I've also gone for a lightweight door. Using it one handed is a big advantage. Mine weighs 1.5 Kgs made from hardwood with a 12mm insulating panel attached with 3/16" stainless steel bolts. Often use it placed half way in the entry.

How thick is your aluminium sheet?? I'm looking at making a lightweight door with a similar design, i'll keep everyone posted on how that goes!

Cheers!

My door is made in the similar manner as yours. It is made of aluminum, two inches thick and insulated with 2" spun ceramic board, but I get a lot of heat transfer through it. It gets so hot that I need oven mits to handle the door. It is made in two sections, one "tub" section that houses the insulation and a second "backer" section with the handle. These two are bolted together. I am thinking of adding ceramic rope between the two sections to cut down on the heat transfer.

The sheet is 1mm thick.
Ive clocked the door and it only gets to 20c above ambient on the outside with the oven at 300c.
There will be some transfer of heat around the edges to the outside.

Its probably the bolts transferring the heat.

I did a second apprenticeship in boiler making long after Id finished my bricklaying apprenticeship.

In the boiler making courses we learnt lots on heat transfer, it doesnt take much to get the heat moving.

The larger the bolt of course the greater the heat transfer.

You couldnt glue the two together with something like this?

Agree re size of bolts. That's why I used 3/16" You should also use stainless, zinc is toxic.
