Building Envelope Testing Services

Building envelope testing expert performing ASTM field tests on commercial façade

Building envelope testing ensures that your structure’s exterior systems are sealed against air, water, and thermal intrusion. At Inspec, we follow ASTM and industry best practices to deliver testing that’s accurate, efficient, and code-compliant—giving you clarity and confidence before occupancy or closeout.

What is Building Envelope Testing?

Envelope testing evaluates how well your walls, windows, roofs, and joints resist air and water penetration. Using blower doors, infrared thermography, and spray racks, we detect problems like leaky windows, failed insulation, and unsealed penetrations—before they cause expensive damage.

Why Test the Building Envelope?

  • Ensure compliance with IECC, LEED, and local codes
  • Identify issues before occupancy, turnover, or warranty expiration
  • Prevent moisture intrusion, mold, and air leaks
  • Validate energy performance and insulation effectiveness
  • Support Building Envelope Commissioning (BECx) and inspections

Our Envelope Testing Services Include:

  • ASTM E1105 Water Penetration Testing (spray rack method)
  • ASTM E783 Air Leakage Testing (fan pressurization method)
  • Blower Door and Duct Leakage Testing (residential/commercial)
  • Infrared Thermal Imaging for insulation and thermal bridging
  • Roof Moisture & Insulation Scanning

Case Study: LEED Project Envelope Validation

Project: 15-story mixed-use building in downtown Minneapolis

Need: Confirm air and water tightness for LEED certification

Solution: Blower door and spray rack testing following ASTM E779 and E1105

Result: Identified flange failure at glazing system, corrected during construction, passed retest, and secured LEED envelope credits
