Kingspan Thermapitch TP10 30mm Roof Insulation

The Kingspan Thermapitch TP10 in 30mm thickness 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 insulation board offers straightforward installation with minimal cutting and handling requirements.

Key benefits of the 30mm Kingspan TP10 include exceptional thermal efficiency for pitched roof and attic spaces, enabling loft conversions and renovation work, substantial reductions in roof heat loss to lower heating bills, excellent dimensional stability without sagging, and compliance with Robust Details for Part E Building Regulations across 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. Also performs effectively as unventilated insulation between and over rafters in new construction or re-roofing scenarios.

Foil Facing System

The Kingspan 30mm PIR boards feature low emissivity composite foil bonded to both surfaces during manufacture, creating a reflective barrier that boosts thermal resistance in unventilated cavities adjacent to the board.

Insulation Core

The Kingspan Thermapitch TP10 30mm core utilises Nilflam® technology, delivering a premium fibre-free rigid thermoset polyisocyanurate (PIR) material. Manufacturing employs zero Ozone Depletion Potential (ODP) blowing agents with minimal Global Warming Potential (GWP).

Compression Performance

Tested to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 30mm Kingspan PIR insulation typically achieves compressive strength exceeding 140 kPa at 10% compression.

Moisture Resistance

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

Long-Term Performance

The lifespan of 30mm TP10 depends on correct installation, adequate structural support, and appropriate usage conditions. When properly installed, the product can deliver potentially indefinite durability.

Fire Safety

30mm 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 external fire exposure requirements.
