Basic Use:
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.
New construction or retrofit.
For commercial, industrial and institutional applications.
Composition and Materials:
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.
Wet Thickness:
1 mm (40 mils)
Coverage:
Roll Width - 457 mm (18") x 22.86 m (75')
Coverage - 10.5 m² (112.5 sq. ft.)
Net Coverage - 9.3 m² (100 sq. ft.)
Coverage based on 50 mm (2") side and end laps
Colour: White
Limitations:
Not designed to perform as a permanently exposed membrane. Product
designed to withstand job site exposure for six weeks, however,
good practice calls for covering as soon as possible.
Applicable Standards:
Meets and exceeds National Research Council (NCR) Type III Air
Leakage requirements. Meets the requirements of ASTM E-96 Type
I water vapour permeance. See Physical Properties Chart.
Preparatory Work:
Refer to Examination section of specification for substrate requirements
by others (new construction).
Under the work of the air barrier section of work, the following
preparatory requirements include:
- Ensure that all surfaces are dry, smooth and regular, free
of all voids, defects and excessive dust.
- Concrete surfaces must be smooth and without large voids,
spalled areas or sharp protrusions. Concrete must be cured a
minimum of 14 days and must be dry before Rub-R-Wall SA is applied.
- Prime all surfaces to receive Rub-R-Wall SA using Rub-R-Wall
Primer applied by roller, brush or spray equipment at a rate
of 2-6 m²/L (100-300 sq. ft./gallon) depending on porosity
and texture of surface. Allow primer to dry 30 minutes prior
to membrane installation. Ensure that all primed surfaces receive
Rub-R-Wall SA in the same day (or re-priming will be required).
Methods: Refer
to guide specification for detailed application information.
Typically begin membrane installation at the base of all wall
areas. Rub-R-Wall SA must be lapped a minimum of 50 mm (2”)
on both side and end laps. Position membrane for alignment, roll
back, remove protective film and press firmly in place. The membrane
shall be firmly pressed in place by means of a hand roller, thereby
ensuring continuous contact with the substrate. When using membrane
with brick ties, position membrane, press in place and cut for
ties or projections. Seal around any openings with Rub-R-Wall
Mastic.
Rub-R-Wall SA is applied within the recommend application temperature
range (may be applied successfully at temperatures as low as -6°C
(22°F)).
A spray or board type cavity wall insulation is adhered to the
Rub-R-Wall SA to prevent convection currents occurring behind
the insulation. Wedges or clips are normally used to secure the
insulation.
