Windows and doors cost in Luxembourg 2026

The following prices reflect supply and installation costs observed in Luxembourg in 2026. All figures include removal of existing windows/doors, supply of new units, installation and basic finishing (rendering fill, interior trim). Scaffolding is separate and typically runs €500–2,000 depending on the number of floors and access difficulty.

Prices include 17% VAT unless the work qualifies for the 3% reduced rate on a principal residence inhabited over two years. Standard window replacement qualifies for 3% VAT — always confirm with your installer before signing.

The frame material is the single most consequential decision in a window replacement project. It affects cost, thermal performance, maintenance burden, and resale value — all of which matter significantly in Luxembourg's demanding property market.

PVC frames The most affordable option and the most commonly installed across Luxembourg. PVC performs excellently for thermal insulation, requires virtually zero maintenance and has a lifespan of 30–40 years. Its limitation is aesthetic: it is not permitted on many historic facades, classified buildings or communes with strict urban planning guidelines. In Luxembourg City's historic districts, check with the service urbanisme before specifying PVC.

Aluminium frames The premium choice for modern architecture, commercial buildings and the upper end of the residential market. Aluminium is significantly stronger than PVC for the same profile size — allowing larger glazed surfaces and slimmer sight lines, which is why it dominates in contemporary new-build developments like Cloche d'Or or Belval. Modern aluminium frames incorporate a thermal break to prevent heat transfer; without it, aluminium is a thermal disaster. Always specify the thermal break grade.

Wood and wood-aluminium composite The traditional choice for historic Luxembourg townhouses and rural properties. Solid wood frames have excellent thermal performance and can be repaired rather than replaced. The downside is maintenance: unpainted or unlacquered wood requires treatment every 8–12 years. Wood-aluminium composites (wood interior, aluminium exterior cladding) are growing in popularity — they combine the warmth of wood inside with the durability of aluminium outside, with minimal maintenance.

Triple glazing has become the de facto standard for new builds in Luxembourg since the 2017 building regulations tightened minimum U-value requirements. But for renovation projects, the choice between upgrading to double or triple glazing requires a careful cost-benefit analysis.

Understanding U-values The U-value measures how much heat passes through the window per square metre per degree of temperature difference. Lower is better.

Is triple glazing worth it in Luxembourg? For homes being renovated with the intent to reach energy performance class A or B (required for Klimabonus at higher subsidy tiers), triple glazing is generally necessary. The additional cost of triple vs double glazing is typically €150–300 per window unit — this is recovered through lower heating bills in approximately 12–20 years at current energy prices.

For homes where windows are being replaced on a budget and the rest of the building envelope is not being upgraded simultaneously, high-performance double glazing (low-e, Uw ≤ 1.1) often represents better overall value.

Luxembourg-specific energy pricing context Luxembourg's residential gas price is regulated, but electricity costs have risen significantly since 2022. Heat pump owners — a growing segment in Luxembourg — benefit most from triple glazing as the reduced heating load directly reduces electricity consumption.

Practical advice Always ask your window installer to provide the certified Uw values for the products being quoted. Never accept informal descriptions like "high performance" — request the datasheet.

A front door in Luxembourg serves multiple functions: thermal performance, acoustic insulation, security and aesthetic impact on one of Europe's most competitive property markets. It is also the single most visible element of a home's exterior — and buyers notice.

Security classifications European resistance class (RC) ratings define how long a door resists an attempted break-in using specified tools:

RC2 is the minimum standard for new residential builds in Luxembourg. Most insurers offer premium reductions for RC3 and above — ask your home insurer before specifying.

Price ranges by specification

Acoustic performance For apartments in Luxembourg City — particularly near the ring road, train stations, or the airport approach path — acoustic insulation (Rw rating) is as important as thermal performance. Look for doors rated Rw ≥ 42 dB for urban locations. Acoustic-grade doors typically cost 10–20% more than equivalent non-acoustic models.

Installation timing Front door replacement in Luxembourg typically takes 1 working day. Bespoke or non-standard sizes (common in older Luxembourg townhouses with unusual proportions) require 6–10 weeks of lead time from order.

The Klimabonus programme, administered by myenergy.lu, provides direct subsidies for energy renovation works in Luxembourg. Window and door replacement is among the eligible categories — but the subsidy is conditional on meeting specific performance thresholds and following the correct application procedure.

What qualifies To be eligible for the Klimabonus window subsidy, the new windows must meet minimum performance criteria:

• Uw ≤ 1.1 W/m²K (overall window thermal transmittance)
• Ug ≤ 0.8 W/m²K (glazing thermal transmittance, for triple glazing)
• Installation must be carried out by a registered professional holding an autorisation d'établissement

Subsidy amounts (2026 indicative) Subsidies are calculated per square metre of window surface replaced:

• Standard subsidy: €30–50/m² of glazing replaced
• Enhanced subsidy (prime majorée, income-based): up to €80/m²
• Additional bonus for certified installers (QualiWatt or equivalent): +€10–15/m²

For a typical 10-window house replacement (~25 m² of glazing), the base subsidy amounts to €750–1,250 — meaningful but not transformative relative to total project cost.

Application procedure — critical steps

1. Obtain quotes from at least one registered professional
2. Submit your Klimabonus application via myenergy.lu BEFORE works begin
3. Keep all invoices and product datasheets (Uw certification required)
4. Submit completion documents within 12 months of application approval

Do not start work before receiving application approval — retroactive applications are not accepted. The myenergy.lu platform provides a pre-check tool to confirm eligibility before you apply.

Front doors and roller shutters Insulated front doors (with documented U-value ≤ 1.2 W/m²K) and insulated roller shutter housings may also qualify — check the current myenergy.lu catalogue for exact eligibility conditions, as these are updated annually.
