Kingspan Insulation is raising roof performance with Kingspan QuadCore 426 Roofboard, a flat roof insulation board delivering excellent thermal and fire performance, enhanced environmental credentials, and backed by an extended warranty.

Kingspan QuadCore 426 is the first insulation board to feature Kingspan’s advanced Quadcore technology. The high-performance, fibre–free, rigid neo-thermoset insulant delivers a thermal conductivity of 0.021 W/mK. This can allow roof U-values to be met with slim, light constructions.

In addition, following rigorous fire testing by FM Approvals, the global insurer testing body, it has received FM approval for use in Class 1 and non-combustible roof deck assemblies. This makes it well suited for applications such as warehousing, where asset protection is a key concern.

Kingspan QuadCore 426 is compatible with most mechanically fixed single-ply waterproofing systems and green roof systems, facilitating fast and simple installations over new or existing decks. The insulation material is manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
