2 XPS foam core values meet ASTM C578 TYPE IV.
3 k means the apparent thermal conductivity. The loWer the value, the greater the insulation poWer.
4 Values at yield or 10% deflection, Whichever occurs first.
5 Data ranges from 0.00 to value shoWn due to the level of precision of the test method.
6 Water vapor permeance decreases as thickness increases.
7 These laboratory tests are not intended to describe the hazard presented by this material under actual fire conditions.
8 Fire performance of FOAMULAR® 4-inch-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® NGX Fabrication Billets have not been tested.
