UltraSeal Underlayment - Moisture Protection & Comfort for Floating Floors

UltraSeal Underlayment is a reliable, all-purpose flooring underlayment designed to improve the performance and comfort of floating floors. Built with integrated moisture protection and sound-dampening properties, it creates a smooth, stable foundation that helps your laminate or vinyl plank floor look better and last longer.

Built for Floating Floor Installations

UltraSeal Underlayment is installed directly over concrete or wood subfloors before laying floating laminate or vinyl plank flooring. It helps even out minor subfloor imperfections while acting as a protective barrier between the subfloor and your finished floor.

Dependable Performance You Can Count On

This underlayment includes a built-in vapor barrier that helps protect flooring from moisture migration, especially important over concrete slabs. Its closed-cell foam construction adds durability, reduces wear from subfloor friction, and contributes to a quieter, more comfortable floor underfoot.

Easy, Installer-Friendly Experience

Designed for fast roll-out installation, UltraSeal is lightweight and easy to cut, position, and secure. The material lies flat without curling, helping installers maintain consistent seams and minimize installation time, which is ideal for both DIY homeowners and professionals.
