Insulate garage door and fill gaps at side

[TryAgain1]

I would like to insulate a bifurcated garage swing up (up and over) door. I have breathable roofing membrane, mineral wool, bits of 150mm kingspan block insulation and various glues.
Could I use very small screws to attach the breathable roofing membrane to the inside of the garage door, pin mineral wool (or kingspan) to the mineral wool then lap the membrane over on the other side? The door swings up so I don't want to add too much weight to the door mechanism.

I also want to seal around the side and top of the door frame as it is very gappy at the top a bit of at the side

Invest in some Soudal low-ex fixing foam. Glue the PIR to the door and use the same foam to fill any gaps around the frame.
