Kingspan Thermapitch TP10 120mm Roof Board

The 120mm 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, these insulation boards offer straightforward installation with easy cutting and handling.

The 120mm Kingspan TP10 delivers excellent thermal performance for pitched roof and attic spaces, enabling loft conversions and renovation work. It significantly reduces roof heat loss, helping to lower energy consumption, resists sagging throughout its service life, and satisfies Robust Details requirements under Part E of the Building Regulations for England and Wales.

Here are some possible rewrites for the section "Applications":

1. Recommended for new builds or re-roofing, can be used as unventilated insulation between and under rafters.
2. For loft insulation conversion projects, is recommended as ventilated insulation between and under rafters.
3. 120mm Kingspan Insulation is also suitable as unventilated insulation between and over rafters for new builds or re-roofing.

The Facings

During manufacturing, Kingspan 120mm PIR receives a low emissivity composite foil bonded to both surfaces. This reflective layer enhances thermal resistance in unventilated cavities adjacent to the board.

The Core

The 120mm Kingspan Thermapitch TP10 core utilises Nilflam® technology, a premium fibre-free rigid thermoset polyisocyanurate (PIR) material. Production employs a zero Ozone Depletion Potential (ODP) blowing agent with minimal Global Warming Potential (GWP).

Compressive Strength

When tested under BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 120mm Kingspan PIR insulation* typically achieves compressive strength exceeding 140 kPa at 10% compression.

Water vapour resistance

Testing to BS EN 12086:2013 (Thermal insulating products for building applications. Determination of water vapor transmission properties) confirms the product typically demonstrates resistance well above 100 MNs/g.

Durability

Service life depends on correct installation, adequate structural support, and appropriate usage conditions. When properly installed, this product can deliver an extended lifespan.

Fire performance

120mm Kingspan Insulation TP10 achieves an F Euroclass rating under System 4 AVCP. In pitched roof applications with appropriate roof covering, it meets national external fire exposure standards.
