Bibliography
Specifies recommendations on the design and application of flat roofs with continuously supported roof coverings. Covers weather-tightness, drainage, thermal design, sound installation, condensation control, structural support, fire precautions, maintenance and repair.
This code of practice gives recommendations on the design and application of flat roofs with continuously supported roof coverings. It covers weathertightness, drainage, thermal design, sound insulation, condensation control, structural support, fire precautions, maintenance and repair. The recommendations are applicable to terraces, podia, parking decks and green/garden roofs; however these particular types of roof also require consideration of additional factors, beyond the scope of this code of practice.
This code of practice is applicable to roof coverings at a pitch not greater than 10° to the horizontal.
NOTE Provided that the design conditions are similar, the recommendations given in this code may also be applied to roofs with slopes greater than 10°, but for steep roofs many of the recommendations may not apply.
This code of practice does not apply to roofs with self-supporting coverings, cold stores and high temperature enclosures, or to slated or tiled roofs.
