Bison mat

[Joel.I.A]

Hi,

Does anyone here know what a Bisonmatta is? I spoke with a bricklayer who said this can be good for insulation when pouring floors.

Best regards,
Joel

Maybe similar to Elefantmatta, a very hard Rockwool.

Where in the casting are you going to have it if so.

On the slab, under an overfloor of 5cm concrete. That is, embedded between the base slab and the inner floor.

The downside of Elefantmatta is that it absorbs moisture/water and then provides "no" insulation.

What is recommended today is foam board with closed cells (polystyrene/ground board) that does not absorb moisture, has high load-bearing capacity, and offers good insulation.

Now, Bisonmatta might be something different.

According to Google, tram-safe fiberglass-reinforced plastic mat. Didn't find any images, though, with the first quick search.

EPS - i.e., polystyrene, also becomes water-saturated, at which point its insulation value plummets.

Strange that the construction industry says the opposite, but now there are 2 different types of "styrofoam", the ground board with closed cells does not absorb water.

If anyone has a different opinion, please provide a link to a report or a data sheet.

Exactly, but who sells it and what are its properties...

Bison exists as a brand, but at their retailers, I only find different kinds of vapor barriers and wind barriers.

Water-saturated styrofoam sounds strange, it has been used as a floatation element in floating docks and all sorts of other applications for as long as I can remember. It shouldn't work if it can become water-saturated.

"Regular" styrofoam absorbs little water but not ground plate.
