1. Limited to single layer application.

2. The surface burning characteristics of these products have been determined in accordance with ASTM E84. This standard should be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating.

3. Preproduction qualification testing complete and on file. Chemical analysis of each production lot required for total conformance.

4. Sample modified as required to meet applicable test method.

5. XPS foam core values meet ASTM C578 TYPE IV.

6. k means the apparent thermal conductivity. The lower the value, the greater the insulation power.

7. Values at yield or 10% deflection, whichever occurs first.

8. Data ranges from 0.00 to value shown due to the level of precision of the test method.

9. Water vapor permeance decreases as thickness increases.

10. These laboratory tests are not intended to describe the hazard presented by this material under actual fire conditions.

11. Fire performance of 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 Fabrication Billets have not been tested.
