What's the point of a sill? New door order question

[EggMella]

I'm just about to order a new door and one of the questions I need to answer is what sort of sill I want.... a choice of 3 different sizes or none at all.

I'm guessing a sill is there to take the water away from the door joints or something but my question is do I need one? The door sits in a 50cm alcove semi-shielded from the outside, the existing wooden door has a sill. Do I need one for my new door?

cheers

sounds like the smallest sill will be fine for you in this situation. the biggest ones (like on some upvc doors) can be a bit of a pain to step over

Opt for a low aluminium threshold cill and not a std plastic cill. they may charge you extra for it as they are expensive but well worth the money.

ok - so I do need a cill but I can go for the smallest they have I'm also trying to get the door as close to the floorline as possible and they have sent me their "level access threshold detail"

Can anyone give me general advice about fitting this door, using a "level access threshold detail" and installing the cill itself as it looks like they are advocating a concrete cill for this purpose.

The low aluminium threshold cills are already screwed to the bottom of the door frame.
