System Engineering and Selection - Johns Manville The preservation of the thermal efficiency of the roof insulation is also becoming more important and therefore designers should give careful consideration to the use and proper design of vapor retarders in the roofing system
Vapor Barriers or Vapor Retarders | Department of Energy A vapor retarder is a material that reduces the rate at which water vapor can move through a material The older term "vapor barrier" is still used even though "vapor retarder" is more accurate
