Wooden front doors from Kowa
Light is life. Front doors with glass cut-outs ensure that the entrance area is also flooded with light. You can determine the size of the cut-out and choose from a wide range of motifs.
The choice of glass, glazing and accessories also opens up many design options.

We recommend class P4A impact-resistant glass in accordance with the DIN EN 1627 test requirements for burglar-resistant entrance doors in resistance class RC2, which is also recommended by the criminal investigation department.
Nature and technology are combined in wooden entrance doors with a closed door leaf.
Wood – no other material on earth is so alive and so versatile, diverse in structure and color. It is hard, dense and brittle and is highly valued for properties such as resistance and natural beauty.
The strength and character of the grain are determined by the tree species and its location, but even with the same type of wood, no two pieces are the same. The individuality of your front door begins with the choice of wood species.
The wooden front doors are extremely resistant to warping in accordance with DIN EN 1121 and have first-class resilience. You can feel secure thanks to the tested burglar resistance in accordance with DIN EN 1627, resistance class RC2.
The age-old need for protection – even if we are often not aware of it – is still of decisive importance today when choosing a door.
After all, a door must protect us, shield us from noise, protect us from cold or heat and protect our property.

The workmanship is so well thought out and meticulous that the front doors will bring joy for several generations. Nevertheless, you should also check the location of your front door before deciding on the material. The need for care and functionality are decisively determined by the effects of the weather.
Thanks to special impregnation and gluing processes, wooden front doors are protected against the effects of weather, pest infestation and UV radiation on an environmentally friendly basis. Glaze tones bring out the naturalness of the wood and the character is retained even with opaque coatings.
