In the process of making a insulated solid oak door, what's the best insulation to use in it. I don't have any ceramic fiber left so my options are . . Kingspan, rockwool , loftroll or loose Vermi. What's gonna be my best bet? I'm gonna have about 70mm of insulation in the door, photos to follow when it's complete!
Cheers
Keith

Hi Keith!
I'd say loose Vermiculite, then Rockwool (preferably Fire Blanket), loftroll, but i'd not use any of the Insulation Board variants. They can start to blow and colour at around 50degrees.
And they'd be held within a sheet metal section bolted to the oak of the door too.
Can wait to see your door!

Thats right Kip!
All insulation is, is a method of trapping air which gets warmed up.

Hope you expect that bit of oak nearest to the fire to be a sacrificial part Keith?
It'll get a bit charred over time...

had a few hours spare today so have made a go at making the door. i was given a length of oak floor board from the generous chap at the reclamation yard I bought my bricks from. not sure what t do with the cavity, I may scavenge some vermiculite from around the build or leave empty. I will make a channel 0n the circumference of the inner part and put fire rope around to make a tight seal.attaching it with what im not sure yet.heres a piccy  20131123_143344 by dave-2, on Flickr |

 20131123_143528 by dave-2, on Flickr actually maybe I could get thick fire rope and trap it between the two pieces leaving some to protrude ??if you know what I mean. |

danno . . . yea i was worried about this, i think i would cry if it went up in flames, there was some work went into that door! what i'm thinking is getting a piece of thin stainless steel cut then self tapper screw it to the inside face of the door to protect the wood from the direct heat. would this be adequate to stop it going up in flames? at baking temps i'm not too worried i'm more concerned about when i seal it up after a full heat pizza firing if it could take the heat!

nice fitting door kip! yes i would try and incorporate a stove rope if i were you to get a better seal! i know you have cut both your doors now but if you have some more oak you could make the outside door the size of your outside arch then screw it to your inside one so the outside one closes up against your reveal thus giving a good seal. if that make sense!
