13 Samples modified as required to meet applicable test methods. 1. XPS foam core value 2. k = Btu in./hr ft 2 F; = W/m C. T he lower the value, the greater the insulation power. 3. Values at yield or 10% deflection, whichever occurs first. 4. Water vapor permeance decreases as thickness increases. 5. Burning characteristics laboratory tests are not intended to describe the hazard presented by this material under actual fire conditions. 6. Test results are for FOAMULAR 4" thick product only. Thicker products may have different fire performance characteristics. Due to limits on the equipment used to test per ASTM E84, Owens Corning FOAMULAR XPS Pipe Insulation have not been tested. 7. Fire performance of products fabricated using FOAMULAR XPS Pipe Insulation may vary in the field depending on facings and adhesives used in the fabrication process. Fabricators should be consulted if composite fire performance is required.
