A few months ago, Recon Independent Assessments provided field quality control testing on a project that was installing both curtain wall and storefront systems.
During the first round of testing, quite a few failures were observed using the ASTM E 1105, the field testing specification called for in the project specifications.
After the installer evaluated the cause of the failures, they conducted remedial work to ensure the installation was watertight. Re-testing was called for and Recon returned to test the installed systems once again.
Unfortunately, water penetration continued in both systems.
Nearly six months passed without word from the project regarding additional re-testing being scheduled to confirm a second round of remedial work had solved the leaking.
The installer contacted Recon asking questions regarding the test pressures that had been used during the previous field testing.
The project specifications called for a curtain wall that had evidenced water penetration resistance at 12 PSF during laboratory testing using an ASTM E 331. The project specifications called for the use of the ASTM E 1105 to evaluate the installation in the field. A knowledgeable professional would know that the ASTM E 1105 requires a test pressure in the field of 2/3 of the pressure used in the laboratory (8 PSF).
Despite documentation detailing the use of the ASTM E 1105 and references to the project specifications that determined the test pressures, the installer was questioning the testing rather than focusing on providing a solution to the failures.
Care in selecting a glazing contractor that understands a project's specifications and has the ability to demonstrate quality work can best prepare your project for success. Ask for proof of past testing success from the contractor that is bidding, price should not be the only determining factor in awarding a bid.
If you ignore testing or engage contractors that do not understand its importance and you may be seeing this:
 |
| In an effort to resolve leaks, an unknown "sealant" was applied within the storefront system. |
 |
| Despite the addition of the "sealant", leaks continue to plague the project. |
