Performance and Diagnostic Testing for Windows, Glass and Façade
Performance and Diagnostic Testing for Windows, Glass and Façade

When there is a failure in a building envelope, figuring out what went wrong requires a scientific approach. Finding the truth behind a leak means asking the right questions—with appropriate testing to explore windows, curtainwalls, sealants, masonry, and other components. The faster you determine the cause, the less money it will cost to solve the problem.
At Façade Consultants, we determine the correct tests for the situation at hand.
Areas of exploration might include:
Water Penetration | Air Infiltration | Insulation Failure | Condensation/Dewpoint
Hands-On Investigation Solves Tough Problems
In addition to standard lab testing, Façade Consultants offers a “mobile lab” service to perform many kinds of testing on-site—right where the problem is happening.
