GENERAL INFORMATION Gentek vinyl products, horizontal and vertical siding and soffit, are easy to apply when the job is planned and the simple directions in this manual are followed. Step-by-step instructions should be followed in the proper sequence to avoid problems. Vinyl expands and contracts with changes in temperature. The amount is approximately 1/3" (8 mm) in a 10' (3 m) length for a temperature change of 131°F (55°C).
GENERAL INFORMATION BASIC RULES CAULKING Following these basic rules will ensure proper installation, with sufficient allowance for expansion and contraction during changes in temperature. Caulking is necessary in areas where water penetration is possible (pipes or wires through walls, or J-channels on sides of windows or doors). Use only good quality caulking – with a sustained flexibility, good extensibility and long life. DO NOT USE OIL BASE CAULKING. 1.

SIDING INSTALLATION STEP 1 INSIDE CORNER POST HORIZONTAL SIDINGS The first step, whether you are re-siding or applying on new construction, is to determine where you will apply the first course of siding. This can be at the same level as the old siding, or on new construction, at a level that will cover the edge of the foundation. Use a chalk line and a level to obtain a horizontal starting point so that all installed siding will be perfectly level.
SIDING INSTALLATION STEP 4 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. Install the undersill trim, extending it past either side of the window, as far as the outer edge of the J-channel face.
SIDING INSTALLATION DRIP CAP The drip cap is nailed above the window and door and extended on either side, flush with the exposed leg of the J-channel. A tab is cut at either end of the drip cap and bent down over the J-channels. If required to maintain panel angle, a furring strip is nailed over the drip cap. Tab of drip cap bent down inside the J-channel. The undersill trim, installed in a reversed position, must be extended on both sides, flush with the outer edge of the J-channel.
SIDING INSTALLATION STEP 6 b. Using the snap lock punch, punch ears in the trimmed edge of the siding panel at 8" (200 mm) intervals. Be sure that the “ears” face outwards from the wall. TOP-OF WALL FINISH Ears punched in panel. c. Lock the top edge of a siding panel in the undersill trim and secure the lock at the lower edge of the panel. The snap lock punch must be used whenever the trimmed edge of a panel is to be engaged in the undersill trim.
VERTICAL SIDING INSTALLATION INSTALLING VERTICAL SIDING ON MAIN WALLS Refer to pages 4 - 6 for the accessories to be used for vertical siding installation, and for the method in which these are cut for overlapping. STEP 1 VERTICAL J-CHANNEL Vertical J-channel serves as starter strip for vertical siding. Use a chalk line and level to ensure the J-channel is straight and level. Install J-channel along chalk line as a receiver for the vinyl siding.
VERTICAL SIDING INSTALLATION NOTES At the peak of the gable, drop a chalk line perpendicular to the starter strip. To determine where to start the first panel – measure from chalk line along the starter strip in units of 5" (127 mm) until you get to a point where the measurement to the J-channel is less than 5" (127 mm). Mark that point with a pencil. Measure back toward the center of the gable from that point 1-1/4" (32 mm), and draw a vertical line, parallel to the line dropped from the gable peak.
