foam insulation faster that you can put more foam in place.
Silastic works but if the foam is brittle, the next time round is a disaster.
My cats got to like climbing the med density blue foam I used on the door
(I figured it needed to be rugged as well as insualting or it would end up all over the house)
after a while its insualting properties improved as it got hairy from the chunks the cats were
pulling out for fun
