Fully Accredited Whole Building Air Leakage Testing and Window Testing in Powell
Building Envelope Testing in Powell
Powell’s location in northwestern Wyoming creates a distinctive building environment shaped by cold winters, dry air, strong sunlight, seasonal snow, and significant temperature changes throughout the year. The city sits within the Bighorn Basin between the Absaroka Range and the Big Horn Mountains, where commercial and institutional buildings must perform in a high-desert climate.
Powell also has a building profile that is different from many other Wyoming communities. Agriculture and ranching remain central to the local economy, while Northwest College, healthcare providers, schools, government facilities, retail businesses, and other commercial properties create a varied mix of buildings throughout the area. The City identifies Powell as a regional business community serving a large agricultural area, with a diverse commercial, industrial, educational, and agricultural economy.

Building Enclosure Testing in the Bighorn Basin
Powell lies within a broad basin surrounded by major mountain ranges. The area receives abundant sunshine and has historically depended on irrigation to support agriculture in an otherwise dry environment.
Buildings in this climate can experience cold winter temperatures, dry outdoor air, snow, strong solar exposure, and repeated seasonal temperature changes. These conditions increase the importance of maintaining continuity across exterior walls, windows, doors, roof connections, air barriers, and other enclosure components.
A building envelope functions as a complete system. Even when individual products perform well on their own, gaps or weaknesses at transitions between materials can affect the performance of the completed building.
QED LAB provides building enclosure testing in Powell to evaluate applicable installed systems under specified field conditions.
Window Testing in Powell
Exterior windows are an important part of schools, college buildings, healthcare facilities, offices, retail properties, multifamily developments, and other commercial buildings throughout Powell.
Installed window performance depends on the complete assembly. Frames, glazing, flashing, perimeter sealants, anchors, drainage paths, and connections to surrounding exterior walls can all influence air and water performance.
QED LAB provides professional window testing in Powell for new construction, renovation projects, and existing buildings.
Depending on project requirements, testing can evaluate air leakage, resistance to water penetration, or both. Representative testing can also be useful for projects containing large numbers of similar window installations.
ASTM E1105 Water Penetration Testing
QED LAB provides ASTM E1105 testing in Powell for field evaluation of installed exterior windows, doors, curtain walls, and other applicable assemblies.
During testing, water is applied to the exterior surface while a specified static pressure difference is maintained across the assembly. The test area is then evaluated for water penetration according to applicable requirements.
Window water penetration testing in Powell can support college buildings, schools, healthcare properties, offices, multifamily developments, public buildings, and commercial facilities.
Testing may be incorporated into new construction verification or performed on existing assemblies requiring controlled field evaluation.
Water Penetration Testing in Powell
Powell’s dry climate does not eliminate the possibility of water intrusion.
Rain, melting snow, and wind can expose weaknesses around exterior windows, doors, glazing systems, flashing, joints, penetrations, and transitions between different wall materials.
Water can also travel within concealed building components before becoming visible indoors, making the apparent location of a leak different from the actual entry point.
QED LAB provides water penetration testing in Powell for applicable exterior building assemblies. Controlled testing allows individual components to be evaluated under defined conditions rather than relying solely on naturally occurring weather.
Air Barrier Testing in Powell
Cold winter conditions make enclosure airtightness important for conditioned buildings throughout Powell.
Air leakage can occur around windows, exterior doors, roof connections, wall penetrations, mechanical openings, utility connections, and transitions between construction systems.
QED LAB provides air barrier testing in Powell to evaluate installed air leakage performance.
Field testing generates measurable data that can be compared with project-specific requirements. Air barrier testing can support educational, healthcare, commercial, government, multifamily, and institutional construction.
Commercial Blower Door Testing
QED LAB provides commercial blower door testing in Powell for projects requiring measurement of total building enclosure air leakage.
Specialized equipment creates a controlled pressure difference between the building interior and exterior. The amount of airflow required to maintain that pressure is measured, allowing total enclosure leakage to be quantified.
Commercial blower door testing can support schools, college facilities, medical buildings, offices, public buildings, multifamily developments, and other conditioned properties.
For larger buildings, multiple testing fans may be required depending on building size and project specifications.
Whole Building Air Leakage Testing
Small air leakage pathways can become significant when repeated throughout a complete building enclosure.
Windows, doors, joints, roof transitions, mechanical penetrations, utility openings, and wall interfaces can each contribute to total uncontrolled airflow.
Whole building air leakage testing in Powell evaluates these conditions collectively.
QED LAB uses controlled pressure testing and airflow measurement to provide quantitative information about overall building airtightness. Testing can support commissioning programs, energy-related requirements, construction verification, and other project-specific performance criteria.
ASTM E783 Air Leakage Testing
QED LAB provides ASTM E783 testing in Powell for field measurement of air leakage through installed exterior windows and doors.
A specified pressure difference is established across the test assembly while airflow is measured. The resulting data provides quantitative information about the air leakage performance of the installed component.
Window air leakage testing in Powell can be particularly useful for educational buildings, healthcare facilities, offices, multifamily properties, and other projects containing repeated exterior window assemblies.
ASTM E783 may also be coordinated with ASTM E1105 when both air and water performance require field verification.
Northwest College Building Envelope Testing
Northwest College gives Powell a particularly strong educational and institutional presence.
Founded in 1946, Northwest College serves Park, Big Horn, and Washakie Counties from its main Powell campus. The college reported 1,383 credit students in its 2026 institutional profile and estimated a $76.5 million economic impact across its service area.
The campus includes academic buildings, residence halls, athletic facilities, agricultural facilities, an observatory, administrative spaces, and specialized training buildings.
These facilities can contain repeated windows, large entrance systems, mechanical penetrations, extensive exterior wall areas, and multiple transitions between building materials.
