Vinyl flooring is relatively stable compared to natural wood, but it still undergoes dimensional changes due to thermal expansion. If the temperature in a room rises significantly, the planks can expand. Without adequate perimeter gaps, this expansion causes the floor to push against walls, leading to buckling or joint failure. The exact rate of expansion is usually defined in the manufacturer's technical data sheets. Proper spacing around all vertical obstructions is required to ensure the flooring remains flat and level throughout the year.

What is the expansion rate of vinyl planks?
Vinyl planks typically expand and contract based on ambient temperature fluctuations rather than moisture. While specific rates vary by product, a standard industry recommendation is to maintain an expansion gap of at least 1/4 inch around all perimeter walls and fixed objects.
