When renovating a new house, should the wall insulation be removed?

1. What is an insulated wall?

1. Definition:

As the name suggests, in order to maintain thermal insulation and maintain indoor temperature stability, the insulation material is used to be fixed with the building wall in a certain way to increase the wall's An engineering practice for the thermal insulation or thermal insulation effect of a body.

2. Classification:

According to their location, thermal insulation walls can be mainly divided into: external wall insulation and internal external wall insulation.

2. Does the insulation layer need to be removed?

In fact, I am very confused about whether to remove the inner insulation layer. Generally, there are two reasons:

1. The area becomes smaller, which leads to many owners having opinions;

2. Cause latex paint to crack or wall tiles to hollow and fall off.

And I heard that many communities do not have internal insulation layers, so I became more determined to remove the internal insulation walls.

But here is a reminder from the editor:

The insulation layer can be divided into an outer protective layer and an inner insulation layer. The outer insulation layer must not be removed, but the inner insulation layer can be removed. of!

Of course, internal insulation and external insulation are relative under certain conditions, such as a balcony (or terrace);

If the balcony is sealed, it is recommended to remove the insulation layer;< /p>

If due to personal needs or community property regulations, the balcony (especially the terrace) is not allowed to be closed, the external insulation must not be removed, otherwise it will have a great impact on the thermal insulation effect of the house!

In addition, the quality of general indoor insulation walls also needs to be scrutinized, because developers may make them casually to cope with inspections. Therefore, if residents do not know the quality, they may crack after a few years. If it is not removed, the cracks in the wall will be difficult to repair.

3. What are the pros and cons of removing the inner insulation layer?

Now that we know that the inner insulation layer can be dismantled, let’s talk about the pros and cons of dismantling the inner insulation layer.

1. Advantages of disassembly:

(1) Disassembly Internal insulation can increase the indoor net usable area;

The internal insulation layer is generally 5 to 10 centimeters thick, so no matter which functional space it is in, the net usable area of ??the space can be increased after removal.

(2) Prevent latex paint/wallpaper from getting moldy, cracking and falling off;

If the inner insulation layer material used by the developer is not good enough, mold will easily occur. In places where the temperature difference is relatively large, the indoor and outdoor temperature difference is too large, thermal expansion and contraction, which will lead to cracks in the insulation layer.

Since insulation nails are required when the inner insulation layer is fixed to the building wall, removing the inner insulation layer can prevent the wall from getting damp, or improper construction causing the background color or shadow of the wall wallpaper to be exposed.

(3) Prevent large areas of hollowing or even falling when laying bricks on the wall;

Generally speaking, some remedial measures are needed after removing the insulation wall. For example, if the inner insulation wall of the balcony is demolished, the base layer must be processed (re-hanging netting and dusting) before tiling.

(4) Facilitate later wall installation;

For example, when installing wall cabinets on the balcony, holes need to be drilled, and it is not easy to drive nails into the inner insulation layer, so there is Great insecurity.

2. Disadvantages of demolition:

(1) The lack of insulation will definitely affect the indoor temperature, and turning on air conditioning in winter and summer will also consume more electricity.

(2) Increase the decoration cost, and the leveling of the base layer after eradication may also increase the cost.

(3) In winter, the wall is relatively cold and the indoor temperature is high. When the hot air hits the cold wall, there is a possibility of condensation and sweating.
