Extruded Polystyrene (XPS) R15 Rigid Foam Board is a high-performance insulation solution designed for projects that demand strong thermal resistance, moisture protection, and long-term durability. Measuring 24" x 48" x 3", these rigid foam boards deliver an impressive R-value of 15 while maintaining a high compressive strength of 300 kPa, making them ideal for foundations, basement walls, under-slab insulation, exterior continuous insulation, and other demanding applications. Unlike soft batt insulation that sags or compresses over time, XPS foam boards provide a dense, durable layer of insulation that helps reduce thermal bridging and improve overall energy efficiency. Their lightweight design makes handling and installation straightforward, because apparently construction wasn’t already enough of a full-body punishment. Available in bundles of 10 boards, these panels are easy to cut, fit, and install for both contractors and DIY builders looking for reliable insulation performance at an affordable price.
