Interior Commercial Doors (IC)

Interior Commercial (IC) Series

IC 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.

Lynden Door's expertise in the manufacture of Residential (SD Series) doors makes the incorporation of SD materials into an LD "chassis" a excellent choice in select circumstances. In all cases, care must be taken to ensure that the full LD Series doors are not better suited. In no case should an IC Series be substituted for a specification calling for an architectural door. (See LD Series section.)

Significant cost savings are available for the IC Series.

APPLICATIONS & BENEFITS

Specific door configurations within the IC Series include the IC200 (non-rated or 20-minute rated), IC2000 (non-rated or 20-minute rated), IC6000 (60-min rated) and IC 9000 (90-minute rated). Please see detailed PDF spec sheets below. IC Series doors are recommended for a wide range of commercial applications and incorporate a true bonded sanded core assembly exceeding WDMA heavy duty performance standards. Factory clear natural or custom stain finish available upon request.
