What size opening is required for a 90 cm door with a fixed frame?
Are you wondering what size door opening with a fixed frame will be most suitable for a 90 cm door? Precise preparation of the opening in the wall is the key to success when installing a 90 cm door with a fixed frame. This size is often chosen for living room doors or main apartment doors, providing a wide passage. Correct dimensions will not only ensure an aesthetic appearance, but above all the stability and durability of the entire interior door structure. Understanding how to prepare an opening for a 90 door with a fixed frame is fundamental for anyone who wants the installation to run smoothly and without problems.
For 90 cm doors with a fixed frame, the recommended wall opening width is 1022 mm. This dimension is optimal because it takes into account both the width of the frame itself and the necessary installation clearance. This clearance, usually about 1-2 cm on each side, is extremely important. It allows for easy manoeuvring of the door frame during installation, enabling it to be perfectly levelled and aligned. In addition, this space is necessary to fill with installation foam, which permanently stabilises the door frame in the opening and provides additional acoustic and thermal insulation.
The fixed door frame for 90 cm doors is most commonly used for walls of standard thickness. It features a simple, non-reinforced design, which makes it a popular choice due to its reliability and ease of installation in a properly prepared opening. It is a solid and economical solution for your interior doors. However, if your walls are of non-standard thickness, e.g. very thick, consider using an adjustable door frame, which will better adapt to the specific characteristics of the wall.
How to measure a hole in a wall?
Always remember to carefully measure the opening at several points – at the top, in the middle and at the bottom – both in width and height. Any unevenness can significantly hinder installation and prevent the 90 door with a fixed frame from fitting perfectly. Also, make sure that the surface of the opening is clean, dry and free of loose plaster before proceeding with the installation. Paying attention to these details when preparing the opening for a 90 door with a fixed frame will result in an aesthetic and functional solution that will last for many years.
