What about indoor condensed water in winter?

This is because the temperature difference between indoor and outdoor is large, the indoor humidity is high, and the thermal insulation performance of walls and roofs is poor. When the temperature difference between indoor and outdoor is large, the air near the roof is easy to form condensed water droplets in cold weather. When small water droplets gather into large water droplets, they will fall due to gravity. Treatment of condensed water:

double glass

Double glazing is used to improve the thermal insulation performance.

Drainage collection system

Design a glass roof with a certain slope and radian, and a well-organized drainage and collection system.

Strengthen indoor ventilation

To strengthen indoor ventilation, you can install an exhaust fan above the wall and turn on the exhaust regularly to increase air circulation and reduce indoor humidity.
