Not every opening needs a powered door. Sometimes PVC strip curtains or a flexible swing door are all you need; at other times, saving on the closure means losing heat, time and safety. Here is how to tell when a non-motorised closure is sufficient and when a high-speed door is the better investment.
Non-motorised closures
PVC strip curtains
StripGO PVC strip curtains are the most economical and quickest solution to install: always in stock, with virtually no maintenance. They divide internal areas, limit dust and draughts and let people and forklifts pass through without stopping.
Flexible swing doors
The FlexGO swing door is suitable for openings with frequent pedestrian traffic: it is used as a simple barrier to separate warehouse areas from those open to the public.
Sliding curtains
The PolyGO sliding curtain is an economical, non-motorised closure for large external openings with little traffic, such as the gable ends of mobile tunnels.
When PVC strip curtains are enough
- internal separation between departments at similar temperatures;
- frequent pedestrian passages to public areas;
- large openings with very few passages per day;
- limited budget and the need for an immediate solution.
When you need a high-speed door
- Temperature differences: towards cold rooms or the outside, a high-speed door closes in a few seconds and reduces losses (see high-speed doors for cold rooms);
- Forklift traffic: strips get damaged and reduce visibility, while a self-repairing door withstands impacts;
- Hygiene and safety: food environments or controlled atmospheres require dedicated versions;
- Wind: exposed façades need a door such as VertiGO.
Quick comparison
| Criterion | Strips / swing doors | High-speed door |
|---|---|---|
| Investment | Very low | Higher |
| Thermal insulation | Limited | Good, very fast opening |
| Forklift traffic | Rapid wear | Designed for intensive cycles |
| Visibility | Decreases with wear | Vision panels and clear opening |
| Installation | Immediate | With drive and safety devices |
A mixed solution
Often the best choice combines the two: high-speed doors on busy openings and towards the outside, strips or swing doors on secondary internal passages. To choose the right high-speed door model, read how to choose an industrial high-speed door.
Frequently asked questions
Do PVC strip curtains insulate against the cold?
They reduce draughts and losses, but with large temperature differences a high-speed door insulates much better.
How long do PVC strip curtains last?
It depends on traffic: with frequent forklift passages they wear out faster. StripGO strips are easy to replace and always available from stock.
Which door should be used to separate a warehouse from a public area?
For frequent pedestrian traffic, the FlexGO swing door is a simple and economical solution.
How can the gable end of a mobile tunnel with few passages be closed?
The PolyGO sliding curtain is designed precisely for large external openings with low traffic.
