Will removing the insulation on the walls of the balcony on the top floor cause water leakage?

If it is knocked out, the glass window of the closed balcony has better thermal insulation performance. Otherwise, it may be cold in winter. This depends on the winter temperature in your area.

If it is a warm balcony and the insulation layer of the exterior wall (on the main wall), and you want to paste wall tiles, you must remove it.

It needs to be eradicated. Thermal insulation is generally divided into internal insulation and external thermal insulation, external thermal insulation is done on the exterior wall and open balcony wall, the material is generally extruded plastic board or thermal insulation mortar, the exterior wall has nothing to do with the interior decoration, if it is on the balcony, it is recommended to shovel off, otherwise the balcony wall is easy to fall off after the wall tiles, if it is paint, it doesn't matter.

The insulation layer should be shoveled off.

It is important to shovel off the insulation layer because the insulation layer is made of asbestos net and foam, it is not flat, and there is no other way to receive the moisture in the cement. >>>More

The insulation layer of the inner wall of the balcony is cut off with a shovel, and the foam at both ends of the insulation layer is cut by the shovel, and the foam is exposed, and the mortar is smeared and then decorated with the surface layer, so that the decoration is good-looking.
