Is it OK to leave the exterior wall uninsulated? Does exterior wall insulation work?

Of course not, the advantages of external wall insulation outweigh the disadvantages of the building.

The functions of exterior wall insulation are:

1.Protect the facades.

As the surface layer of the building, the exterior wall is exposed to the wind and sun and is affected by the external climate, and if no protection is done, under this continuous aggression, the external wall of the building may face problems such as cracking, bulging, and even water seeping into the interior wall. As buildings are destroyed, the cost of heating and cooling also increases, affecting both the aesthetics of the building and the living of residents. Exterior wall insulation can effectively solve this problem, while meeting the thermal insulation of the building, it also greatly prolongs the life of the building and becomes the "bulletproof vest" of the building.

2.Thermal insulation, saving electricity bills.

After the building is insulated on the exterior wall, it can effectively insulate the heat, so that the indoor can store higher heat, and it can also be insulated, so that the wall structure can absorb or release heat, which is conducive to the stability of indoor temperature. In this way, the electricity bill is saved in disguise, and the building is warm in winter and cool in summer, making it suitable for living.

3.For the energy-saving renovation of old buildings, it will not affect the use of residents.

For the renovation of the exterior wall of the old building, only need to remove the original exterior wall decorative surface layer, repair and leveling treatment, paste the insulation board on its base layer, and then do the finishing layer, the exterior wall construction does not need to be relocated, the construction period is short, the environmental pollution is small, it does not affect the indoor living and use, and the old building can be replaced in a short period of time, and the social benefits can be achieved.

The economic and environmental benefits are significant.

Summary: Combined with the role of external wall insulation, the heat lost through the external wall in winter accounts for about 33% of the total heat dissipation, and the energy consumption is very serious. However, if the exterior wall insulation is done, the performance of the whole house will be improved a lot, and the insulation treatment does not have a complicated process, and it does not need to cost a high cost.

Is it okay to come to your exterior wall without insulation? I think it's okay for the exterior wall not to be insulated, so we can add insulation to the interior wall, so that the exterior wall doesn't have to be insulated, so I think the interior wall is insulated. The interior wall is warmed with insulation, so the exterior wall does not need to be added.

My likes, thank you.

If the villa is not insulated, and the exterior wall is directly decorated, then the thermal bridge effect will be very large, causing damage to the main body, which will seriously cause a large temperature difference between indoor and outdoor, and the living comfort will be extremely reduced, and even the decorative surface will crack with the main body of the building.

If it is a commercial house, it can't be done, and even the final acceptance and energy-saving inspection can't be passed, which is a construction deficiency and the consequences are very serious, which may directly affect the construction qualification level and later review.

If it is a self-built house, and you are the construction party, if it is discovered by the owner's family, the consequences are the same, and there are many cases of cutting corners in villages and towns every year because of construction, and the final success rate of the construction party is very small.

If it is your own house, whether it is through construction time considerations or to save money, you have the right to decide not to use external insulation, but it should be noted that in winter and summer, it doesn't matter if you can endure it without complaining or regretting.

If conditions permit, it is better to keep warm. Now the winter is getting colder and colder, the area of the exterior wall of the self-built house is relatively large, the heat lost through the exterior wall in winter accounts for about 33% of the total heat dissipation, the energy consumption is very serious, if you spend 10,000 to do a thermal insulation, the house is warm in winter and cool in summer, in the long run, the exterior wall insulation is still earned in living comfort and energy saving.

According to the requirements of energy-saving specifications, the exterior wall of civil construction projects should be insulated, whether it is external wall insulation or external wall insulation or other forms of thermal insulation: 1. Thermal insulation materials should be used in accordance with the requirements of the design drawings. 2. Retest requirements for insulation materials.

The wall energy-saving project adopts the guarantee.

Of course it works. With the development of the global economy, the energy situation is severe, and building energy conservation has become the trend of development in today's world. External wall insulation is currently vigorously advocated thermal insulation practices, so in addition to energy saving and consumption reduction, there are mainly the following benefits:

1.Long service life. Because it is on the outside of the building wall, it can make the temperature difference of the main structure in each season very small, reduce the influence of thermal stress on the main structure, effectively protect the main structure, improve the durability of the wall structure, and thus prolong the life of the building.

2.Improve comfort. The heat capacity of the base wall is generally much larger than that of the insulation layer, so the external insulation is beneficial to the thermal stability of the room.

