Chalfant strip door flexible dor-closures have a wide range of energy-saving commercial/industrial applications. Used inside and outside to cut the loss of heated or cooled air. Since strip doors push open and close instantly, unlike ordinary doors, air transfer is minimized and utilty bills are reduced. Traffic can enter and exit quickly and easily. Strip doors also provide an effective barrier against birds and insects, dust debris, drafts, smoke, fumes and noise. The annoying sound of operating machinery and equipment is greatly reduced.

Safety is another important reason for specifying strip doors. Colored vinyl strips are positioned as asile guides to prevent vehicles from hitting the sides of doorways. There are no sharp edges, since the strips are extruded with a carefully conture edges.
Strip doors are lightweight, flexible, tough and a wise investment in energy savings.

The PVC strips are transparent, non-toxic and smooth edged for safety and retain their flexiblity to -20ºF. or -40ºF. depending on the model. Applications for Chal-Strips are limited by your imagination.

When selecting Chal-Strips, consider the variety of widths, thickness and percentage of overlap. Mounted strips hang in a concave/convex overlap pattern that permits interlocking to form a good barrier seal. Narrower, thinner strips with less overlap are easier for personnel to penetrate. However, since all thickness are relatively easy to pass through, choose the next heavier gauge material or the next larger overlap to asure the best results.

Wider heavier strips with greater overlap provide more resistance in large openings. Use full overlap when strips are to be used as a sound barrier. Strip doors will not stop strong winds or handle extreme negative pressure conditions and are usefull in reducing the effect of light breezes. Heavier strips with greater overlap must be used if wind is a major factor.
