Onsite Chamber testing can be performed to determine air leakage and water penetration. Air infiltration shall be identified so that it can be controlled or eliminated. High excessive leakage can result in condensation inside buildings leading to high costs for repair and maintenance. Test should be conducted early on in the installation phase so that any problems can be corrected before too much of the work is completed. Water testing helps to account for quality assurance; if leakage occurs in the specimen there would be additional work with repair or rectification being required. Failure to do the testing potentially may have a big impact in the future. Testing will help to identify weaknesses enabling improvements to be made for the weather tightness performance of the curtain wall, windows and doors.
