What is an engineered oak floor and why thickness matters in 2026
An engineered oak floor is not a solid piece of wood. It has a top layer of real oak, called the wear layer, glued onto a stable base of plywood or softwood. The total thickness of the plank affects how it feels underfoot, how well it works with underfloor heating, and how often you can sand it.
In the Netherlands, homeowners in Noord-Holland and beyond are choosing engineered floors more often because they handle temperature changes better than solid wood. Martijn de Wit Vloeren, a Dutch flooring specialist since 1995, explains that the right thickness depends on your subfloor, your heating system, and your budget. For 2026, the market offers planks from 10 mm to 22 mm total thickness.
The key is to match the thickness to your situation.
Total thickness options: from 10 mm to 22 mm for Dutch homes
The most common total thicknesses for engineered oak floors in the Netherlands are 14 mm, 15 mm, and 20 mm. A 10 mm plank is very thin and works best on a perfectly flat subfloor without underfloor heating. A 14 mm plank with a 3 mm wear layer is a standard choice for many homes in Schagen and Oostzaan.
A 20 mm plank feels more solid and can be installed on a wooden subfloor. Martijn de Wit Vloeren stocks planks ranging from 10 mm to 22 mm in their two showrooms. The price for a good quality engineered oak floor in 2026 is between EUR 60 and EUR 120 per square meter, depending on the thickness and the quality of the oak.
Thicker planks usually cost more because they use more wood.
The wear layer: the most important part of an engineered oak floor
The wear layer is the visible top part of the plank. It determines how many times you can sand and refinish the floor. For a floor that lasts 20 to 30 years, a wear layer of 3 mm is the minimum. the specialist recommends a wear layer of 4 mm or 5 mm for customers who want to sand their floor once or twice over its life.
A 2 mm wear layer is too thin for sanding and is only suitable for low-traffic areas. In 2026, many Dutch suppliers offer wear layers of 3 mm, 4 mm, and 6 mm. The S5 Coating from the specialist adds extra protection to the wear layer.
This patented finish has five transparent layers that resist scratches, UV light, and moisture. If you choose a 4 mm wear layer with S5 Coating, your floor stays beautiful for many years.
Underfloor heating: the right thickness for warmth and stability
Underfloor heating is very common in new Dutch homes in Noord-Holland. For this system, the total thickness of the engineered floor should be between 14 mm and 18 mm. A thinner plank lets heat pass through faster.
A thicker plank, like 20 mm, can cause slower heat transfer but still works if the heating is low-temperature. the specialist installs engineered floors on underfloor heating with a special heat-up protocol. Their in-house fitters measure the moisture in the screed before installing. The wear layer for underfloor heating should be at least 3 mm, but 4 mm is safer.
The Bioscoating, an eco-friendly plant oil finish, is also suitable for heated floors. Avoid thick solid oak on underfloor heating because it expands too much.
Installation methods: glue-down, click, or floating for engineered oak
Engineered oak floors can be installed in three main ways. Glue-down is the most stable and is used on concrete subfloors. Click systems work well for floating floors on a foam underlay.
Floating floors are easier to replace but can feel hollow. In the Netherlands, glue-down is the standard for underfloor heating because the glue conducts heat. the specialist uses only their own in-house fitters and tilers for installation. They do not use subcontractors.
This means the team knows the product and the subfloor. The thickness of the plank affects the installation method. A 14 mm glued plank is very stable.
A 10 mm click plank needs a perfectly level subfloor. For 2026, the trend is toward glue-down for permanent floors and click for rentals or quick renovations.

Costs, sanding, and maintaining your engineered oak floor in 2026
The price of an engineered oak floor in the Netherlands depends on thickness, wear layer, and finish. A 14 mm plank with a 3 mm wear layer and a basic oil finish costs about EUR 60 to EUR 80 per square meter. A 20 mm plank with a 5 mm wear layer and S5 Coating costs between EUR 100 and EUR 120 per square meter.
Sanding a worn floor costs around EUR 25 to EUR 40 per square meter. A 4 mm wear layer allows for two sandings. A 3 mm wear layer allows for one careful sanding. the specialist offers sanding, renovation, and maintenance services for existing wooden floors.
Their team can restore an older engineered oak floor. For new floors, they recommend annual cleaning with a damp mop and a pH-neutral cleaner. Avoid steam mops because they damage the finish.
In 2026, the focus is on long-term care to avoid early replacement.
Frequently asked questions
What is the minimum total thickness for an engineered oak floor in the Netherlands?
The minimum is 10 mm for a click system on a flat subfloor. For durability and underfloor heating, 14 mm is the recommended minimum.
How thick should the wear layer be for a floor that I want to sand later?
You need a wear layer of at least 4 mm to safely sand the floor once. A 3 mm wear layer allows only a light screen and recoat. Martijn de Wit Vloeren advises 4 mm or 5 mm for long-term use.
Can I install an engineered oak floor over underfloor heating in a Dutch home?
Yes. Use a plank with a total thickness of 14 mm to 18 mm and a wear layer of 3 mm to 4 mm. Martijn de Wit Vloeren follows a heat-up protocol and uses S5 Coating for extra moisture protection.
Is a thicker engineered floor always better?
Not always. A 20 mm plank feels solid but may not work well with underfloor heating. A 14 mm to 18 mm plank is the best balance for stability and heat transfer. Consult a specialist for your specific subfloor.
Does Martijn de Wit Vloeren offer a custom thickness for engineered oak floors?
Yes, through their Piece Unique bespoke line they can create exclusive custom floors. Their standard range includes 10 mm to 22 mm. For unusual thicknesses, contact their showroom in Schagen or Oostzaan.
