Is it better to insulate the roof inside or outside?

Of course, the external insulation is good, the internal insulation is good, you can't nail things on the wall, you can't hang it! Now new houses generally do exterior wall insulation Interior wall insulation is rarely done, exterior wall insulation form Single material insulation exterior wall: aerated concrete, sintered insulation brick composite insulation exterior wall:

According to the different positions of insulation materials, it can be divided into internal insulation, external insulation and sandwich insulation exterior walls. Thermal insulation and decoration integrated board.

Others: Thermal insulation blocks, etc. Exterior wall insulation technology Interior wall insulation is to place the insulation material on the inside of the exterior wall. Pros:

1) The requirements for the technical indicators such as waterproofing and weather resistance of the veneer and insulation materials are not very high, and the gypsum board and gypsum plastering mortar can meet the requirements of use, and the materials are convenient; 2) The internal insulation material is separated by the floor slab, and the construction is only within the range of one floor height, and no scaffolding is required.

3) In areas with hot summer and cold winter and hot summer and warm winter, the internal insulation can meet the requirements; 4) For the energy-saving renovation of existing buildings, especially when the house is sold to an individual, it is difficult to transform the whole building or the whole community in a unified manner, only the possibility of using internal insulation is greater. Therefore, in recent years, external wall insulation has also been widely used. Cons:

1) Due to the ring beam.

Floor slabs, structural columns.

etc. will cause thermal bridges, and the heat loss is large; 2) Due to material, structure, construction and other reasons, the finishing layer is cracked; 3) It is not convenient for users to decorate and hang ornaments twice; 4) occupy indoor space; 5) When the existing buildings are renovated for energy saving, it will interfere greatly with the daily life of residents. 6) The wall is greatly affected by the outdoor climate, and the temperature difference between day and night and winter and summer is large, which is easy to cause cracking of the wall. Exterior wall sandwich insulation technology Exterior wall sandwich insulation is to place the insulation material between the inner and outer wall pieces of the exterior wall, and the inner and outer wall pieces can be made of concrete hollow blocks.

Advantages: 1) It forms an effective protection for the inner wall pieces and insulation materials, and does not have high requirements for the selection of insulation materials, polystyrene.

Glass wool and urea-formaldehyde on-site casting materials can be used; 2) The requirements for the construction season and construction conditions are not very high, and do not affect the winter construction. It has been used in Heilongjiang, Inner Mongolia, northern Gansu and other cold areas. Cons:

1) In non-severe cold areas, this type of wall is still thicker than traditional wall; 2) There needs to be connectors between the inner and outer wall pieces, and the structure is more complex than that of traditional walls; 3) There are many "thermal bridges" in the outer envelope structure. In the ** area, the setting of ring beams and structural columns in the building, there are more "thermal bridges", and the efficiency of insulation materials is still not fully played. 4) The outer wall is greatly affected by the outdoor climate, and the temperature difference between day and night and winter and summer is large, which is easy to cause wall cracking and rainwater leakage.

4.Insulated blocks.

The roof insulation should be done on the outside to work well. Now a large number of houses are being renovated for energy conservation and adding insulation layer construction, and the insulation layer is built outside. It can directly play the role of full coverage, and the inner layer is also affected by the insulation layer and is not affected by the outdoor environment.

If it is done inside, condensation will also be generated between the outer layer and the insulation layer, and the interior decoration may also destroy the insulation layer, so the insulation layer should be made outside.

Hello, I think it's better to keep the top floor insulated outside, because it's to make it resist the cold weather outside, and the effect should be better when you do it, thank you!

Of course, it should be done outside, so that it will not reduce the space in the house, and the effect is relatively good.

First, it is necessary for the state to increase the energy-saving standard of civil buildings to 50%, that is, if the top floor is insulated, the energy consumption of the users on the top floor will be reduced a lot in winter, so it is necessary to do thermal insulation treatment.

Second, the specific construction method:

First of all, the top of the concrete cast-in-place slab is cleaned to remove dust and other impurities.

