FiberWrap Seamless Doors

Our doors are made with our unique FiberWrap™ technology (check out the video on this page) and are designed to withstand the pressures and forces found in tornadoes and hurricanes. In order to pass the ASTM E330/E330M-14 test, the door had to be able to sustain forces up to 150% of those you might experience in such a natural disaster. Shelter Works FiberWrap™ doors passed with flying colors!

Shelter Works’ FiberWrap Seamless Doors™ are designed and built using our proprietary process to maximize long-term performance. We form our doors in a two-part mold under pressure and our fiberglass actually wraps seamlessly around the core, creating an incredibly tough and durable door that will withstand decades of use and exposure without failure.

Seamless, Integrated
Door Jamb Construction

Our seamless, integrated door jambs are formed into the wall during the molding process, so they’re not separate pieces that are later cut in, or adhered some way, or screwed together as other manufacturers sometimes do.  These very wide  jambs are about 5 inches deep and prevent wind-blown debris, dust, rain from penetrating into the building. They can be placed anywhere on the wall– to the left, to the right, up or down.

High Quality Door Closers

The door is the #1 stress point for every shelter because the door is the one thing on a building that you interact with, so our doors need to be solid, operate smoothly and provide a sense of security. Three heavy duty stainless steel ball-bearing hinges and an industrial hydraulic door closer ensure that the doors will operate smoothly, even in severe weather. Both our standard 3-point and optional panic hardware have their latching mechanisms surface mounted on the inside surface of the door so that the latches cannot be tampered with from the outside, making them very secure.
