Install panel

If necessary to maintain the slope angle, install furring under the sill as described on pages 31 to 32.

NOTE: You can eliminate this step by using dual undersill trim. This trim has two receiving channels. Use the inner channel if you’ve cut the siding panel near the locking edge. Use the outer channel if the cut has been made near the butt edge.

Use a snap lock punch to raise tab faces on the outside of the panel. Punch out a tab every 6".

Push the horizontal edge of the cut into utility trim. Slide vertical edges of cut into J-channels at window sides. Make certain the installed panel locks into the panel below.

Fitting over windows and doors

The procedure for cutting panels for installation over windows and doors is similar to that explained earlier.

If necessary to maintain the slope angle, install furring above the window or door as explained on pages 31 to 32.

Drop the panel into position, making certain it fits into the undersill trim and J-channel at the top and J-channel at the sides. Interlock the panel with the siding panels below.

Fitting at narrow openings between windows

To simplify installation in areas such as that shown in the illustration, install J-channel on both sides of opening.

Bow the panel toward you and slip it into the channel.

If the area is very narrow, leave one J-channel unnailed except at the lowest point (as shown). Bend this channel out slightly to insert panel. When the panel is in place and nailed, nail the J-channel immediately above the panel and repeat the procedure. Be sure to leave adequate tolerances for expansion and contraction.
