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 work, this product serves as ventilated insulation installed between and under rafter systems.
3. 110mm Kingspan insulation also works effectively as unventilated insulation between and over rafters in new construction or re-roofing applications.

Foil Facing Details

During manufacturing, Kingspan 110mm PIR receives a low emissivity composite foil bonded to both surfaces, functioning as a reflective barrier that boosts thermal resistance in unventilated cavities adjacent to the board.

Core Composition

The 110mm 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 with minimal Global Warming Potential (GWP).

Compression Performance

Tested to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 110mm Kingspan PIR insulation typically achieves compressive strength exceeding 140 kPa at 10% compression.

Moisture 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 well above 100 MNs/g.

Long-Term Performance

Product durability depends on correct installation, adequate structural support, and appropriate usage conditions. When properly installed, it can deliver an extended service life.

Fire Safety

110mm Kingspan Insulation TP10 achieves an F Euroclass rating under System 4 AVCP. When installed in pitched roof assemblies beneath appropriate roof coverings, it satisfies national external fire exposure standards.
