tIntroduction <br /> In addition to performing as an interior vapor retarder, MemBrain�" may be installed as a continuous, interior air <br /> , barrier system over unfaced fiber glass or other insulation rec�uiring a separate vapor/air barrier. MemBrain is <br /> recommended for interior vapor retarder and air barrier applications, located at the "warm in winter" (moderate to <br /> high heating climates) side of the building envelope. MemBrain sheeting is not intended for exterior applications <br /> ' where it would be e.xposed to the elements or IIV light. <br /> Safety note:When installing MemBrain,make sure that you are wearing the appropriate personal protective equipment. The following <br /> ' items are recommended: safety goggles or glasses and gloves. <br /> ' Required Materials <br /> The following materials should be used to create the <br /> MemBrain Continuous Air Barrier�Smart Vapor <br /> , Retarder System: <br /> • MemBrain Con[inuous Air Barrier&Smart Vapor <br /> t Retarder <br /> - Sheeting available in 8' 4", 9' 4", 10' 4° % <br /> and 12' 4"widths, 100'lengths (2.44, Z.74, 3.05 and �,;,1 <br /> M�� <br /> 3.66 mm widths, 30.48 m length) <br /> , . <br /> • Approved SealanUCaulk Wall Top <br /> Plate <br /> -Silicone-based sealants ' <br /> � -Must conform to ASTM C920 or C834 specifications � Cavity <br /> • Approved Sheathing Tape Insulation <br /> - Canadian Construction Materials Centre (CCMC) <br /> ' n,�M��� M�Me�,i„,°� Vapor <br /> evaluated or other code-approved sheathing tape. <br /> Permeable <br /> Exterior <br /> ' Air Barrier <br /> t (Coordinate <br /> MemBrain installation with <br /> Sheeting the framing <br /> (Air Barrier/ � � ,*"`� contractor) <br /> , Vapor Retarder) <br /> � - � <br /> t <br /> Rim Joist <br /> � "r" '�U'�--- Wal I <br /> � �v��ni,u nae,aew�,,;�' Bottom <br /> � � � �� Plate <br /> ���3 <br /> ' <br /> ' <br /> J�� ��- <br /> ' <br /> � Figure]: Muin�ain air banlrr conlintii�v a(r�im jois(s,co�ner�s,parti(ioii iva11 inter Jaces aiid ceili�igs. <br /> � 2 CertnfnTeed Corpora(ion,t3uilding5cicnce De��arCnunt <br />
