Generally speaking, the maintenance cost of a hidden frame curtain wall is relatively high,The high maintenance cost of a hidden frame curtain wall is mainly reflected in the following aspects:

1. Difficulty in replacing glass

The glass of a hidden frame curtain wall is connected to the sub-frame through structural adhesive. When replacing the glass, the structural adhesive needs to be removed very carefully, which is complicated and requires high technical requirements.

If a piece of glass is damaged, professionals need to use special tools and techniques to remove and replace it, which increases labor costs.

2. Aging monitoring of structural adhesive

The performance of structural adhesive is crucial to the safety of hidden frame curtain walls and needs to be tested and evaluated regularly.

Detecting whether the structural adhesive is aging or failing requires professional equipment and technology, which also increases the cost of maintenance.

3. Difficulty in inspecting internal components

Because the frame is hidden inside, it is difficult to directly observe the condition of the internal components.

In order to check whether the internal connectors, supports, etc. are normal, it may be necessary to use special testing equipment or dismantle part of the curtain wall, which increases the complexity and cost of maintenance.

The maintenance cost of the exposed frame curtain wall is relatively low for the following reasons:

1. Glass replacement is relatively simple

The glass of the exposed frame curtain wall is installed in a clearly visible frame, and there is a large operating space when replacing the glass, which is relatively easy.

Ordinary workers can perform replacement after a certain amount of training, and the labor cost is low.

2. The frame is easy to inspect and maintain

The frame is exposed to the outside, and its surface condition, such as corrosion, deformation, etc., can be intuitively seen, which is convenient for timely detection and treatment of problems.

However, the specific maintenance cost will also be affected by factors such as the quality of the curtain wall, the use environment, and the maintenance frequency.

In industrial areas with severe pollution, the frame of the exposed frame curtain wall may be corroded faster, thereby increasing the maintenance cost. The hidden frame curtain wall uses high-quality and durable structural adhesives and is in a milder environment, so its maintenance cost may not be as high as expected.
