80mm EcoTherm Eco-Torch Flat Roof Insulation Board

80mm EcoTherm Eco-Torch Flat Roof Insulation Board delivers a thin-profile, high-performance thermal solution tailored for flat roof systems. Engineered for torch-on roofing applications, these robust boards work effectively with torch-applied felt, roll and pour felt systems, mastic asphalt and fully adhered single-ply membranes.

These 80mm boards suit a variety of standard roof decks including concrete, timber and metal, making them well-suited for both new build construction and flat roof refurbishment across residential and commercial properties.

Featuring thermal conductivity as low as 0.024 W/mK, Eco-Torch PIR insulation achieves target U-values through thinner roof build-ups, delivering efficient thermal performance whilst keeping roof structure compact.

Key benefits

• High-performance PIR flat roof insulation boards
• Suitable for torch-on felt and roll & pour roofing systems
• Compatible with mastic asphalt and fully adhered single-ply membranes
• Can be installed on concrete, timber and metal roof decks
• 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: Upgrades the thermal performance of existing flat roofs, provided the existing structure is sound and dry. PIR boards enhance energy efficiency in both commercial and residential refurbishments.
3. Green Roof Systems: Functions 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)
