ᐅ Experiences with calcium silicate boards?

I want to use calcium silicate boards for interior wall insulation because I can get them very cheaply from a colleague. However, I would like to learn more about the boards beforehand. Are they any good? What experiences have you had?

Calcium silicate boards are well suited for interior insulation because they are moisture-adaptive, meaning they can absorb and release moisture (e.g., condensation from the wall) without being damaged.

However, it is essential to check the manufacturer’s website for information on how to properly install the boards.

I have used calcium silicate boards for insulation myself. They were recommended to me at the time by my general contractor. I didn’t really question it back then, but I can say after 10 years that I have no negative experience with the material.

I am also familiar with these boards, and so far we have not had any negative experiences with them. It is important that they can absorb moisture and then release it again.

I have not had any negative experiences with the calcium silicate boards either. Due to their high pH value, mold growth is not possible. We used them to insulate an old half-timbered house, as external insulation was not an option in this case.

Hello,
I find these panels great, especially for preventing mold. If mold appears, cover all surfaces with these panels. Otherwise, mold will show up at the seams. Of course, the cause of the mold must be addressed first; otherwise, this won’t help much.

They’re not very expensive, and I got these panels at 25 mm (1 inch) thickness for about 20 CHF.

Best regards
