STYROFOAM™ BRAND ULTRA SL WALL SYSTEM
Styrofoam™ Brand Ultra SL Extruded Polystyrene Foam 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.
With its closed-cell structure offering advanced long-term thermal performance and moisture control, Styrofoam™ Brand Ultra SL Insulation with shiplap edges maximizes the performance of the entire wall assembly.
