Internal door separating house from conservatory

[con1_uk]

Hi,

I know we should have external doors between the house and the conservatory but at the time we went for internal bi folds which during the winter months let a lot of droughts in.

Are there any good solid internal bi-folds or similar solutions to alleviate this issue please?

Or do I just get external ones fitted?

If you want to maximize cold retention then fit external grade doors, treat the conservatory as if open to the elements.
