Sas,
Another reason screwing is better than dabbing is down to the movement of air and heat loss. When a wall is dabbed it is not tight against the wall/insulation. Therefore there is a possibility of air movement behind the slab. Where there is air movement there is a risk of thermal looping (hot air rising, pulling cold air to replace it) and heat loss.
