Kingspan Thermapitch TP10 100mm Roof Insulation

The 100mm Thermapitch TP10 is a high-performance PIR insulation board engineered for pitched roofs with slate or tile coverings. Suitable for both new construction and retrofit applications, this product delivers excellent thermal performance with minimal installation complexity. The 100mm boards cut and fit easily, streamlining the installation process.

This Kingspan TP10 board offers outstanding thermal efficiency for pitched roof and attic spaces, making it ideal for loft conversions and renovation work. It significantly reduces roof heat loss, contributing to lower energy consumption. The material resists sagging and complies with Robust Details requirements under Part E of the Building Regulations for England and Wales.

Application Options

1. Ideal for new builds or re-roofing projects, functioning as unventilated insulation positioned between and beneath rafters.
2. For loft insulation conversion schemes, recommended as ventilated insulation installed between and under rafters.
3. Suitable for new construction or re-roofing as unventilated insulation placed between and above rafters.

Foil Facing

During manufacture, Kingspan 100mm PIR receives a low emissivity composite foil bonding on both surfaces. This reflective layer boosts thermal resistance within any unventilated cavity adjacent to the board.

Insulation Core

The 100mm Kingspan Thermapitch TP10 core employs Nilflam® technology, delivering a premium fibre-free rigid thermoset polyisocyanurate (PIR) material. Manufacturing utilises a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).

Compression Performance

Tested to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 100mm Kingspan PIR insulation 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), the product typically 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 material can deliver an extended service life.

Fire Safety

100mm Kingspan Insulation TP10 carries an F Euroclass rating under System 4 AVCP. In pitched roof assemblies with suitable roof coverings, it satisfies national external fire exposure requirements.
