Hello everyone,
During the renovation of our older building, we had all the floors removed to install an underfloor heating system. Since the house consists of two parts with different concrete slab thicknesses, the heating engineer had to do quite a bit of calculation. Various doors (front door, 2 patio doors) and their heights needed to be taken into account.
After determining the heights, the new windows and doors were installed. It turned out that the window installer made a one-centimeter mistake during installation. We didn’t think much of it at first, but when the height was checked again against the doors with a measuring tape, it was discovered that there are several height differences in the ceiling. This means we are now facing the problem that, with the underfloor heating height plus the tile thickness, the doors might no longer open properly.
Now the question is, the heating engineer suggests switching to liquid screed, since you can save about 1 centimeter (0.4 inches) there. We had already planned for only 4.5cm (1.8 inches) with concrete screed, but now even less? Can liquid screed withstand the same load at a reduced thickness? I am also considering shortening the system panel from 35mm (1.4 inches) by 5 or 10mm (0.2 or 0.4 inches). I’m not really sure what is possible or what would be better.
Good luck
