QUASART — thermal insulation in Schifflange
Schifflange bears the imprint of the Luxembourg mining basin: a dense urban fabric shaped by the steel industry, with rows of semi-detached workers’ houses built between the 1950s and 1970s to house factory families. This built heritage today represents a considerable potential for energy renovation. Current owners — often first-time buyers or rental investors — are undertaking thermal improvement works on a massive scale to reduce energy bills and enhance their property value.
These semi-detached houses present a specific technical challenge. Front (street) and rear (garden) facades are accessible for classic ETICS — thin render on rockwool 140-160 mm. But gable party walls are inaccessible externally: insulation is then carried out from the interior (ITI) with rockwool or wood-fibre linings on metal framework if the neighbour is not coordinated. Attic insulation (mansard roof or lost attics) is often the fastest and most cost-effective intervention — blown rockwool or cellulose fibre, 1 day of work, R ≥ 6.0 m·K/W achieved.
Our Crauthem (L-3327) head office is 20 minutes from Schifflange via the A13 and N31. We know the local workers’ housing stock well and the type of work expected by Schifflange owners: comprehensive energy renovation, coordinated package (ETICS plus attics plus ITI), Klimabonus application handling, planning that respects neighbours in dense streets. QUASART also works in Foetz (activity zone) on tertiary buildings and light industrial premises.
Our insulation solutions
QUASART insulation solutions in Schifflange
Blown attic insulation
Rockwool Jetrock rockwool or blown cellulose fibre — R ≥ 6.0 m·K/W in 1 day of work. Priority intervention for Schifflange houses with low, poorly insulated roofs.
ITI — Party walls
Rockwool or wood-fibre lining on metal framework internally — essential for gable party walls inaccessible from outside. Optimised thickness 80-120 mm.
Comprehensive energy renovation
Coordinated package ETICS plus attics plus ITI plus optionally joinery — multi-trade approach to halve the consumption of a 1950-1970 workers’ house.

FAQ
Frequently asked questions — Insulation in Schifflange
Schifflange workers’ houses from the 1950s-1970s are generally semi-detached on both sides (shared gables), with only front (street) and rear (garden or yard) facades accessible. The QUASART protocol: ETICS on front and rear facades (targeting R ≥ 3.7 m·K/W), blown attic insulation (targeting R ≥ 6.0), and ITI wood-fibre linings 80-100 mm on both gable party walls. This triptych eliminates 80-90% of losses in a typical house and massively improves winter and summer comfort.
Yes, it is recommended to inform adjacent neighbours upstream of the ETICS project, even though legally no authorisation is required from them for work on your own front and rear facades. Reasons: scaffolding may overhang the boundary, site dust circulates, and above all, ETICS coordinated with the neighbour (if rear facades are aligned) allows economies of scale and a more homogeneous visual result. QUASART can establish a joint quote if both owners agree.
In Schifflange semi-detached houses, gable walls shared with neighbours are inaccessible externally as long as the neighbour does not undertake their own works. ITI (interior insulation) allows unilateral action: rockwool or wood-fibre lining 80-120 mm installed on metal framework on the interior side, then plasterboard facing. The drawback: slight loss of habitable surface (a few m² overall). The advantage: real thermal gain and enhanced acoustic treatment with the neighbour.
For a typical Schifflange workers’ house (100-140 m² habitable), the comprehensive energy renovation package generally costs between 25,000 and 45,000 €. Typical breakdown: front + rear facade ETICS 80-120 m² (15,000-30,000 €), blown attic (2,500-5,000 €), ITI party walls 40-60 m² (4,000-8,000 €), labour and scaffolding included. Klimabonus aids may cover a significant share of the total cost depending on current eligibility criteria.
Yes. QUASART works in the Foetz activity zone on light tertiary buildings, heated storage premises, workshops and associated offices. On this type of building, ETICS is often installed in parallel with cladding replacement — an ideal opportunity to combine thermal insulation with aesthetic modernisation. Site constraints (business continuity, logistics flows) are integrated from the planning stage.
Any modification of a building’s exterior appearance in Schifflange requires a building permit issued by the municipal administration. For semi-detached houses in the centre, adding ETICS thickness (14-24 cm) can raise questions regarding roadways and plot boundaries — a slight encroachment on the pavement may require a municipal waiver. QUASART supports you in compiling the application and directs you to an architect if the project requires it.
