Architectural/Commercial Doors

Lynden Door, Inc. produces Architectural (LD) Series and Commercial (CD) Series doors. These robust wood flush doors incorporate a complete bonded core assembly: the stiles and rails are securely bonded to the core, and then sanded as a complete assembly prior to the application of face veneers.

"Architectural doors per WDMA I.S. 1-A"

LD Architectural Series doors are manufactured to meet or exceed WDMA I.S. 1-A and AWS Standards, Custom Grade and if specified, Premium Grade. The LD series warranty covers interior doors for the life of the original installation.

CD Commercial Series doors are designed for nonresidential applications meeting specific standards of construction. CD Series doors meet WDMA extra heavy duty standards and may be used in applications requiring higher standards than residential; experiencing high traffic; requiring large sizes; heightened security; sound attenuation; and a variety of hardware needs. Bonded sanded cores. 5-year limited warranty.

IC Interior Construction Series: Doors designed for all applications where an architectural door (LD Series) would typically be specified, but where the application is less rigorous than the architectural standard in some regards, and where, therefore, some stipulated exceptions to the LD standard are permissible. Bonded sanded cores. 5-year limited warranty on interior doors.
