DryRight
fiberglass insulation helps building professionals control moisture within wall
cavities. The insulation is faced with the company’s MemBrain, a patented vapor
retarder that changes its molecular permeability under varying humidity
conditions to allow wall cavities to stay dry and help reduce the risk of
damaging mold and mildew. The permeance of DryRight is 1 perm or less at normal
conditions and increases to greater than 30 perms when the humidity changes to
near 90 percent. This process allows closed building envelope systems to
increase their drying potential with seasonal climatic
changes.