Then do the waterproof coating, because the waterproof coating itself is relatively thin, less than 1 mm, so it can be ignored. Then make a layer of expanded perlite insulation material on it, the thickness must be controlled within centimeters, if it is too thin, the insulation effect is not ideal.

Finally, make another 1 cm of mortar leveling on top of the perlite. Because the perlite insulation material has good adhesion to cement mortar, there will be no peeling in winter. If it is made of polystyrene board, due to the severe cold and dryness in winter, the polystyrene board and cement mortar will peel, which will destroy the thermal insulation effect.

Due to the good adhesion of perlite and cement mortar, a whole is formed, and the insulation and surface strength meet the requirements.

It is recommended to do it, because for friends who live on the top floor, there will be such a feeling every summer, that is, the indoor is particularly hot, and it feels several degrees higher than other floors. In winter, it's especially cold indoors. Moreover, as one of the most important parts of the building, the most important function of the roof is waterproofing and thermal insulation (heat insulation), which is not only related to the creation of real estate brand products, but also related to the life of the building, and represents everyone's beautiful hope for the home.

The integrated system of ceramic sheet waterproof and thermal insulation combines high-quality waterproof and thermal insulation materials into integrated boards through special processes, plus construction, and solves the historical problems that plague the industry with roof waterproofing and thermal insulation in one stop. At the same time, the structural level is simplified, the construction is more convenient, the construction period is shorter, and the comprehensive cost is lower.

Kiss! Hello, happy to answer your <>

Which insulation effect is better, the external insulation or the internal insulation of the roof is as follows: of course, the external insulation is good. Advantages of internal insulation:

The cost is low and the construction is simple. Disadvantages: poor insulation effect (because it is not a full-coverage insulation layer), condensation will occur (because the wall is cold, the insulation layer is a hot wheel, and the temperature difference between inside and outside forms condensation), affecting the decoration (the insulation layer is inside, and the decoration of the wall will destroy the insulation layer during decoration), and affecting the area of the set (the problem of calculation rules for the construction area).

Advantages of external insulation: good thermal insulation effect, does not occupy indoor space, is it useful to do internal insulation on the top floor? Useful.

The top floor can be used for thermal insulation indoors. Generally, new buildings, the state is required to do energy-saving thermal insulation, otherwise it is impossible to accept, from the architectural drawings design review stage there are energy-saving thermal insulation design. Therefore, there is an external insulation layer on the roof of the top floor.

Basically, houses after 2005 have thermal insulation requirements. If it is an old house from the 70-80s, the insulation on the top floor is not so good. It can be used for internal insulation.

It is best for everyone to re-do the roof insulation, waterproofing, and it is better to do the external insulation than the internal insulation. Good thermal insulation. Hope mine can help you <>

Do you have any other questions?

Need. As far as the building structure is concerned, under the scorching sun, the surface temperature of the roof of the top floor can generally reach more than 65, which is not as good as the thermal insulation effect of the middle floor. Due to the direct sunlight throughout the day, the temperature of the west-facing room is 1-2 higher than that of the east-facing room; Coupled with the fact that the exterior walls are not thick enough and the insulation material is poorly insulated, it will make the room on the top floor more stuffy. If the insulation is done, the energy consumption of the floor will be lower in winter.

One. Pre-construction preparation of the purchase of main materials and their accessories: the main material is insulation board: you can choose insulation materials with good thermal insulation performance, non-toxic, no release of harmful substances and fireproof.

Two. Waterproof treatment prepared before construction: If it is moldy, it can be applied with anti-water paint.

Three. After preparation, now enter the construction state: draw the construction baseline: in order to paste the insulation board into a straight line during construction, the construction baseline needs to be drawn on the wall before construction.

Four. Adhesive insulation board: Apply the insulation board with the glue prepared in advance, which can be applied at intervals at the four corners and in the middle, so that the adhesive is more firm.

Hello, roof insulation is better indoors than outdoors, outdoor may not be well pasted after the sun and rain, and it is not easy to repair after being damaged. In addition to the wall, the roof of the house should also be insulated, so as to achieve the effect of comprehensive insulation. The roof insulation is generally chosen to be insulated outside the roof.

