I do not recall ever designing a home with double main entry doors. I feel it is most times inappropriate for a main public entry for home. If you have big furniture, bring it into the house another way.

I have known one person with double entry doors. They were a nightmare. They only used one door (as everyone who has 2 doors does), but the doors didn't align perfectly so sometimes they wouldn't latch correctly. Their cat would get out all the time because the door would just randomly open. Seemed more trouble than it's worth to put in a door you'd never use. And they lived in socal.

(not a pro) I think double doors look very pretty, but I agree with chispa in preferring a single + sidelights.

Do some research into securing double doors, e.g.:

• Double doors are vulnerable where the two doors come together in the middle. There is generally only an overlap of molding where the doors meet. If the doors open into the room, this weak spot makes them extremely easy to kick in.
• Use a three-point locking system. This is very important for double French doors. That’s because the bolt of the lock doesn’t extend into the solid door frame, it extends into another door, and that door is just not as strong as the door frame. Three-point locking systems include metal rods that extend from the door up into the top of the door frame and down into the floor. Combined with the deadbolt, these rods make the doors much stronger than the deadbolt alone.

I grew up in a house in Calgary Canada with double front doors and I do not recall my parents ever complaining about them not functioning well and they certainly kept the cold out.Maybe like so many things the dors are just not made like they used to be. I think our doors were maybe 60 yrs old .

I happen to love a double door in the right home, and where it is well suited to the architecture. There is no climate issue. You open one side, unless a reason to open both. Like a piano coming in. : )

I had double doors in my previous house. They were gorgeous, suited the house well, and I loved them. They were a statement. They were wood with glass inserts --the bulk of the doors were wood, unlike your pic. I never had any problem with climate affecting the function of the doors, they open and closed perfectly and kept the cold out just fine. Like anything, installation is key -- the highest quality door in the world isn't going to function well if the installation is poor. Just like windows.

The maintenance it did require was re-finishing/re-sealing every few years because it was wood. No big deal, they're just doors, and as long kept up with it wasn't anything that was a headache. And yes it was nice for getting big things into the house!

I had double doors in my last house (NC). They weren't horrible but they certainly don't seal as well as single doors. Everyone has different standards for door sealing and different expectations.

The best door uses 7 points to latch. Virtually unheard of in the US. In an area where 7 point latches are common, it would be ludicrous to do a double door.

In a decently harsh Indiana climate, triple point doors should probably be used. I don't think a double door would make sense there.

Controlling air infiltration is literally the easiest way to keep a house comfortable and lower HVAC costs.

Next consideration - and this was big for us - there is no way to control the forced opening of a double door as well as a single door. Given that it is the most common mechanism of entry by criminals, it should be a consideration.

Lastly - aren't they a bit pretentious?

I had double doors for 20 years, no crazy maintenance. I have another set in my new home. Security is a concern so we had a ”door club” installed. you could not readily kick in the door. One for each door.

If your home is going to get broken into, your rinky dink backdoor is the first choice followed by a brick through your sliders. secure the rear of your home. best of luck w your new home.

We’ve had Thermatru double entry doors for over 20 years with no issues whatsoever. They are very practical for us and are the only straight run into the house when moving furniture, appliances, etc.

We have double doors and sidelights. They are beautiful. They were here when we bought the house so we just had them painted. They’re a little 80’s but with leaded glass inserts would not replace them. We’re in California
