Styrofoam Rigid XPS, White, Untrimmed

Polystyrene Rigid Foam boards are high-density, pure white cellular block materials engineered specifically to provide effortless hot-wire cutability, clean light reflection, and brilliant dimensional stability for architectural scale models, urban master planning, and sculptural prototyping. Featuring a fine, uniform cell structure and a neutral white tone, this specialised rigid foam provides architects, urban planners, and design students with a great physical substrate for constructing rapid massing models, topographic contour maps, and conceptual volumetric studies without needing any surface painting or secondary finishing.

Unlike standard construction-grade insulation foams that are dyed pink, blue, or yellow, this foam is specifically made in a bright white finish calibrated for professional model making. The high-density cellular matrix melts cleanly under the heat of a hot wire cutter, leaving razor-sharp edges and smooth, clean surfaces free from drag lines or fraying. It can easily be shaped using serrated blades, rasps, or sandpaper, and stuck down securely using solvent-free adhesives such as PVA, polyurethane foam glue, or specialised foam-safe sprays. On top of that, the material is strictly HBCD-free, ensuring safe, non-toxic handling during studio fabrication and trimming work.

Available in a broad selection of sheet thicknesses, untrimmed board formats, and volume choices across the product range, these white polystyrene rigid foam sheets deliver a versatile, professional-grade solution for outfitting architectural design studios, university workshops, and high-fidelity presentation displays.
