Air Bloc 07 Vapor Permeable Air Barrier Membrane
Vapor Permeable Air Barrier Membrane
Used to provide an air and rain barrier on exterior construction surfaces such as masonry, concrete, exterior grade gypsum, or rigid insulation in systems utilizing an interior vapor barrier such as polyethylene film where the entrapment of water vapor is to be avoided.
Description
Air Bloc 07 is a one-component solvent based, polymer modified bitumen, liquid membrane designed to resist air leakage when applied to construction surfaces while remaining permeable to the passage of water vapor.
Features
- Cold applied by trowel.
- Excellent adhesion to most construction surfaces such as masonry, concrete, stone, wood, gypsum board, rigid insulation and metal.
- Seals around projections such as brick ties.
- Cures to a flexible film.
- Minimal shrinkage on curing provides crack filling as well as bridging capabilities.
- High water Vapor permeance provides "breather" characteristic.
- Provides weather and water resistant coating.
Limitations
Avoid use in areas where solvent vapor may taint food or other susceptible products. Solvents in product may attack polystyrene insulation. The membrane should be allowed to cure for a minimum of 48 hours before polystyrene insulation is placed in direct contact. Not designed for permanent exposure to weather - protect as soon as possible, however can be exposed up to 6 weeks if necessary to accommodate construction scheduling.
Packaging
Air-Bloc 07 is packaged in 5 gallon or 55 gallon drums.
