Is the top floor too hot in summer? Owners don't have to worry, pulling a thin layer of black net is too effective for heat insulation and cooling.

Nowadays, many people know that the top floor is hot in summer, so they should pay attention to heat insulation and cooling when buying the top floor. Many owners will choose to lay insulation layer on the roof, and now it is more popular to pull a thin layer of black net. Is the top floor too hot in summer? Owners don't have to worry, pulling a thin layer of black net is too effective for heat insulation and cooling. In view of these problems, I will give you a detailed introduction below.

1. What if the roof is too hot?

Many netizens suggested laying a black sunscreen screen on the top floor. They thought they could just buy it and put it on the top floor, but they learned that laying a sunshade net is also exquisite. There are overhead shops and those directly laid on the roof. What's the difference between them?

In fact, most of them are suspended, so that there can be air circulation at the bottom to take away all the residual heat, and the heat insulation effect is very good. Laying directly on the ground is not only bad for sun protection, but will get hotter and hotter, because the black sun screen will absorb heat and be laid directly on the roof floor. There is no heat dissipation space in the middle, which will directly conduct heat to the roof, and the effect will be counterproductive!

So how high should the sun screen be hung? As the case may be, if no one walks on the roof at ordinary times, the sunshade net is about 1m from the ground, but if someone is drying clothes or growing vegetables on the roof at ordinary times, it is best to choose about 2m, so as not to hinder everyone from walking on it. Note, however, that since it is a roof, the sunshade should not be too high. In addition, in windy weather, it is best to reinforce it to prevent scratches.

In fact, the main function of laying sunscreen on the roof is sun protection and heat insulation. If you want to insulate the ground, the most common method is to lay the insulation layer, such as laying insulating brick, painting the roof with insulation paint, or even laying reflective tin foil (be careful not to affect other owners, or you may be complained). Another way with the lowest cost is to spread soil on the top floor and then plant some green plants or vegetables, which can play a role in heat insulation.

The top floor is insulated, and there is a fresh insulation method, that is, storing water and raising fish on the top floor, which can really cool down. If you want to learn, you must do a good job of waterproof and load-bearing, otherwise it will be annoying if there are problems in the later stage, and it will cost a lot of money to change!

Many owners grow vegetables and flowers on the roofs. If they are worried about the summer sun, they will choose to hang a sun screen to prevent insects, cool down and moisturize. The cost is not high, and it can be collected and recycled later. It's convenient, and it's also suitable on the balcony!

Second, who will bear the cost of repairing the top floor leakage?

1. For commercial housing, the warranty period of roof waterproof layer is 5 years. Therefore, if the top floor of the shopping industry leaks water during the waterproof warranty period, it is the responsibility of the developer.

2. If the roof leaks due to man-made damage, you can only find the damage provider to provide maintenance services, or the property provides maintenance, so that the damage provider can bear the maintenance costs. Specific maintenance services and costs can be decided through consultation with the damage provider. If the other party refuses to compensate for the loss, it will take judicial channels.

3. If the roof leaks after the warranty period, the developer has nothing to worry about. Since the roof is shared by the public, it is the responsibility of all owners.

4. If the property right belongs to the welfare house of the unit and the self-built house leaks, find the logistics department of the unit or the department responsible for housing management and welfare, and apply for maintenance.

If it is a rented house, the maintenance of roof leakage is entirely the responsibility of the landlord. Therefore, we should contact the landlord in time and urge the other party to complete the maintenance as soon as possible.

Third, how to do the thermal insulation measures on the top floor?

1. air insulation

Not really high-tech. In fact, installing a 30 cm hollow compartment on the roof is actually equivalent to adding a hat to the exposed roof. The heat of sunlight will only be directly transmitted to the carriage, and the air in the middle effectively isolates the direct transmission of heat.

2. Tin foil insulation

This heat insulation method is one of the commonly used methods at present, and it is usually directly covered on the surface of leak-proof asphalt or other materials. Because the material is tin foil with strong reflective performance, it can reflect sunlight and reduce the absorption of sunlight heat by the floor.

3. Water insulation

This kind of application is less, water is injected into the overhead floor of the roof, and heat is dissipated by absorbing the heat of water. However, this method requires high waterproofing of the roof. If the waterproof layer is not done well, it will become stealing chickens and not eating rice.

4. Ceramsite concrete insulation layer

Of course, ceramsite concrete can also be laid on the top floor, which can also effectively insulate the heat and greatly reduce the indoor temperature.

5. Soil insulation (planting green plants)

This method is common in roof gardens and vegetable gardens, killing two birds with one stone, but it is the best choice for owners who want to have their own secret gardens between busy cities.

If you want to lay insulation on the top floor, you should pay attention. Choosing the right material, sunscreen can not only play the role of heat insulation and cooling, but also has a relatively low cost. For the owners of the top floor, they should pay attention to proper sun protection, especially in summer. They can plant some green plants on the top floor or use other heat insulation materials.
