How to Install Doors and Windows in Container Houses

When installing doors and windows in container houses, it is necessary to select the installation method according to the type of doors and windows, and pay attention to size matching, firm fixation, and sealing treatment, as follows:

I. Door and Window Types and Size Selection Doors and windows for container houses are divided into two categories: standard sizes and custom sizes.

• Doors: The standard single-door size is 800 millimeters wide and 2000 millimeters high, suitable for daily entry and exit; the double-door size is 1600 millimeters wide and 2000 millimeters high, facilitating the handling of large items; custom-made doors can be sized according to specific needs.
• Windows: The standard window size is 1200 millimeters wide and 900 millimeters high, providing ample natural light; casement windows feature an aluminum alloy tempered coated hollow structure, offering both insulation and sealing properties. Selection Recommendations: For residential purposes, prioritize large windows to enhance lighting and ventilation; for warehouse-type uses, double doors are recommended; windows should be paired with security bars or safety glass to improve safety.

II. Installation Methods and Steps

1. Embedding and Positioning

   • Before installation, ensure that the container walls are level and mark the installation positions on the walls according to the door and window sizes.
   • For roller shutter doors, reserve space for motor installation and track slots; for casement windows, reserve 45-degree angle fixing positions for the window frame aluminum.

2. Fixing Door and Window Frames

   • Insertion Installation Method (commonly used): First, construct the walls and reserve openings for doors and windows. Place the door and window frames into the openings, adjust their horizontal and vertical levels, and secure them with fastening screws or rivets. For example, when installing windows in packing-box units, fix the window frame aluminum at a 45-degree angle on the composite board, and then secure the windows to the frame aluminum with self-drilling screws.
   • Upright Installation Method (special scenarios): First, erect the door and window frames and then construct the walls. This method is suitable for scenarios where construction needs to be synchronized with the walls, but it is rarely used in container houses.

3. Installing Door and Window Sashes

   • When installing door sashes, ensure that the hinges are firmly fixed; for double doors, adjust the alignment of the two sashes; for roller shutter doors, install the motor and debug the lifting function.
   • After installing window sashes, check their opening and closing flexibility; for casement windows, confirm that the sealing strips are tightly fitted.

III. Key Considerations

• Sealing Treatment: Fill the joints between doors, windows, and walls with sealant to prevent rainwater leakage; regularly clean the tracks of roller shutter doors to remove leaves and debris and avoid jamming.
• Rust and Corrosion Prevention: After cutting or welding door and window frames, sand them down and apply epoxy primer and topcoat; in coastal areas, shorten the recoating cycle to 3-5 years.
• Safety Reinforcement: For container houses used outdoors for long periods, install steel frames or concrete piers around the doors and windows to enhance wind and earthquake resistance.
