Floating flooring relies on a 'floating' installation, meaning it is not secured to the subfloor and must move to accommodate thermal expansion. Heavy appliances exert significant downward pressure (pinning force) that restricts this movement. If the floor cannot expand, it may buckle or experience seam damage at the joints. Some manufacturers recommend installing appliances on the subfloor and running the flooring up to the appliance feet, or using specialty floor protection pads to distribute the weight. Always consult the product's installation manual, as some warranties may be voided if floating floors are installed under excessive, permanent, point-loaded weights without proper accommodation.

What is the impact of heavy kitchen appliance weight on floating flooring?
Floating floors are designed to expand and contract as a single unit. Placing heavy kitchen appliances, such as commercial-grade refrigerators or ranges, directly on floating floors can pin the material in place, preventing natural movement. This often results in buckling or joint separation. If the manufacturer permits, consider using weight distribution shims or installing a perimeter gap that accounts for heavy loads. Check your product manual for weight limitations.
