SUGGESTED LOUVER INSTALLATION METHODS (PER AMCA)
Louvers are generally installed in one of the following manners and fastened by the methods shown:
11.1: MASONRY
11.1.1: Strap Anchors—Straps must be installed while masonry is being poured or while blocks are being laid. (See Figure #18)
11.1.2: Expansion Anchors—Lead shields and bolts or expansion anchors made for masonry may be used. Fastening can be achieved through the louver frame or by using angles located behind the louver. (See Figures #19 & #20)
11.2: METAL SUBFRAME
11.2.1: A flanged frame louver installed with fasteners into the subframe is commonly used. (See Figure #21)
11.2.2: Fasteners through the louver frame into the subframe can be used if blade spacing and accessibility permit. (See Figure #22)
11.2.3: Clips, continuous angles, or plates may be installed behind the louver and fastened to the subframe. (See Figure #23)
11.3: STRUCTURAL STEEL
11.3.1: Installation is similar to subframes as described in 11.2. Welding may be considered in certain applications.
11.4: WOOD FRAMES
11.4.1: Same installation as metal framing except that wood screws would normally be used.
11.5: FREE STANDING COLUMNS
11.5.1: Large clip angles may be bolted or welded to columns. Horizontal support members of the louver rest on the clip angles, and are bolted or welded in place. (See Figure #24)
