Are dutch doors less energy efficient?

You know, the doors that open separately at the top and bottom. Does this ability mean they lose a little more heat than standard doors? I would imagine they do - they have a crack straight through the middle. I really like them though, so can someone clear this up?

Yes, they are slightly less energy efficient. It really is negligible though, you'd struggle to notice a difference unless one of the parts of the door has been sanded/planed down too much.

As the above poster touched on, a Dutch door's energy rating comes almost exclusively down to the quality of the finish in the middle. The two doors need to be as tightly fitting as possible, even to the point where they're a little stiff to open. If they open extremely easily it can be a sign of a gap that's too large. Many dutch doors have small wooden panels that stick out now though, which attempt to cover these gaps for insulation. You need to make sure any Dutch door you buy has one of these.

Dutch doors are actually powerful doors because they have multi-purpose capabilities and have multiple benefits that can help reduce utilities and prevent future costs.  Greenmatch discusses about the powerfulness of the UPVC Dutch or also known as UPVC Stable doors--> http://www.greenmatch.co.uk/upvc-doors/upvc-stable-doors

While Dutch doors made with wood can have R-values as low as R-1, more energy efficient materials and additions can boost the door's R-value to R-5 or higher. Wood, fibreglass, or vinyl exterior doors tend to insulate well. Homeowners who choose to incorporate a glass panel on the top portion of their Dutch door may want to also add insulated panes and low-e coatings to insulate their home and lower overall energy consumption.

Because their top or bottom halves can open independently, exterior Dutch doors can be an excellent to increase airflow in your home during the warmer months. This increased airflow will create a more energy efficient home, lowering energy bills for expensive air conditioning.
