hi customer has solidly fixed 8x4 sheets of kingspan in a small building an d. he wants me to board and skim it,is the best way do it fix the plasterboards to the kingspan,by using lats and screw the board onto them,or is there a adhesive that would be strong enough to stick the boards onto the kingspan,im thinking best way is to screw wood lats ,then screw the boards to the lats,thanx for any advice offered guys
