Is Pergo flooring really waterproof?

Is Pergo flooring really waterproof? Some Pergo flooring is really waterproof, specifically Pergo Outlast, Pergo Extreme, and Pergo WetProtect lines which are marketed as waterproof with up to 24 to 72 hours water protection, while standard Pergo laminate is water-resistant not fully waterproof. Pergo invented laminate in 1977, with standard laminate water-resistant handling spills if wiped quickly but not standing water, with HDF core swelling if water seeps. Pergo Outlast with WetProtect technology has sealed joints and water-resistant core making it waterproof for up to 24 hours, suitable for kitchens, bathrooms, and basements, with warranty for wet areas. Pergo Extreme is rigid vinyl LVP which is 100 percent waterproof as vinyl, not laminate. So is Pergo flooring really waterproof? Yes, Pergo Outlast and Pergo Extreme are really waterproof, tested for standing water, with tight click lock preventing seepage, while standard Pergo laminate is water-resistant, so check product label for waterproof, with waterproof Pergo costing 2.50 to 4 dollars per square foot, offering wood look with waterproof protection, making it good for wet areas, but not all Pergo is waterproof, only specific lines labeled waterproof, so read specs before buying for bathroom.
