Key Features of the Product:

1. Exceptionally slim insulation solution for partial fill cavity walls, representing one of the thinnest available options.
2. Reduced wall thickness permits increased natural light penetration, improving interior brightness.
3. Preserves an open cavity, effectively resisting damp ingress.
4. Low emissivity foil facings substantially improve thermal resistance within the cavity.
5. Lightweight cavity wall insulation offering straightforward transportation, handling, and installation.

Benefits of Kooltherm

1. Construction Efficiency: 40mm K108 Kingspan insulation boards are exceptionally lightweight, streamlining transport, handling and installation processes.
2. Increasing Property Value: The compact 40mm K108 profile maximises usable space and enhances long-term property value.
3. Occupancy Wellbeing: Manufactured with a fibre-free core composition.
4. Sustainability: Aligns with our Planet Passionate sustainability commitment.

The facings

The 40mm Kingspan Kooltherm K108 facings comprise a low emissivity composite foil, firmly adhered to the insulation core during production. This reflective layer significantly boosts thermal resistance in unventilated cavities adjacent to the board.

The core

The 40mm Kingspan Kooltherm core comprises a high-performance fibre-free rigid thermoset phenolic material, manufactured using a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).
