WHAT IS THE DRIVING FORCE BEHIND MOISTURE FLOW THROUGH BUILDING ENVELOPE
DIFFERENCE IN VAPOR PRESSURE
THE LESS PERMEABLE A MATERIAL IS, THE _________ THE RESISTANCE TO WATER VAPOR FLOW
GREATER
MATERIALS WITH LOW ___________ ARE TERMED VAPOR RETARDERS
PERMEANCE
MATERIALS WITH LOW PERMEANCE ARE INCORPORATED IN ENVELOPE CONSTRUCTIONS AS A MEANS OF…
REDUCING THE FLOW OF WATER VAPOR AND THE ASSOCIATED RISK OF CONDENSATION OF THE VAPOR WITHIN THE ENVELOPE
PERMEANCE DEALS DIRECTLY WITH
