Review on 12 Inch X 1/2 Inch X 59 Inch Neoprene Foam Insulation Sheets With Adhesive - Multi-Function Soundproof Large Marine Closed Cell Rubber Roll (Black) by Frank Garahana

My husband needed some closed cell foam to act as a waterproof barrier between the pressure treated lumber base of our new shed and the concrete pads that the shed sits upon. This worked great for the purpose! The fact that it has an adhesive side made installation easier. He jacked up the shed, applied the adhesive side of the foam to the underside of the shed just where it would sit on the concrete pads, then lowered the shed back down. Use a razor blade to make precise cuts to your exact dimensions.
