Sectional, up-and-over or roller garage doors: check the space
Published on 4 August 2026 · Verified on 18 September 2026 · The Mestravaux.lu team
The door must work with your car, storage, ceiling and pedestrian access. Before choosing a finish, request its occupied volume throughout movement. Opening width alone cannot select the mechanism.
The essentials in 30 seconds
- Draw the door open, closed and moving.
- Check passage, obstacles and mechanism servicing.
- Plan garage access during failure.
Identify product movement
Hörmann distinguishes rising sectional panels, a tilting single panel and rolling above the opening, plus side-sectional doors. These families guide comparison; the model drawing establishes actual space requirements.
| Contrainte | Sectionnelle | Basculante | Enroulable |
|---|---|---|---|
| Plafond occupé | moins adaptée | rails possibles | avantage |
| Recul extérieur | pas nécessaire | à vérifier | pas nécessaire |
| Linteau réduit | système à adapter | possible selon modèle | coffre contraignant |
| Maintenance | rails et ressorts | mécanisme simple | tablier et coffre |
Cette grille prépare la comparaison ; elle ne remplace pas le diagnostic du support et du produit précis.
Have clearances surveyed
Request clear passage, headroom, side room, occupied depth and any outward swing. Describe access slope and nearby road or internal door. Check clashes with lights, pipes and storage. Do not choose roller or sectional solely on a space-saving claim.
Define garage use
Describe parking, workshop, storage and pedestrian routes. If insulation, light or acoustics matter, request complete-product data and proposed junctions. Clarify ventilation needs before changes; do not block an existing opening for appearance or insulation.

Request a quoteSpecify motorisation and backup access
Identify motor, controls, supply and safety devices intended for the assembly. Without another entrance, ask how access works during failure. Have release demonstrated according to instructions. Safety checks belong to the installer; never use a body as a test obstacle or work on springs.
Compare work and arrange handover
Separate door, motor, controls, electrical work, removal and finishes. Ask about maintenance, spares and mechanism access. Request demonstration of a full cycle, controls and manual-prescribed checks. Keep references, documents and written defects with agreed follow-up.

Frequently asked questions
Is a roller door always most compact?
Check housing, guides and final passage on the model drawing. Results depend on the garage and installation.
Does an up-and-over door swing outside?
Request the exact movement path of the offered variant and check available space.
Is motorisation included?
Have motor, controls, connection and commissioning listed in the price.
Which type insulates best?
Compare data for offered assemblies, seals and fitting. Mechanism alone proves no performance.
