Vapor retarders do just as they are named they reduce vapor diffusion but not all vapor retarders are equal.

Vapor retarders for membrane roofing systems.

Vapor retarder sa 31 can also serve as temporary roof protection in areas limited to light construction traffic. There is often confusion between air barriers and vapors retarders. A vapor retarder is a material or system that is designed as part of the roof system to substantially reduce the movement of water vapor into the roof system where it can condense. The need for use and design of a vapor retarder in the design of a roof system used to be a hotly debated topic.

The purpose of a vapor retarder is to minimize or reduce water vapor diffusion into a low slope roof or wall system. Vapor retarder primer sb is a solvent based primer vapor retarder primer sb us is a solvent based primer used to prime wood concrete lightweight concrete approved gypsum boards and gypsum decks prior to the application of sika s self adhered vapor retarders or sarnafil g 476 sa self adhered waterproofing membrane. The fiberglass reinforcement provides high strength to the membrane which guarantees an excellent mechanical performance. It can be left exposed for up to two 2 months.

That reduction of air and moisture infiltration can then help improve roof longevity. It appears now when vapor retarders are needed more than ever the design community seems to have lost interest which is not good considering how codes and standards altered through concerns for energy savings have changed how buildings are designed constructed and operated. A roof design that includes an adhered roof membrane with multiple layers of insulation with board joints offset and staggered over a vapor retarder air barrier helps lower the risk that air and the moisture it carries will infiltrate the roof system. When discussing air barriers roofing membranes and the building envelope another important topic comes to mind.

The lower the perm rating the less diffusion occurs through a material. Typically a vapor retarder has to have a perm rating of 1 0 or less to be successful. It consists of reinforced aluminum foil with self adhesive bituminous backing protected by a release film. Colvent 180 tg is a partially adhered heat welded elastomeric modified bitumen base ply for use in approved multi ply membrane and flashing assemblies or as a vapor retarder.

Colvent 180 tg is composed of non woven polyester reinforcement. Everyone knows that water in roof systems is never a positive. The firestone v gard vapor control membrane is designed to be used as vapor control layer in firestone roofing systems. Gaf sa vapor retarder is an sbs modified bitumen vapor retarder for use in approved gaf roof assemblies.

Gaf sa vapor retarder is composed of a proprietary formulation of elastomeric styrene butadiene styrene sbs polymer modified bitumen in combination with a high tack self adhesive.
