Codes of Practice
In the absence of a European or British Standard the industry relies of Codes of Practice, generally produced by sector specific Trade Associations. These Code of Practice are typically produced by working groups consisting of members of the trade association and represent industry best practice at the time of writing, and cross refer to relevant British and European standards where appropriate. Radmat are members of a number of roofing trade associations and are actively involved in supporting the ongoing development of Codes of Practice.
Fire Safety Guidance Document
Working with MHCLG and NHBC, three roofing trade associations: National Federation of Roofing Contractors (NFRC), Liquid Roofing & Waterproofing Association (LRWA) and Single Ply Roofing Association (SPRA), have produced a guidance document clarifying the Changes in Regulations and Approved Documents Relating to Fire Safety For Flat Roofs on ‘Relevant Buildings’ in England. The Guidance Document also highlights that all upstands on balconies (‘waterproofing’ over air rather than over heated space) are classified as part of a ‘Specified attachments’ and therefore all upstand insulation board must be non-combustible, not just the insulation against habitable space or a compartment wall line. As members of both the LRWA and NHBC Radmat Building Products Ltd fully endorses this publication and adopts the guidance within it on all relevant projects.

GRO
Radmat is an active member of GRO, the sector trade association representing the green roof industry. A partnership of Industry and Stakeholders coming together to develop guidance for specification, design, manufacturing, installation and maintenance of Green Roofs, GRO produced its first code of practice in 2011 and issued an update in 2014. The GRO Green Roof Code of Best Practice for the UK is, as are all the other European Green roof standards and codes, based upon the FLL (the German Green Roof Guidelines).

Originally founded in 1979, LRWA aims to raise awareness of the technical and financial benefits of specifying liquid-applied roofing & waterproofing systems and to establish product and installation standards to ensure that optimum performance is achieved.
