Fully Accredited Whole Building Air Leakage Testing and Window Testing in Billings
Building Envelope Testing in Billings, MT
Billings is Montana’s largest commercial center, with a mix of healthcare facilities, schools, office buildings, hotels, multifamily developments, retail properties, warehouses, and industrial facilities spread throughout the city and surrounding Yellowstone County. Buildings in this region must perform through cold winters, snow, wind, summer heat, and significant seasonal temperature changes.
QED LAB provides building envelope testing in Billings, Montana, helping contractors, developers, architects, consultants, and building owners evaluate how exterior enclosure systems perform after installation.
Our capabilities include air barrier testing, commercial blower door testing, whole-building air leakage testing, window and curtain wall testing, water penetration testing, AAMA testing, ASTM testing, infrared thermography, and building enclosure commissioning support.
Whether testing is required by project specifications, commissioning requirements, construction quality-control procedures, or an investigation into an existing building problem, QED LAB provides field testing and diagnostic information that can help project teams better understand enclosure performance.
Commercial Building Envelope Testing in Billings
A commercial building envelope includes the systems separating conditioned interior areas from the outdoor environment.
These systems can include:
- Exterior walls
- Air barriers
- Windows
- Doors
- Curtain walls
- Storefront systems
- Roofing transitions
- Waterproofing
- Sealants
- Flashing
- Penetrations
- Interfaces between different materials
Even when individual products meet their intended specifications, problems can develop where multiple enclosure systems come together.
A window may perform properly while water enters around its perimeter. An otherwise continuous air barrier may contain leakage at penetrations, roof-to-wall transitions, or connections between materials. Sealants and flashing details can also perform differently from one installation location to another.
Field testing allows Billings construction teams to evaluate these conditions under controlled test procedures.
Air Barrier Testing in Billings, MT
Air barriers are intended to limit uncontrolled airflow through the exterior enclosure.
Gaps and discontinuities can contribute to drafts, unwanted energy loss, moisture movement, pressure problems, and inconsistent indoor conditions.
QED LAB provides air barrier testing in Billings for commercial buildings and larger projects requiring verification of enclosure airtightness.
Testing may be performed during new construction, as part of commissioning, for quality assurance, or during an investigation of an existing building.
Depending on the project, testing can provide both an overall measurement of air leakage and additional information that helps identify areas where unwanted leakage may be occurring.
Commercial Blower Door Testing in Billings
Blower door testing is not limited to residential homes.
Commercial and institutional buildings can be evaluated using calibrated fan systems capable of creating a controlled pressure difference across the building enclosure.
QED LAB provides commercial blower door testing in Billings, MT, including testing for larger buildings where project teams need to quantify overall air leakage.
Depending on project requirements, procedures may reference standards such as ASTM E779 or ASTM E1827.
Testing a large building requires more preparation than testing a typical residence. Building size, exterior openings, pressure zones, mechanical systems, doors, weather conditions, and enclosure configuration may all influence the test setup.
QED LAB works with project teams before testing to establish the appropriate procedure and help prepare the building.
Whole-Building Air Leakage Testing
Whole-building air leakage testing evaluates the enclosure as a complete system rather than focusing only on one window, wall section, or other component.
During testing, the building is intentionally pressurized or depressurized while calibrated equipment measures the airflow necessary to maintain the required pressure difference.
Results can then be compared with applicable project criteria.
If measured leakage exceeds the desired level, additional diagnostic techniques may be useful for finding specific leakage locations.
This approach can be particularly useful for commercial buildings in Billings because it provides measurable performance information for the completed enclosure.
Window and Curtain Wall Testing in Billings
Windows and other fenestration assemblies contain many joints and transitions where air or water leakage can develop.
QED LAB provides window testing in Billings, Montana, along with field evaluation of storefronts, curtain walls, doors, and related exterior assemblies.
Potential problem areas can include:
- Window perimeter seals
- Curtain wall joints
- Storefront framing
- Gaskets
- Sealants
- Flashing
- Rough openings
- Material transitions
- Installation details
Testing representative installations during construction can help identify problems before the same detail is repeated across a larger portion of the building.
This can be especially valuable on hotels, multifamily developments, healthcare buildings, office properties, schools, and other projects containing large numbers of windows or glazed assemblies.
