QUASART — thermal insulation in Strassen
Strassen has kept its character as a high-end residential commune despite the immediate proximity of Luxembourg City and the Belle Étoile commercial zone. The dominant housing stock: family villas built between 1960 and 2000, old manor houses, recent small collective buildings and, along Route d’Arlon, some contemporary developments. For homeowners, the question of thermal insulation typically arises during a comprehensive renovation — facade refurbishment, roof replacement, or extension project.
Three interventions dominate on this typology. Bio-based ETICS (STEICO wood fibre) for facade renovation, because it delivers major thermal improvement, excellent summer comfort (phase shift > 10h) and aesthetics compatible with existing buildings — tinted mineral renders, controlled relief. Attic insulation by blown Rockwool rockwool or cellulose fibre, quick and highly effective (R ≥ 6.0 m·K/W reached at 400 mm thickness). Finally, internal lining (ITI) for facades to be preserved as-is — exposed stone, facades listed by municipal regulation.
From our head office in Crauthem (L-3327), we reach Strassen in 10 minutes via the N3 and Route d’Esch. We work throughout the commune — Strassen centre, Route d’Arlon, eastern residential areas, Belair boundary. Our teams are experienced in projects in suburban zones: neighbour consideration, minimised nuisance, clean and scheduled sites.

FAQ
Frequently asked questions — Insulation in Strassen
Strassen family villas of this period typically have walls in concrete blocks or hollow bricks without insulation, very lightly insulated attics and original single-glazed joinery. The winning combination: bio-based wood-fibre ETICS 140-180 mm on facades plus blown attic insulation (R ≥ 6.0) plus joinery replacement. On a 180 m² villa, heating savings reach 50 to 70% depending on initial condition. QUASART carries out a free diagnosis and sizing.
Yes. QUASART works throughout the Strassen commune — Strassen centre, Route d’Arlon, eastern residential areas, Belair boundary. Our Crauthem head office is 10 minutes away via the N3. We regularly work with private owners, independent architects and small co-ownership managers in the commune.
STEICO wood fibre is particularly relevant for Strassen family villas for three reasons: it offers remarkable summer comfort (thermal phase shift > 10h, essential under roofs for fitted attics), it has a negative carbon balance (CO2 storage during tree growth), and it qualifies for the enhanced Klimabonus premium for bio-based materials. Technically: lambda ≤ 0.038 W/m·K, durability > 50 years, excellent moisture performance.
To reach R ≥ 6.0 m·K/W in the roof (recommended performance threshold in Luxembourg, and minimum to trigger some Klimabonus grants), about: 400 mm of blown rockwool (lambda 0.035), 360 mm of cellulose fibre (lambda 0.040) or 300 mm of wood fibre in panels (lambda 0.038). QUASART generally recommends 400 mm of blown wool in lost attics — unbeatable performance/price ratio.
For a typical Strassen villa (180-220 m² habitable), indicative budgets: facade ETICS 25,000 to 45,000 € (150-220 m² of wall x 120-280 €/m²), blown attic insulation 3,000 to 6,000 €, joinery replacement 15,000 to 30,000 €. Total ambitious energy renovation: 50,000 to 80,000 €, with energy savings of 50 to 70% and property value enhancement. Klimabonus aids to deduct according to eligibility.
Yes. Any significant modification of the exterior appearance of a building in Strassen requires a building permit, issued by the municipal administration. As ETICS changes facade thickness (by 14 to 24 cm additional), some cases also require an implantation study if the plot limit is close. QUASART directs you to the commune urban planning services and coordinates with your architect if necessary.