During the heating period, when the heating is uneven, the base layer has a large amount of heat storage, which can ensure that the temperature of the inner surface of the exterior wall does not drop sharply, so that the indoor temperature does not drop quickly. In summer, the outdoor temperature rises, and due to the shielding effect of the external insulation system, the base wall heats up very slowly, which can provide a stable indoor temperature, which is conducive to improving the comfort of the human body. Overall, an external thermal insulation wall can make the room warm in winter and cool in summer, reducing the energy consumption of heating and air conditioning.

3.Improve the indoor environment. The external thermal insulation method is conducive to eliminating or weakening the influence of the thermal bridge generated around the junction of the internal and external walls, the outer wall ring beams, the structural columns, the frame beams and the junction of the top parapet and the roof panel, so that the heat loss at the thermal bridge is reduced, and can prevent local condensation caused by the low surface temperature of the thermal bridge in winter, and avoid the phenomenon of mildew, condensation, and cold penetration in the room.

4.Wide range of applications. The external insulation of the building wall is not only suitable for buildings that need heating in winter in the north, but also for air-conditioned buildings in the south that need heat insulation in summer.

It is not only suitable for the insulation of the masonry exterior wall of the brick-concrete structure building, but also for the insulation of the concrete exterior wall of the shear wall structure. It is suitable for both new construction and renovation of old buildings. When the building is renovated with external insulation, it can reduce the disturbance to the residents.

Since it is on the outside side of the building wall, the residents will not destroy the insulation when they renovate the house.

It definitely works!

I'll give you an example: the briquette stove, the one that boils water. It's made of insulation material, and it's very hot to put briquettes inside, but if you touch the outside, it doesn't feel so hot.

I gave this example just to show you that it was useful. But after doing the exterior wall insulation, you don't feel it so obviously!

Anyway, after the calculation, much more energy saving 50%, or more than 60%!

At present, there are two types of wall insulation: exterior wall insulation and interior wall insulation. Today I mainly talk about the benefits of exterior wall insulation:

As the name suggests, exterior wall insulation is a kind of thermal insulation practice that places the insulation layer outside the main wall material, because it can reduce the impact of the cold bridge and protect the main wall material from much temperature deformation stress, which is the most widely used thermal insulation practice at present, and it is also the thermal insulation practice vigorously advocated by the state at present.

Due to the occurrence of a number of building insulation fire incidents in recent years, it has triggered the thinking of insulation and fire prevention from all walks of life, and the fire performance of insulation materials has attracted unprecedented attention from all walks of life in the industry. However, many insulation materials are produced during the construction process, such as: electric welding, open flame, and poor construction habits.

The melt droplets and toxic fumes continuously produced during the combustion process of these materials, and the harm to the environment caused by the chlorofluorocarbons, hydrofluorocarbons, freons and other gases released at the same time cannot be ignored. Therefore, the fire resistance of insulation materials cannot be ignored.

Exterior wall insulation: It has a protective effect on the main structure, avoids large temperature changes in the main structure, and helps to prolong the life of the main body; Favorable and elimination and attenuation of the thermal bridging effect of excessive local heat transfer; Avoid large fluctuations in room temperature; External insulation can avoid damage during decoration and does not occupy indoor area.

Exterior wall insulation is more energy-efficient than other insulation materials, which has been recognized by more and more customers and has become a widely used insulation method.

The exterior wall is well insulated. The differences between the two in terms of structural protection, thermal insulation effect, and occupied space are as follows:

1. Structural protection is different

The advantage of external wall insulation is that it is more conducive to protecting the main structure of the house and prolonging the life of the building.

If the external insulation of the exterior wall becomes the internal insulation of the exterior wall, the load-bearing wall and parapet of the exterior wall will omit the insulation material, and the mortar thickness of the exterior wall will also become thinner.

2. The thermal insulation effect is different

The external insulation structure of the exterior wall can promote the indoor temperature of the house to maintain a relatively constant temperature, which is conducive to improving the quality of the indoor thermal environment. The material requirements for external wall insulation are stricter and more demanding than those for external wall internal insulation. The internal insulation of the external wall is prone to mold and other phenomena of the internal wall.

The internal insulation structure will cause two temperature fields to appear on the interior and exterior walls, forming a temperature difference, which will cause instability in the building structure.

