Here are some "Applications":

This 100mm insulation suits numerous applications, from solid concrete ground-based floors and beam-and-block construction to suspended timber ground floors and timber joisted arrangements.

The Facings

During production, Kingspan 100mm PIR receives a low emissivity composite foil facing on both surfaces, which acts as a reflective barrier to boost thermal resistance in any unventilated cavity space adjacent to the board.

The Core

The 100mm Kingspan Thermafloor TF70 core employs Nilflam® technology, a premium fibre-free rigid thermoset polyisocyanurate (PIR) material. Manufacturing uses a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).

Compressive Strength

When assessed to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 100mm Kingspan PIR insulation typically achieves compressive strength exceeding 150 kPa at 10% compression.

Water vapour resistance

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

Durability

The lifespan of 100mm TF70 Floor Insulation depends on correct installation, adequate structural support, and appropriate usage conditions. When properly installed, it can perform reliably for many decades.

Fire performance

100mm Kingspan Insulation TF70 achieves an F Euroclass rating under System 4 AVCP. When deployed in sloped roof applications beneath appropriate roof coverings, it satisfies national standards for external fire exposure.
