The AMCA Water Penetration Test provides a method for comparing various louver models and designs as to their efficency in resisting the penetration of rainfall under specific laboratory test conditions.The beginning point of water penetration is defined as that velocity where the water penetration curve projects through 0.01oz of water penetration per sq. ft. of louver free area.

These performance ratings do not guarantee a louver to be weather-proof or stormproof and should be used in combination with other factors including good engineering judgement in selecting louvers.

Large opening sizes may ship in multiple ship sections, which require field assembly to make-up the overall louver size. Design, materials and installation of structural reinforcement, required to adequately support large opening, is not provided by KBE. Unless specifically indicated, the following are Notincluded in the quote provided:* Installation hardware (anchors, angle clips,continuous angles, shims, fasteners, inserts, backer rod and sealant).* Structural calculations by a professional engineer.* Field measuring and/or installation.* Miscellaneous flashing trim or enclosures.* Blankoff panels.* Mullion covers or mullion hardware.* Hinged louvers and/or removable type (louversinstalled within a removable subframe).* Custom or special bird/insect screen* Paint finishes.

When used in Direct fan disharge application louver should be located at least 3m from fan discharge.
