Hi, I am replacing my old uPVC front door with a new composite door with a new frame. The old frame just sits straight on the floor but the new frame is different. I'm not sure if the new frame needs to sit ontop of a separate sill, or whether I can sit it directly onto the floor like the old one. It looks as though it's been manufactured with a integral, low profile, aluminium threshold.
I hope it doesn't need an external sill as I don't have much vertical height to play with, perhaps 20mm if absolutely needed....

Thanks
