Fully Accredited Whole Building Air Leakage Testing and Window Testing in Marietta
Building Envelope Testing in Marietta, GA
Commercial buildings throughout Marietta depend on exterior enclosure systems that can control air leakage, water intrusion, heat, and moisture while supporting long-term building performance. Windows, exterior walls, roofs, doors, air barriers, waterproofing systems, storefronts, and curtain walls must work together as one continuous enclosure rather than as separate components.
QED LAB provides building envelope testing in Marietta, Georgia, for new construction and existing commercial properties throughout Marietta, Cobb County, and the Northwest Atlanta metro. Our testing capabilities include commercial blower door testing, whole-building air leakage testing, air barrier testing, window and curtain wall testing, AAMA field testing, ASTM water penetration testing, infrared thermography, water intrusion diagnostics, and building enclosure commissioning support.
Whether a project is located near Downtown Marietta, Marietta Square, Cobb Parkway, I-75, East Cobb, West Cobb, or elsewhere in Cobb County, QED LAB can develop a field-testing scope based on the building, project specifications, and required performance criteria.
Commercial Building Envelope Testing in Marietta
Building-envelope problems frequently develop where different materials and systems meet. A wall assembly may be properly constructed while an adjacent window perimeter contains a gap. An air barrier may perform across large wall areas but lose continuity around penetrations, exterior doors, roof connections, or changes in construction.
These conditions can be difficult to evaluate through visual inspection alone. QED LAB provides commercial building envelope testing in Marietta and Cobb County to measure actual field performance and help project teams determine whether installed systems are meeting applicable requirements.
Testing may be incorporated into new construction quality assurance, building enclosure commissioning, project specification compliance, or an investigation into existing air and water leakage. Depending on the project, QED LAB can evaluate individual exterior assemblies or overall whole-building performance.
Air Barrier Testing in Marietta, GA
A continuous air barrier limits uncontrolled airflow between conditioned interior spaces and the exterior environment. When discontinuities are present, unwanted air can move through wall assemblies, roof transitions, windows, doors, mechanical penetrations, and other openings.
QED LAB provides air barrier testing in Marietta, Georgia, for commercial and larger-building projects. Testing can help quantify enclosure leakage and determine whether a building satisfies applicable airtightness requirements. If results indicate excessive leakage, diagnostic techniques can help identify areas where air is moving through the enclosure.
For offices, healthcare facilities, schools, hotels, multifamily developments, and other conditioned buildings throughout Cobb County, controlling uncontrolled airflow can contribute to better energy performance, moisture management, indoor comfort, and more predictable operation of mechanical systems.
Commercial Blower Door Testing in Marietta
Blower door testing isn’t limited to residential construction. Commercial buildings can be evaluated using multiple calibrated fan systems capable of creating a controlled pressure difference across a much larger exterior enclosure.
QED LAB provides commercial blower door testing in Marietta, GA, including whole-building air leakage testing for projects throughout Cobb County. Depending on project requirements, testing may reference procedures such as ASTM E779 or ASTM E1827.
Commercial testing requires careful preparation. Exterior openings, HVAC equipment, intentional penetrations, temporary construction conditions, building size, internal pressure zones, and the level of enclosure completion can all influence the procedure. QED LAB works with project teams before testing to establish preparation requirements and coordinate an appropriate test setup.
The result provides a quantitative measurement of building airtightness. When additional investigation is necessary, diagnostics can help identify significant leakage paths rather than providing the project team with only a pass/fail result.
Whole-Building Air Leakage Testing in Cobb County
Whole-building testing evaluates the exterior enclosure as a connected system. Calibrated fans pressurize or depressurize the building while measuring the airflow required to maintain the specified pressure difference.
Air leakage can be distributed across hundreds of relatively small openings rather than concentrated in one obvious defect. Window perimeters, exterior doors, roof-to-wall transitions, loading areas, mechanical penetrations, and changes between wall systems can collectively have a significant effect on overall building airtightness.
QED LAB provides whole-building air leakage testing in Marietta and Cobb County to help contractors, consultants, architects, developers, and building owners evaluate completed enclosure performance.
Window, Storefront, and Curtain Wall Testing in Marietta
Windows and glazed exterior systems are important components of many commercial buildings around Downtown Marietta, Cobb Parkway, East Cobb, and the I-75 corridor. Their field performance depends on the manufactured assembly as well as perimeter seals, flashing, gaskets, joints, rough openings, and connections to surrounding wall construction.
QED LAB provides window testing in Marietta, GA, along with storefront and curtain wall testing for commercial projects. Field testing can help identify air or water leakage associated with installation and integration rather than relying exclusively on laboratory ratings for individual products.
