Are you planning to install a 90 door with an adjustable door frame and wondering what size opening would be most suitable for a 90 door with an adjustable door frame? This wider version of an interior door is often chosen for spacious living room doors or as the main door to an apartment. Choosing the right dimensions for the opening in the wall is essential for successful door installation, and is particularly important in the case of adjustable door frames for 90 cm doors. These door frames offer flexibility in adapting to different wall thicknesses, but require precise preparation of the opening. Remember that the type of door frame – rebated or non-rebated – affects the final dimensions of the opening.
Rebated door frame
For 90 cm doors with adjustable rebated door frames, the recommended wall opening width is 988 mm. This dimension allows for easy installation of the door frame, ensuring adequate space for installation foam and precise levelling and alignment. An adjustable rebated door frame is a classic solution where the door leaf protrudes slightly beyond the frame when closed. It is a proven choice for functional interior doors.
Non-rebated door frame
If, on the other hand, you choose a 90 door with an adjustable non-rebated door frame, the opening in the wall should be slightly wider, at 1014 mm. Non-rebated door frames are becoming increasingly popular in modern design because when the door is closed, it flushes with the frame, creating a smooth surface. The wider opening is necessary due to the concealed hinges, which require additional installation space.
When preparing an opening for a 90 door with an adjustable door frame, always remember to leave about 1-2 cm of clearance on each side of the opening. This clearance is necessary for precise positioning of the door frame using wedges and for filling the space with assembly foam, which stabilises the door frame and provides insulation. Accurate measurements and careful execution of the opening in the wall guarantee that your 90 door with an adjustable door frame will look aesthetically pleasing and function flawlessly for many years.
