EXTERIOR WALL SYSTEMS SINCE 1947

Air & Moisture Barrier

air-moisture-barrierAir and Moisture Barriers are required in building walls, regardless of region or climate. Controlling air leakage through the building envelope is critical to achieving high building energy efficiency. Research has shown that air barriers can play a larger role in energy efficiency than increasing insulation thickness. But unlike building wrap barriers that are penetrated by staples and fasteners for their attachment, we employ a system that provides seamless control over air and moisture to improve building performance and occupant comfort.

 


 

Key Features

 Waterproof Air Barrier

Protects the wall from moisture intrusion minimizing risk of water damage and associated repair costs.

 Air Barrier

Minimizes airflow through the wall construction reducing risk of condensation caused by air leaks.

 Energy Efficient

Lowers energy costs by reducing air leakage and heating/cooling loads.

 Fire Tested

Compliant with ASTM E-84, NFPA 285 and ASTM E-119 for use on non-combustible construction.

 Durable

Fully adhered and attached to substrate. Does not tear with exposure to weather during construction or while in service.

 Indoor Air Quality

Helps to protect against growth of mold and mildew.

 

 


 

Air and Moisture Barrier

We use a ready-mixed flexible waterproof air barrier membrane for use in Therm ci Systems. It is applied directly to vertical above grade wall sheathing and concrete masonry, and functions as a waterproof air barrier when combined with the joint and rough opening treatment.

 

  • PERMEABILITY: Vapour Permeable
  • SUBSTRATE TYPE: Glass-Mat Gypsum Sheathing, Exterior Plywood, OSB, Concrete Masonry Units.
  • TYPE OF APPLICATION: Roller-applied / Spray-applied

 


 

Sheathing Joint Treatments

Sheathing Joint Treatments includes sheathing joint treatments optimized for a variety of conditions and trades. Proper protection of sheathing joints is critical for minimizing the risk of moisture intrusion and unwanted air movement.

Sheathing Joint Treatments is a one-component air and moisture barrier and waterproof material used to seal sheathing joints, seams, cracks, and transitions in above grade wall construction. Rapid drying time will usually allow for same day installation of other Sto air barrier components.

 

  • PERMEABILITY: Vapour Permeable
  • SUBSTRATE TYPE: CMU, Concrete, Brick Masonry, Gypsum Sheathing, Wood, Galvanized metal and Cement based Sheathings.
  • TYPE OF APPLICATION: Apply with a caulking gun.

 


 

Rough Opening Protection

Rough opening protection is a one-component air and moisture barrier used to protect rough openings and for transition detailing in above grade wall construction. Rapid drying time will usually allow for same day installation of windows or top coating with other wall assembly components. Moisture cure properties and resistance to cold conditions help to avoid costly delays related to inclement weather. Liquid-applied technology allows for easy installation at complex geometric conditions such as wood buck or back dams.

 

  • PERMEABILITY: Vapour Permeable
  • SUBSTRATE TYPE: CMU, Concrete, Brick Masonry, Gypsum Sheathing, Wood, Galvanized metal and Cement based Sheathings.
  • TYPE OF APPLICATION: Apply with a caulking gun.
