Adirondack starter installation
In order for Adirondack vinyl log siding to be properly installed in a level
fashion, the starter at the bottom of the wall must be level.
● Determine the lowest point of the wall that will be sided; from that point,
measure up 1/4” less than the width of the starter and partially drive a
nail at one corner.
● Attach a chalkline; go to the next corner and pull the line taut.
● Make sure the line is level by using a line level or a 4’ level.
● Snap the chalkline and repeat the procedure around the entire house.
Using the chalkline as a guide, install the top edge of the starter along the
bottom of the chalkline, nailing at 10” intervals. Allow space for the corner
posts, J-channels, etc.
● Keep the ends of starter strips at least 1/4” apart to allow for expansion.
● Leave approximately 1/4” between the starter and the corner post.
● Nail in the center of the starter strip nailing slots.
Adirondack J-channels
● Install 1 1/4” J-channels along windows and wall not requiring
corner posts.
Follow J-channels installation instructions in the Vinyl Siding
Estimating and Installation Guide.
Adirondack outside corner posts
The installation of the Adirondack outside corner posts is important as
these corners are an integral part of the wall system.
● A water resistant material should used to flash the inside and outside
corners a minimum of 10” on each side.
● Place the corner post in position, allowing a 1/4” gap between the top
of the post and the eave or soffit.
● Position a nail at the top of the upper slot on both sides of the corner
post, leaving a 1/32” gap between the nail heads and the corner posts.
The corner post hangs from these nails.
● The balance of the nailing should be in the center of the slot, 8” to 12”
apart, again leaving 1/32” between the nail head and the corner post.
This allows for the expansion and contraction to occur at the bottom.
● The corner post should extend 3/4” below the starter strip. Make sure
the posts are plumb (i.e., vertically straight).
● For a better finished appearance, remove a 3/4” portion of the nail
hem on both sides of the corner post.
Adirondack inside corner application
Two J-channels must be used when installing Adirondack vinyl log siding in
the inside corner of a house.
You
must follow the same instructions as for the installation of the outside
corner post while using two J-channels installes as shown in the illustration.
