TRIM DOORS, WINDOWS AND OTHER OPENINGS

J-CHANNEL

J-channels are used as trim on the

sides of windows and doors and

as ﬁnishing trim on gable ends.

Place J-channels on the sides

of the window and door frames,

extending trim 1" (25 mm) past

top and bottom edge of the frame.

Face will be trimmed back for good

visual appeal.

(if required).

New siding

Sill trim

J-channel

Caulking

Install the undersill trim, extending it past either side of the window, as

far as the outer edge of the J-channel face.

Undersill trim is also used in an inverted position over the tops of

windows and doors and where trims butt against window framing.

Caulk where J-channel and sill trims meet the opening frame.

UNDERSILL TRIM

This trim is used above and below openings, and at the top of walls

adjoining sofﬁts. Undersill trim can be furred out to preserve the proper

panel angle. Apply a furring strip to the wall, butting it to the underside

of the window sill.
