XF + MW System
XeroFlor + Mineral Wool
The Hydrolight Built-Up
The XF + MW built-up system is an upgraded alternative to the XF + GM lightweight built-up system. Using mineral wool instead of moisture mat improves the water retention capacity without substantially increasing the weight of the assembly. Excellent water retention to weight ratio combined with all the other features makes this assembly suitable for almost any type of project.
