What standards does your roofing meet?

Topseal GRP roofing, as installed by Cotswold Fibreglass Roofing Ltd, meets the following recognised standards. This gives you further reassurance that the materials and workmanship will give the long-lasting, high performance results that you expect.

Standards Compliance

  • BBA (British Board of Agrément) certification
  • Fire retardant to Class 1 (if required)
  • Part L Building Regulations compliance (as of April 2006):
  • Topseal can be specified with a calculated ‘U’ value of 0.25W/m2K or 0.20W/m2K (Calculated in accordance with BS EN ISO 6946)

What is BBA certification?

The British Board of Agrément (BBA) is an organisation partnered with the government, whose governing board includes representation on behalf of the Office of the Deputy Prime Minister. The BBA provides authoritative and independent information on the performance of building products.

Assessment for BBA certification involves three distinct areas: 

  • Laboratory testing
  • Site inspections undertaken by the BBA’s own Inspection Services team
  • Factory production control

Topseal’s British Board of Agrément Certificate (viewable at [www.bbacerts.co.uk no.93/2932]) guarantees that each Topseal installation can only be completed by trained and approved contractors and that every Topseal branded material must undergo constant quality control checks and be traceable right back to manufacture.

Why is BBA certification important?

Many Local Authorities or larger contracts will require the security of BBA certification in the roofing system used by their contractors. This is an established standard of quality throughout the whole of the building industry. 

Because of this, it is important that all approved Topseal contractors maintain a high standard of service and always operate according to the guidance of the Topseal Installation Manual as this forms part of the basis for BBA certification. Deviating from this guidance not only jeopardises the BBA certification of the Topseal system, but also the individual contractor’s approval as a Topseal contractor.

Any questions about specific technical aspects of the Topseal GRP roofing system can usually be answered by referring to the BBA certificate.
