If I make a loft hatch out of 3inch wide kingspan
sandwiched between plywood,
how can I do the hinges and edges
such that it is draughtproof?

How about 'with a draftproof seal'?

Instead of hinges, just let it sit on a batten "ledge" inside the frame.
Then you can put ordinary sticky backed foam draught strip on the top face
of the ledge. You don't need plywood both sides (unless you are planning to
put it down and walk on it). Hatches on hinges always get in the way of
something which you want to put in or take out. With a free hatch you just
lift and slide it sideways. That's assuming you use steps for access, not a
built-in loft ladder. With a loft ladder it's usually easier to hinge it to
"drop", held up with a "push to lock, push to release" catch. Not so easy to
draught-proof.

After making the opening and hinging the hatch I climbed into the loft and got
may wife to remove the ladder and close the hatch (having picked a day when not
in doghouse). Then fitted 1/2" batten all round the frame perimeter with
cardboard spacer just touching the top of the hatch. With the hatch open, glued
'P' shaped plastic draught excluder (B&Q) to bottom of battens.
Alternative method would have been to cut battens to size and glue excluder
strip then glue/screw battens to frame above hatch.
Obviously lost 1" of opening in length and width.

We've got to change a useless Wavin plastics (OSMA) type door hatch
bloody thing has warped and the **** poor effort they made at sealing is
useless you can see the pound notes whizzing up there!...
