Here are some "Applications":

The 50mm insulation suits a broad spectrum of applications, from solid concrete ground-based floors through to beam and dense block floors, suspended timber ground floors, and timber floors on battens.

The Facings

During manufacture, Kingspan 50mm PIR receives a low emissivity composite foil facing on both sides. This reflective layer boosts thermal resistance in any unventilated cavity adjacent to the board.

The Core

The 50mm Kingspan Thermafloor TF70 core employs Nilflam® technology, a premium fibre-free rigid thermoset polyisocyanurate (PIR) insulating material. Production uses a zero Ozone Depletion Potential (ODP) blowing agent with minimal Global Warming Potential (GWP).

Compressive Strength

When assessed to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 50mm 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) demonstrates this product typically delivers water vapour resistance well above 100 MNs/g.

Durability

The longevity of 50mm TF70 Floor Insulation relies on correct installation, adequate structural support, and appropriate use conditions. With proper installation, the product can perform indefinitely.

Fire performance

50mm Kingspan Insulation* TF70 achieves an F Euroclass rating under System 4 AVCP. When installed in pitched roof applications beneath suitable roof covering, it meets national requirements for external fire exposure.
