RECENT PROJECT HIGHLIGHTS

On-site evaluations of installed products, validation of a purchased envelope package, investigation of issues ranging from water leaks to excessive energy costs - our portfolio of work tells the story.

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.

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.

NOTEWORTHY FROM HTL

Independent studies, industry papers, slideshows, video presentations, and other content benefiting those in the industry with the patience to read a full five pages, and simple diagrams for everyone else.

  • Meet the New UI Design
    ASTM E783 AND ALL-GLASS FACADES

    Industry-wide, invalicd 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 propery's performance.

  • A LOOK INSIDE THE Workspace
    NOTE FROM THE FOUNDER

    A yearly note to re-cap adventures and observations from 2022. Longform elaborations roughly equivalent to a cardboard sign stating "the quality control end is nigh."

  • Inspiration of UX design
    FGIA '22 PRESENTATION

    A presentation and demonstration of the basic concepts to look for when observing or performing ASTM E783 and ASTM E1105 tests.
