Hi what's the procedure when replacing old double glazed windows in a traditional bungalow which has roughcast walls in UK. Or is this method just for new-builds?

You applied the expanding foam tape before the sealing membrane 😅

Would you do it any differently if installting aluminium windows into a timber frame?
