Our underlayment is made out of cutting-edge IXPE (Irradiated Cross-Linked PolyEthelene), the newest advance in foam technology
IXPE is a closed-cell foam that is 100% waterproof, and impervious to mildew, mold, rot, and bacteria
While cork under-layment may resist moisture , in a flood or leaky appliance scenario where significant amounts of water are exposed to the floor for prolonged periods, there is the chance for mold, mildew, and rot to set in.
Good Thermal Insulation
Due to the closed-cell nature of IXPE, it is an excellent insulator and is used in many instances for its insulating properties.
Improved sound control
While sound performance is a complicated topic, our 1.5 mm IXPE has a IIC (Impact Insulation Class) rating of 59-60, compared to 1.5 mm cork at 53-55. IIC specifically relates to impact related sounds.
Compared to cork, IXPE provides superior sound performance.
IXPE is used in the automotive industry to keep the cabin insulated, both in terms of sound and temperature
