Sectional door vs. roller door – which gap seal is suitable?
The right choice depends on gap dimensions, floor level, and intended use. Here is a clear comparison with recommendations and category links.
Comparison matrix
| criterion | Sectional door | Rolling/high-speed door |
|---|---|---|
| Contact surface | Medium – ideal for normal soils | large – stable on uneven ground |
| Sealing effect | very good with standard columns | very good to widely clefted |
| Assembly | magnetic, fast | magnetic, select profile width |
| use | Garage, workshop, hall | Logistics, Industry, High-speed |
Basic rule: The more uneven the ground , the wider the seal should be.

Does a seal also cover water?
It significantly reduces splashing water and drafts. We also recommend a baseboard/threshold to protect against standing water.
How long will the seal last?
With correct installation and regular cleaning, it is durable; side protection plates increase its service life.
