Manufacturer instructions beat any web page, including this one.
On slabs, vapor rules and underlay thickness are where warranties live or die. On wood subfloors upstairs, the brand may want a different stack entirely.
Underyoo does not merchandise adhesives. If the install needs thinset or branded adhesive, that stays outside our catalog.

Buyer questions
Cork underlayment is a natural cork layer under floating hard-surface floors (and some tile-prep stacks when specified). It adds resilience, sound absorption, and a warmer feel versus bare subfloor. Thickness is often around 3–6 mm (about 1/8–1/4 in) — always confirm your flooring brand’s max underlay thickness.
Cork itself is vapor-open compared with closed-cell foam with integrated film. On slabs and grade, many flooring brands still require a separate poly vapor retarder under or with the cork. Read the plank install sheet: do not assume cork alone replaces a required moisture film.
Yes when thickness and density are within the brand’s rules. Cork can feel slightly more cushioned than ultra-firm IXPE; some rigid-core LVP lines prefer thinner, firmer foam. Confirm mm limits, especially if planks already have attached pad.
Choose cork when you want a natural material story, sound absorption, and a resilient walk, and your brand allows the thickness. Choose foam (IXPE/EPE/fiber) when you need a thin firm pad, integrated vapor film, or the plank warranty specifies a foam product. Job and warranty beat preference alone.
CAPITOL premium cork underlay 6 mm 200 sq ft is natural cork floor underlayment for floating hard-surface floors (LVP, laminate, engineered wood) when the brand allows cork thickness. It sits under the planks for sound and resilience. It is not wall-to-wall carpet cushion and not a mattress topper.
No. Carpet padding (rebond, rubber, felt cushion) is designed for stretch-in or glue-down wall-to-wall carpet. Floor underlayment is a thin, compression-resistant layer for floating hard floors. Using carpet pad under LVP or laminate can void warranties and feel soft or uneven under rigid core.
Often yes — but only when this product’s thickness and moisture features match your LVP brand’s install sheet. Many rigid-core planks cap underlay thickness (sometimes 1–1.5 mm, sometimes up to ~2–3 mm) or ban extra pad if foam is already attached. Confirm max mm, vapor rules for slabs, and whether pre-attached pad forbids a second layer before you cut rolls.
Most floating laminate systems want an approved underlay for sound, minor leveling feel, and moisture control on slabs. Some laminate ships with pre-attached underlay — in that case extra pad may be restricted. Read the laminate brand’s stack diagram; Underyoo notes help you shop the underlay category, not override the warranty.
No. Mattress toppers are sleep layers for beds. Floor underlayment is a thin construction layer under floating floors. Sleep foam is too soft, too thick, and the wrong chemistry for plank warranties.
No. Prices and stock on Underyoo are approximate hints to help you compare. Amazon’s listing is the source of truth for live price, shipping, tax, and availability at checkout.
No. Underyoo merchandises what goes under floors, rugs, furniture, and sleep systems — underlayments, pads, membranes, support foam, and mattress toppers. We do not list glue pails, peel-and-stick adhesive underlay SKUs, or tape as primary products. If your install needs thinset or a brand-specified adhesive, that stays on the flooring manufacturer’s system.
Checkout, payment, shipping, and returns are handled on Amazon through the product or search link. Underyoo is a discovery and notes hub, not the retailer of record.
