Are you tired of being too hot in the summer and very cold in the winter in your home? Are you considering buying your new home but your insulation is outdated? Many solutions exist to remedy these thermal insulation problems. Overview.

How to spot poor insulation?

Very often, it is not necessary to resort to an in-depth thermal diagnosis to find that the interior insulation or the exterior insulation of your house is defective. The call to a professional allows of course to definitively validate your impressions of thermal discomfort, but if you notice that it is too hot in your attic in the summer or that you are very cold in winter, the observation of poor insulation is already evident.

Bad insulation: signs that never lie

Heat losses originate from obsolete insulation or non-existent insulation. The consequences are multiple: hot / cold drafts, temperature which varies rapidly depending on the outside temperature, humidity, mold, noise pollution linked to poor sound insulation, high energy bills … All these inconveniences are not inevitable: it is possible to put an end to it by opting for a new interior insulation of the attic or exterior thermal insulation (ITE). It remains to study how to choose the right insulators and the right professionals who will solve your insulation problems.

How to choose good thermal insulation?

The high energy consumption of your home, which causes your energy bill to explode (electricity bill, gas bill, etc.) can be reduced quickly with the installation of new thermal insulation. First of all you must establish, via a professional specializing in insulation work, where the problem comes from: roofing, walls, joinery… From there you can project yourself towards the new work.

Beforehand, remember to find out about financial aid from the State for energy renovation work. Many measures exist, such as the tax credit for the energy transition (CITE) which allows you to benefit, without conditions of resources, from a 30% tax credit on the total amount of work. ANAH helpers are also important, so don’t hesitate to contact them.

Choosing a good thermal insulation therefore depends on the genesis of the problem in your home. There is no shortage of insulation solutions.

Thermal insulation: what are the solutions?

If you have lost attics and these are not insulated, insufflation insulation is a very effective technique. It is a mineral wool insulation of natural origin which is blown and spread over the entire floor. Result: no more thermal bridges and heat loss! A thin addition of insulation can also be installed under the roof.

In convertible attics, under-roof insulation, presented in rolls and arranged on rails, effectively insulates the roof through which most of the energy losses escape (up to 30%).

But there is another insulation technique popular with professionals: external thermal insulation (ITE) . These are polystyrene panels fixed to the facade on which a finishing coating is applied. Thanks to its excellent thermal phase shift rate, this insulator has exceptional insulation characteristics. It allows a renovation of the facade to be finished in style, without any inconvenience during the renovation work.

Finally, joinery is of considerable importance in terms of energy losses. So think about modernizing your windows, roof windows and entrance doors to limit thermal bridges and condensations that lead to humidity.

Finally, all these renovations will allow better sound insulation, which will prevent hearing everything happening in the next room. An additional benefit for your comfort of life.

So do not hesitate to contact a renovation and insulation professional to carry out your work. This must imperatively be labeled RGE (Recognized guarantor of the environment) for you to benefit from the CITE tax credit.
