FORT® Honeycomb Door Series:

FORT® Honeycomb door has a paper honeycomb core. The core is permanently bonded to door skins strengthening the structural integrity of the door, enhancing long term performance and durability, while significantly reducing the weight.


FORT® door is constructed with HONICEL paper-honeycomb from the N.L.

 

Honeycomb was developed as a structural core for military aircraft wings during World War II. Among its advantages are a high strength-to-weight ratio, uniform crushing strength, high shear strength, and excellent impact resistance. It is durable, can be treated to resist decay and insects. The rigid honeycomb structure is integrated with door to form hundreds of small I-beams with the door, with a uniform thickness and flat surface that makes it easy to add lites, louvers or other features. It reinforces the full width and height of the door. Door edges are mechanically interlocked the full height of the door. Top and bottom inverted channels provide stability and protection. Bevelled hinge and lock edges allow for tighter installation tolerances, to ensure easier operation and eliminate binding and sticking.

 

FORT® Honeycomb construction is in compliance with SDI-100 standards (ANSI A250.8-1998). Hardware preparation, reinforcement and locations are in accordance with ANSI A- 250.6-1997 and SDI 129-00. Honeycomb core doors are recommended for interior and exterior applications. Honeycomb core have integral high resistance to impact damage. Calculated thermal conductivity factors and STC rating for Honeycomb core doors are as follows.
