Insulation and energy-focused renovation in Leuven
For renovation projects in Leuven, we assess how walls, roofs and facades can be technically improved without relying on a one-size-fits-all solution.
Insulation and facade works in Leuven
Discover our insulation, facade and moisture treatment solutions in Leuven. We assess each property to determine the most suitable technical solution.
Cavity wall insulation
→Cavity wall insulation
→Professionally insulate an existing cavity wall with Isomo EPS beads to improve thermal comfort without major interior work.
Roof insulation
→Roof insulation
→Roof insulation with URSA glass wool, IKO PIR or EPS for certain loft floors, matched to the roof construction and how the loft is used.
Render
→Render
→Exterior render with external wall insulation for a renewed and better insulated façade. Nu-Isoleren uses Hisfa nv EPS insulation boards from Hulshout.
Façade cleaning
→Façade cleaning
→Professionally remove moss, algae, deposits and atmospheric dirt using a cleaning method suited to the façade.
Façade waterproofing
→Façade waterproofing
→Treat a suitable façade with a water-repellent hydrofuge to reduce absorption of wind-driven rain and better protect the masonry.
Rising damp
→Rising damp
→Have rising damp correctly diagnosed and treat the lower wall zone with a suitable injection system.
A technical insulation approach for homes in Leuven
A renovation in Leuven may combine several goals: reducing heat loss, renewing an ageing facade or improving roof insulation. We therefore start by analysing the existing construction.
Cavity wall insulation is suitable when the cavity allows it. For a complete facade renovation, external insulation with render may be more logical. Roof insulation is adapted to the available construction.
Which solution is suitable for your home?
In Leuven, the insulation choice is aligned with both the renovation goal and what the existing property technically allows.
Cavity wall insulation
If your property has a suitable cavity wall, cavity wall insulation can be an efficient way to reduce heat loss through the external walls.

When the exterior facade requires a more extensive renovation, external insulation boards can be combined with a new rendered finish.

A poorly insulated roof can cause significant heat loss. Depending on the roof structure, we use materials such as glass wool or PIR insulation.
