Industrial halls in autumn – reducing energy losses through doors
When it gets colder outside, energy costs rise. With suitable gap seals on gates, doors, and ramps, you can immediately reduce energy losses – without major remodeling.
Why act now?
Autumn/winter means: temperature differences increase, air exchanges faster – through gaps in doors, sides, and on the floor. Every leak acts like a permanently open window.
With magnetic gap seals, you can close these weak points quickly and cleanly: better temperature stability, less draft, less dust – and measurably lower energy consumption.
The big leaks – where energy escapes
Sectional doors
- Bottom edge to the ground (uneven surfaces, settlements)
- Side guide & reveal
- Joints in the panel area (drafts in the surface)
Roll-up & high-speed doors
- Floor connection at high frequency
- Side areas in case of negative/positive pressure in the hall
Loading technology
- Gap between bridge/ramp and hall floor or wall
- Hinge side (rear) – often overlooked
Steel & side doors
- Floor joint and side joints
- Leaky frames in older existing systems
Sliding doors
- Overlapping area of the leaves
- Floor/ceiling guidance on uneven surfaces
Solutions by gate/door type (with direct links)
Sectional doors – fast, robust sealing
Robust, magnetic seals in variable lengths and widths are suitable for the bottom edge and wide gaps. Optionally, they come with integrated rodent protection for sensitive areas.
To the sectional door seals bottom edge sides rodent protection optional
Roller doors & high-speed doors – tight at high speeds
Speed counts here: flexible, magnetic systems reliably seal the floor area, keep the sides sealed and are durable – even with frequent use.
For roller shutter/high-speed seals 1–9.2 m sets width variants
Loading technology – gap gone, energy in
Ramps and bridges cause massive leaks. Special profiles for the front and hinged sides (rear) reduce leakage by orders of magnitude – quick to install, requiring minimal tools.
For loading technology seals 4–30 mm gap (typ.) hinge side
Steel doors – side doors finally draught-free
Magnetic door seals can be cut to size and installed tightly. Ideal for utility, basement, and side doors—in many cases, no drilling required.

Sliding doors – problem area overlap
Profiles are available for sliding doors that reliably seal the overlap and the floor area. This reduces drafts and dust ingress into production areas.

Measurement in 10 minutes & installation instructions
Measurement checklist
- Length: measure the usable opening width (left–right).
- Gap dimension: largest dimension in operating condition (check several points).
- Surface: magnetic? → Direct mounting; otherwise, provide adapter tape.
- Frequency: high clock speed → choose more robust/wider profiles.
Assembly summary
- Clean surfaces, dry/grease-free.
- Align the profile, place it in place and press it evenly .
- For doors, cut to length if necessary and deburr edges.
- Test run, check tightness, fine-tune.
Tip: Side protection plates provide additional protection for seals on roller/high-speed doors against rodents
Economic efficiency: Example calculation & ROI
Even small gaps cause significant losses. Waterproofing often pays for itself within one heating season.
| parameter | Example | comment |
|---|---|---|
| Number of goals | 8 | Logistics hall |
| Gap per gate | 20 mm × 3.5 m | Floor/side |
| Operating time | 10 hours/day · 5 days/week | October–March |
| Energy price | e.g. 0.18 €/kWh | company-specific |
| Savings potential | high | Depending on the gate type/gap & use |

Practical examples from companies
Goods receipt (high-speed)
Floor and side sealing reduces drafts; compressor/heating load decreases; employees report more stable temperatures.
Production (sectional door)
Bottom edge sealed, dust load noticeably lower; fewer quality deviations in sensitive areas.
Ramp (loading technology)
Front and hinge side sealed: less cold air in the front zone, electric doors no longer ice up in frost.
FAQ
How do I choose the right width?
Orient yourself to the largest gap (e.g., 20–30 mm). For rolling/high-speed operation, also consider the operating frequency.
Does the seal adhere to aluminum/stainless steel?
Yes, with a suitable adapter tape for non-magnetic surfaces. We can advise you on the right combination.
Can I install it myself?
For doors and smaller gates: yes, with care. For ramps/industrial facilities, we recommend a service call.
Is this approved for fire doors?
No. Door seals are not approved for fire doors. Please refer to the regulations.
How long does such a seal last?
Depending on usage, cleaning, and initial loading. Typically several years; side protection plates increase service life.
