Comparison of advantages and disadvantages between unit glass curtain wall and frame glass curtain wall

The unit glass curtain wall is a combination of aluminum alloy frame, glass, spacer, insulation material, shock absorption and waterproof material and decorative fabrics in the factory into a curtain wall unit with additional iron parts, which is transported to the construction by a special transport vehicle. After the scene, the fascia is assembled on the site, and the glass curtain wall that is directly connected to the building structure. The frame type glass curtain wall is to transport the finished components in the workshop to the construction site, and install the components on the building structure one by one according to the construction process, and finally complete the curtain wall installation.

Comparison of the advantages of unit glass curtain wall and framed glass curtain wall:

Advantages of a unitized glass curtain wall:

1 The quality of the curtain wall is easy to control.

2 On-site construction is simple, fast and well managed.

3 can accommodate larger structural displacements.

4 waterproof performance is better.

5 is relatively easy to achieve high performance curtain wall requirements.

6 is usually able to adapt to the needs of modern building development.

Advantages of framed glass curtain wall:

1 is easier to design and flexible to install.

2 materials are easier to store at the site.

3 easy to repair.

4 The cost is generally lower than the unitized curtain wall.

Comparison of the disadvantages of the unitized glass curtain wall and the framed glass curtain wall:

Disadvantages of the unit glass curtain wall:

1 If the installed unit block needs to be repaired or replaced, it may be difficult.

2 The structural form determines that the aluminum profile of the unit curtain wall is used at a higher cost, and the cost is generally higher than that of the frame type curtain wall using the same material.

Disadvantages of framed glass curtain wall:

1 The quality and performance of the curtain wall installation is difficult to guarantee.

2 requires a lot of on-site management and quality control work.

3 is easier to seep.

4 The structural displacement that can be accommodated is very limited.

5 The construction period of the site is long.

6 A large number of assembly components are easily lost and damaged when stored on the floor.

7 curtain wall installation quality and performance is difficult to guarantee.
