PROVEN BUILDING ENVELOPE SOLUTIONS:
Our Recent Projects

At Hightower Labs, we specialize in evaluating and improving the performance of building envelope systems. Our completed projects, some of which are showcased here, reflect our commitment to precision, problem-solving, and delivering actionable insights for building owners, developers, and design professionals. Thorough, comprehensive analysis of building envelope systems for risk assessment

On-Site Evaluations & Performance Validation

We conduct comprehensive on-site evaluations of installed building envelope components, ensuring they meet design specifications, performance criteria, and long-term durability expectations. Our assessments provide clients with clear documentation and expert recommendations to validate completed envelope scope packages before project closeout.


Leak Investigations & Water Intrusion Diagnostics

Water infiltration can be costly and disruptive. Our team specializes in identifying and diagnosing water intrusion issues, whether due to construction defects, material failures, or unforeseen environmental factors. Through field testing, forensic analysis, and advanced diagnostic techniques, we deliver clear findings and effective remediation strategies.



New Construction & Retrofit Assessments

For both new and existing buildings, our evaluations help stakeholders mitigate risks and optimize envelope performance. We analyze air, water, and thermal barriers to ensure proper integration and long-term resilience. Our work supports developers, architects, and contractors in refining construction details and ensuring compliance with energy codes and performance standards.


Supporting Litigation & Remediation Efforts

When envelope failures result in costly disputes, our forensic investigations provide clarity. We assist property owners, law firms, and insurance providers with detailed analysis and expert reporting to support claims, litigation, or remediation planning. Our unbiased, data-driven approach ensures stakeholders have the technical insights they need to resolve complex envelope-related issues.



Let's Work Together

Fully understanding the air, water, and thermal performance of your building envelope is a critical component of investment maintenance. Contact Hightower Labs, Inc. today to learn how our specialized expertise can support your building assessment or commissioning program.

PREMIUM BUILDING ENVELOPE QAQC

We're a Midwestern building envelope QAQC services company founded on the guiding principle that future occupants and stakeholders of the built environment are owed our best efforts in design and execution. Our work keeps the future in mind, and serves the people occupying that future.

htl
AIR
Fenestration testing via ASTM E783, and air barrier testing to validate a specimen's complete or compartmentalized thermal envelope assembly.
ASTM E779, D4541, E1186, E1827, etc.
htl
WATER
Water testing to validate the water-resistive properties of envelope, or the components comprising the envelope.
ASTM E1105, AAMA 501.2, etc.
htl
COMPREHENSIVE ANALYSIS
In situ testing, air/water/thermal diagnostics, forensic investigation, document review, to provide a clear, comprehensive study of a building envelope's air/water/thermal/energy performance.

    ASTM E783 AND ALL-GLASS FACADES

    Industry-wide, invalid and improperly executed ASTM E783 test data are not providing a reliably accurate accounting of the building's air-tightness on window wall and curtain wall systems comprising the majority of envelopes built this century and, consequently, building stakeholders are blind to their property's performance.

    BEAM03 PROCEDURE INTRODUCTION

    The BEAM03 procedure introduces a novel approach to evaluating building envelope water resistivity, addressing critical gaps in traditional QAQC practices. BEAM03 delivers reliable, repeatable data for assessing large-scale envelope performance, including complex geometries and system transitions.
