The 140mm Thermapitch TP10 is a high-performance PIR insulation board engineered for pitched roofs with slate or tile coverings. Ideal for both new construction and retrofit applications across multiple thicknesses, these insulation boards offer straightforward installation with minimal cutting and handling requirements.
The 140mm Kingspan TP10 delivers outstanding thermal efficiency for pitched roof and attic spaces, enabling loft conversions and renovation work whilst significantly reducing roof heat loss to lower heating expenses. The product resists sagging throughout its lifespan and satisfies Robust Details requirements under Part E of the Building Regulations for England and Wales.

During manufacture, Kingspan 140mm PIR receives a low emissivity composite foil bonded to both surfaces, functioning as a reflective layer that boosts thermal resistance in unventilated cavities adjacent to the board.
140mm Kingspan Thermapitch TP10 utilises Nilflam® technology to create a premium fibre-free rigid thermoset polyisocyanurate (PIR) core. Manufacturing employs a zero Ozone Depletion Potential (ODP) blowing agent with minimal Global Warming Potential (GWP).
To BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 140mm Kingspan PIR insulation typically achieves compressive strength exceeding 140 kPa at 10% compression.
Per BS EN 12086:2013 (Thermal insulating products for building applications. Determination of water vapor transmission properties), the product typically demonstrates resistance well above 100 MNs/g.
Product longevity depends on correct installation, adequate structural support, and appropriate usage conditions. When properly installed, the material can deliver an extended service life.
140mm Kingspan Insulation TP10 achieves F Euroclass rating under System 4 AVCP. When installed in pitched roof assemblies beneath suitable roof coverings, it meets national external fire exposure criteria.
