Bell & Spina self-performs fixed glass water penetration testing consistent with the methodologies advocated by the American Architectural Manufacturer’s Association (AMMA) standard, “Quality Assurance and Diagnostic Water Leakage Field Check of Installed Storefronts, Curtain Walls and Sloped Glazing Systems (AMMA 501.2).”  We supplement our efforts with the added services of our established commissioning partners, particularly with regard to operable glass water penetration testing (AMMA 502).

This field check procedure is intended to evaluate those joints, gaskets and sealant details in the glazing which are designed to remain permanently closed and water tight.
