Sometimes it is impossible to protect your house from low temperatures externally, so carrying it out on the inside is the only way to go. Such operation undertaken from the inside, however, is more hazardous than traditional external solution.
There exist various determinants that can make it difficult.
Specialists state that insulating surfaces internally is less profitable than doing it externally. Nonetheless, there are circumstances when it may only be executed from the inside. Insulation from the inside is infrequently applied since it implies many issues. It is more intricate and tricky than the warming of the building externally, known for decades, so resolutions were drawn from the mistakes made and a few ideas were recommended that get rid of most of them. The main issue in a structure insulated internally is that after such a procedure its construction (external walls, ceilings) is ubicated in the unheated zone. When there is no insulation, the whole wall has a significantly higher temperature (to our disadvantage, due to the high heating expenses) and only a small outside fragment is below 0 ° C. After installing the insulation internally, the temperature below 0 ° C will apply to the bigger thickness of the wall, because the warmth will cease passing through it. That makes the wall significantly colder and more susceptible to low temperatures.
Providing insulation from the inside, the surfaces must primarily be protected against humidity. The infiltration of water vapor coming from inside the building into the center of the obstruction is counteracted by vapor barrier with a properly selected diffusion resistance coefficient.
