Guide to roof insulation for architects (anti-margoulins for others)




by Christophe » 12/11/23, 13:25

A Guide (Belgian and very complete: more than 150 pages) on thermal insulation techniques and particularly that of roofs.

To read for all those who have a project in mind before contacting professionals given the margoulins and shenanigans in the field in France currently (thanks to the 1€ insulation).

Intro:

The intervention of designers is essential because it is their responsibility to integrate the performances to be achieved, from the initial stages of the design process. These performances should not, however, hamper their creativity; on the contrary, it is a question of constructing buildings combining
beauty, comfort, durability and economy.

Aware of the importance of the information to be provided to professionals on the one hand and to the public on the other, Wallonia has set up, for several years, a multifaceted information and training system, relaying the research carried out by the Scientific Center and
Construction Technology and Universities.

A series of 9 practical guides for architects explored the envelope design methodology. Its authors, Francy Simon, Professor Emeritus at the Catholic University of Louvain, and Jean-Marie Hauglustaine, lecturer at the University of Liège, continue here
this approach for the thermal insulation of roofs (sloped and flat), offering a coherent approach, from the sketch to the project.
In this guide, the architect will find an integrated conceptual approach allowing him to guide and adapt his choices.

Other guides are distributed by the Construction Professional Training Fund, while individuals can find brochures and advice that go in the same direction, from the Guichets Energie Wallonie.

These achievements are part of the policy that Wallonia has been pursuing for several years to promote the Rational Use of Energy (URE) in buildings. Belgium has in fact committed, in Rio, in Kyoto then in Paris, to reduce energy consumption and therefore CO2 emissions, in order to reduce the greenhouse effect.

The main thing is the insulation of the "top".

For the walls, we can be satisfied with good insulation, nothing more.

He means a good one on the walls and a better one on the roof... : Cheesy:

Otherwise we can read the document…

I went through it quickly. It actually seemed very well done to me.

Search for Grandpa Claude on the tube.

Well, you have to hold on, he has a "bowl" not possible, it affects the contents a little, but he says that you need excellent insulation on the roof, and suitable insulation for the walls. Over-insulating will yield less than heating with the sun, simplifying the idea.

At the very beginning of awareness of the need for "suitable" insulation, the Erika concept was promoted (with a blonde, supposedly Nordic girl!), for "cost-effective thickness of insulation". I have always been deeply doubtful as to the validity of such calculations which were only accurate at the time of construction: the insulation represents only a fraction of the cost of the operation and the labor item is generally little affected by additional thickness. Anyone who did not take this concept into account and invested more in insulation, even if it meant making savings in the heating installation, was systematically winning with the upward variations in energy, whatever they may be.

...I add a layer, for the sake of cohesion: the advantage of generous insulation is that it works in winter, of course, but also ensures excellent free thermal comfort* in summer . Isn't life beautiful? 8)

* By this I mean without energy consumption.

I summarize Grandpa Claude's idea:

Put as much insulation as possible.

If you have good wall insulation, a minimum anyway, rather over-insulate the walls from the outside, more than €30, for example, invest them in solar and thermal panels, the consumption delta , would be more than offset by the cost of the energy produced.

We are not saying not to insulate the walls, but if you already have 15cm, for example, of wall insulation, it is better to invest in energy production.

It is a compromise between loss and production.

By insulating from the outside, if we already have a minimum, in heat, in cold, how much gain is that? 5%, 10%, 20%?

20% of 1500€ (heating), gives you 300€.

100 years to reach €30....

Yes, provided you manage the ventilation well, because I often see skylights wide open in the middle of a dodger. Image
