Plate behind woodburning stove

[David]

Dear All

We had a woodburning stove installed around three years ago and very nice it is too. Unfortunately, the fireboard behind the stove won't behave itself (cracks in the joins etc) and we want to put some sort of metal plate between the stove and the fireboard.

There's about two inches of clearance behind the stove and the fireboard has vermiculite behind it.

Does anyone have experience of this or know what sort of plate we would use or whether such plates even have a name?

Yrs in ignorance

well if it was an open fire it would be a fireback..

Its a very high stress area. Ours get white hot on open fires and usually crack.

That's cast iron.

you could put up almost anything (metal), but whatever you put up will buckle.

fireboard is best. There should not BE any joins in it..

Is the fireboard in two pieces ("cracks in joins") for ease of fitting? - I can't see how a metal plate in two pieces is going to help with the increased thermal expansion. Are you aware that you can get high temperature silicone sealant that may solve your problem? Also, but I doubt this will be relevant , there are two sorts of "cement" based fireboard with two very different prices. The cheap one is to provide fire protection - a one off containment of a fire and the second for use round fires designed to withstand repeated heating/cooling

Thanks for this.

I don't really want to go with taking out the board and fitting a better board owing to the vermiculite and mess etc. What I have found in the meantime is a big cast iron panel

've seen these somewhere and they look quite nice. GBP130 + 20 delivery.

This would fit behind the woodburner in the fireplace and could be fixed over the damaged fireboard. I'd probably do it the same black as the stove and it would have a border of undamaged fireboard around it.
