FOAMULAR® NGX® 400/600/1000 | Owens Corning Insulation

WHY CHOOSE FOAM BOARD INSULATION?

Owens Corning® FOAMULAR® NGX® 400/600/1000 is high-strength Extruded Polystyrene (XPS) insulation designed for use in engineered applications requiring additional load-bearing capability, such as under slab, concrete floors, foundations, roadways and rail beds, plaza and parking decks, and cold storage installations. FOAMULAR® NGX® 400/600/1000 can also be used in tapered insulation systems when higher compressive strength is needed.

Technical Information

  • Deliver FOAMULAR® NGX® XPS insulation products in their original factory-wrapped packaging.
  • Exposure to exterior conditions during normal construction cycles is permitted. During that time some fading of color may begin due to UV exposure, and, if exposed for extended periods of time, some degradation or “dusting” of the polystyrene surface may begin. It is best if the product is covered within 60 days to minimize degradation. Once covered, the deterioration stops, and damage is limited to the thin top surface layers of cells. Cells below are generally unharmed.
  • Prior to use of adhesives, sealants or other similar products with polystyrene boards, verify their compatibility with adhesive manufacturers.
  • In soils that may contain hydrocarbons and other petroleum derivatives, and all other products that may cause corrosion and deterioration of the polystyrene boards. Consult soils investigation reports and an Owens Corning Area Sales Manager.
  • Caution: This product is combustible. A protective barrier or thermal barrier is required as specified in the appropriate building Code. Do not expose to open flames or any other ignition source during transport, handling, storage or use. A protective barrier or thermal barrier is required to separate this product from interior living or conditioned spaces as specified in the appropriate building code.
  • Ensure surfaces to be covered with insulation boards have been inspected, notably; substrate solidity and level - fill and others; and subsurface mechanical, electrical and telecommunication service lines penetrating or in proximity to insulation boards.
  • Carefully adjust insulation boards to obtain tight joints between each board; where two layers are required, overlap all joints. Backfill insulation boards or use wood or steel pegs to avoid their displacement due to wind or flotation on water puddles generated by the rain or during subsurface work or near watercourses. Where required, adhere insulation boards together temporarily using an adhesive.