3. The space occupied is different

The internal insulation structure will reduce the usable area of the commercial house, and at the same time affect the secondary decoration of residents, and the internal wall hanging and fixed objects are easy to damage the internal insulation structure.

Do the math how much it will cost you to renovate your home

Wall insulation is a very important step in the construction process, which can not only improve the living comfort of the owner, but also extend the service life of the building, but the wall insulation is also divided into two types: external wall insulation and internal wall insulation, the two situations are different, and the controversy is relatively large. So, is it useful to insulate interior walls? What are the wall insulation materials?

Let's take a brief look at it below.

1. Is it useful to insulate interior walls?

The thermal insulation effect must be there, but if only the interior wall is insulated, the moisture of the exterior wall is easy to enter the interior along the wall, and eventually condenses into water droplets, affecting the effect of thermal insulation.

Second, what are the wall insulation materials?

1. Aluminum silicate insulation material: This is an emerging environmentally friendly building material, with natural fiber material as the main material, made by composite processing, during construction, only need to add an appropriate proportion of water, smeared on the surface of the wall, very convenient.

2. Phenolic foam material: This material is an ideal material for thermal insulation, with a lot of high-quality properties, and light texture, easy installation, suitable for the environment of minus 196 degrees Celsius to 200 degrees Celsius, even if the temperature is low, it will not be embrittle.

3. Inorganic thermal insulation mortar: This is a material suitable for external wall insulation, mainly using thermal insulation particles as the main raw material, and then adding cementitious materials and other fillers, which can play a good thermal insulation effect, and at the same time can also be fireproof and anti-freezing, cost-effective.

4. Rubber powder polystyrene particles: this insulation method is to use dry mix mortar as the main cementitious material, and then add an appropriate amount of anti-crack fiber, which can be used by on-site deployment, and the insulation effect is very good, and the interior and exterior walls can be used.

Summary: The above is useful for interior wall insulation, and the wall insulation materials are introduced here, I hope it will help you. If you want to know more about related information, please pay attention to Qeeka Home.

The prohibition of external wall insulation does not mean that it is prohibited to heat external walls.

Exterior wall insulation. 1. Prohibition and restriction of external wall insulation protectionThe masses of the peopleThe safety of life and property is of great significance.

In recent years, the building structure.

Accidents such as the external thermal insulation material falling off and injuring people, and the external thermal insulation material of the external wall causing the building to burn to the end occur from time to time, which has seriously endangered the safety of people's lives and property and caused adverse social impacts.

Exterior wall insulation due to "cracking, hollowing."

Abscission; Insulated but not flame retardant; flame retardant and can not meet the requirements of energy-saving building insulation", some provinces and cities have issued relevant policies to prohibit most of the external wall insulation system, including all kinds of boards.

The thin plastering external thermal insulation system and the thermal insulation decorative integrated board system. The prohibition of external wall insulation is the supervision of the insulation material industry, as long as the good products can be recognized, and the safety of people's lives and property can be guaranteed while achieving the thermal insulation effect.

The façade was rebuilt. Second, of course, the exterior wall still needs to be insulated.

As the outer layer of the building, the exterior wall is exposed to all external climates, such as heat, cold, freezing, snow, hail, rain and wind. Rainwater, temperature changes, and environmental pollution alternately and continuously act on the exterior wall, causing cracks and mold on the exterior wall. Buildings have been damaged, and the cost of heating and cooling has increased dramatically.

The value of an external thermal insulation system is much higher than its own cost compared to the cost of expensive building repairs. It "wraps" and protects the appearance of the building, which greatly extends the life of the building while meeting the thermal insulation performance of the building.

Exterior wall insulation construction.

Exterior wall insulation not only protects the building and prolongs the service life of the building, but also helps to maintain a stable room temperature and achieve the purpose of energy saving and consumption reduction.

That's all for the subject. However, I would like to remind you that there are many types of insulation materials on the market, and you must choose carefully when doing exterior wall insulation, and choose big brands and high-quality insulation materials to avoid detours and ensure the subsequent use effect.

I want to know that all parts of the country have contributed to the insulation of the exterior wall, and the exterior wall cannot be insulated in the future? Yes, the current exterior wall insulation is foam, is a non-fireproof material, there are many fires caused by exterior wall insulation, so now all parts of the country are limited to exterior walls, insulation, and exterior wall insulation should be done in the future, and some refractory materials can be used.
