Building Regulations

According to a letter dated 30th July 2013, and issued by the Department for Communities and Local Government, “in certain circumstances an existing conservatory or porch can no longer be considered exempt from the requirement of Building Regulations if the amount of glazing in either the walls or roof is significantly reduced by further work or alteration”.

The roof system used by Thermolite has been independently tested and certified by JHAI, an accredited national building control approvals agency. These tests involve detail analysis and verification of the roof system from independently sourced structural calculations figures, along with further assessment checks on thermal performance and condensation resistance.

As a result our roofs are fully compliant with Building Regulations and have JHAI system approval. Meaning we can provide you with a Building Regulation “Final Certificate” on completion.
