This 42-inch by 125-foot roll of Blue Wave wall foam provides a lightweight, moisture-resistant barrier designed specifically for in-ground pool walls up to 48 inches high. Unlike open-cell foams that absorb water and deteriorate, the closed-cell polyethylene used here resists moisture, keeps its shape season after season, and adds a modest thermal benefit to help reduce heat loss through pool walls.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this wall foam protect my vinyl liner?\u003c\/h3\u003e\n\u003cp\u003eThe foam creates a continuous smooth layer between the hard pool wall and the vinyl liner, reducing friction points and surface irregularities that cause tears.
