My Kingspanned ceiling has a gap or two (or a hundred), which
I could fill up nicely with expanding foam filler. Can anyone tell
me if it reacts with the Kingspan? I am worried that the solvent
in the filler might melt the Kingspan foam.

Thanks,

AFAIK, the release of the urethane foam from the can starts the
polymerisation reaction which is not reversible. The polyurethane foam
produced should be virtually identical to kingspan. I think KS is all PU.
So yes you should be okay.

It works fine. I did this in a couple of places when insulating my
workshop.

I taped over the gaps using the foil tape leaving a small hole for the
nozzle of the can at one end and another at the other to allow air to
escape.

A *small* squirt and job done. I do mean small though. Read the
Peter Parry canoe story in the FAQ.

Also, do wear gloves as this stuff sticks to the fingers for days.

For a ceiling, definitely cover the floor.

Once cured, you can remove excess from the surface with a utility
knife and tape over it if you want.

Stickier than extremely sticky stuff. How ever if you get to it with
vegetable oil whilst still fresh you can get most of it off. I wonder
if a thin smear of veg oil would act as a release agent and stop you
getting sticky in the first place?

You can buy HUGE cans with long pipes to ease the cost and effort of
installation. This is what I intend to use. google for "spray foam"

Thanks Andy, and everyone else who replied.

I have used it before for a different job. A blob fell in my
hair, and I thought "was was that" as I reached up and
rubbed it around my head a bit. Bad move!
