Preparation
Step 1
Install a solid, nailable sheathing
prior to applying vertical siding, if
needed, to level the surface or provide
sufficient material for proper fastener
penetration. Use minimum 7/16" ply-
wood, OSB or equivalent.
Step 2
Snap a level chalk line around the
base of the sidewalls. Typically, the
chalk line is positioned so that the
bottom of the J-Channel is 1/4"
below the lowest point on the wall
that will be sided. (See the “Installing
Accessories” section for tips on snap-
ping a chalk line.) Install a J-Channel
along the chalk line as a receiver for
the vertical siding.
Installation
Step 1
Install vinyl outside corner posts,
inside corner posts, and door/window
trim, and/or J-Channel as needed.
See previous sections for corner post
installation techniques.
Step 2
Install top and bottom J-Channel:
Apply J-Channel along the top and
bottom of the walls to receive the
siding panels (Fig. 1).
a. Install the bottom J-Channel.
Overlap J-Channels 3/4". To do
this, cut out a 1" section of the
nailing flange and face return
(Fig. 2).
b. Install inverted J-Channel along
the top of the wall, under the eave
and the gable. Overlap J-Channels
3/4" to allow for expansion.
NOTE: If you’re going to install
soffit, you may want to install the
receiving channels for the soffit
prior to this point.
