What are the consequences of improper vent construction?

1. Waterproof failure
The membrane is not tightly spliced, not firmly fixed or damaged, resulting in moisture infiltration, which cannot achieve the expected waterproof effect, causing dampness and mold inside the building, and damaging the decoration and equipment.
2. Impaired ventilation function
During construction, the membrane is overstretched, wrinkled or blocked, affecting the normal exchange of gas, which may cause moisture accumulation inside the building structure, increase the risk of condensation, and damage the performance of the insulation material.
3. Reduced insulation effect
Due to vent construction problems, moisture enters the insulation layer, reducing its insulation performance and increasing energy consumption.
4. Structural damage
Long-term moisture accumulation may cause corrosion of metal structures and decay of wood, thereby affecting the stability and safety of the building structure.
5. Mold breeding
The internal humid environment provides growth conditions for mold, affecting indoor air quality and causing harm to human health.
6. Increased maintenance costs
Improper construction in the early stage may require maintenance and rectification in the later stage, adding additional costs and manpower investment.
7. Shortened building service life
A series of problems may shorten the service life of the entire building.
