Kingspan Kooltherm K107 25mm Pitched Roof Board

25mm Kingspan Kooltherm K107 delivers high-performance thermal insulation engineered specifically for pitched roof applications. This rigid thermoset phenolic board suits tiled and slated roofs, dwarf walls, attic floors, dormer windows, and flat ceilings. For attic conversions without full re-roofing, these boards retrofit efficiently into existing structures.

The 25mm Kingspan boards feature straightforward installation characteristics. They cut and handle readily, allowing quick trimming to match various rafter spacings and site-specific dimensions.

Surface treatment

25mm Kingspan K107 requires an internal finish layer and must be backed by 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. Trim accurately to ensure tight joints and consistent insulation coverage.
