EXTERIOR JAMB CONSIDERATIONS
Thermal Breaks
Air/Vapor Barrier
Thermal Breaks
- To minimize thermal breaks materials may not be able to be returned in the normal way, i.e. brick veneer can not return to the CMU
- The frame needs to be wide enough to span the gap. A 6 3/4" min. frame is usually sufficient
Air/Vapor Barrier
- The Air/Vapor Barrier needs to be sealed to the building.
