(1.1mm)","description":"\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.375rem] font-bold\"\u003eFloorMuffler Encore Underlayment for Vinyl Plank \u0026amp; Rigid Core Flooring\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eMost underlayments aren't made for today's vinyl floors. FloorMuffler Encore is. This premium 1.1mm XLPP underlayment is purpose-built for luxury vinyl plank and rigid core flooring (SPC and WPC) — including planks that already have a pre-attached pad. Where standard foam is too thick and too soft for vinyl click systems, Encore's low-profile, high-density construction supports the locking mechanism instead of stressing it.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eYes — It Works With Pre-Attached Pad\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eHave rigid core flooring with the pad already attached? Encore is one of the few underlayments engineered to go underneath it, adding sound reduction and moisture protection without compromising the locking system or your flooring warranty. That makes it the answer to one of the most common questions in vinyl flooring — \"can I add underlayment under attached-pad LVP?\" With Encore: yes.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eBuilt-In Moisture Barrier\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe closed-cell XLPP core is itself a moisture barrier — no separate vapor film required. Over concrete slabs and in basements, that's the layer standing between subfloor moisture and your floor.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eQuieter Vinyl Floors\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eRigid core floors can sound hollow and clicky underfoot. Encore delivers up to 69 dB IIC, 62 dB STC, and a 22 dB Delta IIC, cutting impact noise and that hollow sound — and helping vinyl installs clear condo and HOA sound requirements.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eProtects the Click, Smooths the Sub\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 1.1mm, Encore stays within the thin, firm profile vinyl manufacturers call for, with outstanding compression strength that keeps tongue-and-groove joints tight under traffic. It smooths minor subfloor imperfections, adds an R-4.0\/inch thermal layer, and is compatible with electric and hydronic radiant heat.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhere it works best:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLuxury vinyl plank (LVP) and luxury vinyl tile (LVT) floating floors\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSPC and WPC rigid core flooring — with or without attached pad\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCondos, apartments, and rentals where sound matters\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eConcrete slabs, basements, and plywood subfloors\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRadiant heat installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eBacked by FloorMuffler's limited lifetime residential warranty and 10-year commercial warranty.\u003c\/p\u003e","brand":"BuildDirect","offers":[{"title":"Premium Underlayment","offer_id":45481160343849,"sku":"15270229","price":79.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4289\/9753\/files\/15270229-00-pdp.png?v=1689634039","url":"https:\/\/www.builddirect.com\/fr\/products\/encore-underlayment","provider":"BuildDirect","version":"1.0","type":"link"}
