40mm Kingspan Kooltherm K107 Pitched Roof Board

40mm Kingspan Kooltherm K107 is a premium rigid thermoset phenolic insulation board engineered for pitched roof applications. This board delivers outstanding thermal performance across tiled or slated pitched roofs, dwarf walls, attic floors, dormer windows, and flat ceilings. For attic conversions without full re-roofing, these boards retrofit seamlessly into existing structures.

The 40mm Kingspan boards are straightforward to work with during installation. The material cuts cleanly and adapts readily to different rafter spacings, allowing precise fitting to your project specifications.

Key features

1. Exceptionally low thermal conductivity at 0.019 W/mK, delivering superior insulation performance.
2. Unaffected by air infiltration, preserving thermal efficiency and preventing energy loss through convection.
3. Resists water vapour transmission, protecting against moisture ingress and maintaining long-term insulation integrity.
4. Straightforward installation process, suitable for both new builds and retrofit applications.
5. Versatile across multiple roof configurations, making it suitable for diverse construction and renovation scenarios.
6. Non-deleterious composition with no harmful effects on health or environmental conditions.
7. Manufactured using a blowing agent with zero ozone depletion potential (ODP) and minimal global warming potential (GWP), supporting environmental responsibility.

Product Highlights:

1. Among the thinnest pitched roof insulation options available, achieving target U-values without excessive material depth.
2. Maintains structural integrity over time without sagging or performance degradation.
3. Particularly effective for loft conversions and renovation work, creating functional and thermally comfortable spaces.
4. Superior thermal performance reduces reliance on supplementary insulated plasterboard.
5. Low emissivity foil facing minimises radiant heat transfer through the roof envelope, enhancing energy efficiency.
6. Lightweight construction facilitates transport, handling, and site installation.
7. Represents our premium performance insulation portfolio, delivering consistent thermal efficiency.

Benefits of Kooltherm

Surface treatment

40mm Kingspan K107 requires an internal finish layer and must be covered with appropriate building board.

Cutting

1. Use a fine-toothed saw for cutting, or score with a sharp knife, snap over a straight edge, then cut the facing on the reverse side.
2. Maintain precise cuts to ensure tight joints and continuous insulation coverage.
