External wall insulation is such a type of insulation, which is considered the most suitable and optimal. Internal wall insulation has only a positive effect. The main disadvantage of the outer insulation in comparison with the thermal insulation of the internal is the seasonality of construction work. The facade should only be insulated in dry weather.
The insulation process must be performed in a certain sequence. On the enclosing structure on the outside, it is necessary to fix the insulation, and on top of it it is necessary to equip waterproofing. As a rule, it mainly is a liquid material, while traditional prototypes from the film are used for roofs. If in the future you plan to sheathe your home through siding, then in this case it is better to use budget, but the same effective material is a regular plastic film. Waterproofing is needed so that moisture does not fall into the insulation, which negatively affects its thermal insulation properties. After applying the waterproofing layer, you need to lay the finishing layer of the facade of the building.
External insulation preserves the walls well, and the thermal insulation layer can save them from the aggressive effects of temperature conditions, which can significantly extend the life of the building. Due to the fact that the insulation is located outside the wall, it retains heat and naturally thermal insulation makes it much more efficient.
