How to keep the ceiling under the glass house in the sun room warm?

First, the outermost layer should be mainly reflective, which can be solved by coating. The second is to use thermal insulation materials to prevent external heat from entering the room.

You don't need to make colored steel plates. If the heat brought by the glass roof is not particularly severe, you can directly open a skylight to solve it within your tolerance. The skylight was opened at the top, and all the hot air was released. The timely air circulation in the sun room played a cooling effect. Everyone knows this truth, so I won't go into details here. As for whether to install semi-automatic sunroof or electric sunroof, it depends on your own needs.

If it is the heat that cannot be solved by opening the skylight, it is recommended to configure the skylight sunshade product. This is also easy to understand, that is, the heat is blocked out by shading products. Because heat can't enter the sun room, there is no problem of temperature rise in the sun room.

There are many sunshade products in the sun room: scroll type, folding type, blade turnover type and so on. Some people want to say that I installed a glass roof just to see the scenery. I usually watch the night sky at night. You cover the top with a sunshade. What do I think? This problem is easy to solve. At present, the sun room has sunshade products, which can shade the sun but can't cover the scenery. If there is such a demand, you can choose a sunshade product that does not cover the scenery.

Another way is to spray water to cool down. There is a saying that an iron plate has 10000 cooling methods, so it is better to pour a ladle of water to save trouble. Water spraying on the glass roof of the sun room can also be explained by this sentence. Using low-temperature water to take away the heat from the sun room can cool down and clean the top glass at the same time, which really kills two birds with one stone.

Extended data: thermal insulation

Thermal insulation refers to the physical process that when heat is transferred from a high-temperature space to a low-temperature space, the temperature change per unit space becomes smaller due to the change of conductive medium, thus blocking heat conduction.

Thermal insulation materials are usually used to achieve thermal insulation, and some dynamic technical means such as aerodynamics are used to achieve thermal insulation.

Basic requirements of thermal insulation materials

The basic requirements of thermal insulation materials are: the thermal conductivity should not be greater than 0.17w/(m k), the apparent density should be less than 1000kg/m3, and the compressive strength should be greater than 0.3MPa. When selecting, the purpose of the building, the structure of the envelope, the difficulty of construction, the source of materials and economic accounting should be comprehensively considered.

Classification of thermal insulation materials

There are many kinds of insulation materials, which can be divided into three categories: inorganic insulation materials, organic insulation materials and metal insulation materials. According to the morphological classification, it can be divided into fibrous, microporous, vesicular and layered.
