Thermal insulation: a key factor in summer comfort
As heat waves become more intense, the performance of insulation can no longer be assessed solely by its thermal resistance (R) or lambda (λ). Two materials with the same R-value can provide vastly different levels of comfort in the summer. Why? Because some insulation materials significantly slow down and dampen heat transfer, while […]
Summer comfort: a key factor for insulation professionals
Summer comfort has become a major concern in insulation. Thermal mass, phase shift, and the choice of insulation material all determine a building’s ability to prevent overheating, particularly in unused attic spaces. This is an essential technical consideration for professionals.
Summer comfort in the south of France: a craftsman's experience with cellulose insulation
In the south of France, Domiso Isolation is using cellulose insulation improve summer comfort in homes. Feedback from a craftsman with 15 years of experience on construction sites.
Why does the density of insulation change in unused attic space?
In attic spaces, two insulation materials can have exactly the same thermal resistance (R) and yet provide very different levels of comfort for occupants. This situation can be explained by a parameter that is often underestimated: the density of the material. Understanding the role of thermal phase shift and the dynamic behavior of insulation materials allows us to go beyond a reading that is solely focused on […]
Which insulation materials are most effective against heat waves?
With increasingly hot summers and more frequent heat waves, France is facing a major climate emergency that directly impacts how we design and renovate buildings. Faced with this new reality, the building sector can no longer be content with simply providing comfort in winter. […]
How can we ensure comfort in buildings during the summer?
One of the effects of global warming is an increase in heat waves, their duration, and their intensity. France is particularly affected by these extreme temperatures, mainly due to the density of buildings, impermeable soils, and the lack of vegetation in certain regions. So, what are the factors that influence […]
How can you optimize summer comfort with RE2020?
Effective January 1, 2023, the 2020 environmental regulation (RE2020) replaces the previous 2012 thermal regulation (RT2012), which governs building construction. It focuses on three new objectives: reducing the carbon impact of buildings, optimizing their energy performance, and ensuring summer comfort. In this article, we will explain what […]
