Expanding foam around the top of an external door?

Hi, we just had a new front door fitted. There was a draft coming through the top and i suspected they hadn't filled the gap with foam. At first the installer said they must have, but when i asked them to remove the plastic covering, sure enough just a gap. Now they want to come back and fill the gap with silicone. My question is, should i insist that they use expanding foam as surely silicone won't be insulating? He said expanding foam might be messy and not needed for a small gap. The gap is about half an inch. He is coming back later, so a quick response is hugely appreciated! <UPDATE: he came back and must have decided for himself to use foam, so i didnt have to argue the case. Thank you Welsh&Hunter for your quick reply, that was v helpful>
