EcoTherm Eco-Torch 120mm Flat Roof Insulation Board

EcoTherm Eco-Torch 120mm Flat Roof Insulation Board delivers a compact, high-performance thermal solution engineered for flat roof systems. Purpose-built for torch-applied roofing installations, these robust boards work seamlessly with torch-applied felt, roll and pour felt systems, mastic asphalt and fully adhered single-ply membranes.

Installation is straightforward across various structural roof decks including concrete, timber and metal, making these boards suitable for both new construction and flat roof renovation work in residential and commercial properties.

Featuring thermal conductivity as low as 0.024 W/mK, Eco-Torch PIR insulation achieves target U-values with thinner roof assemblies, delivering effective thermal performance without compromising on roof structure depth.

• Low thermal conductivity (from 0.024 W/mK) for excellent insulation performance
• Helps achieve required U-values with slim roof constructions
• Suitable for new build and refurbishment flat roof projects

Application of PIR Flat Roof Insulation Boards

1. New Build Projects: Meets current Part L Building Regulations with a slim-profile insulation solution, helping achieve required U-values without increasing roof thickness.
2. Refurbishment Projects: Enhances thermal performance of existing flat roofs when the existing structure is sound and dry. These eco-friendly PIR boards boost energy efficiency in both commercial and residential renovation schemes.
3. Green Roof Systems: Works as the insulation layer beneath green roof build-ups, delivering reliable thermal performance whilst supporting vegetative roof layers.

Compatible Roof Decks: Eco-Torch and other PIR boards can be installed on all common structural roof decks:

1. Timber Decks: Plywood, OSB/3, or timber boarding
2. Concrete Decks: Precast or in-situ concrete slabs
3. Metal Decks: Profiled steel or metal decks (ensure all board joints are supported by the deck crowns)
