Flashing Comparison and Capabilities

1
Flashing Tape Applications
Performance Requirements

• Why Flashing Tape?
• Call backs-The average builder spends 500 -
  1500 per home in moisture related call backs.
  Builders are starting to specify the use of
  flashing tapes as a preventative measure
• Litigation- mold and damage claims (esp. CA,
  Northwest and Southeast)
• Building codes- requiring use of flashing
  materials (CA, FL, Mecklenburg County, NC,
  International Residential Code)
• Consumer awareness- concern about energy
  consumption, building durability, water damage
  and mold development
• Mfr. recommendations- Window and door
  manufacturers starting to recommend self adhered
  flashing tapes, sometimes by name

• Cold weather adhesion
• Thermal resistance/service temperature
• Adhesion to building materials
• Lap Adhesion
• Water Resistance Water Intrusion (wind driven
  rain), water vapor
• Tensile Strength
• Nail sealability
• Elongation
• Test Standards (see Appendix)
• AAMA 711-05
• ASTM E2112-06
• ICC AC148

Growing opportunity with increasing test and code
standardization

Why choose Butyl Rubber Adhesive?

• Sealant Compatibility-
• Butyl rubber adhesive contains no VOCs- VOCs
  (volatile organic compounds) present in SBS
  asphalt formulations can react with the solvents
  in caulking and sealant compounds causing
  degradation of both systems. This compromises the
  seal integrity, threatening the weather
  resistance of the installation.
• Ease of use- Contractors and installers can use a
  wide variety of caulking and sealants with
  confidence about the compatibility of the
  materials.
• Broad Temperature performance
• Cold Weather Adhesion- Butyl rubber stays pliable
  at low temperatures and can be formulated for
  excellent anchorage to a variety of building
  materials at temperatures as low as 0F. SBS
  asphalt becomes brittle below 40F reducing
  ability to stick to surfaces.
• High Temperature Stability- Butyl rubber has high
  cohesive strength and structural integrity that
  support the adhesive at elevated temperatures as
  high as 180F. SBS asphalt has a narrow
  temperature range and will often run or ooze at
  elevated temperatures.

Butyl Rubber- Superior Performance Over the Life
of the Installation

Why choose Butyl Rubber Adhesive?

• Adhesion- Butyl rubber adheres strongly to a
  variety of building materials including vinyl,
  wood, aluminum, nonwoven and polymeric membranes,
  and masonry.
• Durability-
• Long Term Pliability- Butyl rubber maintains its
  flexibility over the life of the application
  providing excellent resistance to ozone and
  weathering. Solvents in SBS asphalt formulations
  can dissipate over time causing the adhesive to
  dry out and compromise seal integrity.
• Impermeable- Butyl rubber provides an
  impenetrable barrier to water, air and water
  vapor to protect spaces from environmental
  exposure.

Flashing Tape Adhesive Comparison
Butyl Rubber
Butyl Rubber

• Synthetic rubber developed in the 1940s
• Air tight and gas impermeable
• Excellent moisture resistance, provides a
  permanent, flexible, watertight seal
• Good weathering and ozone resistance
• Provides aggressive chemical and mechanical
  adhesion to a variety of clean, dry surfaces

• Formulated for extreme environments
• Remains highly stable and intact in heat up to
  180F
• Exceptional cold weather adhesion
• Does not delaminate or stain substrates
• Contains no solvents or VOCs
• Compatible with some caulking chemistries

SBS Asphalt
SBS Asphalt

• Asphalt adhesives flow at high temperatures
• Will become brittle at cold temperatures
• May contain solvents and VOCs, becoming brittle
  over time resulting in breakage and loss of
  adhesive properties
• Seal integrity susceptible to water and air leaks
  due to adhesive breakdown
• May stain substrates

• By-product of petroleum refining
• Composition is variable depending on crude oil
  source
• Sensitive to oxidative degradation of low
  molecular weight components due to heat and UV
• Not compatible with some caulking chemistries

Flashing - Window Flashing Tape Market

• Why Window Flashing Tape?
• Also used in new home additions and remodeling

• Not Just for Windows!
• Beam Deck Joists
• Dryer Vents
• Utility Boxes
• Flashing Collars
• Pipe Conduit
• Roof Kickouts

Window flashing tape is a sizeable, growing
market!

International Residential Code

• International Residential Code
• Initially developed in 2000 to create a
  comprehensive, stand-alone residential code by
  members of the International Code Council
• R703.8 Flashing Approved corrosion resistant
  flashing shall be provided in the exterior wall
  envelope in such a manner as to prevent entry of
  water into the wall cavity or penetration to the
  building structural framing components.
• Seven locations specified
• Top of exterior windows and doors
• Intersection of chimneys or other construction
  with frame or stucco walls
• Under the ends of masonry, wood or metal copings
• Continuously above all projecting wood trim.
• Where exterior porches, decks or stairs attach to
  a wall or floor assembly of wood construction
• At wall and roof intersections
• At built-in gutters
