How to Seal Windows in Container Houses

Sealing windows in container houses requires first installing the window frame aluminum, then installing and fixing the windows, and finally ensuring proper sealing. Here are the specific steps:

I. Window Frame Aluminum Installation

The window frame aluminum serves as the foundational structure supporting the windows and must be fixed to the composite board using rivets. During installation, the window frame aluminum should be cut at a 45-degree angle to ensure tight and seamless joints. The fixing position of the window frame aluminum should be precisely determined based on the window's design dimensions. Typically, standard window dimensions are 1200 millimeters in width and 900 millimeters in height. For casement windows, additional consideration should be given to the hinge installation space. The stability of the window frame aluminum directly affects the window's wind pressure resistance, so a sufficient number of rivets should be used, with a recommended fixing point every 30-50 centimeters.

II. Window Installation and Fixing

After the window frame aluminum is installed, insert the window into the frame and adjust its position to ensure smooth opening and closing without gaps. The window should be fixed using self-drilling screws through the pre-drilled holes in the window frame aluminum. For casement windows, special attention should be paid to the hinge installation direction to ensure the opening angle meets design requirements. If the window is equipped with a security screen, it should be installed simultaneously after the window is fixed. The connection between the security screen and the window frame should use rust-proof screws to prevent rusting and detachment after long-term use.

III. Sealing Treatment

Sealing treatment is a crucial step in window sealing, directly affecting the house's rainproofing, sound insulation, and thermal insulation performance. Apply glass curtain wall waterproof sealant at the joints between the window frame and the composite board, as well as the contact surfaces between the window and the window frame. This sealant has superior weather resistance compared to ordinary sealants and can withstand long-term exposure to wind and rain. For areas prone to leakage, such as window frame corners, reinforce the sealing by cutting T-shaped sealing strips. The sealing strips should be made of ethylene propylene diene monomer rubber, which has excellent aging resistance and UV resistance, and comes with a strong adhesive backing for easy and secure installation.

IV. Inspection and Adjustment

After installation, conduct a comprehensive inspection, including checking if the window opens and closes smoothly, if the sealant is evenly applied without breaks, and if the screws are tightly secured. If any sealing issues or window deformations are found, make timely adjustments or reinstall as necessary to ensure the window functions properly and meets sealing performance standards.
