What is the heat insulation effect of the roof?

Laying heat insulation layer

The common method of top insulation is to lay insulation layer, which can effectively prevent the summer sun from shining. The commonly used materials for laying insulation layer include laying insulation bricks, painting insulation coatings on the top of the top floor, and pasting reflective tin foil. A simple thermal insulation layer is to spread a layer of soil with a thickness of about 15cm on the roof, which can play the role of thermal insulation.

Build a sunshade

In addition to laying insulation layer close to the roof, there are sun screens and awnings on the roof. The advantage of this practice is that people can have activities on the roof, such as drinking tea and chatting and enjoying the starry sky, but it is quite unreasonable and will also affect the lighting.

3. Roof planting

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 at the same time, you can eat fresh vegetables, but you should do a good job of drainage.

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.

Ceiling with thermal insulation material

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.

How to do roof insulation better? What material is good for roof insulation? Choose the top floor when buying a house, with good lighting and good view. When decorating, it was discovered that waterproof and heat insulation became a problem. For the owners of top-floor houses and self-built houses, in the hot summer, the indoor temperature soars, affecting daily life, and roof insulation becomes the most important. People who have been to tell you that there are various methods of roof insulation, and the materials are different, each with its own advantages and disadvantages. How to keep the roof warm is better, and what material is better for the roof heat preservation? Come and study!

First, how to keep the roof warm is better.

1, laying insulation layer

Air circulation can take away heat, and you can put an insulation layer on the roof. The sun shines directly on the insulation layer, and the rising temperature can be conducted away through the air between the roof and the insulation layer to prevent the top floor ceiling from rising sharply. This is a traditional and effective thermal insulation method.

Step 2 build a sunshade

In recent years, sunshade and thermal insulation have become popular because the laying of thermal insulation affects the activities of residents on the roof, and the decoration with poor quality of thermal insulation is difficult to affect the appearance.

3, laying heat insulation materials

In order to avoid the influence of tall insulating brick on the beauty of the roof and crowd activities, and avoid the influence of shading construction cost and lighting, a layer of thermal insulation material can be laid on the roof, or the combination of thermal insulation and waterproof can also be used, and the principle of air thermal insulation can also be used. This method generally uses foam materials for thermal insulation, and there are many thermal insulation materials that can be used, such as foam cement board and foam cotton. For safety, try to choose fireproof materials.

4. Greening and heat insulation

In recent years, the family greening movement has flourished, and roof insulation can also be achieved by planting vegetables and fruits. You can directly fill the roof to grow vegetables in a large area, or you can grow vegetables in containers. It is suggested to plant leafy vine crops so that vines can cover the whole roof. Planting vegetables on the roof must be based on the premise of good load-bearing on the roof, and crops cannot corrode concrete buildings.

5. Water storage and heat insulation

Water is a good heat-conducting fluid, so it can also be stored on the roof for heat insulation. The deeper the water layer, the better the heat insulation effect. If conditions permit, a rooftop swimming pool can be built to serve multiple purposes. It should be noted that if you want to use the water layer to keep warm, the quality of the roof must pass, otherwise there will be water seepage from the top ceiling over time; In addition, the water quality should also pass the customs to prevent water from corroding concrete.

6. Install light absorption and reflection devices

Light absorption or reflection devices can be installed to convert sunlight shining on the roof into electric energy or reflect it. If possible, you can install solar panels and use sunlight to generate electricity. If solar energy is not suitable, a specular reflection array can be set on the roof. Glass, thin stainless steel plate and tin foil plate are all good reflective materials.

Second, what material is good for roof insulation?

1, polystyrene board

There are two kinds of polystyrene board: foamed polystyrene board and extruded polystyrene board. The common one is expanded polystyrene board, which has average thermal insulation performance. Although it is not expensive, its strength is not good. If the roof is insulated, its working life will be short.

2. Rock wool board

The thermal insulation material composed of rock wool board and centrifugally peeled fiber cotton is generally about 30-200mm thick, with a thermal conductivity of 0.038 W/m, which has good thermal insulation effect and waterproof and flame retardant functions, but its cost performance is average, and it is mostly used in the fields of warehouses and buildings.

3. Rubber powder polystyrene particle thermal insulation slurry

The thermal insulation effect of rubber powder polystyrene particle thermal insulation slurry is also relatively general, and as a roof thermal insulation material, the requirements for construction technology are much higher than other materials, and it has the advantages of recyclable materials and environmental protection.

4. Polyurethane foam

Polyurethane foam has a variety of colors to choose from, and the material is hard and dry. Its thermal conductivity is only 0.02-0.035 watt-meter, which not only has good thermal insulation effect, but also has excellent waterproof performance. Therefore, polyurethane foam material is very suitable for roof insulation, but it is slightly expensive.

The above is Bian Xiao's knowledge about how to do a good job of roof insulation and what materials are used for roof insulation. I hope it helps you. If you want to know more about roof insulation, please continue to pay attention.
