Floating floors require an expansion gap around the entire perimeter, including fixed cabinetry and door frames. This gap accounts for natural expansion caused by temperature fluctuations. To calculate, measure the thickness of the manufacturer-recommended spacer (typically 1/4 to 3/8 inch) and place them consistently along every wall. Never wedge the planks tightly against a wall, as this restricts movement and will lead to tenting, buckling, or localized joint failure during high-temperature cycles.

How is the perimeter gap calculated for floating floors?
Perimeter gaps are calculated based on the manufacturer's specified expansion requirement, usually 1/4 inch to 3/8 inch. Use spacers against all vertical surfaces to maintain this gap, which allows the floor to expand and contract without buckling.
