Kingspan Thermapitch TP10 80mm Roof Insulation

The Kingspan Thermapitch TP10 80mm board is a high-performance PIR insulation product engineered for pitched roof applications, accommodating both slate and tile coverings. Suitable for retrofit installations and new construction alike, this insulation board offers straightforward installation with easy cutting and handling characteristics.

The 80mm Kingspan TP10 delivers outstanding thermal efficiency for pitched roof and attic applications, enabling effective loft conversions and renovation work. It minimises thermal bridging through the roof structure, contributing to reduced heating requirements and lower energy expenditure. The board resists compression sagging throughout its service life and complies with Robust Details requirements under Part E of the Building Regulations for England and Wales.

Installation Options

1. Ideal for new builds and re-roofing projects, functioning as unventilated insulation positioned between and beneath rafters.
2. For loft insulation conversion schemes, this product works as ventilated insulation installed between and under rafter structures.
3. Kingspan 80mm insulation also performs effectively as unventilated insulation above and between rafters in new construction or re-roofing applications.

Facing System

During manufacture, Kingspan 80mm PIR receives a low emissivity composite foil laminate on both surfaces, which acts as a reflective barrier to boost thermal performance in unventilated cavities adjacent to the board.

Core Material

The 80mm Kingspan Thermapitch TP10 core utilises Nilflam® technology, delivering premium fibre-free rigid thermoset polyisocyanurate (PIR) insulation. Manufacturing employs a zero Ozone Depletion Potential (ODP) blowing agent combined with low Global Warming Potential (GWP) formulations.

Compressive Strength

Testing to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior) confirms that 80mm Kingspan PIR insulation regularly achieves compressive strength exceeding 140 kPa at 10% compression.

Water Vapour Resistance

When assessed under BS EN 12086:2013 (Thermal insulating products for building applications. Determination of water vapor transmission properties), this product typically demonstrates water vapour resistance substantially above 100 MNs/g.

Durability

The service life of 80mm TP10 depends on correct installation, adequate structural support, and appropriate usage conditions. When properly installed, the product can deliver an indefinite operational lifespan.

Fire Performance

80mm Kingspan Insulation TP10 achieves an F Euroclass rating under System 4 AVCP. When incorporated into pitched roof assemblies beneath appropriate roof coverings, it satisfies national standards for external fire exposure performance.
