FIB-R-DOR | Division of Advance Fiberglass LLC

FIB-R-DOR'S superior construction and cost-effectiveness is the result of corrosion resistant FRP panels and end-grain balsa cores. Only balsa wood core material is used to construct the FIB-R-DOR system because of its exceptional bondability, high impact/fatigue resistance, and outstanding strength and light weight. Other outstanding features of our door panel include its superior sound and thermal insulation properties and its high moisture resistance.

	In sandwich structures, the FRP skins are comparable to the flanges of an omni-directional I-beam; the core plays the role of the web, carrying shear and local compression loads. End-grain balsa has exceptional shear, compressive and tensile strength values making it especially advantageous for use as door core material.

This magnified drawing clearly reveals the natural honeycomb structure of balsa. Balsa has a much more favorable strength-to-cost ratio than synthetic honeycombs and substantially greater strengths and better cost-effectiveness than synthetic foams. When choosing your next industrial fiberglass door, specify the FIB-R-DOR system with balsa wood cores.* *Reprinted with permission of Baltek Corporation.
