Installing an internal glass partition: prepare each stage
Published on 31 July 2026 · Verified on 18 September 2026 · The Mestravaux.lu team
The process starts with the opening: does it exist, require a partition alteration or involve the supporting structure? Resolve this before ordering. Then define approvals for manufacture and installation; no single lead time covers all these situations.
The essentials in 30 seconds
- Define use and opening before selecting the product.
- Have substrate and preliminary work assessed.
- Assign the survey that releases manufacture.
- Separate supply, installation and making good in the quote.
- Take handover with care documentation.

Describe requirements and use limitations
Specify room, light, privacy, door and intended separation. Check the system’s application: Sogal explicitly excludes showers, guarding and outdoor installation for its internal glazing. Similar appearance does not establish suitability for another function.

| 1. Relevé sur place | ≈ 1 heure | Généralement gratuit |
| 2. Devis détaillé | 5 – 10 jours | Structure, vitrage, finition, porte détaillés |
| 3. Fabrication atelier | 2 – 4 semaines | 1 200 – 4 500 € selon surface et porte |
| 4. Pose sur site | 1 – 2 jours | Inclus dans le devis |
| 5. Renfort mur porteur (si besoin) | +1 – 2 semaines | +2 000 – 4 500 € |
Délais indicatifs hors période de forte demande (printemps-été), où les carnets de commandes des métalliers peuvent allonger l'étape de fabrication.
Assess the opening before removal
Provide available drawings, photographs and alteration history. A competent professional should establish wall function, services and necessary investigations. One visit cannot guarantee resolution of every unknown. Where structure is involved, define design, supports and preliminary work; an IPN beam is not an automatic answer.
Check formalities
Contact the municipality before undertaking alterations. Guichet.lu directs enquiries to the municipal service; the page is being updated. Confirm requirements for your project and address.
Approve the survey and manufacturing drawing
Assign final measurement and its timing relative to masonry and flooring. Identify dimensions, grid, door, opening direction, glass, colour and interfaces. Clarify adaptation to uneven substrates and approval of changes. Initial client measurements are not manufacturing approval.
Your project deserves an accurate estimate — it's free.
Request a quoteAccept a clearly scoped quotation
Separate paid visits or design, opening preparation, partition, transport, handling, fixings, seals, waste and surrounding decoration. Agree taxes, payments and schedule. Neither free visits nor excluded finishes are universal. Fast production does not prove poor quality, and a long lead time does not prove hand manufacture.
Coordinate installation
Confirm delivery route, handling area, furniture protection and substrate readiness. Agree whether rooms remain usable during work. Opening and finishing work affect the programme; do not promise same-evening use. The installer must follow the chosen system’s documentation.
Inspect and retain references
Check appearance, alignment, door operation, interfaces and compliance with the approved drawing. Record reservations and resolution. Obtain glazing and hardware references, cleaning instructions and use limits. Ask when seals and finishes allow normal use and whom to contact for adjustments.
Frequently asked questions
How many weeks should I allow?
Request a programme tied to actual approvals and supplies. No local average is established here.
Is the visit free?
Confirm before booking, including measurement, design and travel charges.
Can the metalworker handle everything?
Depending on the offer. Identify responsibility for structure, masonry, installation and finishes.
Is reinforcement always necessary?
No. Assess the existing opening and structure; a glass partition alone does not establish a need for a beam.
Can I use the room immediately?
Confirm readiness after installation, seals, painting and related work. Immediate use is not guaranteed here.
