QUASART in Sanem — thermal insulation and renovation
Sanem is one of the major communes of southern Luxembourg, with its districts of Sanem-Centre, Soleuvre, Belvaux and Ehlerange. Home to 17,600 residents, it features a predominantly residential housing stock — 1960-90s single-family homes, former workers’ estates linked to the region’s steelmaking history, and recent residences benefitting from the dynamic of the neighbouring Belval district (just 2 km away).
The need for energy renovation here is massive. A large share of Sanem houses were built between 1960 and 1990 with thermal standards now obsolete: uninsulated block walls, insufficient roof insulation, marked thermal bridges. Well-sized EWI (16-20 cm of EPS or rock wool) combined with roof insulation transforms energy performance: heating savings of 50-70%, improved summer comfort, increased property value. The Klimabonus programme makes these investments accessible to most households.
QUASART favours three systems suited to Sanem’s mixed residential profile: heavy hydraulic render EWI for maximum thermal performance on collective housing, ETICS thin-coat EWI for price-quality ratio on single-family homes, wood-fibre bio-based EWI for owners sensitive to summer comfort and carbon footprint. Lacquered steel metal cladding and Cedral fibre cement complete the offering for expressive renovations.
Based in Crauthem (L-3327), we reach Sanem in 10 minutes via the A4. Proximity to Belval and Esch-sur-Alzette enables travel pooling and competitive pricing in southern Luxembourg — an advantage for co-ownerships and individuals sensitive to total project cost.

Yes — they are even the ideal target profile for EWI. These houses generally have uninsulated block walls or insufficient cavity insulation (4-6 cm). 16-20 cm of EWI transforms them into high-performance homes: heating savings of 50-70%, improved summer comfort, increased property value. QUASART delivers free assessment and accurate pricing at your home.
Yes. Soleuvre, Belvaux and Ehlerange are part of the commune of Sanem — QUASART works there on every facade, EWI, cladding and renovation project. Belvaux in particular, close to the Belval district, sees growing demand for renovation to enhance existing buildings.
For a 200 m² facade house in Sanem, expect €25,000-45,000 incl. VAT installed depending on system: thin-coat EWI ~€120-180/m², bio-based EWI ~€160-220/m², heavy render EWI ~€180-250/m². Includes insulation, render, finish, scaffolding. Klimabonus grants deductible (often €5,000-15,000 depending on performance and income) — free home assessment.
Each quote is studied personally by our team. Depending on project complexity — surface, access, substrate condition, time of year — you receive a detailed quote or a follow-up call. Standard EWI on a single-family home generally requires 3-6 weeks of work, weather permitting. Simple projects move quickly; complex ones get the time they deserve.
Klimabonus is open to all Luxembourg households for EWI works on primary or secondary residences. The amount depends on thermal performance achieved (minimum R required), building type and household income. QUASART systematically verifies your eligibility, sizes the project to optimise the grant and guides you through the procedure. Visit myenergy.lu to simulate.
