Can i use Thermaline for a fire recess?

[fearofthedark]

In the process of building a recess for a pither stove. I am at the stage of needing plasterboard. I was considering using plasterboard with better thermal properties for the back board at the rear of the recess as this is the outer wall.

Is Gyproc ThermaLine Plus suitable or would i have to use a Gyproc Fireline board?

Thermaline is for insulating walls the fireline would be better, although there are heat resistant renders/plasters you could also use

The pither stove is far enough from the recess walls to permit standard gyproc board rather than fireline. However if there is not major increase in cost i will get the fireline.

The intent for having the thermaline was to prevent heat loss on the outwear wall (rear recess) . probably would not make much difference. Just thought it should be done as i have the opportunity. the thermaline is not for the sides of the recess.

It just so happens I've been on their website looking at the board range today, I think the 48mm board has a 12.5mm board to withstand flames for 45mins. here's a link to gyproc's board range.
