Custom Wooden Window Frames Made to Measure

Solid wood frames with HR++ or triple thermal glass — built in our Brussels workshop, fitted to your exact opening.

A well-made wooden window frame outlives PVC and aluminum by decades. We craft each frame to your opening from Nordic pine, spruce or oak, fit it with HR++ or triple-glazed insulating units, and finish it the way you want — natural oil, lacquered colour, or paint-grade primer. Every frame leaves our workshop with SKG3-certified hardware, factory-fitted seals and a 10-year warranty.

Why solid wood still beats PVC and aluminum

Wood has the lowest U-value per profile depth of any common frame material. It expands and contracts predictably, holds its seal for decades, and ages gracefully — three reasons heritage and characterful homes almost always specify it. With modern thermal-break joints, our wooden frames hit U-values that match or beat premium PVC and aluminum systems.

Made in Belgium, installed across the Benelux

Our workshop is in Anderlecht (Brussels). We measure your openings on-site, manufacture the frames over 2–3 weeks, then install them in 1–2 days per opening. Installation teams travel anywhere in Belgium and the Netherlands — from Antwerp and Ghent to Amsterdam, Rotterdam and The Hague.

Subsidy paperwork included

For Dutch clients we prepare the documentation needed for ISDE and SVVE subsidy claims. For Brussels and Walloon clients we provide the technical attestations for Renolution and Wallonie Énergie premium applications.

Materials

  • Nordic pine — best price/durability balance
  • Spruce — light, knot-free, paint-grade
  • European oak — premium, naturally rot-resistant
  • Optional thermal-break joints for triple glazing

Frequently Asked Questions

How long does manufacturing take?

Typically 2–3 weeks from design sign-off, plus 1–2 weeks lead time for measuring and quote. Large or arched profiles may add a week.

Can you match an existing heritage profile?

Yes. We can replicate ovolo, lambs-tongue and other traditional mouldings on the new frames so they look identical to the originals — but with modern insulating glass inside.

Do you handle painted or stained finishes?

Both. We supply primed (for site painting), factory-painted in any RAL colour, or stained and oiled for a natural wood look.
