Here are some "Applications":

The 90mm insulation suits a broad spectrum of applications, from solid concrete ground-based floors and beam and dense block floors to suspended timber ground floors and timber floors on battens.

The Facings

Throughout manufacture, Kingspan 90mm PIR receives a low emissivity composite foil facing on both surfaces, functioning as a reflective layer to boost the thermal resistance of any unventilated cavity adjacent to the board.

The Core

90mm Kingspan Thermafloor TF70 core is manufactured using Nilflam® technology, a premium fibre-free rigid thermoset polyisocyanurate (PIR) material. The production process employs a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).

Compressive Strength

When assessed according to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 90mm Kingspan PIR insulation typically achieves compressive strength exceeding 150 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) shows this product typically delivers resistance well above 100 MNs/g.

Durability

The longevity of 90mm TF70 Floor Insulation relies on correct installation, adequate structural support, and appropriate usage conditions. When properly fitted, this product can deliver extended service life.

Fire performance

90mm Kingspan Insulation TF70 achieves an F Euroclass rating under System 4 AVCP. When deployed in pitched roof applications and positioned beneath appropriate roof coverings, it can satisfy national standards for external fire exposure.
