Owens Corning has launched FOAMULAR NGX, a next generation extruded polystyrene rigid foam insulation that cuts embodied carbon by 70 percent compared to its legacy FOAMULAR line. The product uses a different blowing agent blend to reduce global warming potential while keeping the same compressive strength, R-values, and pink board appearance that contractors already know. NGX is available at Home Depot and through commercial supply channels across the US and Canada. FOAMULAR NGX targets builders and architects who need continuous insulation for walls, foundations, and roofs under modern energy codes. The boards come in thicknesses from 0.5 to 4 inches with compressive strengths up to 40 psi, making them suitable for below-slab and below-grade use. Owens Corning says the product cuts embodied carbon by 70 percent compared to its legacy FOAMULAR line, which matters as regulators and developers push for lower upfront emissions in construction. For contractors, the switch is straightforward. NGX cuts and installs the same way as older XPS boards, so no new tools or training are needed. The main difference is the environmental label and a slightly different blowing agent. Pricing is similar to traditional FOAMULAR, and the product is already on shelves at Home Depot and other major retailers. This is a practical step for builders who want to reduce embodied carbon without changing their workflow.
