Hinged patio doors or sliding doors: choose the usable opening
Published on 4 August 2026 · Verified on 18 September 2026 · The Mestravaux.lu team
No universal width makes sliding doors the necessary replacement for hinged patio doors. Draw the route outside, furniture and required passage, then compare feasible configurations for that opening.
The essentials in 30 seconds
- Compare clear passage rather than frame width alone.
- Have opening, threshold and floor levels drawn.
- Separate building alterations from door supply.
Define passage and movement
Request drawings of the hinged leaf’s travel and the sliding unit’s fixed and moving parts. Record clear opening, handle position and occupied zones. Test a representative model: sliding does not by itself describe effort or available passage.
| Besoin | Porte-fenêtre | Baie vitrée |
|---|---|---|
| Largeur modérée | solution directe | possible mais pas toujours utile |
| Pas de débattement | moins adaptée | avantage du coulissant |
| Grande lumière | profils plus présents | grande surface vitrée |
| Entretien | paumelles et joints | rails et drainage |
Cette grille prépare la comparaison ; elle ne remplace pas le diagnostic du support et du produit précis.
Identify system options
Schüco lists different track configurations and an optional zero threshold for ASS 50. This illustrates why the ordered variant matters; these features do not describe every sliding door.
Have threshold and junctions designed
Request a section showing internal floor, terrace or balcony, threshold and planned drainage. Assign substrate alterations and junction work. Assess step-free passage within the whole project rather than inferring it from a product photograph.
Your project deserves an accurate estimate — it's free.
Request a quoteDistinguish replacement from alteration
Have the building assessed before ordering if enlarging the opening. Guichet directs alteration permits to the municipality, with local exceptions for some minor work. Check the applicable process; the official page is marked as being updated.
Compare equivalent final results
Request visible glazing, fixed parts, documented performance and proposed shading. Separate product, transport, possible lifting, removal, junctions and finishes. Add structural assessment and work where needed. An existing opening and an enlarged one are not directly comparable prices.

Frequently asked questions
Does sliding always provide more passage?
Request the actual open passage for the proposed configuration, not overall width.
Do sliding doors automatically insulate less?
Compare documented product performance and conditions rather than ranking opening types alone.
Does a low threshold guarantee accessibility?
Assess levels, passage and complete use. A product option does not certify the project.
Can the opening be widened without further assessment?
Check structure and permissions before ordering. This guide approves no specific wall alteration.
