Tilt-and-turn and side-hung wood windows combine natural insulation, visual warmth and respect for the building. Oak, meranti or laminated pine depending on the project: the only material that can be restored rather than replaced, ideal for a home with character or a listed renovation.
The benchmarks that matter for a wood window fitted by our teams, on an everyday opening. Concrete figures, not marketing.
Wood insulates naturally, with no strip or air chamber: its low conductivity makes it one of the best frame performers. Paired with double or triple glazing, the whole unit (Uw) reaches the level of a high-performance renovation.
Oak for nobility and hardness, meranti (a tropical wood) for its stability against moisture, laminated pine for an excellent price/stability ratio. We choose the species based on the exposure and budget of the window.
Wood works like no other material: windows with glazing bars, bonded or integrated muntins, mouldings and original profiles reproduced exactly. Essential to respect an old or listed building.
A well-maintained wood window easily passes 40 years, and above all it can be restored: you sand, fill and re-stain rather than replace. An advantage neither PVC nor aluminium offers.
Clear or tinted stain that lets the grain show through, or opaque paint in a microporous finish in any RAL shade. We adapt the protection system to each window’s exposure.
Contrary to popular belief, maintenance is spaced out: a refresh of stain or paint every 8 to 12 years depending on exposure. Modern microporous finishes have greatly extended this cycle.

No material is perfect for every opening. Here, honestly, is where the wood window excels and where it’s better to look elsewhere.
It comes into its own whenever you want character, natural insulation or respect for an existing building. A few cases where it shines:
On an old facade, the wood window extends the style: mouldings, muntins and stained shades that match the building rather than betray it.
In a protected zone or on a listed monument, wood is often the only material allowed. We reproduce the original profiles exactly, window by window.
For those who want a renewable material, natural insulation and the warmth of wood inside, with no compromise on performance.
For the warmth of wood inside with no outdoor upkeep, look at wood-aluminium. And for the best insulation/price ratio on everyday openings, the PVC window stays unbeatable.
On this mansion in a protected zone, the authorities required keeping the original glazing-bar windows. We fitted oak windows reproducing the muntins and mouldings exactly, with high-performance double glazing built in without betraying the look. Modern comfort, facade intact.

Wood wins on natural insulation, character and respect for the building. Compare it point by point to PVC and aluminium, then open the material that interests you.

Far less than it used to. Modern microporous finishes have stretched the cycle: you refresh the stain or paint every 8 to 12 years depending on exposure. A full-south window or one badly battered by rain will need slightly tighter upkeep, but we’re a long way from the yearly repaint of old.
Oak for nobility and hardness, meranti (a tropical wood) for its great stability against moisture, laminated pine for an excellent price/stability ratio. We choose based on the window’s exposure and budget: a more stable wood is justified on the most exposed facades.
Yes, and even better than aluminium. Wood has low thermal conductivity: it insulates naturally with no thermal break or air chamber. Its frame performance is among the best, neck and neck with PVC. Paired with the right glazing, the unit reaches the level of a high-performance renovation.
It’s often the only material allowed. In a protected zone or on a listed monument, the authorities generally require wood and the retention of the original profiles. We reproduce glazing bars, muntins and mouldings exactly, with high-performance double glazing built in without betraying the look.
It’s one of the great strengths of wood: depending on the condition, you sand, fill, replace the glazing and re-stain rather than throw everything out. On old or listed buildings, this restoration preserves the original joinery while improving insulation. We assess window by window what can be salvaged.
Grants depend on the performance achieved (Uw value), not the material. A high-performance wood window qualifies, depending on your region and income, for a renovation grant and 6% VAT for homes over ten years old. We handle the paperwork for you.
