Container House Airtightness
The airtightness of container houses is influenced by three factors: the precision of panel processing, the performance of sealing materials, and construction techniques.
Panel processing precision directly affects the foundation of airtightness. The body of a container house is assembled from multiple panels, and differences in the cutting precision and bending angles of these panels can lead to gaps at the joints. For example, if the gap between the door frame and the body exceeds 2 millimeters, dust can directly infiltrate indoors during sandy weather. Professional suppliers use CNC bending machines to control the bending angle of the door frame within plus or minus 0.5 degrees, ensuring tight fitting at the joints and thereby reducing air and dust infiltration.
The performance of sealing materials is a key guarantee for airtightness. The joints between the door frame and the body require weather-resistant sealing strips, such as ethylene propylene diene monomer (EPDM) rubber sealing strips, which have better weather resistance than ordinary silicone strips and can last for more than 5 years. These sealing strips can effectively resist the effects of ultraviolet rays, ozone, and extreme temperatures, maintaining elasticity over the long term and preventing sealing failure due to material aging.
Construction technique level determines the final effect of airtightness. When purchasing, you can judge the level of craftsmanship by observing the uniformity of glue application at the joints between the door frame and the body: uniform and continuous glue strips indicate mechanized construction rather than manual touch-ups. Mechanized construction ensures consistent thickness and width of the sealant application, forming a complete sealing barrier and avoiding local leakage caused by manual operation errors. Additionally, using structural waterproofing design on the roof can also enhance the airtightness of the house, preventing rainwater from infiltrating indoors through roof gaps.
The airtightness of container houses must be comprehensively controlled from the aspects of panel processing, sealing materials, and construction techniques to ensure their performance under different climatic conditions.
