In the south of France, heat waves are becoming increasingly frequent and intense. For residents and building professionals alike, the issue of summer comfort in homes is now a key consideration in energy renovation projects.
How can we prevent houses from turning into veritable "heat traps" during heat waves? For many insulation specialists, the answer lies in choosing the right material.
Based in the Béziers region for over fifteen years, Domiso Isolation made the decision to use cellulose insulation very early on. cellulose insulation to improve the thermal comfort of homes, particularly in summer. Its director, Philippe Germier, shares his feedback after more than a decade of projects in a region particularly exposed to high temperatures.
As summers become hotter, insulation becomes strategic
In the south of France, periods of intense heat are becoming increasingly frequent. Heat waves are becoming more common, and the issue of summer comfort in homes is now a major challenge for energy renovation professionals.
In this context, the thermal insulation of the building—and in particular that of the roof—plays a decisive role in limiting heat gain in the home and improving occupant comfort.
For many professionals in the sector, cellulose insulation is now a particularly effective solution for improving thermal comfort in summer.
A company specializing in energy-efficient renovations for 15 years
For more than fifteen years, Domiso Isolation has been assisting individuals with their interior thermal insulation projects.
Its director, Philippe Germier, works mainly on energy renovation projects in the south of France.
From the moment he started his business, he chose to work with a material that was still relatively unknown at the time: cellulose insulation.
Why choose cellulose insulation insulate your attic?
The choice of cellulose insulation was cellulose insulation made by chance. For Philippe Germier, it was a question of finding an insulating material that combined thermal performance with environmental considerations.
"I started the business with cellulose insulation. I wanted a product that stood out and was environmentally friendly. A colleague introduced me to cotton wool and showed me all its qualities in the home."
Discovering the properties of the material will quickly convince the entrepreneur.
"I discovered a bio-based, breathable insulation material with very strong technical properties and very long phase shift times. That convinced me to start my own business using this material."
Summer comfort: a key advantage of cellulose insulation
In hot regions, one of the main challenges of insulation is to limit overheating in homes during the summer.
"In summer, temperatures in attics can easily reach 55 to 60°C. Here in the south, when it's 35°C outside, the heat is very intense."
cellulose insulation in particular for its thermal phase shift capacity, i.e., its ability to delay the transmission of heat into the building.
"When you manage to gain two or three degrees in a house thanks to attic insulation, people really feel the difference."
Tangible benefits for occupants
After fifteen years in business, Domiso Isolation has accumulated a wealth of feedback on the performance of cellulose insulation.
"To date, and for the past 15 years, we have had no negative feedback. We only have satisfied customers."
"Before the work was done, some customers had to set their thermostat to 24°C to achieve a temperature of 20°C in their home. Now that the attic has been properly insulated, they set the thermostat to 20°C and the temperature in their home is actually 20°C."
Why Domiso Isolation works with Igloo
For its projects, Domiso Isolation has been sourcing its materials for many years from Igloo, a French manufacturer of cellulose insulation.
"Igloo is a French manufacturer that has all the industrial processes necessary to produce high-quality cotton wool. To manufacture a high-performance fiber product, you need the right facilities. I have had the opportunity to work with other cellulose insulation manufacturers, but in terms of fiber product quality, there is no comparison."
"We have a very close relationship with the teams. There is communication and genuine closeness. This is important to us in our professional approach to clients."
An insulation solution adapted to current climate challenges
With summer temperatures on the rise, the issue of summer comfort is becoming a key topic in energy-efficient renovation.
For building professionals and homeowners alike, attic insulation is often one of the most effective ways to improve thermal comfort.
After more than fifteen years of projects in the south of France, cellulose insulation a reliable solution for Domiso Isolation to improve the comfort of homes in the long term, both in summer and winter.
