Chal-Strip™ flexible dor-closures have a wide range of energy-saving

commercial/industrial application. Use inside and outside to cut the loss of heated or

cooled air. Since Chal-Strips push open and close instantly, unlike ordinary doors, air

transfer is minimized and utility bills are reduced. Traffic can enter and exit quickly

and easily. Chal-strips 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 Chal-Strips. Colored vinyl strips are positioned as aisle guides to prevent vehicles from hitting the sides of doorways. There are no sharp edges, since the strips are extruded with carefully contoured edges.

Chal-Strips-lightweight. flexible, tough and a wise investment in energy savings.

Use Chal-Strlps Throughout Your Plant

The PVC strips are transparent, non-toxic and smooth edged for safety and retain their flexibility to

-20°F. or -40°F. depending on model. Applications for Chal-Strips indoors or outdoors are limited by

your imagination.

Tips to Guide Your Selection

When selecting Chal-Strips, consider the variety of widths, thicknesses 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 thicknesses are relatively easy to pass through, choose the next heavier gauge material or

the next larger over-lap to assure the best results. Wider, heavier strips with greater overlap provide

more resistance in larger 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 useful

in reducing the effect of light breezes. Heavier strips with greater overlap must be used if wind is a

major factor. In windy areas, or under severe noise conditions, the use of two or more strip doors in

sequence will form dead space barriers.
