1-3/4″ Thick – Interior Door
1-LITE GLASS, Interior Door, 1-3/4” Thick
Glass doors, also called “lited” doors, include panes of glass allowing light to pass through the door. The panes can be individual lites, with each pane enclosed and sealed in slotted stiles or mullions (called True Divided Lite, or TDL), or one large pane covered with a false mullion overlay (called Simulated Divided Lite, or SDL). On custom doors, glass can be combined with panels or planks. Sun Mountain offers over 30 glass styles available on custom doors (see www.sunmountaindoor.com).
This 1-lite door is made at our northern Colorado factory. The 1-lite door is available for Interior applications only—not as an Exterior door. We source Knotty Alder lumber from responsibly managed forests in the northwestern U.S.
Key elements of this door include:
This door includes an industry leading Warranty, with one-year limited coverage on unfinished (raw) doors, and five-year limited coverage on factory pre-finished doors. This extended five-year warranty applies only to the construction of the door, and not the factory pre-finish itself.
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 Laminated Veneer Lumber (LVL) core material. Our LVL core is manufactured with a vertical layup, with laminated layers positioned at a 90° angle to the veneer surface for maximum stability.
This door is manufactured with clear, 1/4” thick, single glaze (meaning single pane) glass. The glass is tempered for both building code compliance and safety.
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.
This door features a “C” (concave and convex curved) sticking profile as shown below. “Sticking” is the decorative trim wood placed between the stiles and rails and the glass of the door.
