PVC strip curtains are the most practical low-cost way to control heat loss, dust migration and draughts. But a wrongly sized curtain either obstructs traffic or fails to insulate. Correct specification rests on three parameters: strip size, overlap ratio and material series.
Where Are They Used?
Warehouse doorways, transitions between production areas, cold room and blast freezer entrances, welding bays (dark series) and packing lines are typical applications. At forklift doorways where the door cannot stay closed, curtains also work as a door-curtain combination.
Strip Size and Overlap
Narrow pedestrian doorways take 200x2 mm strips, standard warehouse doors 300x3 mm, and wide, wind-exposed forklift doorways 400x4 mm. The overlap ratio balances insulation against ease of passage: 50-100% full overlap for low-traffic doors, 30-50% for heavy forklift traffic.
Standard or Cold Series?
The standard series works from -35°C to +50°C and suits most indoor use. Cold room and freezer entrances need cold (polar) series PVC that stays flexible at low temperature — otherwise strips stiffen and crack. Clear, light blue and transparent red options are available, plus a sheet series up to 1200 mm width. See our industrial consumables page for details.
Installation Tips
Set curtain height 10-20 mm off the floor (dragging means premature wear), choose a rail system that allows single-strip replacement, and during the first week check that strip ends do not fold at forklift height. Being able to replace one worn strip instead of the whole curtain sharply lowers total cost of ownership.
