To enjoy interior comfort and reduce your heating bill, it is essential to eliminate thermal bridges in the house. But to do this, we must already identify them in order to remedy them. Components of a poorly assembled wall, surface losses, poor insulation, poorly adapted construction process: the advice of a professional is necessary. Once the thermal bridges are detected, they can be neutralized. Between exterior insulation and interior insulation, there are solutions.
What is a thermal bridge?
A real scourge in a house, the thermal bridge is responsible for heat loss. This results in a loss of interior comfort and excessive energy consumption. The impact on the environment is negative, not to mention that thermal bridges generate expenses that we would do well. You should know that a material that lets heat in summer and cold in winter is a thermal bridge. The phenomenon of thermal bridges concerns both the walls of an individual and collective dwelling, a ceiling, a slab or even a floor when they are poorly insulated. Once detected, they can be neutralized. The intervention of a professional is absolutely essential.
Limiting the effects of thermal bridges
It is urgent to find the best solutions to limit the negative effects of all the thermal bridges noted in the home. This will have the immediate effect of reducing, at least in part, the energy losses. The most economical solution is to intervene in the home with specific insulation. It is the ITI or Thermal Insulation by the Interior. One can for example put on the cold wall a polystyrene plate then a plasterboard. Polystyrene is a good thermal bridge breaker. However, this action is not sufficient to intervene on the origin of a thermal bridge. A floating slab can also be laid on a low floor.
Act from the outside against thermal bridges
To take the problem at the source, the best solution - certainly more expensive - is to have an ITE installed, that is to say thermal insulation from the outside. In this way, all thermal bridges are permanently eliminated and the thermal uniformity of the walls is increased. This solution is also interesting because it does not reduce the living area. It can be doubled by an interior insulation, which will have the effect of optimizing thermal comfort and making real savings.
Choosing the right constructive mode
It is important to be well informed about thermal bridges when planning or building a house, and to take into account the coefficient of thermal conductivity specific to each of the materials chosen. It is of course useful to opt for the best construction method in order to minimize the risk of surface losses. This will avoid unpleasant surprises. The most convincing example is the construction of aerated concrete blocks. A little more expensive, terracotta brick offers excellent results since it reduces the impact of thermal bridges by almost 40%.Installing a window seal Our practical DIY videos
