What does a PVC dormer cost?

PVC is the most common cladding on prefab dormers in the Netherlands and the UK. It is also the most price-competitive option — but the spec sheet matters more than the headline number.

Short answer

A 3-metre PVC dormer with HR++ glazing typically lands between €8,500 and €14,000 installed. Multi-wall PVC profile systems and PVC-Trespa hybrids sit at the top; basic single-wall PVC sits at the bottom.

Realistic price ranges

  • Basic single-wall PVC, 3 m: €8,500–€10,500.
  • Multi-wall PVC profile, 3 m: €10,500–€12,500.
  • PVC-Trespa hybrid, 3 m: €12,000–€14,000.
  • Add per extra metre: €1,500–€2,200.

What drives the price

  • Profile system (single-wall, multi-wall or hybrid with Trespa).
  • Insulation Rc value — Rc 4.5 baseline, Rc 6.0+ pushes price.
  • Glazing: HR++ baseline, triple adds €400–€800.
  • Lead apron, zinc trim and gutter style.
  • Crane access and street logistics.

PVC vs timber

PVC wins on purchase price and short-term maintenance: no paint cycles, easy cleaning. Timber wins on repairability and lifetime cost — a damaged PVC panel often means replacing a whole face, while timber can be patched and repainted indefinitely.

Veelgestelde vragen

01What does a PVC dormer cost in 2026?
Indicatively €8,500–€14,000 for a 3-metre PVC-clad dormer with HR++ glazing, depending on profile system, insulation level and finish.
02Is PVC always cheaper than timber?
On purchase price, yes — usually 20–35% less. Over decades the gap narrows because PVC cladding tends to need replacement before timber does, especially on south-facing roofs.
03How long does PVC cladding last on a dormer?
Modern multi-wall PVC and PVC-Trespa hybrids last 25–35 years if installed with proper ventilation gaps. Without ventilation, UV and heat shorten that to 15–20 years.
Conclusie
PVC is a defensible choice when the spec is honest. Insist on a named profile system, a documented Rc value and a ventilated cladding detail — and the lowest price stops being a gamble.
