The present invention relates to a door frame assembly, and more specifically, to a door frame assembly used to install windows, such as doors or windows, in openings of a building.

Doors are installed in buildings to allow people to enter and exit, and windows are installed for ventilation and lighting. For this purpose, an opening is formed in the wall of the building during the construction process, a door frame is constructed in the opening, and then windows such as doors or windows are installed in the door frame.

The openings of a building appear to be exactly horizontal/vertical to the naked eye, but there are subtle differences in the top, bottom, left, and right spacing, so it is common for the horizontal/vertical alignment to not be exactly right. If the door frame and window are installed without the horizontal/vertical alignment of the opening accurately, distortion may occur in the door frame, and as the casement window rotates, it may interfere with the door frame and cause a malfunction.

Therefore, when installing a roof in an opening in various construction sites and construction environments, use construction wood or other construction materials (urethane foam) to adjust the spacing between the top, bottom, left, and right of the opening to fill the empty space equal to the gap and level it accurately. /Work to align the vertical. In addition, even after installing a window in the opening, the exposed structure is finished by adding molding or applying silicone as a finishing material to cover the exposed structure.

However, when adding molding, there is the inconvenience of having to prepare molding material (MDF, wood, etc.) to the length of the opening and carrying equipment or tools to fix it to the construction wood. When finishing by applying silicone, the amount of silicone must be controlled and applied evenly with a certain amount of force. However, depending on the skill level of the worker, the work results may be inconsistent, which may result in differences in finishing quality. Additionally, the silicone used for finishing has the disadvantage of changing color over time.
