Hartco Oak Parquet vs 3mm Floor Underlayment: Which Flooring Tile Stone Purchase Fits Your Project?

Real oak parquet tiles or a 400 sq ft underlayment roll? Compare the Hartco Oak Parquet and the 3mm Floor Underlayment to see which flooring tile stone purchase fits your project.

Last updated Aug 17, 2026

When you're planning a flooring tile stone project, the first question isn't always color or texture. It's whether you need a finished walking surface or a foundation layer underneath. The two products here sit on opposite sides of that line: a box of Hartco oak parquet tiles and a large roll of underlayment built for the prep layer. Both are new, but they're meant for different moments in the same project.

Quick verdict

Go with the Hartco Oak Parquet if you need real hardwood in a small area. Go with the underlayment if you're prepping a large footprint for a floating floor. The listed prices are different enough to matter: USD 89.95 for the parquet box and USD 191.82 for the underlayment package.

Where each product wins

Hartco Oak Parquet wins when you want a visible wood surface. The six-inch squares are real solid oak with a natural urethane finish, tongue-and-groove edges, and a glue-down installation. It's the product you see, walk on, and match to existing wood.

Floor Underlayment wins when you need a large prep layer. The recycled fiber plus PE film construction and attached vapor barrier give the floor structure below the surface, with soundproofing built in. It's the product that does its job invisibly.

Product notes

Hartco Oak Parquet

OAK PARQUET FLOOR: 20pcs 6"x6"x5/16": Hartco Natural 5 Sq ft NEW

This box holds real HARTCO solid oak in a natural tone, already finished with urethane. Each 6x6-inch tile is 5/16 inch thick, and the tongue-and-groove edge allows a glue-down fit. The easy-install angle is genuine: individual squares go down one at a time, which makes this a practical choice for matching a damaged spot or creating a parquet accent. The box delivers five square feet total, so keep expectations tight on square footage. This is a surface you walk on, not a cushion or barrier. If your project is bigger than a patch, you'd need several boxes or a different plan.

Floor Underlayment Roll

Floor Underlayment 400 Sq. Ft, 3Mm Laminate Flooring Padding with Attached Vapor

This underlayment is built for the layer beneath your floor. It comes as two rolls that combine for 400 sq ft, with a 3mm thickness (about 0.12 inches) and a strong recycled fiber plus PE film construction. The attached vapor barrier helps keep moisture away from laminate, vinyl, or wood floors, and the soundproofing is designed to cut noise between levels. If your job is a large floating floor, this is the prep layer that makes the finished surface feel steadier. The limitation is that it is not a visible floor covering. It sits below the surface, so it won't give you any kind of decorative finish. You still need a separate laminate, vinyl, or wood layer on top.

Final choice by use case

Pick the Hartco Oak Parquet when you want actual wood to repair a small area, build a parquet accent, or test a match against your existing floor. Choose the Floor Underlayment when you're covering a big space with a floating floor and need moisture protection in one underlayment. These two buy different steps of the job; this comparison helps you see which step you're on.
