Hinges are also factory-welded to screen doors,
which swing to the outside of the building. The
method used in hanging screen doors is similar to
hanging entrance doors. A spring, however, is needed
to hold the screen door closed.
After the exterior members have been erected,
work can begin on installing the interior assemblies.
These include the liner panels, furring, hardboard
flashing, and the trim.
LINER PANELS. Installation of the liner panels
consists of installing furring strips, hardboard liner pan-
els, and trim and battens. Various liner panel parts were
shown earlier in view B of figure 9-2.
To install end walls properly, precut the liner
panels according to the cutting diagrams. The hard-
board must be installed with the smooth surface
exposed and with a 1/8-inch gap between panels to
allow for expansion (fig. 9-9). A scrap piece of hard-
board or batten can be used as a shim or spacer to
maintain the proper gap.
BASE FURRING. Nail the base furring to the
floor 3 inches from each end and 2 feet 8 inches OC,
with the inside edge 7 3/8 inches from the building
structural line. You can get a better of this by referring
to figure 9-10. When base furring is to be used on a
wood floor, use 8d box nails. Use 1 1/4-inch No. 9
concrete nails for a concrete floor. Drill the 2 by 2s
and girts with a 5/32-inch bit so furring can be attached
to the sidewall and cave girt with 2-inch panhead No.
10 sheet-metal screws. Attach the hardboard to the
furring strips with 1 1/4-inch aluminum shingle nails
on 4-inch centers at the sides and ends (see fig. 9-11).
Use 8-inch centers at the intermediate furring.
