Warehouse Door Strip Curtain - Select Your SizeStart saving energy by installing a Strip Curtain on your warehouse door today! From walk through doors to large forklift doors to loading docks, Strip Curtains are a cost effective solution to keep heated or cooled air inside, and dust and noise outside, while allowing people and equipment to move right through. The flexible plastic strips can be easily parted by people and forklifts, then fall right back into place to seal off the doorway again.
