Classic wood windows - the advantages in detail

5-year warranty

You don't change windows every day. It is therefore important that the window 'settles' well, especially in the first few years. Changes due to sunlight or weather conditions should be avoided as much as possible.

You have a 5-year warranty on all wooden windows . This means that you can rely on us for good quality and enjoy your windows for many years.

Blue stain protection: particularly effective against discolouration

Wood is a natural material. Unfortunately, staining or rot can result if moisture does get in. This bluish discolouration is not only visually unattractive, but also weakens the material of your window. To protect the wood from moisture, we recommend using a deep penetrating wood preserver. This "blue stain protection" with immersion primer penetrates deep into the wood and builds up moisture-regulating protection.

High-quality surface thanks to hydroplaning

This innovative method of machine planing gives the wood surface of your windows and balcony doors a particularly smooth, elegant, and high quality appearance. Since the wood fibre is not only flattened on the surface, but cut off, the pores remain open. This allows the primer to penetrate deeply, permanently and protectively into the wood. Your advantage: a permanently beautiful look and high-quality windows that you will benefit from for a long time.

Grade 1a wood

Window construction requires the use of high-quality wood without knots, discolouration or large pieces of resin. The reason for this lies in both the desired look for the customer, but also in stability and durability .

Wooden scantlings of all kinds are layer-glued and furnished with continuous cover slats. Finger-jointed timbers are not used, which guarantees warp-free frames with smooth and gentle closure.

High-quality components from well-known manufacturers

We only use the highest quality components on your windows and doors, from well-known manufacturers whose quality we know and trust. This applies to the handles from Hoppe, the glazing from Glas Fandel, and the fittings from Siegenia Aubi and Winkhaus.

All of our components must meet our "German brand quality" standards, so that we can guarantee the longest possible service life for your windows.

Good value wood windows made of pine, larch or Meranti

High-quality woods such as pine, larch or Meranti form the basis of our wood windows in the IV78 system. In the Classic wood window profile, our offer ranges from normal windows to thermally insulated, security or soundproof windows. We also offer sliding windows as well as balcony doors and patio doors in the IV78 classic system. With its clear contours, the striking wood window profile has a very long service life, as it is protected over the long term thanks to the special processing. We produce wood windows in the most modern technical facilities, where they are manufactured using the highest quality energy-saving systems, and following the latest ecological developments.

Over 5 generations of experience

We have been manufacturing and developing wood windows since 1872. Thanks to our many years of experience, we can definitely say that the wood windows from windows24.com are very good value, and very high quality.

By default, the surfaces are finely planed, which allows for an excellent colour finish, which in turn protects and preserves the wood. The sash cover profile provides our wood windows with additional protection from the weather conditions.
