Springstep IV doesn’t require installation products. Its patented tongue and groove system allows even the most novice installer to easily snap its components together. It requires no nails, glue, or screws. You will need a circular saw to custom fit the panels to your room, but the floor panels require relatively little cutting. The Springstep IV does not attach to floors or walls, yet has the appearance and functionality of a permanent subfloor. The Springstep IV subfloor easily transfers to the next location, and it is always possible to add or subtract more square footage.
