Quality & performance accreditations

All of Lorient's products are backed by extensive test evidence - but in addition to this, we also submit our products for independent performance verification, wherever a suitable scheme exists.

Three independent accreditation schemes exist with particular relevance to smoke seals and fire seals. Their purpose is to set benchmark quality and performance requirements, which go beyond the simple passing of a single smoke or fire test.

British Board of Agrément

BBA approvals provide independent assurance for the designer, specifier and end-user as to the “fitness-for-purpose” of building products. To achieve this accreditation, Lorient acoustic, smoke and fire seals were subjected to a comprehensive appraisal, conducted over a two year period. Rigorous audits of the manufacturer’s procedures are regularly conducted and it is a condition of BBA approval that a complete re-appraisal of the relevant products is carried out at, maximum, 3-year intervals. Lorient seals have successfully completed this review process on each occasion since the original approval was awarded. Lorient remains the only manufacturer of combined acoustic, smoke and fire seals to hold BBA approval on its mainstream range of seals.
