Installing the Adirondack vinyl log siding
As with all vinyl siding installation, the first row of siding is the one that will
guide the rest of the wall. Start the installation the right way to have an easy
installation.
● Place the first vinyl siding panel into the starter trim and slide the panel into
the pocket of the corner post.
● Fasten the panels in the center of the nailing slots. Allowance should be
made for expansion and contraction by leaving a 1/4” gap between the
siding and all corner posts and channels (increase to 3/8” when installing in
temperatures below 40° F.
● Do not drive the head of the fastener tightly against the nail slot. Leave 1/32”
between the fastener head and the vinyl (about the thickness of a dime).
● Do not force the panels up or down when fastening. Panel locks should be
fully engaged; however, the panels should not be under vertical tension or
compression when they are fastened.
● Since vinyl siding moves as the temperature changes, make certain that the
vinyl panels can move freely in a side-to-side direction once fastened.
● Check every fifth or sixth course for horizontal alignment. Also check siding
alignment with adjoining walls.
● When panels overlap, make sure they overlap by one half the length of the
notch at the end of the panel, or approximately 1”. The foam insert in the
back of the panels should but together.
Always overlap joints away from entrances and away from the point of greatest
traffic. This will improve the overall appearance of the installation.
Vinyl siding panel seams should be staggered along the installation and should
be at least three courses apart.
Installing under window and crown area.
Several options are available to secure the topmost panel below the eaves
or windows. Depending on where the siding panel has to be cut, you have to
follow one of the methods below:
If the Adirondack panel is cut in a thick section of the panel;
● Cut the siding panel and punch snap locks every 6” to 8”.
● Push the panel securely into the top J-channel.
If the Adirondack panel is cut above or below the thickest section of the panel;
● Place a smaller 5/8” J-channel inside the 1 1/4” J-channel to act as an
undersill trim.
● Cut the siding panel to the appropriate dimension and punch snap locks
every 6” to 8”.
● Push the panel securely into the 5/8” J-channel.
If the Adirondack panel is cut above the foam section of the panel;
● Install an undersill trim in the top J-Channel.
● Cut the siding panel to the right dimension and punch snap locks every
6” to 8”.
● Snap lock the siding panel into the J-channel, checking for proper
free movement.
At all time the top of the panel going into the undersill trim or 5/8” J-channel
must have a series of snap locks on the top.
