Glossary of Terms

Arched Trim A radius or curve in the trim design, typically in the top section of the door. The arch is made to a specific radius or template.
Astragal Also know as Bottom Weatherstrip. This piece of material helps protect the bottom of the door from the elements.
Bead Board Typically, 1x lumber which has been shaped with 1/8" rounded beads running vertically down the board. Can also be plywood grooved in this fashion.
Checking Cracks or chinks within the wood material.
Clear Lumber A high grade of lumber that is typically knot free. Some grades of wood species may have small pin or tight knots.
Curing The preserving of your wood door. The drying time of a paint of stain as it penetrates and reacts with the surface of the lumber.
Kerf A groove or notch made by a cutting tool. Our facing material is kerfed to minimize the warping and cupping of the lumber.
Fingerjoint The joining of smaller pieces of wood to create a longer piece.
Full Vertical Lift A tracking system used in situations where the ceiling is extremely high and the garage door has room to lift straight up. The track extends above the header and continues upwards beyond the height of the opening.
Galvanizing Zinc coating to protect steel against corrosion.
Header A framing support running across the top of the garage door opening.
Headroom The measurement from the top of the door opening up to the lowest obstruction of the garage. Obstructions may not be above header – look into garage. 18" is ideal for a standard installation.
Hi-Lift Track A tracking system used when the ceiling is unusually high, but the door must still retract to a horizontal position. As with Full Vertical Lift, the track extends above the header and continues upwards beyond the height of the opening. A portion of the door ends up horizontal when in the open position.
Insulation Material that has the ability to reduce heat or cold transmission. In our doors, 1 1/4" polystyrene placed inside the flush door frame between the back and facing material.
Jamb The vertical framing on each side of the garage opening. This is where the vertical portion of the track is mounted on the inside of the garage.
Mullion A support or framing piece of lumber that divides individual panes of glass.
Overlays Window designs, typically made with the same wood material as the door panels, created with a pin router. Standard and custom designs can be made. Normally, seen on the top section of a panel door in front of a similar sized piece of glass.
Paint Grade Wood material not suitable for staining.
Panel A flat, usually rectangular piece forming a raised, recessed, or framed part of the surface in which it is set.
Rail & Stile Millwork The horizontal (rail) and vertical (stile) material which make up the framework for a panel door.
Raised Panel A panel in which the panels are machined on the edges to create a raised center portion.
Recessed Panel A panel in which the panels are not raised. Typically, plywood is used in this application.
Section Separated by the horizontal breaks in the door. The sections are stacked on top of each other in the opening and put together with hardware. Each section rolls individually through the track system, similar to a train.
Side Room The space on each side of the door opening to the nearest obstruction inside the garage. 3 1/2" is the minimum requirement per side to attach the track system.
Stain Grade Doors created with lumber which is suitable for staining. Not all plywood is acceptable for staining.
True-Divided Lites Individual panes of glass divided by mullions on a window section. Typically used on flush doors.
