The water-resistive performance of the building envelope is critical for structural integrity (reference nearly every recent catastrophic building collapse), indoor air quality (organic growth formation), humidity/moisture control, component deterioration and rot, etc. HTL has a complete suite of field tests to evaluate a building's water-resistive performance with lab-quality data and comprehensive report deliverables.

On-Site Mockup
Save cost and improve awareness of critical system detailing and transitions among on-site personnel. Rather than a remote location with, often times, little involvement from key on-site installers and documentatation of critical detailing/remediation lost in the subsequent reporting - consider an on-site or local "mini-PMU" with participation from all building envelope trades (e.g. block, framing, sheathing, vapor barrier install, rain screen, metal panels, windows, etc.).
