Dob and Dab Plasterboard Foam

[bobsy12]

I've got dob and dab plasterboard going into the attic space.

I understand its best to seal the gap between the breeze blocks and plasterboard to prevent draughts getting in behind the plasterboard and into the house.

I've heard it best to avoid normal foam as it expands too much and could warp the plasterboard.

Some say to go for low expansion and some say to go for non expansion foam.

Can anyone recommend the best foam filler and where to buy from?

Why not use a continuous line of D&D adhesive at the bottom and at the top? This will also fulfill fire regs so i believe.

This method will prevent any movement of air behind the boards...
