1-3/8″ Thick – Interior Door
1-LITE GLASS, Interior Door, 1-3/8” Thick
Glass, or “lited”, doors include panes of glass allowing light to pass through the door. Glass doors can be one large pane covered with a false mullion overlay (called Simulated Divided Lite, or SDL), or the panes can be individual lites, with each pane enclosed and sealed in slotted stiles or mullions (called True Divided Lite, or TDL). Glass in custom doors can be combined with panels or planks. For custom doors, Sun Mountain offers over 30 glass styles (see www.sunmountaindoor.com). This 1-lite door is made in the U.S.A. at our northern Colorado (near Fort Collins) factory. The 1-3/8” thick 1-lite door is available for Interior applications only, not for Exterior doors, and is often purchased as a pair used as a “French” door. Our Knotty Alder lumber is sourced from the western U.S., from responsibly managed forests.
Key elements of this door include:
An industry leading Door Warranty is provided for 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 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 TimberStrand® Laminated Strand Lumber (LSL) core material.
This door is manufactured with clear, 1/4” thick, single glaze (meaning single pane) glass. The glass is tempered for both safety and building code compliance.
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 beveled sticking profile as shown below. “Sticking” is the decorative trim wood placed between the stiles and rails and the glass of the door.
