Kooltherm K107 Pitched Roof Board

Kooltherm K107 is a premium performance pitched roof insulation board. Suitable for use in tiled or slated pitched roofs, dwarf walls, attic floors, dormer windows and flat ceilings. The insulation boards can be simply retrofitted when converting an attic where re-roofing is not needed. The boards are easy to cut and handle, ensuring an efficient installation process. They can easily be trimmed to size to suit rafter spacings.
