Uniso: The sustainable EWI solution to retain heat and reduce bills

As winter approaches, many households are dreading another rise in heating bills. This is especially true given that more than one in three French people (36%) consider their current home to be energy inefficient. For 63% of them, the main cause cited is poor thermal insulation[1].

In this context, controlling energy consumption becomes crucial and external thermal insulation (ETI) is emerging as an effective solution to improve comfort while achieving significant savings on energy bills.

According to Antoine Vincenot, director of Uniso France: "External thermal insulation (ETI) helps retain heat inside the house and prevents energy waste. It's a concrete way to reduce expenses and improve comfort, especially during the colder months."

What is external thermal insulation?

External thermal insulation (ETI) involves wrapping the house in an insulating layer installed on the outside, eliminating thermal bridges and increasing the building's thermal inertia. It guarantees:

A consistent indoor temperature;
Protection against cold and damp;
Improved air quality and mold prevention;
Reduced energy consumption leads to lower bills and thus a reduction in greenhouse gas emissions from the home;
Easy installation with no impact on the daily lives of residents.

"I can see the difference on my bills. I've reduced my electricity consumption by about €40 per month." Nelly Castaing – Gujan-Mestras

The advantages of the Uniso solution

For 35 years, Uniso has offered a unique, ready-to-install solution on the market for exterior thermal insulation. Its patented all-in-one system, designed and manufactured in France, allows for the insulation, renovation, protection, and beautification of all types of facades.

High-performing and durable

PIR polyurethane panels, among the thinnest available, offer optimal thermal insulation thanks to their perfect airtightness and watertightness, as well as high impact resistance. This solution can reduce a home's energy costs by up to 50%.

For a typical project involving 100 m² of installed Uniso facades, the figures are:

1.000 recycled aluminum cans,
500 plastic bottles,
2 old PVC windows reused.

According to Antoine Vincenot, director of Uniso France: "Energy renovation is one of the major levers for reducing CO₂ emissions from buildings. And with the Uniso solution, we have a system that combines thermal performance, durability, aesthetics and a strong environmental commitment."

Easier maintenance, increased lifespan

Maintaining Uniso EWI is simple: the lacquered aluminum surface requires no refinishing and, thanks to its non-porosity, it is easily cleaned with suitable products.

The numerous available finishes allow for a uniform, elegant, and polished facade. With an estimated lifespan of 50 years, Uniso panels also represent a true aesthetic asset.

"It's a transformation that makes you want to stay in the house for a long time." Mrs. Meynier – Sciez

Finally, installation is quick and intuitive, comparable to that of a floating floor, and can be carried out in any season, summer or winter. Whether by a professional or an individual, the installation of Uniso EWI is accessible and reliable.
