Injectable Foam Insulation for flat roof celling

[relwoh]

Hi I am looking to get some injectable foam insulation for a flat roof celling that has some spaces in the existing insulation. I am aware that you can buy big kits that you might use to fill up large spaces like a wall or something. However I just need a small amount for some gaps in the insulation not a huge kit.

My question is this can you buy smaller amounts of injectable foam insulation like in a tin or something?

I don't think no more gaps filler is suitable is it. Any suggestions please?

Wont that crack the plaster board when it expands?

No it wont.
Only thing you need to be aware of is any electrical connections, downlights etc.

I would rather use injectable cellulose insulation (its a power that blows in) but I don't know i where I can get an injector machine or pay someone to do it. Anyone know
