Burglar-resistant windows: define reinforcement and verify the offer
Published on 4 August 2026 · Verified on 18 September 2026 · The Mestravaux.lu team
Start with your home’s access points and the products actually offered. Distinguish claimed system performance from adding an accessory. Aim for defined protection you can use daily, without promising an opening becomes impossible to breach.
The essentials in 30 seconds
- Assess access points and existing windows before allocating money.
- Request documents for the ordered configuration.
- Check locking, maintenance and use at handover.
Prepare a home assessment
The Police prevention service offers free advice and visits by appointment. Prepare an opening plan and your questions for that assessment.
| Couche | Question au devis | Limite |
|---|---|---|
| Vitrage | quelle composition ? | ne protège pas le cadre |
| Quincaillerie | quels points ? | dépend du profil |
| Poignée | quel verrouillage ? | accessoire isolé insuffisant |
| Pose | quelle fixation ? | support à contrôler |
Cette grille prépare la comparaison ; elle ne remplace pas le diagnostic du support et du produit précis.
Separate recommendations from obligations
The Police leaflet recommends RC2 for new or altered windows and P4A laminated glass. This is prevention advice, not an absolute-security guarantee.
Request evidence for the offer
Identify model, dimensions, opening type and included components. Where a class or test is claimed, request its document and confirmation that the ordered variant falls within scope. A handle-only or glass-only answer does not address a whole-window question.
Your project deserves an accurate estimate — it's free.
Request a quoteAssess retrofit options
Before adding reinforcement, have frames, fixings and accessory compatibility examined. Record what remains, changes or is excluded. Do not infer a resistance class merely from a new lock. If replacement and adaptation are feasible, request separate offers describing each solution’s outcome.
Prepare handover and everyday use
Request a closing and unlocking demonstration for relevant occupants. Report rubbing or operating difficulties. Keep references, evidence and maintenance instructions. Have compatibility with ventilation and required exit routes checked; do not improvise permanent blocking of an opening.

- Security door or reinforcement: decide after assessing the existing doorYou want to strengthen the entrance while perhaps retaining its appearance. Establish what can remain and what must change first. Reinforcement, an upgraded lock and a complete doorset do not necessarily describe the same work or evidence.Read the guide

Frequently asked questions
Does a lockable handle prove RC2?
Request evidence covering the whole system and configuration. An accessory name does not demonstrate the class.
Does triple glazing prove security?
No. Identify security characteristics and supporting evidence separately from pane count.
Should every window receive the same equipment?
Have actual access and use assessed. This guide sets no universal floor-based priority.
Will the stated class satisfy my insurer?
Send the exact description and documents and request confirmation of its requirements. Coverage is not guaranteed here.
