2 WMC&T Testing Services WMC&T follows AAMA - ASTM Testing methods as established standards used to test the capability of windows, curtain wall windows, storefront windows, sliding glass doors, skylights, etc. to resist water/air intrusion over a specified time period. Our teams are well trained and follow AAMA and ASTM standards to the letter. The information gained from our tests procedures are used by the manufacturer, design team and construction team to identify and correct product issues, application issues and/or installation process issues that could potentially be applied across an entire building or buildings. WMC&T does not believe that our job ends with PASS/FAIL results of a given test procedure. WMC&T believes that our testing responsibility to the design and construction teams is to ensure that whatever issues arise during the test process that they are clearly identified to all participants of the design and construction teams and that recommendations for the issues are provided. Our testing responsibilities include communicating with the Installation contactor and window/door manufacturers to ensure they have a knowledgeable representative to attend the tests process and to provide feedback to the installation contractor and manufacturer(s) on quality trends or issues found during our testing of their manufacturing or installation procedures. Our resultant testing report will identify: the specific assembly and wall system at assembly and the testing process used adherence to design and effectiveness of installed waterproofing details adherence to the manufacturer s installation instructions adherence to the project plans and details at the tested assembly proper or improper installation issues of the sliding glass door, window assemblies, curtain wall windows, storefront windows, skylights, etc. point(s) of failure (if any) extent of water intrusion isolated or widespread photographic exhibits that will illustrates the issues found during the testing procedure recommendations for mitigation of deficiencies identified during testing procedures. WMC&T has extensive construction experience that allows us to provide the Design/Construction Team with real world approaches to correcting deficiencies identified during testing. 2

TYPES OF TESTING: Chamber or Differential Pressure Testing: A pressure chamber constructed on the interior or exterior of the envelope of a building at a specific location where a fenestration assembly meets the envelope to test moisture driven through fenestration assembly components and/or fenestration/wall assembly components. The assembly or component is subjected to negative or positive forces while simultaneously a spray rack test is directed at the assembly to draw or push the moisture into the fenestration/wall assembly to simulate a negative or positive pressure under a wind-driven rain condition. Chamber Testing - Positive Test Chamber A chamber built of wood frame construction and a 6 mil clear plastic that is attached to the outside wall assembly of a window or door system. This chamber is built as air and water tight as possible. Care is taken to minimize damage to the finished building system. The same spray grid system that was described for the spray test is installed inside the test chamber instead of attaching it to the frame assembly. A blower with a speed control and a relief valve system is used to pressurize the chamber with a static air pressure. The air pressure in the chamber is determined by the greater of either the architectural specifications, the design pressure of the test specimen, or the maximum positive design pressure of the building in which the specimen is installed. Chamber Testing - Negative Test Chamber A chamber built of wood frame construction and a 10 mil clear vinyl. It is attached to the inside wall assembly of a window or door system. This chamber is built as air tight as possible. It is also designed where it can be removed in a few seconds to enable quick access for troubleshooting. The same spray grid system that was described for the spray test is attached to the frame assembly. It is stood up against the wall system on the outside of window or SGD that is being tested. A vacuum with a speed control is used to create a negative pressure inside the test chamber. The differential negative air pressure in the chamber is determined by the greater of either the architectural specifications, the 3

4 design pressure of the test specimen, or the maximum positive design pressure of the building in which the specimen is installed.

6 Spray Testing AAMA Quality Assurance and Diagnostic Water Leakage Field check of Installed Storefronts, Curtain Walls, and Sloped Glazing Systems AAMA 501 Kinetic Energy Spray Test - This test method also simulates a 44 mph wind-driven rain event in small, segmented areas using a standard ¾ inch diameter hose in which a calibrated nozzle is attached with a calibrated pressure gauge. The spray is directed at a specific joint, crack, or defect to reveal potential water leakage and assist in identifying the point of entry and path of travel of suspect moisture intrusion. AAMA Spray Nozzle Test Water Spray Rack - Test simulates a Spray Rack Water Leak Investigation wind-driven rain condition on a specific assembly and/or component. It can be useful in determining a specific cause and origin of moisture infiltration when it is used to test individual components of an exterior envelope area or assembly. Specific assemblies and/or interfaces of assemblies are isolated and subjected to controlled amounts of moisture instead of spraying water over a large area in an uncontrolled manner that will not reveal specific components or conditions that are the cause of water infiltration. 6

9 ROOFING SYSTEM VECTOR MAPPING WMC&T provides Electric Field Vector Mapping leak detection on waterproofing membrane for testing of capillary defects and/or breaches in the membrane. Field Vector mapping is the process of identifying the source of potential water leakage on roofing technologies that incorporate dielectric membrane overlays. Low-Voltage Electric Field Vector Mapping a) Testing of entire roof on an area-by-area basis b) Wetting of the entire membrane test area with water prior to the start of each test and maintain wet condition for the duration of testing. Aids in verifying integrity of the membrane at drains and penetrations by localized testing. High-Voltage Leak Detection Testing a) Tests perimeter of entire roof and any other areas not able to be tested using low-voltage method CERTIFIED IR IMAGING OF BUILDINGS AND ROOF ASSEMBLIES Thermal Imaging Thermograph technology utilizes an infrared camera to produce a heat diagram or a visible picture using infrared wavelengths. This imaging technique is a quick, powerful and non-invasive method for detecting and assisting in the diagnosis of areas exhibiting energy loss, suspect moisture behind wall assemblies, and possible moisture in construction materials. 9
