Soffit
If you are going to install soffit, you may want to install the receiving
channels for the soffit at this point. The illustrations show alterna-
tive approaches for installing siding and soffit receiving channels.
Options for transitions
If a wall requires more than one course of vertical siding or Board
& Batten or if you are transitioning to another cladding, you can
proceed in one of two ways:
• Option 1. Use two lengths of J-channel, back-to-back,
at the joint between the two courses (A).
• Option 2. Use a combination of one length of J-channel
and one length of drip cap (B).
Installing the siding panels
Plan the panel layout. Correctly installed vertical siding should
have a balanced appearance. This means that if you were to draw
a vertical line down the center point of a wall, you would have an
equal number of panels to the right and left.
If you have to trim panels to fit, the end-most panels should be
the same width. To do this, divide the space to be covered by the
width of one panel over both ends of the wall. For example, if a
wall required 25 full panels plus 10", you will need to rip cut two
5" lengths of panel to create partial panels for the end pieces.
Use 2" (minimum) corrosion-resistant nails to penetrate the wood
substrate at least 3/4". Do not drive nails at an angle.
Do not drive nails down tightly. Drive nails until there is 1/16"
between nail head and the nail flange.
Always position the top most nail at the top of the top most full
nail slot. Center the remaining nails in the slots. Space the nails
vertically 12" o.c.
