Why do i need to leave a 10mm expansion gap around the perimeter?
Because laminate flooring is derived from wood, it is subject to expansion caused by room temperatures and humidity levels. An expansion gap is a necessary part of any successful installation because it allows space for the expansion of the floor as it responds to these external influences of temperature and humidity. When it is exposed to warmer temperatures, or to increased humidity, laminate flooring planks expand outward. Leaving out the essential element of an outside gap can cause the buckling of the individual laminate flooring planks as the planks push outward against walls or other obstacles.
