I found some recommendations for screwing ply to the top of the inner leaf (I think that some 100mm drywall screws would be fine without rawlplugs), and then gripfix the timber sill down to the ply?
What did you think of sticking the sill directly down to the thermalites using Caberfix or Sticks Like#
What is that lip that protrudes along the top/back of timber sills? What does it do?
Thank you.
