CP 143-12:1970

This standard CP 143-12:1970 Code of practice for sheet roof and wall coverings is classified in these ICS categories:

• 91.060.10 Walls. Partitions. Façades
• 91.060.20 Roofs

This Code deals with methods of covering a roof or wall with copper sheet or strip in accordance with established practice. There are alternative methods of laying which are not included in the techniques described, as they are generally variations of traditional roof practice.

Recommendations are given in regard to the whole of the coverings above the wooden rafters for pitched roofs, and above the joists or the upper surface of the constructional base for flat roofs and walls.

Flashings and gutters are dealt with in so far as they are integral parts of the covering.

The dimensional co-ordination recommendations of Technical Committee B/94, Modular Co-ordination in Building, are embodied where appropriate to the Code.
