Siding Terms Everyone Should Know

When shopping for new siding, you’re likely to encounter unfamiliar words. Siding is an essential component that protects your property from various elements, so knowing its fundamentals would be helpful in your design choices. Understanding the different siding terms also ensures that you are fully aware of the product you’re getting. 

Today, we share a glossary of commonly used siding terms.

  • Batten is a strip of wood sealing the joints of your siding. Modern board-and-batten siding refers to old wood siding with boards and battens to fill the gaps.

  • Backerboard is the flat material applied between the studs and siding to provide an even surface for siding installation.

  • Channel is the area of the accessory trim where the siding or soffit panels are inserted.

  • Course is a row of panels running the length of your property from one side to the other.

  • Eaves are the part of your roofing system that hangs a little over the exterior of your walls.

  • F-Channel is a molding shaped like a letter F. It is used to trim siding installed at a 90-degree angle.

  • Fascia is the trim that covers the ends of roof rafters.

  • Fascia boards are boards attached to the ends of your rafters between the roofing material and the soffit overhang.

  • Head flashing is a piece of trim designed to deflect water away from the vertical siding’s top. This prevents water from penetrating the siding and damaging the backerboard over time.

  • Lug is a snap-lock punch that creates elevated “ears” or tabs on a siding panel. It is used to secure a siding panel after the nailing hem has been removed.

  • Nail hole punches are the holes in the flange of a piece of siding used to secure the siding to a wall using nails.

  • Square is an exactly vertical measurement — 90 degrees from a level surface.

  • Soffit is used to enclose the horizontal underside of an eave, cornice or overhang. It should be installed lengthwise from the wall to the fascia.

  • Underlayments are water-resistant materials installed underneath the siding panels.
