Installation 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 fitted between and under rafters.
3. 90mm Kingspan insulation also suits unventilated applications between and over rafters in new construction or re-roofing scenarios.

Foil Facing

The Kingspan 90mm PIR features a low emissivity composite foil bonded to both surfaces during manufacture, functioning as a reflective layer to boost thermal performance in unventilated cavities adjacent to the board.

Insulation Core

90mm Kingspan Thermapitch TP10 utilises Nilflam® technology, delivering a premium fibre-free rigid thermoset polyisocyanurate (PIR) core. The manufacturing employs 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), 90mm Kingspan PIR typically achieves compressive strength exceeding 140 kPa at 10% compression.

Moisture Resistance

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

Fire Safety

90mm 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 requirements for external fire exposure.
