Fire-rated partition wall in sunroom

[Murdoc12]

hello

Does anyone know more about how to achieve EI60?

I'm wondering if fire-resistant plasterboard can be used in an unheated and not fully insulated conservatory.

The alternative is wood and in that case OSB. Can a simple framed wall without insulation be built to achieve the 60-minute requirement? It's probably double boards on each side, but at what thickness?

Regards

I would also have built with minerit, or bricked the wall.

Interesting.
I guess you can manage with one board on each side?

Looks like double 12mm boards for 60 minutes.

EDIT: I see that this can escalate in price with about 12 boards for a wall. It should be significantly cheaper with OSB, I think.

I wonder if fire-resistant gypsum can be used in a conservatory that is unheated and not fully insulated.

The alternative is wood and possibly OSB. Can one build a simple stud wall without insulation and meet the 60-minute requirement? It's probably double boards on each side, but in what thickness?

Hello! How did you solve it? Can you share the exact layers from the inside to the outside?
