Container House Air Leakage

Air leakage in container houses may be caused by loose fasteners, material aging, structural deformation, design flaws, or improper installation, requiring targeted inspection and repair.

1. Loose or Aged Fasteners

During the installation or use of container houses, if the roof is stepped on or subjected to external impact, fasteners (such as bolts and rivets) may become loose. Meanwhile, if the waterproof gaskets of fasteners are exposed to harsh environments for a long time, they may lose their sealing properties due to aging, leading to air leakage. Regularly inspect the condition of fasteners, promptly tighten loose components, and replace aged waterproof gaskets.

2. Material or Construction Defects

If the waterproof materials selected for container houses are substandard or the seams and holes (such as those around fans and exhaust pipes) are not properly treated during construction, it may result in poor sealing. Additionally, material aging (such as cracking of sealants) can also reduce wind resistance. Select waterproof materials that meet standards, strictly seal seams during construction, and regularly inspect the condition of materials, promptly repairing any cracks.

3. Structural Deformation or Damage

Under the action of wind loads, snow loads, or thermal expansion and contraction, container houses may experience panel deformation, causing cracks at the joints to expand and damaging the original sealing. For example, extreme weather conditions (such as 8-level winds) may damage the unreinforced structure of the house, leading to air leakage. Enhance the structural stability of the house, such as adding wind-resistant cables, reinforcing beams and columns, or increasing the density of self-tapping screws, and regularly inspect the panels for deformation.

4. Design Flaws

If the gutter of a container house has no horizontal slope or the outlet design is unreasonable, it may cause water to back up into the eaves gutter, indirectly leading to air leakage. Additionally, if the house does not have sufficient safety distance or the ventilation design is improper, it may also exacerbate the air leakage problem. Optimize the design of the drainage system to ensure a reasonable gutter slope and unobstructed outlets, and plan the house spacing and ventilation structure reasonably.

5. Improper Installation or Maintenance

If the installation of a container house is not carried out according to specifications (such as not conducting a water spray test to verify waterproof performance) or if there is insufficient maintenance later (such as not promptly cleaning fallen leaves from the roof or not replacing aged sealants), it may lead to air leakage. Strictly follow installation specifications, conduct a water spray test before delivery, and regularly clean the roof and replace sealants (replace every 5-7 years).
