How WickRight Passive Ventilation®

dries out wet buildings

Installing WickRight Vented Flashings prevents moisture intrusion and exhausts trapped moisture vapor. 

WickRight Keeps New Construction Dry & Dries Out Existing Wet Buildings


How WickRight Passive Ventilation / Vented Flashing works:

• Flashing portion – for example, the vented drip edge that we install under parapet capstones, prevents future moisture intrusion by directing bulk water away from the building.

• Venting portion - of our vented drip edge provides engineered pathways for moisture movement and acts as a rain screen to let trapped moisture vapor leave the parapet wall.

Additional benefits of having WickRight vented flashings installed:

• Sustainable/Green – Wind & Solar Powered!

• Hassle-free – No Moving Parts to break or replace

• Permanent solution – No maintenance required

Mark Kelly satisfied WickRight installer

  • WickRight cured our building's issue. A week after installation, it was dry and the smell was gone.

Passive Ventilation Works – Here's Proof

Capstone Vented Drip Edge, Vented Receiver Clip and Metal Coping Vent
 

  • Introduces 7.2 CFM - cubic feet per minute per linear ft of fresh air flowing over parapet and into wall core with 18 mph wind (avg wind speed Chicago summer day). This helps dry any moisture intrusion that may occur.

  • Produces lift force of 7.87 lbs per foot which pulls moisture vapor out of the wall


  • Solar Drive and Wind promote continuous drying

Do the math - 
Standard 180' perimeter on 3-flat in Chicago

7.2 CFM x 180 linear feet = 1296 CFM!

ASTM & NFA Stats

WickRight Membrane -
Breatheable, yet virtually waterproof!


  • ASTM-E96 - 108 vapor permeability rating


  • Membrane withstands 19.1 psi vertical application of water for 20 minutes

    Note: Membrane is installed         horizontally within the wall assembly - no direct application of water is possible


  • Holds 8 oz of standing water up to 9.5 hours with only .040 grams of seepage

New Construction Application

Restoration Application

Vertical installation of vent materials
on interior side of exterior walls

Benefits:

  • Blocks 100% of moisture intrusion
  • Eliminates condensation build-up
  • Funnels moisture vapor to exit at parapet
  • Acts as a Heat Exchange
  • Translates to substantial cooling energy savings - 15º lower temperature on interior side of CMU wall


Client in Tampa –
"I was sitting on the roof and the steam coming out of the parapet actually  burned my legs."

Installation Monitoring



WickRight has monitored 15 buildings with Capstone Vented Drip Edge/Vented Receiver Clip or Metal Coping Vent and Low-Slope Roof Vent installations 36 months post installation.


Typical Results:

  • Elimination of leaks at ceiling/floor levels within 1 week
  • Improvement of air quality/elimination of smells within 2-3 weeks
  • Significant reduction of indoor humidity readings within 3-4 weeks
  • Improved HVAC system performance and reduced heating and cooling bills compared to previous season

WickRight crush testing shows it can hold over 300 lbs

Other Testing Results

Practical, Durable Designs


  • Crush testing - Capstone Vent Drip Edge withstands up to 323 lbs of pressure psi

 

  • Capstone Vented Drip Edge, Vented Receiver Clip, Clay Coping Vent and Metal Coping Vent work on all parapet widths - Capstone filler is available for installation in center of wall


  • Fascia/Perimeter Vent designs available for installation on full and partial roof tear offs


  • Hip & Valley Vent - 2-in-1 solution - use on hips and valleys, makes it easier to work on tight multi-roof lines and reduces materials storage needs


  • Do not use WickRight products with primers or sealants that contain Xylene

WickRight Passive Ventilation is always evolving. We now offer engineered vapor release pathways for buildings with issues stemming from:

  • Capstones
  • Metal Copings 
  • Clay Copings
  • Junction of the parapet wall and roof
  • Interstitial roof space
  • Trusses embedded in masonry
