The losses caused by the openings of a house in terms of energy are considerable. That especially generates important repercussions in terms of energy consumption of the expenditure of heating. To reconsider its construction in a green logic, consists mainly on this level to improve the insulation of the doors and windows.
The double glazing principle of operation
The double glazing offers an alternative of insulation adapted to the openings of a house. It in particular makes it possible to limit the thermal losses and must thus for that constitute the first thing to be made during a restoration. The double glazing offers also the advantage of a more important sound insulation.
This system consists of a double wall of glass separated by a closed hermetic space where space empties thus formed is called blade of air. This space can contain is air or gases dehydrated like argon or krypton. The inert gases are privileged from their less conducting nature of heat. The installation of this kind of equipment makes it possible to save up to 10% of the consumption of heating.
The installation of window with double glazing must be combined with a frame of window also optimized for a more powerful insulation. The studies on the subject show that PVC joinery remains most effective, then those of wood and finally the metal structures.
The advantage of the recourse to this kind of element is the assistance which offer the State with the private individuals which carries out of work of improvement of the energy performances. That results in particular by tax credits of the subsidies of the ANAH, but also in loans. The latter can deal with part of the capital expenditures if it is not in their totality.
To apply the double glazing to its windows
The double glazing is a measurement which enters the field of evaluation of the thermal regulation. To suppress the expenditure of heat, the reduction in energy consumption must relate indeed to a better insulation.
The thermal regulation is a legal tendency which makes it possible to compare the energy consumption of a construction compared to that of another with the same geographical characters and same technical specificities. It is within the framework of the regulations thermics 2005 and 2012 that the recourse to the double glazing is recommended to increase the insulation of a house.
Concretely, the use of this technique makes it possible to bring in summer the heat of the external medium and in winter to avoid losing interior heat. The replacement of the traditional windows increases the dispersion of heat clearly. The suggested solutions can be the double glazing, the triple glazing or the high-output glazing.
It is the requirement to limit the losses of energy of the openings and the elements of the structure. The choice of this solution is shown more difficult to implement than the insulation of the walls, but the advantages which come out from it cannot be been unaware of.
Moreover, the public powers grant in certain cases of the special assistances for the people wishing to install windows equipped with such a manner. These accompaniments concern the owners as well as the tenants of dwelling, what to encourage the use with this technique. |
