QUESTION: Insulation: how to avoid condensation and mold during insulation?

Question

Accepted Answer

Preventing the appearance of condensation and mold during insulation work requires a comprehensive engineering approach and a strict sequence of actions. First of all, it is necessary to thoroughly work out safety issues and all hidden engineering, including electrical wiring, water supply communications, and the ventilation system. Only after the complete completion of these stages can one proceed to the installation of thermal insulation, subsequent finishing, and room decoration, which minimizes hidden problems in the future.

Special attention should be paid to calculating the dew point, the correct placement of vapor barrier films, and maintaining natural air exchange in the rooms. Errors at material joints or the lack of a ventilation gap can lead to moisture accumulation inside the wall, which will inevitably cause fungus to appear.

In order to protect your home from dampness and maintain a healthy microclimate, it is recommended to adhere to the following proven work procedure.

1. Audit the existing ventilation and, if necessary, install supply valves or forced exhaust systems.
2. Install a high-quality vapor barrier on the warm room side, carefully sealing all seams and joints with special tape.
3. Ensure a ventilated air gap between the insulation and the cladding material when insulating facades externally.
4. Monitor the humidity level in rooms using a hygrometer and regularly ventilate the rooms during the off-season.
5. Check the quality of the abutment of window and door blocks, eliminating any thermal bridges with mounting foam and sealants.
