DeciBlok MC is the vapor-impermeable version of DeciBlok that has an attached foil film. It is a subfloor surface liner designed to be installed under 6.5 mm-plus-thick LVT/LVP, WPC/SPC core, laminate, engineered, or solid hardwood floor, or carpet tile with any style backing.

The product rolls out onto the subfloor, creating a sound and moisture barrier while also becoming a “clean-start” liner between the subfloor and finished floor. It levels out any minor irregularities and can be installed on, above, or below grade.
