- Typical property values are based principally on most recent
product audit and sampling data. For specific property ranges
and bounds, contact you DiversiFoam Products representative.
- Because of ongoing technical discussions regarding the complete
application of test methods C117-76 and C518-76, traditional
industry methods for determining the thermal conductivity of low
density insulations are used. test uncertainty of thicker foam
insulations is expected to be less than 5 percent from listed
values.
- Recommended typical design values after five-year aging at 75°F.
- Partially aged values after six-month
aging at 75°F or three-month
aging at 140°F. These values are not recommended for use in
design calculations. They are included for comparison with
published values for polyisocyanurate and polyurethane foams
measured after aging for these periods according to RIC/TIMA
procedure 281-1.
- Fresh or "as manufactured"
k factors for comparison purposes only. DiversiFoam Products
and XEPS industry organizations continue to recommend that long-term
aged values be used for design calculations.
- Test precision is plus or minus 1.0
percent by volume.
- Values will be between 0.0 and the
values shown.
- Desiccant method. For all
CertiFoam products one inch or greater in thickness.
- Vertical compressive strength at 10%
deformation or yield, whichever occurs first. Structural
applications involving high continuous loads, high temperatures, or
non-uniform loads may require higher safety factors based on minimum
specification values.
- Vertical compressive strength at 5%
deformation or yield, whichever occurs first. To minimize
viscoelastic deformation with time in load-bearing applications,
higher safety factors are recommended: 3:1 for dead loads, and
5:1 for live or combined loads. Elevated temperatures may also
require higher safety factors.
