4. Installing the Wallboard
Wallboard should be attached to the inside and outside of the steel frame, using Grip-Rite 25-lb #6 x 1-5/8” Bugle-
Head Black Phosphate Phillips drywall screws. Cut-outs are needed on the interior wall to accommodate the duplex
outlet, and on the exterior wall to accommodate the Control Panel.
Terra furnishes U-Channel brackets that provide a mounting support for locations where a wallboard panel does not
extend all the way to an upright support member. These brackets screw to the nearest upright, approximately midway
between the bottom and top of the panel.
Note:
Before installing the wallboard over the window support frame, mark it to indicate the window cutout location:
the distance between the two support bars and the two vertical bars they attach to (approx. 46-5/8”W x 36”H).
Note:
For seismic anchoring, drill through the cleanroom frame to anchor it to the floor in accordance with local
seismic code.
5. Installing Air Exhaust Vents
Create cut-outs in locations indicated above for two air exhaust vents in the Anteroom and one in the Buffer Room
(see Figure 5). Each cut-out should be large enough to hold the vent snugly in place, and to allow the polypropylene
weld bead to seat inside the wall, so that the flange fits flush against the drywall.
Position each so that the bottom of the vent is at least 4” above the floor, to allow space for FRP lamination and floor
coving (if desired). The portion of each vent that includes the adjustable baffle plate goes on the outside of the room.
