Parts of Vinyl Siding
Vinyl siding is a popular choice for home exteriors for new homes as well as home renovations. The vinyl siding parts are simple to connect, making the product popular with do-it-yourselfers. Different siding profiles and colors give homeowners a wide range of choices for customizing their house’s exterior. In most instances, the affordable price of vinyl siding parts enhances its appeal.
Vinyl Siding Profiles
Vinyl siding profiles replicate the look of traditional wood lap siding. Each piece of siding has the profile, or shape, stamped on it, so there’s no need to sort through stacks of boards looking for straight boards that don’t have knotholes in them. Common profiles are Dutch-lap, single lap, double lap and triple lap. Double and triple lap allow the placement of the equivalent of two or three traditional boards at one time, which saves on installation time. In addition to various vinyl siding profiles, each profile is available in smooth and textured surfaces. Vinyl siding profiles come in different gauges, or thicknesses, as well.
Vinyl Siding Posts
Vinyl siding posts serve as trim to give the vinyl siding a finished look. The posts also serve the function of holding the ends of the vinyl siding in position. Vinyl siding posts fit over the inside and outside corners. A flange with pre-drilled holes allows the installer to secure nails through them to attach the post to the house’s sheathing. Opposite the flange is a channel that holds the vinyl siding in place. The posts are the first items installed. As successive rows of vinyl siding go into position, the ends of each profile snap into the channel receptacle on the corner posts.
Vinyl Siding Starter Strip
In order for lap siding of any type to have a uniform appearance, the bottom row must have a narrow piece that attaches behind it to cause it to protrude like the rest of the lapped pieces. Vinyl lap siding operates on the same principle. A start strip positioned at the lowest edge of the first profile piece goes on the house as soon as the vertical corner pieces are secure. The starter strip must be level across the entire side of the house. Once it is level, nails placed 16 inches apart secure its position. Holes in the starter strip make it easy to attach to the house’s wood sheathing. To ensure all the starter strips on all sides of the house are level, all of the strips are typically set before placing any profile pieces in place.
Various pieces of finish trim are available to finish around windows, doors and other features. The most common pieces are J-channel, which looks like the letter “J” in profile, and F-channel. Both types of finish trim nail in place. The vinyl siding then slips into the holding channel.
