ECN Forum Forums Code Related Discussion NEC & other Code issues Fireblocks - drilling holes

Bill,
Same thing here in MA the building inspector is last, I imagine to see what damage the trades have done to the structure and insulation as the building inspector verifies energy code compliance here.

As to who seals the holes, we try to negotiate that out of contracts (along with anything else that is not directly electrical) but often we end up doing the sealing.

The way that I've seen it happen is:

Framing Inspection (no Trades in yet)
Rough-in Electrical (maybe Plumbing too)
Insulation Inspection (after Insulation is in)
Finals (any order)

Bill

around here all inspectors are required to be combination inspectors.we do framing,plumbing,electrical,and mechanical in the same day.i think most building departments prefer the multi-purpose inspectors and we will become the norm.

Fire-caulking is required for any spaces that are required to maintain a certain rating such as between floor. This means around any space around any type of penetration. Large spaces are allowed to use Rocksul ( I think thats the spelling) which is basically a fiberglass insulation. Properly rated caulk as listed by UL as suitable for the purpose doesn't breakdown when it gets hot and stays pliable so expansion and contraction of penetrations do not create additional gaps.

The proper caulk around here is about 15 bucks a tube.
