Installing panels

● The first course (row of panels) should be placed in the starter trim

and securely locked along the entire length of the siding panel. Make

sure the panel is securely locked before fastening.

● Fasten the panels in the center of the nailing slots. Allowance should

be made for expansion and contraction by leaving a 1/4” gap between

the siding and all corner posts and channels (increase to 3/8” when

installing in temperatures below 40° F. If the panels are 20 feet or

longer, increase the gap to 3/8”.

● Do not drive the head of the fastener tightly against the nail slot.

Leave 1/32” between the fastener head and the vinyl (about the

thickness of a dime).

● Do not force the panels up or down when fastening. Panel locks

should be fully engaged; however, the panels should not be under

vertical tension or compression when they are fastened.

● Since vinyl siding moves as the temperature changes, make certain

that the vinyl panels can move freely in a side-to-side direction once

fastened.

● Check every fifth or sixth course for horizontal alignment. Also check

siding alignment with adjoining walls.

● When panels overlap, make sure they overlap by one half the length of the

notch at the end of the panel, or approximately 1”.

● Stagger the siding end laps so that no two courses (rows of panels) are aligned

vertically, unless separated by at least three courses (rows of panels).

● Always overlap joints away from entrances and away from the point of greatest

traffic. This will improve the overall appearance of the installation.

Fitting siding around ﬁxtures

Use a commercially available trim ring to fit siding to a penetration such as a faucet

or railing attachment, following the manufacturer’s installation instructions. If a com

mercial trim ring is not available for the application, refer to the figure below, which

illustrates how to fit the siding to the penetration. In addition, the following tips are

suggested:

● If hand-fitting to the fixture, always begin a new course of siding at the fixture

to avoid excess lap joints.

● Cut an opening 1/4” bigger than the fixture or the trim ring.

● When cutting, match the shape and contour of the obstruction.

Horizontal siding installation Installing panels ● The first course (row of panels) should be placed in the starter trim and securely locked along the entire length of the siding panel. Make sure the panel is securely locked before fastening. ● Fasten the panels in the center of the nailing slots. Allowance should be made for expansion and contraction by leaving a 1/4” gap between the siding and all corner posts and channels (increase to 3/8” when installing in temperatures below 40° F.

1/4" Horizontal siding installation 1/4" Fitting under windows To mark the section to be cut, perform the following: ● Hold the panel under the window and mark the width of the window opening on the panel. Add approximately 1/4” to both sides to allow for expansion and contraction of the siding. These marks represent the vertical cuts. ● Lock a small piece of scrap siding into the lower panel next to the window. This will be used as a template for the horizontal cuts. Mark it 1/4” below the sill height.

Horizontal siding installation Under eave installation ● Nail undersill trim along the top of the wall, flush with the eave of the house. Furring may be necessary to maintain the proper pitch of the topmost siding panel. Should more than one length of undersill trim be required, make a splice as shown by cutting away 1” from the back of the undersill trim and lapping the sections, leaving a 1/4” space between nailing strip sections.

Horizontal siding installation Finishing a gable end To install around gable ends, make a pattern that duplicates the slope of the gable: ● Lock a short piece of siding into the gable starter course (i.e., the last course before the gable starts). ● Hold a second piece of siding against the J-channel at the slope of the gable. Mark the slope with a pencil on the short piece of siding. Check the angle template every few courses.
