2-Panel Plank Square Top Rail
1-3/8″ Thick – Interior Door
2-PANEL PLANK SQUARE TOP RAIL, Interior Door, 1-3/8” Thick
Plank doors are similar in design to raised panel doors, but with vertical boards placed side by side filling the width of the panel. Sun Mountain’s custom wood plank doors are often engineered with solid panels, then “v-grooved” to imitate the individual planks. Additional styles include planks running the entire vertical and/or horizontal surface of the door. Our custom wood doors can be viewed at www.sunmountaindoor.com.
This 1-3/8” thick 2-panel plank, square top rail Interior door is made in the U.S.A. at our northern Colorado factory. Our 1-3/8” thick doors can be used for Interior applications only—not for Exterior doors. We source our Knotty Alder lumber in the western U.S., only from responsibly managed forests.
Key elements of this door include:
An industry leading Door Warranty is provided with this door, including one-year limited coverage on unfinished (raw) doors, and five-year limited coverage on factory pre-finished doors. Please note that this extended warranty does not apply to the factory pre-finish itself, but only to the construction of the door.
Engineered Stiles & Rails
Stiles and rails are the vertical and horizontal “frame” components respectively of the door. Our stiles and rails are engineered to resist bowing and warping. We use industry leading 1/8” thick veneers, with superior quality TimberStrand® Laminated Strand Lumber (LSL) core material.
Panels are the large, wider boards used to fill the space between the stiles and rails. Our panels are 11/16” thick solid wood—much higher quality than pressboard panels with thin veneers, or hollow core panels found on lower-quality imported doors. Our panels are manufactured with small width boards which are edge glued to create the larger width panel. Individual boards are random widths, glued in alternating grain patterns to balance the panel and reduce the natural tendency of the wood to warp or cup.
Bore & Dowel Construction
Our doors are assembled with bore and dowel construction. We use industry leading 1/2” diameter dowels. Stiles and rails are bored, glued and then doweled for optimum strength and stability. Panels fit into grooves in the stile and rail components, and “float” on rubber spacers to allow for minor expansion and shrinking of the wood with the natural moisture and environmental changes of the home.
Panel & Sticking Profile
Decorative trim called “Sticking” is placed between the stiles and rails and the panels of the door. This door features a a beveled sticking profile, a notched and gradual bevel panel profile, and “V-Grooves” on the panels which create the plank door appearance as shown below.
