Yes, tiler tested all floors, moisture was low, he said laminate was ok to go down on it

How do I find out the flow temperature? Moisture reading was low

Surely a manufacturing issue if that's the case? I can separate the boards in places.

Euro home 12 mm AC4 or AC5 rated I believe. Seemed to be good enough stuff at the time.

If it is skirting that has been installed too tight, are the boards likely to be ok or because they are raised are they likely to be damaged now?

New build house, UFH is running at 20.5 degrees. Sand cement screed subfloor. Underlay is the orange perforated.

Could there have been moisture damage when it was stored in a warehouse? The floor only gets a light mop with very little water, it's only been down a year at this point. Underlay was put in even, there's numerous boards throughout with the same issue.

The laminate floor in our hall has edges protruding up. Expansion gaps of at least 12mm left around the perimeter of the walls. We have under floor heating but I've checked and this is compatible. Subfloor is level and we have used an underlay. Flooring rep is calling next week but I'd like as many opinions as possible. Many thanks
