The project Façade, flat roof and windows completely renewed
In Ghent we renovated the entire building envelope with one goal: less heat loss, more comfort and a better EPC score. We started with the flat roof and the windows, and finished with a clean rendered façade. The result: a home with a modern look, high-quality materials and a clear step forward in energy performance.
The project was carried out with one fixed point of contact, from intake to handover. Thanks to three specialised crews — roof, windows and façade — the scheduling ran efficiently and in a controlled way.
- Façade insulation with render (premium finish)
- Impact-resistant plinth
- Windows and sills: aluminium, anthracite, energy-efficient
- Flat roof: insulation and waterproofing
How we went about it 6 steps, one point of contact.
Phase 11 point of contact
From start to handover, one fixed contact person for all questions and decisions.
Phase 23 fixed crews
Roof, windows and sills, façade and render — each crew specialised in its trade.
Phase 330 days
From start to handover: efficient planning and execution.
- Phase 4
1.5–3 months' waiting time
Average waiting time until the start — transparent and known in advance.
- Phase 5
Fast communication
Clear updates focused on planning and quality.
- Phase 6
High-quality materials
Very satisfied client — no compromises on quality.
What we carried out
Façade insulation with render (premium finish)
- 14 cm of façade insulation with λ = 0.032 for strong thermal performance
- Render finish: Caparol Thermosan K15
- White render for a timeless, clean façade
- Black L-profile at the roof edge for a modern line
Impact-resistant plinth
- Plinth insulation in XPS, 12 cm
- Plinth finish: Decostone durable mineral quartz resin, anthracite
Practical and aesthetic: a robust base with a clear visual transition.
Windows and sills: aluminium, anthracite, energy-efficient
- Anthracite aluminium windows for more energy savings
- Aluminium sills: old sills removed and replaced
- Extra XPS insulation under the sills against heat loss at critical connections
- A better EPC score thanks to high-efficiency glazing
Flat roof: insulation and waterproofing
- 14 cm of PIR roof insulation
- Two layers of roofing with all the necessary connections
- A technically correct flat roof build-up
A technically correct roof build-up focused on durability and reliability.
Rainwater drainage renewed
- Gutters and downpipes replaced for a neat finish and good drainage
The result What the renovation delivered.
The biggest losses first
Roof, façade and windows: in Ghent we deliberately tackled the biggest heat losses together, in a logical order.
Grants
The client received all available grants for roof and façade insulation and window replacement (subject to the conditions).
Design in advance
Before the start we prepared a complete file and design; the client chose the look based on our proposals — as standard and free of charge.
30 days
From start to handover, with one point of contact.

Anyone renovating in Ghent gains the most by tackling the biggest heat losses: roof, façade and windows. By first renewing the roof and windows and then finishing the façade, the process stays logical, efficient and technically correct.
