DuPont™ Styrofoam™ Brand Square Edge ST-100 Insulation* is an extruded polystyrene foam (XPS) insulation board that meets the needs of the commercial foundation and building floor slab market and can also be used for foundations/slabs in residential applications. U.S. HFC Regulation Compliant Formulation

Uses:

  • Agricultural building applications

  • Residential above and below grade applications

  • Commercial above and below grade applications

  • New construction

  • Reconstruction and retrofitting

  • Transportation

  • Refrigeration

  • Walk-in coolers and refrigerated warehouses

  • Garages and panels

Advantages:

• are easy to handle, cut using a utility knife or serrated blade and install
• provide a weather resistant barrier to enhance the building’s resistance to air and moisture penetration
• can be used in a number of applications like sheathing, foundation walls, masonry cavity walls, and more
• come in a wide selection of sizes and thicknesses
• have a minimum compressive strength of 25 psi and a flexural strength of 50 psi
• are designed to help ensure energy efficiency and minimize on-site cutting and waste
• are resistant to degradation from soil components and will retain insulating performance characteristics after prolonged exposure to moisture
• provide a secondary barrier against groundwater leakage
• help protect foundation dampproofing and waterproofing, especially during backfilling
• minimize the freeze-thaw cycling of the foundation, reducing the potential for cracking
• warm the foundation, reducing the potential for condensation
• will not corrode, rot or support mold growth

FREEZERMATE™ XPS Insulation

FREEZERMATE™ Extruded Polystyrene (XPS) foam insulation a STYROFOAM™ Brand solution for use as subfloor thermal insulation in low-temperature applications. It features smooth, high density skins with excellent insulating characteristics, high resistance to water and water vapor, excellent freeze-thaw resistance, superior compressive strength and long-term durability. FREEZERMATE™ Insulation can also be used in most static and dynamic loading situations for flooring applications. Because the rigid foam insulation boards resist even severe forms of moisture penetration in freezer and cooler construction, they offer long-term R-values* superior to other types of thermal insulation.

Uses:

  • Specially designed for use in low-temperature applications as subfloor thermal insulation

  • Used for most static and dynamic loading floor applications

Advantages:

  • Resists even severe forms of moisture penetration in freezer and cooler construction

  • Offers long-term R-values superior to other types of thermal insulation

  • Smooth, high-density skins

  • Excellent freeze-thaw resistance

  • Excellent compressive strength (min. 30 psi)

  • Long-term durability

  • Contains an average of 20% pre-consumer recycled content certified by UL Environment Inc.

HighLoad XPS Insulation (40,60,100)

HIGHLOAD™ Extruded Polystyrene (XPS) Foam Insulation is a STYROFOAM™ Brand solution designed for use in low-temperature (freezer floor) applications, highways, airport runways, bridge abutments, parking decks, utility lines, ice rinks and plaza decks. Available in compressive strengths of 40, 60 and 100 psi (275, 415 and 690 kPa), HIGHLOAD insulation features exceptional moisture resistance and R-value retention. All three HIGHLOAD insulation products resist compressive creep and fatigue, delivering long-term compressive strength. Like all STYROFOAM™ insulation products, HIGHLOAD 40, 60 and 100 are durable, versatile and reusable – making them a preferred choice for a variety of high-load applications. It is the responsibility of the designer to select the proper STYROFOAM™ HIGHLOAD insulation product based on the dead and live loads expected in the application
