Description

CGC Fiberock® Underlayment is your reliable solution for durable and moisture-resistant subflooring. This 1/4-inch thick panel offers outstanding performance under hardwood, ceramic tile, vinyl, laminate, and carpet. Its fiber-reinforced construction resists swelling, warping, and indentation—making it perfect for both wet and dry areas of your home. Unlike wood-based underlayments, Fiberock contains no resins, adhesives, or solvents that could stain or damage floor coverings. With easy score-and-snap installation, it's a versatile choice for any interior flooring or countertop application.

FAQS

What is the difference between hardwood and engineered wood flooring?

Hardwood is made from solid wood planks, while engineered wood has a real wood surface over layered plywood, making it more stable and moisture-resistant.

Is porcelain or ceramic tile better for my home?

Both are durable, but porcelain is denser, more water-resistant, and ideal for high-moisture areas, while ceramic offers a wide range of designs at a lower cost.

Can laminate or LVT be installed over existing floors?

Yes, both can often be installed over most existing floors, provided the surface is clean, dry, and level.

Which flooring options are waterproof?

Porcelain tile, ceramic tile, and most LVT products are waterproof, making them perfect for kitchens, bathrooms, and basements.

How do I maintain my flooring for long-lasting beauty?

Sweep or vacuum regularly, clean spills promptly, and use manufacturer-recommended cleaners to avoid damage.

Which flooring option is best for high-traffic areas?

For spaces like hallways, kitchens, and commercial areas, durable choices include porcelain tile, LVT, and high-AC-rated laminate.
