Window Testing

Window Testing, also known as Fenestration Water Intrusion Testing, can be utilized for both new construction or window installation on existing buildings. 

Window Testing for New Construction

For new construction, BEE requires the window and door submittal package in advance of construction.  Typically, BEE will provide a pre-test site visit to coordinate logistics with the project team.  During this meeting, BEE will confirm the following items:

  • Installation of the Weather Resistive Barrier (WRB) membrane around the fenestrations to be tested is complete. 
  • Confirmation that the window & door installations are complete.
  • Confirmation that the air barrier sealants are in place.   

Window Testing for Existing Buildings

For new or existing buildings, BEE’s team will need to establish the following:

  • Water source.
  • Confirm adequate water pressure.
  • 110 power source nearby. 
  • Confirm exterior access to each of the specimens to be tested is available.

What Happens on the Day of Testing?

  • On the day of testing, BEE’s team will construct and seal a chamber on the interior of the building around the fenestration to be tested.  A fan will be attached to the chamber to exhaust air from the chamber at a rate required to maintain the test pressure across the specimen.
  • On the exterior of the window or door, BEE’s team will set up a calibrated spray rack at the exterior face of the specimen to be tested.  This test has water spraying at the window or door at a specified rate and pressure from the exterior to simulate a wind driven rain.  This simulates the wind pressure that could be forced upon the unit from natural winds.  

What Happens After the Test?

After the testing is complete, BEE will generate a written report with the window test results.
