(2mm)","description":"\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.375rem] font-bold\"\u003eFloorMuffler ComboFoam 2-in-1 Underlayment with Attached Vapor Barrier\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eTwo jobs, one roll, one low price. FloorMuffler ComboFoam combines a 2mm cushioning foam with an attached vapor barrier film, so you get underlayment and moisture protection in a single pass — no separate poly sheeting, no extra step. It's the budget-smart foundation for floating laminate, engineered hardwood, and solid hardwood floors.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eVapor Barrier Built In\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe attached film layer blocks moisture migrating up from the subfloor — the protection laminate and wood floors need over concrete slabs and in vapor-prone areas. Roll it out, tape the seams, and the moisture layer is done.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eReal Sound Numbers at a Value Price\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eComboFoam carries a 61 dB IIC and 54 dB STC rating — genuine, tested acoustic performance that takes the hollow clack out of floating floors. For bedrooms, living areas, rentals, and flips, that's the comfort upgrade tenants and buyers notice, at a price that works across a whole property.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eMade for Volume Work\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 100 square feet per roll and 46.5 inches wide, ComboFoam covers rooms fast with fewer seams. It's lightweight, lies flat, cuts with a utility knife, and won't slow down a crew turning multiple units. For landlords, flippers, and production work, it's the spec that keeps material cost per door predictable.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eFrom the FloorMuffler Family\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eComboFoam is made by FloorMuffler, the underlayment brand pros know — backed by a 10-year residential warranty.\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\"\u003eFloating laminate, engineered, and solid hardwood floors\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eConcrete and plywood subfloors\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRental turnovers, flips, and budget remodels\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBedrooms, living rooms, and whole-home installs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eGood to know:\u003c\/strong\u003e Not for use with radiant heat systems or flooring with a pre-attached pad.
