Air Infiltration, Water Resistance and Uniform Load Testing-

Fenestration products serve as openings in the building envelope. It is imperative that windows and doors are weather tight and structurally sound. This test method is used to determine the rate of air leakage, water resistance, structural performance, forced entry resistance, among other tests. The test results facilitate manufacturer, consultants and code officials the ability to ensure that the product will meet building design and building codes.
 
Air filtration is determined by a high precision mass flow meter while the specimen is subjected to a constant air pressure differential. For water resistance tests, specimens are checked for water penetration under cyclic and static air pressure, which simulates differing storm conditions. Fenestration Testing Laboratory test apparatus ensures that all test samples receive the necessary water application at the required test pressure conditions.

Test results determine if water penetration occurs inside the product or wall cavity. For the uniform load tests, the specimen’s structural integrity is evaluated while prescribed static high pressure differential is created across the specimen, simulating both positive and negative wind loads. Fenestration Testing Laboratory uses precise digital instrumentation to measure permanent set and deflection readings under ratios established by the standard.
