EINTEILIGE DAMPFSPERRE FÜR DIE ISOLIERUNG EINES GEKÜHLTEN ROHRES

摘要

An insulation system exhibiting superior ability to maintain insulation in a dry and effective condition and to remove moisture that condenses near a cold pipe is disclosed. The insulation system features a wicking material that surrounds the pipe and passes through a slit in the insulation. A vapor retarder surrounds the outer perimeter of the insulation. At the seam, a flap, containing openings that permit evaporation of moisture, extends over the slit and attaches to the vapor retarder. The vapor retarder provides enhanced performance by preventing the seepage of moisture back into the bulk of the insulation.
