Frequently Asked Questions
Q: What flooring types is this underlayment compatible with?
A: This SucceBuy floor underlayment is designed to work with a wide range of floating floor types, including vinyl plank (LVP), laminate, engineered wood, and hardwood floors. Its versatile construction provides cushioning, noise dampening, and moisture protection for all of these floor types.
Q: Does this underlayment include a built-in vapor barrier?
A: Yes! This underlayment features an integrated PE (polyethylene) film that acts as a vapor barrier, protecting your subfloor and flooring from moisture, humidity, and vapor transmission — helping to prevent warping, swelling, and deformation over time.
Q: Is this underlayment easy to install without professional help?
A: Absolutely. The underlayment rolls out easily and includes pre-taped seams for a secure, gap-free fit. It can be cut with standard scissors or a utility knife to fit any room shape or size. No specialized tools or professional installation experience is needed.
Q: What is the difference between the 2.0mm and 3mm options?
A: The 3mm version (100 sq. ft per roll) uses a Recycled Fiber + PE Film construction, providing excellent soundproofing and cushioning. The 2.0mm option (available as a 6-pack covering 600 sq. ft) uses an EPE + PE Lamination construction, making it a great choice for thinner profile requirements or large-area projects where cost efficiency matters.
Q: How do I calculate how many rolls I need?
A: Each roll covers 100 sq. ft (approximately 9.3 m²). Measure the total square footage of the room(s) you plan to install, then divide by 100 to determine the number of rolls needed. We recommend adding 10% extra to account for cuts and waste.
