Guidance & Standards

The 2020 SPRA Single Ply Design Guide (S1/2020) is now available

The full SPRA Design Guide and all SPRA Guides and Quality Standards, together with many vital industry references are available in our ‘Guidance and Standards’ section of the SPRA website. Over twenty-five years, the Guide has reflected the transition from prescription and standard ‘solutions’ to a more performance-based construction process based on harmonised European Standards. Judging from the feedback SPRA gets, it’s very highly respected amongst our customers out there.
