Frequently asked questionsYour questions
Your questions
about QUASART
Find answers to the most common questions about our services and how we work.
QUASART operates across four areas of excellence: ventilated facades (wood, HPL, metal, stone, zinc cladding), external thermal insulation (EWI/ETICS), high-end interior and exterior renovation, and architectural 3D visualisation through our Immersioo service.
No. QUASART operates in Luxembourg, France (Lorraine, Alsace, Grand Est) and Belgium, covering the entire Greater Region. For projects outside this area, we review each request on a case-by-case basis.
Every quote is personally reviewed. Depending on your project's complexity — surface area, system, access constraints — you receive a detailed estimate or a call to discuss. Simple projects move fast. Complex projects deserve the time we dedicate to them.
QUASART is a Luxembourg company (RCS B253631) with AXA decennial insurance (policy 10/0214108). Our teams are trained to the applicable DTU standards — DTU 41.2 (curtain wall cladding), ETAG 004 (EWI ETICS) — and to the specific requirements of the Luxembourg market.
