I will lay reflecta boards in an area along a window sliding door. The reflector boards are 13mm high.
For the remaining part of the floor, I plan to lay 13mm floor gypsum to achieve the same level as the reflecta boards.
Is there a better material choice than floor gypsum?
The function of the floor gypsum is only to ensure the entire floor is at the same level.

Anyone have any tips?
Is it possible to get 13mm EPS?
Feels like anything is better than floor gypsum.

Really a surge of ideas 
The new plan is now to lay 12mm particle board to reach the same level as the reflektaskivorna. The reflektaskivorna are 12.5 mm to be exact.
There shouldn't be any issue with a 0.5 mm difference between the areas, right?
