WINDOW AND DOOR J-CHANNEL

J-channels are designed to receive the siding panels and must be

installed around all windows, doors, other large openings, and in the

gables where built-in J-channels are not present. J-channels can be

installed over old wood casing or placed next to the casing leaving the

old window casing exposed.

• Water runoff can also be accomplished by making a series of

notches and tabs in the J-channel (FIG 10.1).

• Install J-channel in this order: bottom, sides, then top.

• Miter J-channels at corners to prevent gaps and allow for proper

water drainage (FIG 10.2).

WINDOW AND DOOR TRIM OPTIONS

As an alternative to J-channel and standard corner post, cellular PVC

trim can be used to give a bolder nish to the trim areas.

ADDITIONAL TIPS

To aid in short panel siding installation, it may be helpful to leave

J-channels or corner posts loose around openings. In some cases, you

may need to leave J-channels off to get short pieces in and then slip a

J-channel in after installation. If leaving J-channels loose, bow out ends

and slip into J-channels then lock together. To secure the J-channel, nail

through the backside of the J-channel at every other row into the casing

that it is butted up against. A nail punch will help in this procedure to

set your nails into the wood.

NOTE: Install ashing per window manufacturer instructions.
