Insulation: hemp concrete or cellulose wadding

[airsp]

Hello

I plan to do a medical practice in an old garage.
This one is on the ground floor of an old stone building located in the south of France.
The walls are stone, thickness 50cm.
Solar gains: none

I do not know how to isolate this room.
I hesitate between wadding or lime / hemp.

I aim for a good thermal comfort since the patients will be bare.

I'm afraid that lime hemp is not enough insulation.

What to put as a wall covering: lime plaster or wood paneling?
As heating?

Thanks for your help

This one is on the ground floor of an old stone building located in the south of France.
The walls are stone, thickness 50cm.

therefore the walls are in good contact with the ground much more than with the outside and therefore they remain at the average soil temperature over a year is 13 ° C in the south of France.
In addition the thick walls have a strong inertia and average variations of T over several days between day and night.
You will never get very cold or very hot, mini 10 13 ° C without heating and max 20 ° C approx !!

This is much better than the newer buildings, about 1950 years and after, often poorly insulated and low inertia.

So you insulate as you want, but without insulation and more, it is livable by heating enough, rather wood, automatic pellets or logs, to be ecological, as before, without being too cold or too much expense.

In my opinion the local taxes and home, 2 will be 3 times the price of heating, as for me!

the problem is different from a dwelling:
- 13 degrees, naked, it is not possible; you have to aim 23 / 24 degrees
-the local is not inhabited often (no or little weekend, night ...) so it requires reactive heating rather than wanting to heat the stones.
- unfortunately, 20m2 does not make much for a pellet boiler; I thought a floor heating, which together be ideal in terms of thermal comfort; but implement this system for 20m2!

unfortunately, 20m2

Very small for a medical office ??
I thought it was a real garage mechanic !!

But it is almost inevitable to heat the walls a little with insulation, except for a few hours.
The thermal constants of the usual insulators of air are those of the air about, fast.
You put what you want inside insulation.
Small pellet stoves are fast and easy and so good for heating up quickly, 1 stove at 2 KW max with insulation and max 4KW without insulation at all, and especially with circulator or air blower to quickly have hot air on the clients, without having the warm walls.
With the insulation you have better to have a doubling with low inertia, so thin wood, like paneling, to heat it quickly for a short time.

Avoid a PAC, which will be proposed to you in a short time (easy solution), if you are not to continue the nuclear and a Fukushima in France !!

The tiny pellet stove is also easy.

Hi, you can simply make a wall doubling, with a fiber or wool type insulation of what you prefer.

a radiant heater can be a good instant option.

[dedeleco]

a radiant heater

almost always electric, is ideal for needing to develop nuclear reactors until the next Fukushima in France, probably in the Rhone Valley, the most nuclearized region in the world!

[antoinet111]

you tell him to put a wood stove !!!!

IN A BUILDING ! Do you do it on purpose?


you think the office will allow him to make a conduit ???

instead of taking out your science, read a little better ....
Fun.

[airsp]

What do you think of floor heating?

[dedeleco]

There are stoves so sucker very simple!

And when there is a disaster removing our electricity, there will be more way to heat with radiant or PACs!

Also be careful to keep a max of fireplaces !!

[antoinet111]

the floor heating, it remains the top, especially barefoot.
on the other hand, it often requires inertia.
So warm up the room in advance.

would you turn to what type of heating, or at least from which source of energy?
