How do I prevent water from getting into gaps between aluminum profiles during installation?

To prevent water from getting into gaps between aluminum profiles during installation, use high-quality sealants and gaskets. Ensure proper alignment and fit of the profiles to minimize gaps. Install weep holes to allow water to drain out. Apply a water-resistant membrane or flashing behind the profiles. Regularly inspect and maintain the installation to identify and fix any issues promptly. Proper installation techniques and materials selection are crucial to prevent water infiltration.