Testing representative installations during construction can be particularly useful. If a recurring window, storefront, or curtain wall detail is allowing leakage, identifying it early gives the construction team an opportunity to adjust the installation before the same condition is repeated across additional areas of the building.
AAMA Field Testing in Marietta
QED LAB can support projects requiring AAMA 501.2, AAMA 502, and AAMA 503 field testing in Marietta when these procedures are specified.
AAMA 501.2 hose nozzle testing can help evaluate localized joints and seals in installed curtain wall and storefront systems. Water is directed at specific exterior joints while the interior is monitored for penetration, allowing individual problem areas to be isolated.
AAMA 502 may be used for field evaluation of installed windows and doors, while AAMA 503 can apply to installed storefronts, curtain walls, and related fenestration assemblies. These procedures help evaluate how systems perform after installation, where flashing, perimeter seals, adjacent materials, and workmanship can influence results.
ASTM E1105 Water Penetration Testing in Marietta
Water penetration testing can help determine whether installed exterior assemblies resist water under specified field conditions.
QED LAB provides ASTM E1105 water penetration testing in Marietta, Georgia, for installed windows, curtain walls, doors, and related fenestration systems. Water is applied to the exterior of the test area while a controlled pressure difference is established across the assembly. The interior side is then monitored for evidence of water penetration.
Depending on project requirements, QED LAB can also support ASTM E331 water penetration testing. The appropriate procedure depends on the exterior assembly, specifications, and purpose of the evaluation.
These tests can be incorporated into construction quality assurance or used as part of an investigation into an existing water-leakage concern.
Water Intrusion Diagnostics in Marietta and Cobb County
A water stain inside a building doesn’t necessarily identify where water entered the enclosure. Moisture can travel along flashing, framing, exterior sheathing, or other concealed components before becoming visible somewhere else.
QED LAB provides water intrusion testing in Marietta and Cobb County to help isolate potential sources under controlled conditions. Investigations may focus on windows, exterior doors, curtain walls, storefronts, sealant joints, flashing conditions, wall penetrations, roof-to-wall transitions, or interfaces between different exterior materials.
Controlled testing provides a systematic way to investigate suspected areas without waiting for a particular combination of wind and rain to reproduce the leak naturally.
Commercial Building Testing Along I-75 and Cobb Parkway
Marietta’s location within the Northwest Atlanta metro creates a diverse commercial market along major corridors such as I-75, Cobb Parkway, Roswell Road, and areas surrounding Downtown Marietta. Office properties, healthcare facilities, hotels, retail centers, multifamily developments, warehouses, and institutional buildings can each have different enclosure-testing requirements.
QED LAB can develop testing scopes around these different building types rather than applying the same testing plan to every property. A large warehouse may require a substantial whole-building air leakage setup, while a commercial office or hotel may place greater emphasis on repeated window installations, curtain wall systems, or water penetration testing.
Healthcare, Institutional, and Multifamily Building Envelope Testing
Marietta and the surrounding Cobb County market contain a significant number of healthcare, educational, government, multifamily, and other institutional properties. These buildings can contain complex exterior assemblies where uncontrolled air movement or moisture intrusion can interfere with intended building performance.
Multifamily properties introduce another concern: repetition. Windows, exterior doors, penetrations, balconies, and wall transitions may be installed many times throughout a single project. Testing representative assemblies can help identify recurring issues before they affect additional areas.
QED LAB provides building envelope testing for Marietta healthcare, institutional, and multifamily projects, including air leakage testing, fenestration testing, water penetration testing, and other field verification services based on project requirements.
Infrared Thermography and Enclosure Diagnostics
Infrared thermography can supplement other testing methods by identifying temperature patterns across building surfaces. Under appropriate environmental conditions, those patterns may indicate areas associated with air leakage, insulation irregularities, thermal bridging, or moisture-related conditions.
QED LAB can incorporate infrared thermography into Marietta building-envelope investigations when appropriate. Thermal findings are evaluated alongside construction details, environmental conditions, visual observations, and other testing data rather than being treated as independent proof of a specific enclosure defect.
Building Enclosure Commissioning in Marietta
Building enclosure commissioning helps project teams evaluate whether exterior systems meet established performance requirements throughout design and construction. Field testing can be scheduled at strategic stages so problems are identified while corrective work remains practical.
QED LAB supports building enclosure commissioning in Marietta, GA, through independent testing and performance verification. Depending on project requirements, testing may include air barriers, windows, curtain walls, storefronts, water penetration, or whole-building airtightness.
Early coordination is particularly useful when a project contains repeated exterior details. Evaluating representative assemblies before widespread installation can help reduce the risk of repeating the same deficiency across the building.
