Underlay sandwich system
A very effective method of leveling the substrate is the Floorfixx sandwich system - it consists directly of two layers of MDF boards, the bottom with the substrate (XPS foam or perforated polyethylene, depending on the type of substrate). Everything is in one piece, there is no need to lay each layer separately, which greatly speeds up the installation - it is the most time-saving solution on the market today.
Advantages of Floorfixx underlays:
- They also work where it is not possible to use conventional leveling (for example for raised floors).
- Installation is very quick and easy, there is no need to lay each layer separately.
- The Floorfixx sandwich system meets load classes 31-34 (depending on the type), so it is also suitable for heavily loaded industrial spaces.
- Thanks to several layers, it has good sound and thermal insulation properties.
