Specifically designed for floating floor installations, this foam Expansion Gap Filler is the ideal solution for filling perimeter expansion gaps in laminate, engineered wood, and other floating floor systems. By creating a compressible, non-adhesive filler between the floor edge and adjacent walls or vertical surfaces, this expansion gap filler ensures proper expansion and contraction space is maintained, helping to prevent buckling or warping over time. The closed-cell foam construction resists moisture and provides a consistent base for perimeter sealants where required. Easy to install, it's a must-have for any professional or DIY installer seeking a clean, long-lasting finish in floating floor applications.
