FOAMULAR® NGX™ 150 0.5 in. x 4 ft. x 8 ft. R-3 Squared Edge XPS Rigid Foam Board Insulation

Product Description

FOAMULAR® NGX™ 150 0.5 in. x 4 ft. x 8 ft. R-3 Squared Edge XPS Rigid Foam Board Insulation (Half-Inch) is a durable, moisture-resistant rigid foam insulation board designed for residential, commercial, agricultural, and light industrial building applications. Manufactured by Owens Corning, this 0.5-inch extruded polystyrene insulation board delivers R-3 thermal performance in a standard 4 ft. x 8 ft. sheet, making it a practical choice for projects that require thin-profile continuous insulation, improved energy efficiency, and reliable long-term performance, especially where space is limited. FOAMULAR® 150 XPS insulation is commonly used for wall furring, foundation insulation, crawlspace insulation, cavity walls, precast concrete, under-slab applications, roofing systems, and exterior sheathing. Its closed-cell XPS structure helps resist moisture absorption while maintaining dependable insulating value in demanding environments where condensation, ground moisture, water exposure, or freeze/thaw cycling may be a concern. With its 15 PSI compressive strength, FOAMULAR® 150 is well suited for many general-purpose rigid foam insulation applications where a balance of strength, insulation value, and cost efficiency is needed. As the thinnest XPS board available, the 0.5-inch thickness is ideal for applications requiring a low-profile continuous insulation layer or for minimizing thermal breaks in existing structures. The squared-edge board design allows for straightforward installation across large surface areas, helping contractors, builders, and property owners create a continuous insulation layer with fewer thermal breaks. Whether you are insulating a basement wall, improving building envelope performance, adding rigid foam beneath siding, or sourcing bulk XPS foam board for a construction project, FOAMULAR® NGX™ 150 provides a dependable solution backed by the Owens Corning name.

XPS rigid foam board is valued for its combination of thermal resistance, moisture resistance, dimensional stability, and jobsite durability. Unlike some insulation types that can lose effectiveness when exposed to moisture, FOAMULAR® XPS insulation is designed to retain its long-term R-value even in environments where water exposure, condensation, or freeze/thaw conditions may occur. For builders and contractors, rigid foam insulation can also help reduce thermal bridging when installed as a continuous insulation layer. This can improve overall wall, roof, or foundation performance and support more energy-efficient construction.
