Due to space limitations in the roof structure, it is often difficult to increase the extent of the insulation. In so far as it is possible, the best results are achieved by removing the original seaweed mats and replacing them with more modern insulation materials in the form of either batts or injected granules.

Regardless of the insulation type, adequate ventilation must be ensured between the insulation and the underside of the roof.

Further information can be obtained from suppliers of insulation materials.
