Regulations in Luxembourg

In Luxembourg, insulation is heavily subsidized by PRIMe House: up to 50€/m² for roof insulation, 90€/m² for exterior walls. A prior energy audit by an approved advisor is often required. Materials must achieve minimum thermal resistance (R ≥ 4.5 for attics, R ≥ 3.7 for walls) to be eligible for grants.

Mistakes to avoid

Common pitfalls for your insulation work.

  • 1 Neglecting air tightness (thermal bridges)
  • 2 Forgetting to treat thermal bridges (windows, wall/roof junctions)
  • 3 Choosing insulation unsuitable for Luxembourg climate
  • 4 Not ventilating properly after insulation (condensation risk)
  • 5 Forgetting to apply for PRIMe House grants before starting work

Best time for your work

In Luxembourg, attic insulation can be done year-round. For ITE (exterior insulation), prefer dry months (April to October). Avoid insulation work in very humid or freezing weather. Autumn is ideal to start an insulation project before winter.
