The way to open the door

If the vestibule or hall in your home is not too large, it is worth using outward opening doors. However, you should pay attention to the material from which the door is made and take care of a roof to avoid scratching, e.g. after snowfall. Inward opening doors are a perfect solution for houses with a larger vestibule.

Left or right wing door

There are situations where the position of the hinge matters. When choosing the right or left door, take into account that they have adequate opening space and will not interfere with the door inside your home.

Fashionable appearance

The doors also have a decorative function. In our offer you will find, among others doors with glass elements, which will additionally illuminate the interior of the hall and allow you to see who came to visit. Modern glass in the door is extremely resistant and does not reduce the level of security.
