Trade Grade Heat Insulation 2mm Roll, 1.5m x 40m, 60sqm

2mm Heat Insulation Roll

The Trade Grade Heat Insulation provides a high-performance thermal barrier designed to reduce radiant heat transfer in residential and commercial structures. This 2mm thick reflective material functions as both a radiant barrier and a vapor retarder, making it suitable for standard roofing and wall applications. The roll covers 60 square meters, allowing for efficient installation across large surface areas with minimal seams.

Built for the Job

This insulation is engineered for the demanding conditions of Kenyan job sites where high solar gain impacts internal temperatures. Contractors typically install this material directly under metal roofing sheets, clay tiles, or within wall cavities to block up to 97% of radiant heat. The lightweight polyethylene foam core provides a thermal break that prevents conductive heat transfer while the outer reflective layers handle radiation. It remains effective in high-humidity environments because the closed-cell structure does not absorb water or support mold growth.

• Primary roof underlayment for residential houses to reduce attic temperatures.

• Thermal wrapping for HVAC ducting to maintain air temperature and prevent condensation.

• Wall insulation in prefabricated buildings or steel-framed warehouses.

Product Highlights

Radiant Heat Resistance

The double-sided reflective surface reflects the majority of infrared radiation, significantly lowering the cooling load on the building interior.

Material Composition

• High-density 2mm closed-cell polyethylene foam core for consistent thickness.
• Reinforced reflective foil or metalized film for high tear strength on site.

Technical Specifications

What’s Included

• 1 x 60sqm Roll of 2mm Heat Insulation (1.5m x 40m)

On-Site & Workshop Notes

• Ensure a minimum 20mm air gap between the reflective surface and the roof sheet to maximize the radiant barrier effect.

• Overlap the edges by at least 50mm and seal with reinforced foil tape to maintain a continuous vapor barrier.

• Use galvanized staples or self-tapping screws with washers when securing the material to timber or steel purlins to prevent tearing.

• Store rolls upright in a dry area away from direct sunlight before installation to prevent edge damage.
