EXTERIOR JAMB CONSIDERATIONS

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.
