Product Overview
Kingspan Thermaroof TR26 Flat Roof Insulation Board measuring 2400mm x 1200mm with a 110mm thickness. This high-performance rigid thermoset insulation board is specifically designed for flat roofs waterproofed with mechanically fixed single-ply membranes.
Manufactured with a fibre-free insulation core and low emissivity composite foil facings, it achieves excellent thermal conductivity of 0.022 W/m·K, delivering high levels of thermal efficiency.
The board is LPCB approved to LPS 1181 Part 1 and FM approved for Class 1 steel deck roof assemblies, confirming its suitability for demanding roof systems.
Resistant to water vapour transmission and fully compatible with most mechanically fixed single-ply and green roof systems, it provides long-term thermal reliability and structural stability.
Its rigid board format allows straightforward installation and consistent performance across large roof areas, with a 110mm thickness ensuring optimal thermal resistance for warm roof applications.
Features & Benefits
- High thermal efficiency: Achieves a low thermal conductivity of 0.022 W/m·K for excellent insulation performance.
- Durable rigid construction: Rigid thermoset core retains dimensional stability and compressive strength under mechanical fixing.
- Moisture resistance: Closed-cell structure resists the passage of water vapour, protecting the roof system from condensation risk.
- System compatibility: Fully compatible with most mechanically fixed single-ply membranes and green roof systems.
- Lightweight handling: Easy to cut, position, and secure, supporting fast-track installation on site.
- Environmental performance: Manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
- Certified quality: LPCB approved to LPS 1181 Part 1 and FM approved for Class 1 steel deck roofs.
- Sustainable sourcing: Certified to BES 6001 ‘Excellent’ for responsible sourcing, with a BRE Green Guide rating of A+.
- Size and format: Supplied as 2400mm x 1200mm boards with a 110mm thickness. Improves thermal ratings in standard-height roof designs.
Applications
- Flat roof systems: Suitable for use beneath mechanically fixed single-ply waterproofing membranes.
- Warm roof construction: Ideal for roofs requiring continuous insulation over the deck and vapour control layer.
- Green roofs: Compatible with extensive and intensive green roof systems.
- New build and refurbishment: Designed for use in both new and existing flat roof applications.
- Industrial and commercial buildings: Suitable for steel and concrete deck installations requiring robust insulation.
Installation Guidance
- Substrate preparation: Ensure deck is clean, dry, and structurally sound before installation.
- Vapour control layer: Install a separate vapour control layer unless used directly on a sealed metal deck.
- Fixing method: Mechanically fix insulation boards through the vapour control layer or metal deck using approved fasteners.
- Board layout: Lay boards tightly-butted with staggered joints to avoid thermal bridging.
- Falls and drainage: Construct falls within the roof deck or through a Kingspan Thermataper system to ensure adequate drainage.
- Protection and access: Restrict access to light foot traffic only; provide walkway protection where regular maintenance is required.
Compliance & Performance
- Thermal conductivity: 0.022 W/m·K.
- Fire performance: LPCB approved to LPS 1181 Part 1; FM approved for Class 1 steel deck assemblies.
- Environmental rating: BRE Green Guide rating of A+; manufactured under ISO 14001:2015 environmental management.
- Responsible sourcing: BES 6001 ‘Excellent’ certification for sustainable production.
- Quality assurance: Manufactured under ISO 9001:2015 quality and ISO 50001:2011 energy management systems.
- Standards compliance: Meets BS 4841-4 and BS EN ISO 6946 calculation methodologies for thermal performance.
- Important note: Always conduct a U-value and condensation risk analysis before installation; ensure all vapour control and waterproofing layers are correctly specified and installed to maintain full system integrity.
