Your home’s siding makes up a significant portion of your home’s exterior and provides crucial protection against moisture. It needs regular maintenance and, at some point, replacement.

Make sure you know these important siding terms so you can better communicate with your contractor when planning your siding replacement.
Backerboard
This flat material is situated between the studs and the siding material. It ensures the siding has an even surface during and after installation.
Buttlock
The buttlock locks itself onto the preceding panel and improves siding structure and attachment. It is usually at the bottom edge of siding panels.
Channel
These are the channels in accessory trims where contractors insert siding panels. Contractors may also refer to the trim as channels with designations such as J-channel and F-channel.
Course
The course is a row of panels that run the house’s length from one side to another. For vertical siding, a course runs from the top to the bottom of the house.
Drip Caps
Drip caps are also known as head flashing. These are installed alongside vertical siding. Their job is to ensure that water won’t infiltrate the panels.
Face
This is the visible side of the panel, so it directly affects your home’s aesthetic appeal.
Flashing
These thin metal strips are usually positioned behind J-channels, windows and corner posts. They help keep the water away from the house.
Furring Strip
This is a thin strip of wood that contractors use to even out a surface before they install vinyl siding. Furring refers to the act of applying these strips.
Lap
A lap refers to siding overlap. It means to overlap two siding panel ends to allow expansion and contraction as the outdoor temperature changes.
