Index

Recommends principles to be followed in selecting the most suitable insulating systems for particular requirements of pipework, plant and equipment. Gives guidance on design, work onsite and application, and on the use and choice of finishes. Primarily intended for fixed installations but also applicable to land transport and marine use.
