This guide illustrates test procedures to ensure air and moisture penetration is minimized in new window installations.
In addition, the AAMA guide provides verbiage that can be directly inserted into project specifications, saving time and effort. The only problem with the verbiage provided is that it is often inserted aamw a generic format that does not provide details as to the areas, quantity, and specific testing pressures.
It is up to the contractor to ensure these testing parameters aamx established. Once testing parameters are specified, the testing agency ensures that proper procedures were followed during the construction installation process.
Typically, a sampling of windows from the project is selected and tested. The construction contract will appoint a party responsible for the cost of the testing.
AAMA Test Standard for Air & Water Infiltration
The number of tests depends on the size and budget of the project. The project architect, manager, or owner specifies the amount and locations of the windows to be tested; this happens either early in the project or at three intervals in the case of large projects: With a large project, testing early on can prevent expensive repairs if a design flaw is identified during the first phase of testing.
Normally, if a window fails, the contractor should be prepared for a wider scope of testing. One-week notice prior to water testing is usually given to all construction crew members concerned with window installation. It is not recommended to notify anyone of the actual test locations until xama testing agency arrives onsite. Water penetration observed when testing windows will be given extra attention for the remainder of the project. Before testing, the window installation is visually observed.
Are the edges perfectly horizontal and vertical? Is the window square? What is the drainage design? How is the installation quality? Have flashing and sealing been properly finished? Then both air and water leakage in that order are determined using a test chamber of constant pressure.
AAMA Water Spray Testing
A predetermined amount of air leakage is allowable; however, no water leakage is permitted at all. A specified pressure is maintained while any escaping air is measured. Water leakage uses the same method while spraying the window from outside to observe indoor penetration. Any moisture not coming in through the window, but getting in somehow, will be subject to further forensic investigation.
Guidelines for the type of equipment to use and test procedures to follow are specified in the AAMA If the window installation was completed within 6 months, and there is not a building occupancy permit COthen the AAMA is the right document to use. BDG utilizes professional testing equipment that is calibrated to each specific testing standard for accurate results.
Our field consultants are properly trained and knowledgeable of all testing standards. BDG has extensive knowledge of most building systems and specializes in forensic water intrusion investigations.
This allows us to not only properly test fenestrations on new construction projects, but also pinpoint the cause of any test failures and provide accurate recommendations to achieve successful testing results.
