How to insulate the tin factory?

There are four insulation methods in ironmaking workshop:

1. Thermal insulation cotton is added to the roof of the iron house workshop to reduce the heat from the sun outside the workshop to the roof and into the workshop.

2. Cover the roof of the iron house workshop with a heat insulation sunshade net to prevent the direct sunlight from entering the workshop and causing high temperature.

3. Install a sprinkler system on the iron roof to absorb the heat of the sun through circulating water and reduce the direct heat of the sun from entering the factory building.

4. Install ventilation balls on the roof to discharge the heat in the factory building, so as to reduce the speed and quantity of direct sunlight from the roof pouring into the factory building and improve the air circulation speed in the factory building.
