Air Barriers



Rub-R-Wall Airtight
Primarily intended as a non-accessible air/vapour barrier for all types of cavity wall construction, Rub-R-Wall Airtight is a 100% rubber copolymer liquid applied air/vapour barrier membrane (hydrocarbon polymers in hydrocarbon solvents) that is spray applied to the substrate.
Transition joints in the substrate to receive Rub-R-Wall Airtight are first sealed with Rub-R-Wall SA, a self-adhering, cold applied composite sheet membrane (transition strip). These strips, approximately 150 mm (6") wide, are located at beams, columns, changes in substrate material, and similiar joints or connections to provide continuity of the air/vapour barrier assembly.
Rub-R-Wall Airtight meets all of the principal requirements and design criteria for a properly constructed air barrier for the building envelope, namely:
-
resistance to air flow;
-
structural soundness, capable of resisting wind and other loads, over its expected life span;
-
continuity throughout the building envelope;
-
be permanent if concealed.

Green Code
Primarily intended as a non-accessible air/vapour barrier for all types of cavity wall construction, Green Code is a 100% rubber copolymer liquid applied air/vapour barrier membrane (hydrocarbon polymers in hydrocarbon solvents) that is spray applied to the substrate by manufacturer approved applicators.
Transition joints in the substrate to receive Code Green are first sealed with Rub-R-Wall SA, a self-adhering, cold applied composite sheet mebrane (transition strip). These strips, approximately 150 mm (6") wide, are located at beams, columns, changes in substrate material, and similiar joints or connections to provide continuity of the air/vapour barrier assembly.
Green Code meets all of the principal requirements and design criteria for a properly constructed air barrier for the building envelope, namely:
-
resistance to air flow;
-
structural soundness, capable of resisting wind and other loads, over its expected life span;
-
continuity throughout the building envelope;
-
be permanent if concealed.

Graywall Vapour Permeable Air Barrier
Primarily intended as a non-accessible air barrier for all types of cavity wall construction. Graywall provides an air barrier on exterior construction surfaces such as masonry, concrete and drywall systems utilizing an interior vapour barrier such as polyethylene film where the entrapment of water vapour is to be avoided. Can be installed on the cold side of the wall assembly without trapping moisture.
Graywall is a 100% rubber copolymer liquid applied air barrier membrane that is designed to resist air leakage when applied to construction surfaces while remaining permeable to the passage of water vapour. Graywall is spray applied to the substrate by manufacturer approved applicators.
Transition joints in the substrate to receive Graywall are first sealed with Rub-R-Wall SA a self-adhering, cold-applied composite sheet membrane (transition strip). These strips, approximately 150 mm (6”) wide, are located at beams, columns, changes in substrate material, and similar joints or connections to provide continuity of the air barrier assembly.
Graywall meets all of the principal requirements and design criteria for a properly constructed air barrier for the building envelope, namely:
-
resistance to air flow
-
structural soundness, capable of resisting wind and other loads, over its expected life span
-
continuity throughout the building envelope
-
be permanent if concealed

Rub-R-Wall SA
Primarily intended as a non-accessible air barrier for all types of cavity wall construction e.g. over exterior face of inner wythe of masonry cavity wall, Rub-R-Wall SA can also be used in conjunction with Advanced Coatings Spray-Applied Membranes as a transition membrane. Rub-R-Wall SA is also used for tying into metal on curtain walls, windows and door frames.
Rub-R-Wall SA is a self-adhering, cold applied composite sheet membrane comprised of rubberized asphalt integrally bonded to a film of high density cross-laminated polyethylene for a minimum thickness of 1.0 mm (40 mils).
Rub-R-Wall SA meets all of the principal requirements and design criteria for a properly constructed air barrier for the building envelope, namely:
-
provides a continuous, durable air barrier;
-
resistance to air flow;
-
resistance to vapour drive;
-
provides an effective drainage plain in a cavity (secondary drainage) wall;
-
structural soundness, capable of resisting wind and other loads, over its expected life span;
-
continuity throughout the building envelope;
-
provides a structurally sound air barrier capable of resisting wind, stack effect and mechanical pressurization.
