When Air Foam goes bad

Air foam is insulation that gets pumped into the walls - it goes in as a dense liquid, foams up, fills the wall cavity and does its insulationy thing. Hehe. It also does this if you've got a special combination of factors in play ...

I would have taken a photo of the inside of the cabinet that had the drawers in, but I got chased out of the kitchen so all I got was the drawers. The chasing also resulted in the fuzzy pic quality sorry. Who knew that a highly amused Ginger leaping around in the rapidly expanding (where it shouldn't be) insulation brandishing a camera wouldn't be appreciated?

(Fantastic product by the way - completely not their fault that we have shite gib in the kitchen)
