Being one of the big topics of the moment, the insulation of windows is an important factor pledge of economy and a better development of your habitat. Since the appearance in 2007 of energy performance diagnostics for real estate, many homeowners have taken into consideration the benefits of good window insulation. But how do you make real savings and what are the important criteria to consider? Among the misconceptions and marketing slaughter, the editorial staff of déco.fr offers you to make it a point to find your way around and make the right choice.

Are we really losing energy through the windows?

You should know that the heat loss in a house is through the outer walls. Good insulation goes through the windows but also through the insulation of the whole house. Walls, floors, ceilings, roofs are also walls that allow heat to escape. Changing your windows will certainly improve your comfort and the energy performance of your home, but it is better to think of insulation as a whole!

Do you really save money by changing your windows?

Concretely changing the windows of your home represents between 5 to 30% of your heating bill. A significant cost especially when the latter follows the course, still rising gas for example or the price increases imposed.

What type of insulation should I choose for my windows?

Performance depends on two main factors. The first is related to carpentry. PVC, aluminum, or wood, each one has an interest! It is up to you to choose them according to your criteria. For example, PVC is recognized for its excellent insulating qualities. However, if you are renovating an old house, it is better to respect the charm of the place by choosing wooden joinery. They also have good thermal insulation, they are much more elegant and warm than PVC or aluminum. The second factor to take into account is the performance of the glazing. Double glazing, triple glazing, reinforced with argon gas or air space all depends on your orientation and the insulation of your home. Don't be convinced by "triple glazing is better than double!". First you need to take stock of your insulation in general. Triple glazing will be useless if your house is poorly insulated!

How to increase my energy performance with my windows?

The course of the sun is an imploring factor! If you are thinking about building your home, or even if you are renovating, take a good look at the orientation of your home. As you can imagine, the south-facing openings guarantee that you will be heated by it in winter! While facing north, it will be better to invest in high-performance and quality insulation. Also, don't overlook the importance of curtains and shutters. In addition to being aesthetic, they also have their role to play in good thermal insulation.
