Buying Guide

Match underlayment to floor type

Choose materials designed for your finish—underlayments labeled for LVP, laminate, or hardwood ensure compatible cushioning, load distribution, and warranty compliance

Check moisture and waterproof features

For basements or wet areas, prefer products with integrated moisture barriers or waterproof membranes to protect subfloors and flooring from vapor and liquid intrusion

Prioritize sound control if needed

If noise reduction is important, look for underlayments specifically marketed for sound dampening or with proven impact insulation values to reduce footfall and airborne noise

Consider roll size and coverage

Select roll dimensions and square-foot coverage that match your project to minimize seams and waste—larger rolls reduce seams but may be heavier to handle

Evaluate durability and installation type

Assess features like tear resistance, anti-fracture membranes, and whether the product requires adhesives or is loose-laid to match your installation skill and subfloor conditions