AAMA 501.2 Hose Nozzle Testing
AAMA 501.2 testing is commonly used as a field quality-control procedure for investigating joints and sealant details in installed storefront and curtain wall systems.
A controlled stream of water is applied to targeted exterior joints while the interior is monitored for leakage.
Because the test can focus on relatively small sections of an assembly, AAMA 501.2 can be useful when a Billings project team needs to isolate a specific joint, gasket, sealant condition, or installation detail.
Testing may be incorporated into construction quality-control programs or used when investigating an existing water intrusion concern.
AAMA 502 and AAMA 503 Field Testing
QED LAB can support AAMA field testing in Billings where project specifications require evaluation of installed fenestration systems.
AAMA 502 procedures may be used for field testing of installed windows and doors for air leakage and water penetration performance.
For storefronts, curtain walls, and similar commercial fenestration assemblies, AAMA 503 procedures may apply depending on the project requirements.
Field testing is important because laboratory product performance does not automatically guarantee identical performance after installation.
Perimeter seals, flashing, rough openings, anchorage, adjoining materials, and workmanship all influence how the completed assembly performs as part of the actual building enclosure.
ASTM E1105 Water Penetration Testing
ASTM E1105 is widely used to evaluate water penetration through installed exterior windows, curtain walls, and doors.
During testing, water is applied to the exterior of the assembly while equipment creates a controlled pressure difference across the test area.
The interior side is then monitored for water penetration.
QED LAB provides ASTM E1105 testing in Billings for projects requiring field verification of installed fenestration performance.
The procedure may be used during construction, as part of a commissioning program, or when investigating an existing building with reported water leakage.
ASTM E331 Water Penetration Testing
ASTM E331 is another procedure used to evaluate water penetration through exterior wall or fenestration assemblies under a uniform static air pressure difference.
Depending on the assembly, project specifications, and testing purpose, QED LAB can support water penetration testing using applicable ASTM procedures.
The appropriate testing standard should be based on the project requirements rather than selecting a method solely because it is commonly used.
Water Intrusion Investigation in Billings
Not all water leakage problems appear immediately after construction.
An existing commercial building may experience leakage only during certain storms, wind directions, snowmelt conditions, or combinations of weather.
Water can also travel inside wall assemblies before becoming visible indoors, meaning the location of an interior stain may not identify the actual entry point.
QED LAB can use controlled field testing and diagnostic methods to help isolate suspected water entry locations.
Potential sources can include window perimeters, storefront joints, curtain wall interfaces, sealant failures, flashing, penetrations, and transitions between enclosure systems.
For building owners and facility managers in Billings, testing can provide more useful information than relying on visual observation alone.
Building Enclosure Commissioning in Billings
Building enclosure commissioning can help project teams establish performance expectations and verify enclosure construction throughout the design and construction process.
Instead of waiting until completion to discover a recurring installation problem, commissioning can involve reviewing project requirements, observing construction, coordinating testing, and documenting performance at key stages.
QED LAB supports building enclosure commissioning in Billings through field testing and verification services.
Testing may focus on air barriers, windows, storefronts, curtain walls, water penetration resistance, whole-building airtightness, or other enclosure systems identified in the project requirements.
Testing During Construction Can Identify Problems Earlier
The timing of testing can have a major impact on its usefulness.
Testing representative assemblies early in construction gives project teams an opportunity to identify issues while installation methods can still be adjusted.
For example, discovering a recurring window perimeter leak after several installations is very different from finding the same problem after dozens or hundreds of windows have been installed and interior finishes are complete.
Early field testing can help contractors, architects, consultants, and owners evaluate workmanship before problematic details are repeated throughout the project.

When Should Building Envelope Testing Be Scheduled?
Testing should ideally be discussed before the enclosure is completely finished.
Early coordination gives the project team time to review specifications, confirm required standards, identify representative testing locations, prepare assemblies, and coordinate testing with the construction schedule.
However, QED LAB can also assist when construction is already underway or when an existing Billings building has developed an air leakage or water intrusion problem.
When requesting testing, useful project information can include the building type, approximate size, construction phase, applicable specification sections, required standards, number of test locations, and anticipated project schedule.
