Can the roof insulation cotton really keep warm? As we all know, this season is the hottest summer. When the weather is hot, the roof will absorb heat easily. I believe that everyone will feel uncomfortable living in a stuffy room. So can the roof insulation cotton really keep warm?

Can the thermal insulation cotton on the roof really insulate heat? 1 It means that this kind of thermal insulation cotton is really different from what you think. If used well, it can be insulated. If it is not used well, it is an IQ tax. There are two things you see most often:

The back won't stick.

This kind of thermal insulation cotton is usually bought and pasted directly on the roof. In fact, the effect of pasting it on the cement floor is very poor. Even after the floor is cleaned, it is still not firmly adhered, and finally it can only be held down with bricks, so it is not that the roof is not a smooth floor, but it should be carefully selected.

Sponge absorbs water

Some netizens complained that it rained the night before and it was sunny the next morning, but the eaves were still dripping. When I went up to check, I found that the thermal insulation cotton did not absorb water and accumulated water. If it is not dried, it will become moldy and black after a long time. Can it be said that it is taken back in rainy days and spread out in sunny days?

If it is to be installed, it is suggested that several layers of aluminum foil adhesive must be attached to the seam of thermal insulation cotton, so as to reduce the influence of water absorption on the back adhesion. Generally speaking, thermal insulation cotton can really cool down, but the premise is to find out whether the roof of the house is smooth or not, otherwise it will fall off soon after you buy it.

In fact, there are many ways to insulate the top floor. If you are in trouble, you can choose to hang a sunscreen. The effect is good and simple. Compared with thermal insulation cotton, it can save money and has a wide range of applications. You can put it away after summer and use it next year.

If you want to have a good effect, you can also lay insulating porcelain plates, which used to be common abroad and also in China. It is no problem to reduce the temperature of 20℃, and the ventilation at the bottom is increased, which not only keeps the temperature and cools the top floor, but also protects the top floor. It will not affect the use of the top floor, and there is no problem in daily walking and drying. Compared with thermal insulation cotton, the face value is also better.

The bottom of the whole porcelain plate is about 10 cm overhead. Usually when it rains, water can flow down the gap and then be discharged through the water pipe, so there is no water accumulation problem.

It should be noted that after laying the insulating porcelain board, the whole ground will rise more than ten centimeters, which will lead to the height contraction of the fence, so it is best to measure the height of the fence on the top floor of your house before laying it.

Living on the top floor is really hot in summer. In addition to the insulation layer made during decoration, you can also choose other insulation measures to reduce the indoor temperature, that is, save electricity.

Can the roof insulation cotton really insulate heat? Must be valid.

Is the insulation on the top floor useful?

Useful. The insulation layer on the top floor can effectively prevent the summer sun from shining. When the sun shines directly on the insulation layer, the rising temperature will be conducted out through the air between the roof and the insulation layer, thus indirectly cooling the roof.

Commonly used materials for laying insulation layer include laying insulation bricks, painting insulation coating on the top layer, and pasting reflective material tin foil. The simplest insulation layer with relatively little investment is to lay a layer of soil with a thickness of about 15cm on the roof. These methods can play a role in heat preservation.

What are the methods to keep the top floor warm?

Besides laying insulation layer, there are many ways to insulate the top floor. Here are some examples:

1, building sunshade

In addition to laying thermal insulation layer close to the roof, there are sunshade nets and umbrellas on the roof. The advantage of this method is that people can have activities on the roof, such as drinking tea and chatting and enjoying the starry sky, but the investment is relatively large and the construction is unreasonable, which will also affect the lighting.

2. Shading by green plants

There are many ways to grow vegetables and fruits on the roof, which can be planted directly on the soil, and there are also combined racks, that is, buy ready-made vegetable planting boxes, build simple vegetable racks, and plant some climbing vines or vegetables. These methods can also play the role of heat preservation, and you can eat fresh vegetables at the same time, but you should do a good job of drainage.

3. Water storage and heat insulation

Building a swimming pool on the roof and injecting water about 20 cm high into the pool can also play a role in heat insulation. If the roof has a strong load-bearing function, a swimming pool can also be built, but this method needs to do a good job of waterproofing the roof.

4, ceiling and thermal insulation materials

Roof insulation is imported as external insulation, and indoor insulation can also be considered, such as making a ceiling, adding insulation board or insulation cotton in the ceiling, which can not only ventilate but also keep warm.

5. Close the south window and close the curtains.

In addition to making an issue on the roof, you should also pay attention to it at ordinary times. Close the south window, open the north window and pull the curtain of the south window in hot weather. These daily small moves can also reduce the temperature in the house a lot.

Can the roof insulation cotton really insulate heat? 3. The method of roof insulation

① Install a black sunscreen on the roof: Installing a black sunscreen on the top floor can play a very good role. I believe many people have also seen this kind of black sunshade net. Whether it is installed on the roof, in front of the building or on the roof of the carport, it can effectively block the sun and make the temperature under the sunshade net drop obviously. This method is super suitable for self-built roof and self-built facade insulation. In summer, many people use it as a sunshade in front of the main entrance.

② Installing color steel tile on the roof: Compared with the trouble of installing black sunshade every year, it is most convenient to install a layer of color steel tile directly on the roof. Because after the installation of the color steel tile, a protective layer of heat insulation and cold preservation is actually formed on the roof, and there is space under the color steel tile for ventilation and heat dissipation, so that the top floor is not so hot indoors in summer. This form of roof insulation is most used in self-built houses, and the effect is also the most obvious.

③ Roof insulation layer: there is a kind of insulation brick, which is used for roof insulation. This is used on the roof of a self-built house to form an insulation layer, which can also directly and effectively block the sun and make the top floor less hot.

(4) Growing vegetables on the roof of a self-built house: In fact, the effect of growing vegetables on the top floor is very similar to that of a garden, but it is different on the soil layer. To grow vegetables on the top floor, you need to use the soil layer. At this time, the top floor is protected by soil layer, which directly plays the role of heat insulation. If you are making grapes and other fruits, you can further play a role in heat insulation.

⑤ Making ceramsite concrete insulation layer on the roof: ceramsite has waterproof, moisture-proof and thermal insulation functions, so it is directly used to make concrete layer on the roof, which firstly ensures light weight and secondly has good thermal insulation effect. Many self-built houses take this into account when they are built, and directly make such insulation methods.

⑥ Use outdoor anticorrosive wood flooring: If you have certain quality of life requirements, you can create a good living environment even if you build your own house. At this time, it is a good way to use anticorrosive wood floors to keep the roof warm. The anticorrosive wooden floor is very similar to the electrostatic floor in the indoor computer room. There will be high floors when paving, so that ventilation can be realized. Then through the performance of anticorrosive wood, there will be two layers of heat insulation, and the aesthetic degree is still very good.
