Introduction:

This project reviewed current standards and practice for the design, manufacture and assembly of built-up walls. The aim of the project was to produce a best practice guide for industry.

Built-up (layered) walls have been used successfully for centuries but recent advances in materials and the scale of these constructions has thrown up many technical questions and a number of walls have failed to deliver the intended performance.

The study considered the many forms of built-up wall construction and all aspects of performance including:

  • Watertightness
  • Air permeability
  • Structural performance
  • Movement
  • Robustness
  • Fire
  • Thermal performance
  • Condensation
  • Acoustics
  • Durability

The study also considered the design and construction process including roles and responsibilities.
