Installation Guide

ESTABLISHING A BASE

It is critical to carefully install the rst row of siding as it is the basis

for installing all remaining panels. Start by installing the starter strip or

J-channel (see page 7). Begin installing the rst panel of siding at the

lowest wall area. Snap the bottom panel lock into the bottom edge of

the starter strip along its full length. While applying upward pressure,

slide the end of the panel into the corner post. The siding locks onto

the steel starter strip. To prevent panel distortion, avoid forceful pulling

or jamming when nailing. When installing panels at inside and outside

corners, make sure that the siding panel butts align at the corners on

both walls.

NOTE: A 6" minimum clearance should be given between

ground and bottom of the rst row.

NAILS

For installation, nails must be long enough to penetrate the studs at

least 3/4" or, if stud is not available, the nail must extend past the back

of the wood sheathing at least 3/4". Drive the nail straight through the

center of the factory-slotted hole, making sure the nail is snug but not

tight (FIG 11.2). This allows the siding to expand and contract as well

as prevent any waving or buckling. Never slant nails up or down as this

may cause the siding to buckle. When a trim nail head will be visible,

color match it to the siding or accessory colors. Follow these same

techniques when using power nailers and make necessary pressure

adjustments.

NOTE: If there is a wave in the wall, use shims to straighten out

the wall. This will help to smooth out uneven surfaces.

NAIL SPACING

Nails must be attached in the middle of all nail slots for horizontal sid-

ing

(FIG 11.3). Nails should be placed approximately 16" on center, no

closer than 8" from the end of the panels. If you encounter uneven

spots on the wall, place the nails on each side of the spot and let the

panel hang over it, or use shims to level out the wall. This maintains a

level appearance.

NOTE: Prior to installation, replace all rotten or damaged wood to

ensure an even appearance.
