Internal wooden windowsill – Oak
The windowsill is handcrafted from sustainable European oak in Germany with quality workmanship. For our windowsills, we only use glued A-grade oak. Oak wood is one of the most sought-after types of wood because it combines many special properties. This is especially true for indoor window ledges. The firm, dense structure ensures excellent stability and impressive load-bearing capacity.

40mm thickness of the wooden windowsill
We offer our interior window sills in 40mm thickness because it is the most robust option and sets us apart from all other providers. We do not sell boards that bend and will soon need to be replaced. Dimensionally stable and durable.

Fastest delivery in Germany
Unlike other suppliers, we deliver your wooden windowsill not in weeks, but in 3 days. Everything is carefully packed and prepared for quick shipping. Perfect for urgent construction sites.

No doubling
Unlike our competitors, we do not double up our wooden window sills. Doubling up is a cheap way to get away with using the term "solid oak". But in reality, we are the only provider that offers interior wooden window sills made of genuine solid oak.

Regular maintenance
Every 3-4 months, the superficial protection of wooden window sills wears off. It is therefore necessary to regularly maintain the surface. This is even much simpler than one might think. All you need is our in-house care set. Samuel explains in the video how to use it.

Why buy a wooden windowsill online?
Because online is simply faster. If you go to the carpenter, joiner, or hardware store around the corner, many things are left open and the production is usually lengthy and complex. And if you still have any questions, you can either write us a message via the contact form, write via WhatsApp, or conveniently call us at +4922619694951
How do I attach the board to my windowsill?
Most people use mounting adhesive for this purpose. This is a solution to permanently install the windowsill. Some simply lay it on and secure it in other ways. In any case, you should leave a 1mm gap between the wall and the wooden board, as wood is a living material that works and can easily change shape depending on temperature and humidity.
Can I return wooden window sills?
Basically, yes. You can return the windowsills within the statutory withdrawal period. Unfortunately, cut-to-size windowsills can only be returned as a gesture of goodwill. This is always decided on a case-by-case basis.
Can I also use the windowsill outside?
Whether you install the wooden windowsill indoors or outdoors is entirely up to you. However, our windowsills are exclusively designed and coated for indoor use. We assume no liability for any outdoor use. A wooden windowsill indoors quickly deforms when weather conditions fluctuate, which is why we recommend wooden windowsills indoors only for indoor use.

Drying
A protracted process
The drying process is so important because it guarantees the dimensional stability of the oak planks. Only good drying ultimately guarantees a good end product.
Cut
Every move is perfect
Of course, some of the work is done by machine, but the most important processes, such as the correct cutting and selection of the planks, are entirely in the hands of the craftsmen.
Surface treatment
Millimeter-perfect work
This process is carried out by our meticulous craftsmen, who must sand, brush, and prepare the wood correctly to ensure that neither too much nor too little wood is removed.
Coating
Long-lasting surface finish
Similarly, our finished products are coated by hand and carefully laid out to dry. This process is repeated two or three times, and requires experience and a trained eye.
