BS 8612: Dry-fixed Ridge, Hip and Verge Systems for Slating and Tiling

Product Specifications

Marley is widely recognised as one of the early pioneers of the dry fix industry, developing some of the first high-performance purpose-made systems.

Whilst many purpose-made systems are still popular today as part of single-source system specifications, there has been an industry-wide move towards complete kit solutions, popular with merchant distributors because of their compatibility with a range of tile and slate types. Marley offers both of these options with our purpose-made and Universal kit ranges.

What is the British Standard BS 8612?

The new standard, which has been called BS 8612: Dry-fixed Ridge, Hip and Verge Systems for Slating and Tiling – Specification, specifies the performance requirements and methods of test for dry-fixed ridge and hip systems connected to timber ridge/hip battens, ridge boards or hip rafters, and for dry-fixed verge systems, which are installed with ridge, hip and verge components used with slates and tiles.

Why has the new standard been released?

Exponential growth in the dry fix market - fuelled by recent changes to industry standards and guidelines - has resulted in a huge array of options for specifiers and installers for dry fix products. Consequently, there are now sufficient numbers of competing systems (of varying performance and quality), as to warrant the introduction of a new British Standard, which ensures minimum performance requirements and introduces a recognised standard for the dry fix industry..

What are the requirements of BS 8612?

BS 8612 sets out the key quality and performance criteria and test methods under six essential requirements:

  1. Material specification and durability
  2. Mechanical resistance
  3. Ventilation for ridge and hip systems
  4. Rain performance
  5. Geometric characteristics
  6. Marking, labelling and installation instructions
