Resistance of direct underlayments used for wood floating floors to static loads

The article presents the results of tests aimed at measuring compressive stress corresponding to deformation of 0.5 mm in plastic mats used for construction of floating floors made of wood and wood derivatives. The tests were performed on rebonded polyurethane foam, cross-linked polyethylene and extruded polystyrene. The analysis of the results allowed to conclude that the static load resistance of these underlayments varies greatly. The best parameters were recorded for XPS mats. A positive link emerged between increase in its density and the measured parameter. A decrease in strength was found to follow the increase in mat thickness. Resistance of PE mats was significantly lower, but still acceptable. PU mats displayed the lowest static load resistance, failing test criteria.
