VaproShield | Breathable WRB/Air Barriers

By MaxClad
Website

VaproShield offers high performance, vapor permeable, water resistive barriers (WRB) and air barrier (AB) systems. Their flashing and rain screen accessories create a total solution-based approach to protecting the building envelope.

VaproShield self adhered products are part of complete WRB / AB Systems. MaxClad provide three products as part of this system: RevealShield SA (Self Adhered) ,WrapShield SA (Self Adhered) and Slopeshield Plus SA.

Revealshield SA (Self Adhered) is used where one of the following requirements is a prerequisite for a particular project :

  • The rainscreen is open jointed
  • There is a likelihood that the rain screen install could be delayed [ Revealshield SA may be expose for up to 12 months.
  • There are specific fire performance requirements for the WRB / AB.

These systems can be employed in both Commercial and Residential construction projects.For commercial construction the size and area employed of Revealshield SA was very large at Commercial Bay. The image attached shows the sheathing covered with black Revealshield SA prior to the stone rainscreen façade being installed.

For residential construction the small house (Skylark Cabin) built near Twizel is an example of how the product works in extreme conditions being located in one of the most exposed wind sites in the country. In this case Revealshield SA is critical to the performance of the façade as the rainscreen is timber planks (with gaps between the planks over horizontal timber battens. The timber battens are screwed to the structure through Vaproshims SA which seals all of the fixings and provides a drainage and ventilation pathway behind the timber planks.

Benefits:

  • Breathable and Air Tight – protecting the building envelope by letting vapor pass through but not air or water.
  • Energy Saving – decreases air movement in and out of the building envelope, saving energy for the life of the building.
  • Moisture Management – VaproShield membranes breathe like a frog's skin, helping to dry-out substrates, drastically reducing the incident of mold, mildew and rot.
  • Works with Virtually all Substrates.
  • Compatible with Diverse Veneers and Cladding – Including open joint facades, fiber cement, ACM, stucco, brick and stone.

Complete WRB/Air Barrier System:

VaproShield’s membranes, rain screen design components, and rough-opening flashing materials are designed and tested to work together—reducing your liability and potential moisture related repairs.

The solution-based approach to the building envelope offers:

  • Increased Contractor Profitability - lower installed cost, lesss inventory, minimal training.
  • Phase Construction Friendly Installation - apply in extreme conditions, stay on your schedule--not Mother Nature's.
  • Multi-substrate/Cladding Compatible - install a single WRB/Air Barrier system, no need for multiple supplies.
  • Crew Safety - zero VOC’s, no toxins, no specialized mobilizations.

Multiple Cladding, Substrates, Insulation: One WRB/Air Barrier Solution

Mass Timber Installation

SlopeShield Plus Self-Adhered roofing underlayment offers permanent mass timber roof deck/floor deck protection by allowing vapor to pass through (breathable) but not air or liquid water.

WallShield IT Integrated Tape water resistive barrier (WRB) membrane offers mass timber post, column, and beam protection by allowing vapor and air to pass through but not liquid water.

PanelShield SA is a permeable polyester air barrier (AB) and water resistive barrier (WRB) sheet membrane offers permanent protection for exterior walls by allowing vapor to escape through but not air or liquid water.

BASIC USE

SlopeShield Plus SA is installed on the roof deck/floor deck as the structure is erected and taped using VaproTape on the seams. The underlayment can be installed on a low slope (1/4":12 to 2:12) assembly or a steep slope (2:12 or greater) assembly.

WallShield IT is wrapped around posts/columns and beams and uses VaproTape at the seams.

PanelShield SA is designed for exterior walls with rainscreen cladding materials. VaproShield offers additional WRB air barrier membranes for walls including open joint cladding, see individual product data sheets.

MATERIALS

COMPATIBLE SUBSTRATES

All mass timber types:

  • Cross-laminated timber (CLT)
  • Nail-laminated timber (NLT)
  • Dowel-laminated timber (DLT)
  • Vertically laminated veneer lumber (LVL)
  • Glue-laminated timber (GLT)
  • Laminated strand lumber (LSL)
  • Timber-concrete composites (TCC)
  • Parallel strand lumber (PSL)
  • Mass plywood panel (MPP)

INSTALLATIONSTORAGE AND HANDLING

Store materials on end in original packaging at temperatures between 40°F and 120°F (4.4°C and 48.9°C). Protect materials from direct sunlight and inclement weather until ready for use.

SAFETY

CAUTION: Release liners are slippery. To prevent injury, liner should be removed from under foot as soon as membrane is installed and disposed of properly.

Work crews are safe around VaproShield membranes they contain zero VOCs or toxins.

Persons who access any roofs, involved with roof construction, repair or maintenance shall use appropriate personal protective equipment including, but not limited to, hard hats, eye protection, and leather gloves and must be trained on safe practices relevant to their work.

Where the use of ladders, scaffolds, platforms, or temporary floors are utilized, safety lines and safety harnesses shall be used. Please access the OSHA Web site at www.osha.gov, contact your local OSHA office, or visit the local federal bookstore to obtain the most current information on OSHA 29 CFR 1926.

PREPARATION

For self-adhered membranes all surfaces must be dry, sound, clean, “as new” condition, and free of oil, grease, dirt, excess mortar or other contaminants detrimental to the adhesion of the roofing underlayment or WRB air barrier. Fill voids and gaps in substrate greater than ½” (12.7 mm) in width to provide an even surface.

LIMITATIONS

SlopeShield Plus Self-Adhered should be covered within 180 (6 months) of installation with permanent roofing/flooring material. Minimum recommended application temperature of 20˚F (- 6.0˚C) and rising.

PanelShield SA should be covered with cladding within 12 months of field assembly. Minimum field assembly recommended installation temperature of 20˚ F (- 6.0˚ C) and rising.
