The thermal insulation of walls from the outside is a well-known concept, but very effective: in these times when energy savings are at the heart of all discussions, the ITE market increased by 5% in 2018. This trend has in particular been inspired by renovation aid. The French now know that in order to reduce heating expenses, it is important to invest first in devices aimed at limiting energy loss. The ITE offers many advantages in this, starting with a saving in space compared to conventional insulation.
The advantages of insulating walls from the outside
Opting for thermal insulation from the outside means first of all benefiting from space savings because the interior volumes will be preserved. Note that a layer of insulation is 100mm thick. If you opt for two layers, they will be 140mm: the gain in floor space is still appreciable if we compare to the insulation from the inside.
Thermal insulation from the outside contributes mainly to eliminate thermal bridges. You will no longer have to fear cold walls, freezing heat exchanges and humidity that tends to infiltrate. Thermal comfort will be optimal since your home will be well insulated in all seasons. And if there is an advantage that should not be forgotten to mention, it is the return on investment: with the high energy performance of the ITE, it is obvious that the savings on the heating bill will be very quickly visible.
The use of thermal insulation from the outside facilitates construction site : you are not disturbed by scaffolding, and do not need to empty your rooms. You can have an overview of the different types of insulation used via specialized platforms like Zolpan: the brand is aimed at professionals and individuals, with product references that aim to embellish and protect the facades as well as the interior of buildings.
If thermal insulation from the outside is meeting more and more success, it is because it also preserves the facade in the long term. If you decide to resell your property, know that this is in your favor.
Aids to encourage thermal insulation from the outside
State aid provided for this purpose will allow you to finance your thermal insulation project from the outside. You will find the Tax Credit for the Energy Transition (CITE), as well as the Total Energy Premium and a reduction in the VAT rate. You can also take out an Eco-Loan at Zero Rate. Note that aid from the National Housing Agency (ANAH) mainly favors low-income households.
Remember that the Isolation Tax Credit or CITE scheme will end in 2020. So if you have planned to install thermal insulation from the outside, it’s now or never. As of January 1, 2020, only low-income households will be able to benefit from this aid, under the RT 2012 standard.
You can also claim an insulation tax credit to finance the development of the attic, crawling, garage insulation, ceilings and floors. Please note, you have a few weeks left to make your request, before January 1, 2020!
