Insulating an oven - what to use?

[Minxy]

I know there was a thread on here about an oven not being great and some people suggested putting insulation round it, can anyone tell me what insulation type I'd need as I'd like to do mine and don't want to end up with an indoor bonfire!

Would slabs of rockwool be suitable?

I doubt it's rated high enough temperature wise

Have it wrapped around my wood burner.
This is from the manufacturers data sheet.

ROCKWOOL stone wool fibres can withstand more than 1000°C without melting, whereas the binding agent is lost at temperatures in excess of 250°C. When the temperature rises above 250°C, the binder will evaporate in the zone which is exposed to 250°C or more. But the fibres will remain intact as their inbuilt cohesiveness and layering will keep the fibres together, ensuring that the material will retain its rigidity and protect the material beneath it from being affected by the fire.

Since mineral fibres are highly resistant to temperature variations, ROCKWOOL mineral wool can be used under conditions of very high temperature, provided that it is installed in such a way that mechanical stress will not alter its shape when the binder evaporates.

Hi.Did this on my Moho 3 years ago.If you look online you can find Ceramic pizza oven insulation.It comes in a roll of what appears to be flame proof Foil.Sadly can’t remember the name.No issues with it at all.

That's the issue though, a MH isn't 'static' so when the binder evaporates the moving around of the vehicle could easily cause the insulation to be dislodged, last thing you want is a 'fire' in your MH due to the insulation causing issues! We've had a 5ft blowtorch in ours (seriously!) so you can take it from me that you do NOT want to experience it.

This thread reminded me of when I bought my first MH brand new, a few trips out at a rally we decided to do some roast spuds for everyone, in they went and set the timer, went back to check and the oven gas was still flat out and the rack bars at the back over the flame were glowing dull red, obviously the thermostate was not working and regulating the gas.

When I got home Swifts sent a Technician to have a look and repair it, when we got the oven out the thermostate probe was on the outside of the insulation so was never going to work, it must have come from the manufacturer like it and Swift didn't notice when they installed it.

Our racks do that too. We've only had the MH 4 months.
