Teak is one of the most prestigious woods in the world for windows and doors — and one of the most misunderstood. Clients ask us about it for the wrong reasons (it’s expensive, therefore it must be best) and dismiss it for the wrong reasons (it’s expensive, therefore it must be impractical). After more than twenty years working with European wood windows, here is what actually matters about teak.

Why Teak Stands Apart from Other Hardwoods

Teak contains natural oils and silica that make it resistant to moisture, insects, fungi, and rot — without any chemical treatment. This is not marketing language. The British and Dutch navies used teak for ship decks for centuries because it survived saltwater exposure that destroyed other woods. The same properties that protected wooden ships now protect window frames in coastal climates, humid environments, and projects exposed to extreme weather.

Compared to oak, mahogany, or meranti — all excellent window woods in their own right — teak’s main advantages are:

• Superior dimensional stability: it does not shrink, swell, or warp the way other species can
• Natural resistance to decay without preservatives
• Exceptional hardness for hardware retention (hinges, locks, and handles stay tight)
• Long service life: properly maintained teak windows can last 80 to 100 years

The Real Cost of Teak Windows and Doors

Teak is expensive. There is no honest way around it. As a raw material, premium European-grade teak ranges from $18,000 to $30,000 per cubic meter, depending on the source country (Burma, Ghana, Indonesia, India), the grain, and the age of the timber. By comparison, oak runs around $1,500 to $3,000 per cubic meter.

For a finished window or door, the cost premium for teak over oak or mahogany is typically 40 to 80 percent — sometimes more for fully-glazed doors with large sections.

But the cost question only makes sense when you look at the lifecycle. A teak window installed properly will outlast two or three softwood window cycles. For a luxury home built for a 50-year horizon, the math often favors teak. For a renovation where the building itself may be sold in ten years, it usually does not.

What Teak Looks Like — And How It Ages

New teak has a warm, golden-brown color with rich grain patterns. Over time, exposed to sunlight and weather, it changes. This is the part most people do not expect.

Left untreated outdoors, teak weathers to a soft silver-grey patina. The wood underneath is structurally unchanged — still strong, still rot-resistant — but the surface color shifts dramatically over the first one to three years. Many architects choose teak specifically for this aging quality, particularly on coastal homes and modern designs where the silver patina becomes part of the architectural language.

If you want to keep the original golden-brown color, the wood needs to be finished and maintained:

• A high-quality factory finish at the start (we use Sikkens-grade systems on all our windows)
• Reapplication of teak oil or exterior wood finish every 5 to 7 years on the exterior
• Interior surfaces, protected from UV and weather, generally need no maintenance

There is no “right” choice here — it depends on the look you want and how much maintenance you are willing to commit to.

Where Teak Windows and Doors Make the Most Sense

After two decades, here is where I see teak specified successfully and where I steer clients elsewhere.

Teak makes sense for:

• Coastal and waterfront properties where salt air destroys other woods
• Tropical and subtropical climates with high humidity
• Historic restorations where teak was the original material
• Contemporary architecture where the silver-patina aging is desired
• Luxury projects with a 50+ year horizon
• Exterior doors that take heavy daily use

Teak is usually overspecified for:

• Cold, dry continental climates where oak or larch perform equally well
• Renovations where the property will be sold within ten years
• Projects where the budget is better spent on better glazing or hardware
• Standard residential applications where mahogany or meranti will perform identically at half the cost

Teak Window and Door Configurations We Supply

At Chablais, teak is available across our full product range:

• Tilt-and-turn windows — the European standard for ventilation and easy cleaning
• Casement windows — single, paired, in-swing, or out-swing
• La Française — traditional French casement without a center post
• Fixed windows — in any geometry including arched, circular, and trapezoidal
• Lift-and-slide doors — for terrace and garden openings up to large spans
• Entry doors — solid teak construction with custom hardware
• Folding doors — for full-width opening between interior and exterior

All teak windows can be specified with exterior aluminum cladding or bronze cladding for a hybrid construction that combines teak’s beauty inside with metal protection outside.

Sustainability and Sourcing

Teak has a complicated history. Burma teak (now Myanmar) is the most prestigious but comes with serious sourcing concerns due to political and environmental issues. Today, most responsibly-sourced teak comes from FSC-certified plantations in Ghana, Indonesia, Costa Rica, and Brazil.

We work only with European partners who source from legal, traceable, and sustainably-managed plantations. If sustainability matters to your project, ask your representative for documentation — we provide it on request.

Is Teak the Right Choice for Your Project?

Honestly, for most projects there are better-value options — mahogany, oak, or meranti will give you 90% of the performance at 50% of the cost. But for the projects where teak is the right answer, nothing else comes close.

If you are specifying windows or doors for a coastal home, a luxury build with a long horizon, or a project where teak is part of the architectural intent, we would be glad to discuss your options.
