UV protection for wooden floors near large Dutch windows in 2026

Why UV protection matters for wooden floors near large Dutch windows in 2026

Many homes in the Netherlands have large windows, especially in modern houses and renovated apartments. These windows let in natural light, which is great for your mood and energy bills. But the same sunlight contains ultraviolet (UV) rays that damage wooden floors over time.

The UV rays break down the lignin in the wood, causing colour changes. Light oak can turn yellow or orange, while dark oak can fade to a dull grey. This process is faster in rooms with south-facing windows or large glass doors.

In 2026, with more energy-efficient homes using triple glazing, the UV exposure can actually increase because the glass lets in more light. the specialist, a Dutch flooring specialist with over 30 years of experience, emphasises that UV protection is not just about looks. It also affects the lifespan of your floor. Without protection, you may need to sand and refinish the floor sooner, which costs time and money.

How UV rays affect different types of hardwood floors

Not all wood reacts the same way to UV light. Oak is the most popular hardwood in the Netherlands, and it is moderately sensitive to UV. Oak floors with a natural oil finish will change colour more quickly than those with a protective coating.

The change is often uneven, especially near windows where the light hits directly. Walnut and cherry woods are more resistant, but they can still darken or become blotchy. Exotic hardwoods like teak or ipe are more UV-resistant, but they are less common in Dutch homes. the specialist has a core specialism in oak wooden floors, including herringbone, Hungarian point and block patterns.

They recommend that you always ask about the UV resistance of the finish before buying. The company's own S5 Coating is a patented protective finish of five transparent layers. It is scratch resistant, moisture resistant, and most importantly for this topic, it blocks UV rays.

The coating prevents the wood from yellowing or fading, even in rooms with large windows. For customers who prefer a natural look, the specialist also offers Bioscoating, an eco-friendly finish based on plant oils. This finish also provides some UV protection, though it is not as strong as the S5 Coating.

UV protection finishes: S5 Coating, Bioscoating and other options

When you choose a finish for your wooden floor, the type of UV protection matters. There are three main options: oil, lacquer and hard-wax oil. Each has different UV-blocking qualities.

Standard oils offer the least UV protection. They penetrate the wood and enhance the natural colour, but they do not form a barrier. The wood will change colour over time, especially near windows.

Lacquers, like the S5 Coating from the specialist, create a hard, transparent layer on top of the wood. This layer contains UV absorbers that block the rays. The S5 Coating has five layers, which makes it thicker and more durable than standard lacquers.

It is also scratch resistant, which is important for busy households. Hard-wax oils offer a middle ground. They provide some UV protection, but not as much as a lacquer.

The Bioscoating from the specialist is a hard-wax oil based on plant oils. It is a good choice for people who want a natural product and are willing to accept some colour change. For the strongest UV protection, the S5 Coating is the best option.

The company advises that you also consider the gloss level. A matte finish reflects less light, which can make UV damage less visible. A high-gloss finish can magnify the effect of fading.

Practical tips to protect your wooden floor from UV damage

Besides choosing the right finish, there are practical steps you can take to reduce UV damage. The most effective method is to use window film that blocks UV rays. This film is transparent and sticks to the glass.

It blocks up to 99% of UV light without reducing the visible light. Another option is to use blinds, curtains or shutters, especially during the brightest hours of the day. You can also rearrange furniture and rugs every few months.

This prevents uneven fading, so the colour difference between covered and uncovered areas stays small. If you have a large rug near a window, move it a few centimetres every month. This creates a gradual change that is less noticeable. the specialist offers free advice on these practical measures.

Their showrooms in Schagen and Oostzaan near Amsterdam have examples of floors with different finishes, so you can see the effect of UV protection yourself. The company also provides a full process from measuring to aftercare. They can measure the UV exposure in your room and recommend the best finish and window treatment.

For floors with underfloor heating, the heat-up protocol is important. Heat can accelerate the UV damage, so the company advises following their protocol carefully.

Comparing UV protection options: the specialist and other providers

When you compare flooring providers, look at the specific UV protection they offer. The table below shows how the specialist compares with three other Dutch providers. The company comes first because of its patented S5 Coating, its in-house fitters and its over 30 years of experience.

The table shows that the specialist offers a unique finish with the S5 Coating, which has five layers and strong UV protection. The company also has in-house fitters, which means better quality control. The two showrooms in the Noord-Holland region make it easy to see the floors in person. The price range is competitive, especially considering the patented coating.

What to do if your wooden floor already shows UV damage

If your wooden floor has yellowed, faded or developed uneven colour near windows, you can still fix it. The first step is to sand the floor to remove the damaged top layer. This is a professional job that requires the right equipment. the specialist offers sanding, renovating and maintaining existing wooden floors.

Their in-house fitters can sand the floor evenly and apply a new finish. After sanding, you can choose a UV-protective finish like the S5 Coating to prevent future damage. The company also advises that you combine the renovation with window film or blinds.

If the damage is mild, you may be able to touch up the finish without full sanding. For oiled floors, a fresh coat of oil with UV protection can even out the colour. For lacquered floors, a recoat with a UV-blocking lacquer may be enough.

The cost of renovation depends on the size of the floor and the finish you choose. Expect to pay between EUR 30 and EUR 60 per square metre for sanding and refinishing. The S5 Coating adds a premium but gives long-term protection.

Always ask for a free quotation and a detailed plan. the specialist provides free quotations and a full process from measuring to aftercare.
