Concrete floor thermal bridging

[JamieB3009]

Hello,

After some advice. I have a house with ufh downstairs and a liquid screed. I saw it being put in and there was 150mm insulation under the screed with 25mm perimeter insulation around edges. Where my floor meets front door, bufolds etc., it feels much colder and gradually gets back to warm as you move your foot away from the edge. I assume this is cold bridging. I don't appear to have any condensation on the door frames etc. (Composite front door and aluminium bifolds) but is there anything I should be worried about that could be going on under the floor finish? I.e. would this do any damage to screed over long term etc? Thabks

Are your doors on the outer leaf ? If so won’t have fit across the cavity.
