulation helps reduce the amount of heat transferred between the interior of a building and the roof space. During summer, this can help limit heat entering living areas, while during winter it can help reduce heat loss through the ceiling.

The polyester construction also makes Isotherm a practical choice for residential renovations, new builds and insulation upgrades.

Improve Year-Round Indoor Comfort

The Isotherm 55mm 1.2m x 10m Insulation provides a practical way to improve the thermal performance of a building. Roof and ceiling areas can account for significant heat transfer, particularly where little or no insulation has previously been installed.

By creating an insulating layer above the ceiling, Isotherm helps slow the movement of heat. During hot South African summers, this can help reduce the amount of roof-space heat transferred into rooms below. During colder periods, insulation helps retain internally generated heat for longer.

Improved thermal performance can also reduce reliance on heating and cooling equipment. The actual energy savings will depend on factors such as the building design, climate, insulation thickness, installation quality and other components of the building envelope.

Each roll measures 1.2m x 10m, providing a nominal material area of approximately 12m². Actual project coverage may vary because of cutting, obstacles, overlaps and the configuration of the ceiling or roof structure.

Correct installation is important. Insulation should be fitted consistently across the intended area while minimising unnecessary gaps. Particular care should be taken around electrical fittings, downlights, wiring and other heat-producing components, with all relevant installation and electrical safety requirements followed.

The required insulation thickness and thermal performance can vary according to the building type and applicable energy-efficiency requirements. For new construction or regulated building work, the appropriate insulation specification should therefore be confirmed before installation.

Installation Considerations

Measure the ceiling or roof area before calculating quantities.
Allow additional material for cutting and installation requirements.
Install the insulation evenly without unnecessary gaps.
Do not unnecessarily compress the insulation, as this can affect thermal performance.
Follow applicable requirements around downlights and electrical equipment.
Ensure electrical wiring and fittings are safe before working in the roof space.
Wear suitable protective clothing and equipment when working in ceiling areas.
Follow the manufacturer’s installation instructions and applicable building requirements.
