Summary of common problems in the application of exterior wall insulation mortar

There are two main types of insulation mortar materials currently used for building exterior wall insulation: one is inorganic vitrified microbead insulation mortar; the other is organic rubber powder polystyrene particle insulation mortar. The main applications of insulation mortar are as follows: a question.

Empty drums, falling off, poor adhesion or cannot be stable for a long time: mainly because the organic materials in the mortar are aging, the mortar performance cannot be played normally, or the interface of the insulation layer is not handled properly. The construction is not done in accordance with regulations. question.

Thermal insulation performance; Thermal insulation efficiency depends on the thermal insulation performance of the exterior wall insulation material and the thickness of the insulation layer. If it does not reach 50% or 65%, it is mainly a problem with the insulation material. .

Cracks and cracks: Improper use of raw materials in thermal insulation mortar, unreasonable formula, weak water retention and humidity control capabilities, and poor drying shrinkage resistance of the mortar.
