Fire and moisture-resistant insulation?

[pelpet]

Now I'm out theorizing again, but is there any insulation that is both fire and moisture-proof?

Mineral wool and rock wool are considered fireproof, but they are sensitive to moisture. If moisture gets in, it doesn't dry out, and then it molds.

Cellular plastic and PU foam are completely moisture-proof, but not so good if it burns.

Sawdust can breathe out moisture but is quite poor as insulation, and what happens if it burns?

Ecowool breathes and burns about like wood. It states that you must build the construction airtight, even though it can be diffusion open. I don't know how good ecowool is as insulation though. Or what it costs.

I would argue that you are wrong regarding stone wool. It is definitely good as, for example, fire protection. But you write sensitive to moisture? This type of insulation is often placed between capillary-breaking layers and walls, floors & ground.

Here's what Rockwool writes in their brochure,
Moisture-resistant: ROCKWOOL stone wool is moisture and water-resistant. Even if ROCKWOOL stone wool looks wet when exposed to rain, it's only the outer few millimeters that are damp. The moisture dries out quickly. Moreover, ROCKWOOL stone wool is diffusion-open and allows water vapor to pass through the wool without condensing.

Was it that simple?

I have to look more into mineral wool then. I'm considering building a playhouse with a diffusion-open construction so that it can be kept unheated.

Do we believe what a producer writes in their advertisement?

Check out Casco Firefoam.

Of course, one should be skeptical of advertising. But in this case, I believe in a brand that has been around since 1936 and a product that has existed since the 1950s.

I would absolutely believe that TS can build their playhouse without having moisture problems depending on the insulation.

A tip for TS is to choose a construction from the manufacturer, for example http://www.rockwool.se/produkter/u/2011.construction/1542/

Edit: A question for TS is why aren't you checking with the different manufacturers?

I had thought that glass wool and stone wool were fairly equivalent in terms of moisture. Wrong input information then.

Foamglas is the only material that is both moisture-resistant and fireproof.

Used, among other things, as fire insulation, it insulates equally well under and above water. Inverted roofs, basements, etc.

This. An excellent product that meets most things except for a low price
