What is the name of the pressure bag installed to temporarily fix the door and window frames?

1. Now the auxiliary frame is basically installed, because installing the auxiliary frame is beneficial to the installation firmness, finished product protection, thermal insulation effect and installation accuracy of the window. In the newly-built building, because the size of the hole of doors and windows is not very standard after completion, the processing size of doors and windows can be measured more accurately after installing the auxiliary frame.

2, make up the gap between the door and window profiles and the wall, which is beneficial to waterproofing; Enhance the flatness of doors and windows in horizontal and vertical directions; So that the surfaces of doors and windows are not damaged or scratched, and the doors and windows are protected.

3. The door window frame is a frame fixed on the wall and used for installing doors and windows. According to the fixing method of door and window frames, it can be divided into vertical opening and plug opening.

4, it is also conducive to the installation of doors and windows, and the operability is better. It is more conducive to the thermal insulation and sealing performance of doors and windows, especially the thermal expansion and cold contraction of plastic steel doors and windows due to thermal expansion and cold contraction. Thus, the edges of doors and windows are cracked, which not only affects the overall beauty, but also reduces the functional requirements of seepage prevention, energy saving and compression deformation.

Objectively speaking, the auxiliary frame is not necessarily conducive to the sealing, heat preservation and heat insulation of doors and windows, especially the steel auxiliary frame has stronger thermal conductivity. If it is not handled properly, it will easily lead to leakage and heat conduction.
