CertainTeed Vinyl Siding Installation Guide
Porch Ceilings
The procedures used to install a porch ceiling are in many ways similar to those used to install soffit. These procedures vary slightly, depending on whether you’re working on new construction or a remodeling project.
New construction projects
Begin by installing receiving channels on all four sides of the porch.
If you are using
If you plan to use light blocks to attach external light fixtures, install them to adequate backing.
Plan the layout of the ceiling panels to achieve an even balance or to align with adjacent work. If the ceiling panels will run parallel to the ceiling joists, you will have to install additional 1" x 3" wood furring nailing strips. Install these nailing strips perpendicular to the ceiling joists, nailing according to the schedule below.
Invert
Install the first panel into the channels at one end of the porch. Be sure to leave room for expansion. Nail according to the schedule below, positioning the nails in the centers of slots.
Do not nail tightly. Install remaining panels. When cutting the last panel of the first course, be sure to allow room for expansion.
Nailing schedule for soffit
For areas where more than one panel length is needed, use a double channel lineal.
If necessary, rip cut the final panel and use a snap lock punch to create tabs every 8" to 10" along the cut edge. Attach utility trim and insert the panel into the receiving channel.
NOTE: For best results, ensure you have adequate ventilation.
