Vision proof louvers are great for allowing air ventilation while preventing visual contact between rooms.

This Vision-Proof Fire Rated Louver is comprised of an inverted "Y" design with concealed INTUMET™ fire seal. It is designed to achieve fire ratings in metal doors up to 90 minutes (to acheive a 4 hours rating, a Fire Block Insert can be added for additional fee, see option tab for details). The intumescent material expands at 550ºF and is suitable for hot or cold weather. The louver free area is 48% of order size (52% obstructions).

It is constructed from 20 gauge cold rolled steel, thus lending a smooth finish that is durable and built to last. It can be mounted on doors with a thickness of 1-3/8" or  1-3/4" (select from options above) or as an application on walls. The front frame is attached to the lower core with concealed screws which provides a very clean look.

This product can be ordered with a standard or galvanized steel (add 20%). Galvanized steel is recommended for exterior or high humidity applications.

FB Intumescent Block can be used to achieve fire ratings for door louvers in metal doors of 1.750" (44mm) or greater thickness. The 0.55"(14mm) thick FB Intumescent Block is designed to layer inside a two-part metal louver set attached to both sides of the door. A reinforcing inverted channel is required at the bottom of the cut-out to support the FB Intumescent Block. There is no limit on door thickness; additional lateral support is needed for louvers in doors with greater thickness.

The FB Intumescent Block has been assessed up to four-hour fire rating by UK Warrington Fire Research Centre as part of the Fire Block Louver System (FBLS) for fire-rated steel doors with apertures up to 18" x 60" (0.46 x 1.5m).
