While winter is still in full swing, it’s time to check that you don’t heat your interior unnecessarily.
Whether your interior is heated with electricity, fuel oil or even wood, you may well spend a fortune without it is effective if your home does not retain heat properly. In this case, increasing the heating to have a good comfort temperature is useless, because it is a bit as if you left the window open permanently. The insulation of the house is therefore essential to avoid too high energy bills and gain in thermal comfort. And to find out if your house is isolated enough for the heating to evaporate in the wild, there is a very simple test when it is very cold. So don’t wait for the end of winter, it’s time to get answers.
In a house, a particular place is the main responsible for heat loss. It is considered that around 25 to 30% of the heat escapes by the roof if the insulation is not sufficient. For what ? Simply because the heat rises naturally and without an effective barrier, it will therefore escape directly outwards. Good insulation of the roof and attic therefore makes it possible to reduce the heating consumption in winter and it will limit the entry of heat in summer. The government also encourages the insulation of roofs to reduce heat losses, reduce energy consumption and limit greenhouse gas emissions, by offering financial aid such as Maprimerénov ‘and savings certificates energy (CEE).
To find out if your roof is isolated enough, the operation is very simple since it is enough to leave the house in the morning in frost or snow and observe the roof. If frost or snow uniformly covers your roof, this is a sign that it is correctly isolated. If there are areas where frost or snow has melted unevenly, it may indicate poor insulation of the attic. The heat which then escapes by the roof undoubtedly caused the melting of snow or frost in certain places.
The insulation of the attic, whether arranged or lost, is therefore a priority to improve the energy efficiency of a housing. Several solutions exist such as glass or rock wool in roller or blowing, ecological and efficient cellulose wadding, and insulating polyurethane, polystyrene or wood fiber panels suitable for fitted attic.
