What are the two installation methods of door and window frames?

A, door window frame installation method:

1. Vertical port

Vertical installation, also known as vertical installation, refers to the way that the window frames are fixed together when the wall is built, and the sash is directly installed after the wall is completed.

This way is more traditional. The window treated in this way has better air tightness and is not easy to fall off.

2. Plug

Plug-in, also known as plug-in, refers to a way of measuring the size in advance, leaving the openings of doors and windows, and installing the door and window frames after the wall construction is completed.

This method does not delay the construction period. When all the bricklayers are finished, the carpenter can directly enter the site to seal the window when decorating. It only needs to measure the size in advance, which requires higher technological requirements and dimensional errors.

Second, the door window frame installation matters needing attention:

1, the installation should be horizontal and vertical, the outline and wall thickness of doors and windows should meet the design requirements, and the accessories used should be made of stainless steel or galvanized materials.

2. During installation, attention should be paid to the tightness between the window and the wall. If plug-in installation is adopted, there will be a gap between the hole and the wall due to dimensional error. The filler must be elastic material, and the surface is sealed with sealant.

3. The gap between the door and window frame cannot be filled with cement mortar, otherwise it will easily crack again in the later period because of thermal expansion and contraction.

4. The door window frame must be installed firmly, the sash should be opened flexibly and closed tightly, and it is not allowed to tilt or slide.

5. The number, location, embedding method and connection mode of embedded parts of door and window frames must meet the design requirements. It is forbidden to use nails to fix doors and windows on masonry. The opening direction, installation position and connection mode of door and window frames should meet the design requirements.

6. When buying doors and windows, you must go to the formal building materials market and choose high-quality materials. Don't be tempted by low prices, especially some inferior plastic doors and windows. The quality of lining steel is poor, even without lining steel, and other accessories are also poor.
