Kingspan Thermapitch TP10 70mm Roof Board

The Kingspan Thermapitch TP10 70mm board is a high-performance PIR insulation board engineered for pitched roofs with slate or tile finishes. Suitable for both new construction and retrofit applications, this insulation board offers straightforward installation with easy cutting and handling.

This Kingspan TP10 board delivers outstanding thermal efficiency for pitched roof and attic spaces, enabling effective loft conversions and renovation work. It significantly reduces roof heat loss, contributing to lower energy consumption. The rigid structure resists sagging and meets Robust Details requirements under Part E of the Building Regulations for England and Wales.

Application 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 rafters.
3. The 70mm Kingspan board also performs well as unventilated insulation between and over rafters in new construction or re-roofing applications.

Foil Facing

During manufacturing, Kingspan 70mm PIR receives a low emissivity composite foil bonded to both surfaces. This reflective layer boosts thermal resistance in unventilated cavities adjacent to the board.

Insulation Core

The 70mm Kingspan Thermapitch TP10 core employs Nilflam® technology, a premium fiber-free rigid thermoset polyisocyanurate (PIR) material. Manufacturing utilises a zero Ozone Depletion Potential (ODP) blowing agent with minimal Global Warming Potential (GWP).

Compression Performance

Tested to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 70mm Kingspan PIR typically achieves compressive strength exceeding 140 kPa at 10% compression.

Moisture Resistance

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

Long-Term Performance

Longevity depends on correct installation, adequate structural support, and appropriate usage conditions. When properly installed, the board can deliver an extended service life.

Fire Rating

70mm Kingspan Insulation TP10 carries an F Euroclass rating under System 4 AVCP. When installed in pitched roof systems beneath suitable roof coverings, it meets national standards for external fire exposure.
