What should I do to insulate the attic? In addition, when burying the circuit, we must consider it comprehensively, such as reserving air conditioning lines, because the transformation of the attic will be more troublesome. In addition, because the attic roof is inclined, it is also important to make good use of space. For example, in the triangle area where the wall meets the floor, open shelves can be placed to make room for storage.
1. Laying thermal insulation layer
Air circulation can take away heat. So you can put a layer of insulation on the roof, and the sun shines directly on the insulation. The rising temperature can be conducted through the air between the roof and the insulation layer to prevent the ceiling on the top floor from rising sharply. This is a traditional and effective thermal insulation method. The figure below shows the traditional thermal insulation layer, which can be laid with pre-paid concrete or emerging materials in insulating brick. Non-refractory materials are not recommended, otherwise the fire will get out of control in summer.
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.
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 heat insulation material can be laid on the roof (which can also be both heat insulation and waterproof), and the principle of air heat insulation can also be used. This method generally uses foam materials for heat insulation. There are many kinds of thermal insulation materials that can be used, such as foam cement board and foam cotton. For safety, try to choose fireproof materials.
Second, the roof 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, you can also build a rooftop swimming pool, which can be used for 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 the test, otherwise there will be water seepage in the ceiling of the top floor after a long time; In addition, the water quality should also pass the customs to prevent water from corroding concrete.
Third, planting green plants for heat insulation.
Roof insulation can be achieved by growing vegetables and fruits at home. 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.
Fourth, install heat absorption or 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.