Outdoor thermal insulation construction is more convenient, and the thermal insulation effect is also better than indoor thermal insulation, indoor thermal insulation will occupy a certain space to make the indoor space height shorter, making people feel that they are suppressed. In short, roof insulation is still better outdoors.

Summary. The materials used for roof insulation are generally foamed concrete, foam glass insulation boards, phenolic resin insulation boards, etc. Foam concrete is a kind of thermal insulation material, which has good thermal insulation performance, fire performance and sound insulation effect.

Foam glass insulation board has the characteristics of light weight, small thermal conductivity, small water absorption, non-combustion, etc., and is usually used for some thermal insulation of civil building exterior walls and roofs. Phenolic resin insulation board has the advantages of light weight, fire resistance, non-embrittlement, etc., and is an ideal thermal insulation and energy-saving material at present.

The foaming glass insulation board has the characteristics of light weight, low thermal conductivity, low water absorption, non-combustion, etc., and is usually used for some thermal insulation of civil building exterior walls and roof cherry rocks.

Phenolic resin insulation board has the advantages of light weight, fire resistance, non-embrittlement, etc., and is an ideal thermal insulation and energy-saving material at present.

Some construction points of roof thermal insulation materials 1, the air insulation layer is respectfully informed that before laying, the sand particles, hard blocks and other debris on the surface of the base draft should be cleaned first, so as to prevent damage to the air insulation layer during paving. In the old loose, plate-like or overall insulation layer that has been paved, it is not allowed to walk directly and transport the trolley, and the walking route should be paved with scaffolding. 2. After the construction of the insulation layer is completed, the leveling layer should be paved in time to reduce moisture and water ingress, especially in the rainy season.

3. The materials before use should be selected in strict accordance with the relevant standards, and the storage and handling should be strengthened, and the materials that do not meet the requirements of the specifications shall not be used.

Precautions for installing thermal insulation ceiling 1, pay attention to the height of the ceiling The height of the ceiling is very important, too high or too low will affect the aesthetics of home decoration, usually after the installation of the ceiling, the most effective change can ensure that the remaining space is between meters and 3 meters, so that it is not only suitable for living, but also can play a good thermal insulation performance. If the ceiling is installed too high, its insulation effect will be affected, so the ceiling height must be designed before installation. 2. Pay attention to the direction of the circuit to install the insulation ceiling, we must take into account the direction of the circuit and reserve the space for jumpers, so as to prevent the wires from being in an overheated environment for a long time, resulting in rapid aging of the wires, and can also facilitate the later adjustment and processing.

Article summary: The above is all about what materials are generally used for roof insulation. If you want to know more about dry land, please continue to pay attention to Jiahe Youju.

1. External thermal insulation - glue the thermal insulation material to the outside of the building, similar to "wearing a cotton jacket".

2. Internal insulation - contrary to the above, stick the insulation material in the room, such as the practice of cold storage.

3. Sandwich insulation - a mature practice in Europe, when combining walls, there are hard panels on both sides and insulation materials in the middle. Don't think about this approach.

Specific suggestions: usually we pay more attention to the heat on the top, in fact, the wall is also a heat source, although the absolute temperature is lower than the ceiling, but the area of the wall is almost twice that of the ceiling, so the heat absorbed will only be more than the ceiling.

It is not possible to add an additional layer of insulation to the roof, only at home, that is, internal insulation. You can paste a 5 cm thick polystyrene board (that is, a styrofoam board) on the ceiling, and then paste a mesh cloth to reinforce, and the fan ash is basically the same as the original ceiling, only 5-6 cm lower.

If the room is large enough and you don't care about the smaller area you use, you can consider using the same method to insulate the walls. Theoretically, it is possible to save up to 60% of energy consumption. However, the usable area of the room will be reduced by about 5%.

Referring to the ** of external wall insulation in the north, it is estimated that the price of contracted labor and materials per square meter is between 50-80 yuan (including interior wall latex paint).
