Facade Water Hose Test
The aesthetic and overall performance of the façade will be observed during harsh weather conditions. AAMA 501.2 Standards and CWCT TN 41 (Centre for Window and Cladding Technology) Façade Water Hose Testing is the most efficient method to ensure that your cladding is suitable for its intended purpose and capable of achieving a high-quality building envelope.

AAMA 501.2 is a standard that outlines the procedure for conducting the hose nozzle water spray testing.

CWCT TN 41 is a technical note published by the Centre for Window and Cladding Technology that provides guidance on on-site testing for water-tightness.
However, evaluating the water tightness of a facade is just one component of these standards. It provides confirmation that both glazing and cladding will meet the criteria for your facade. When combined with effective design and installation, water hose testing offers reassurance that your building will deliver the expected performance, granting you peace of mind.
The facade water leakage testing is a specific method used to assess the water tightness and workmanship of doors, windows, and wide glass surfaces designed to remain permanently closed, such as storefronts, curtain walls, and sloped glazing systems.
The test is conducted using a hose fitted with a nozzle that sprays water at a set pressure and flow rate over a length of joint for a specific time.
Façade water hose test standards AAMA 501.2-15 or CWCT TN 41, should be conducted at regular intervals during construction to ensure the quality of the results. In most cases, these standards serve as a criterion for accepting the curtain wall upon project completion
