DuPont Styrofoam™ Ultra SL Extruded Polystyrene Foam Insulation
Categories: Polymer; Thermoplastic; Polystyrene (PS); Expanded Polystyrene (EPS)
Material Notes: STYROFOAM™ Brand Ultra SL Insulation is a moisture-resistant, durable and lightweight extruded polystyrene foam board with shiplap edges designed specifically to be used as a continuous insulation (ci) and installed over block, concrete or metal stud backup behind masonry or stone veneers. Manufactured with a patented carbon-black technology, STYROFOAM™ Brand Ultra SL Insulation features an R-value of 5.6 per inch (RSI of 0.97 per 25 mm), the highest of all extruded polystyrene foam insulation products. Its closed-cell structure offers advanced long-term thermal performance and moisture control. STYROFOAM™ Brand Ultra SL Insulation with shiplap edges maximizes the thermal performance of the wall assembly.

This material is produced as sheets of closed-cell foam by a continuous extrusion process. Its properties will be different than expanded polystyrene beads because beads have voids between cell walls.

This former Dow product line is now a DuPont product line.
