Weatherstripping at Bottom of Door

In our new house, there is about 1/2" gap below the door that is allowing a draft to come in. What would be better - a door bottom with synthetic fibres like this (Door Bottom with Synthetic Fibres, White | Canadian Tire) or a sweep?

Thanks!

It would help if we could see the door and threshold. Newer doors have adjustable thresholds and door bottom gaskets. Older doors often had a wooden threshold (non-adjustable) or aluminum blub seal thresholds. Hard to give advice blindly. But a 1/2" gap obviously isn't normal and needs something! Just can't say what without a picture. If you can upload one that would help.

Here are the pictures. I appreciate your thoughts! The gap is about 1/2".

Thanks!

How about a pic of the threshold with the door open.

You probably want a door bottom with a bulb weatherstrip, kind of like this one.

There are various styles. But that's the type you want, not a sweep.

I see that's a steel door... they usually have grooves on the bottom to accept a door bottom weatherstrip. If you knew the exact measurements of those grooves, you could probably get a door bottom like this that would work.

Thanks XSleeper!

Can you elaborate on why you think the bulb weatherstrip is the right choice over one with synthetic fibres?

Also, why do you say that the sweep is not right? Too big of a gap?

Interior mounted sweeps (I can see the holes from the old one) eventually get tired and don't seal tightly. At first they work fine, but as the fin (or bristles) bend back constantly, they lose the tension that formerly held them snug. I could see a nice bristle sweep working better than a rubber fin, if it barely contacted the threshold. But they aren't that great at stopping air.

A bulb works better at sealing, especially when the door has been bevelled, because the bulb wants to spring upward into the door when it's closed, and wants to return to it's normal shape when open. A bulb will always maintain a nice even upward pressure on the bottom of the door.

Door bottoms, like I linked to at the end of the last post, have both bulbs and fins on the bottom, usually multiple bulbs and fins.
