Will double glazed stable door be a problem?

[Selfbuildsarah]

We are planning to be triple glazed throughout our new build using good quality windows. I would like a stable door at the back of the house onto the garden but they only make a double glazed version (no idea why).

The door will be off the small utility room. How much might it affect the thermal efficiency?

Maybe weight? Our doors are also double glazed, I chose to go double with Krypton gas fill instead of Argon. Brought the whole door U value down to 1.0. Really good door otherwise was 1.2 with Argon. think triple glazed was something like 0.8 for a door. (from memory, exact figures may be a little different - but not much). You could go vacuum double glazed for better than triple, but cost starts to get a bit silly.
