Fire-rated duct wrap or board enclosure: what changes the choice?
The choice between wrap and board turns on the duct duty, geometry, space available, supports, access requirements, the surrounding construction and which arrangements the evidence covers.
Scott CunninghamHow do access panels and service penetrations affect a fire-rated enclosure?
Access panels and penetrations are common ways an enclosure stops matching its evidence. Both have to be part of the supported arrangement rather than cut in afterwards.
Scott CunninghamWhat is a fire-rated bulkhead or enclosure?
A fire-rated bulkhead or enclosure is a documented fire-resisting construction built around services, structure or geometry. The construction, not the board, is what carries the performance.
Scott CunninghamWhat records should exist for structural, duct, damper, transit and enclosure work?
Records should let the next person identify the member or asset, understand what was installed, and see the evidence relied on. Exact fields depend on system and contract.
