Description / Abstract:

This document contains accepted practices for the fabrication and installation of sheet metal lagging. This document serves to establish standard methods to fabricate and install sheet metal lagging systems. This document does notprovide designs nor does it address safety issues.

While it is not practical to include every conceivable lagging detail, most common situations are addressed. As in the case of all design, construction and installation procedures, proper engineering judgment must be exercised in conjunction with the specific engineering and detail information being furnished by the designer.


The purpose of this document is to establish accepted industry practices for sheet metal lagging construction and installation. Lagging, as previously defined, is the material, typically steel or aluminum, ribbed or flat, used to cover insulation especially on large flat surfaces such as boiler walls, flues, ducts, precipitators, bag houses, selective catalytic reduction systems, air heaters, economizers, scrubbers, wind boxes, fans, etc.
