Poly 6 Mil CGSB Vapour Barrier Clear Size:6 mil 1000 SF 18" x 4" SE BSVapor barriers protect homes by preventing water vapor from escaping the building envelope. Leaking vapor barriers can lead to condensation in the walls and cause the wood to rot. In Canada, the Canadian General Standards Board (CGSB) developed a standard for greatly improved vapor barriers required for the building code of new home construction. This film made to meet the requirements of CAN CGSB 51. 34 M86 has clearly defined and tested properties
