Applicable Standards
Factory Mutual
Fesco Foam has a Factory Mutual (FM) Class 1 fire rating and
90 to 180 wind-resistance ratings with numerous BUR and
modified bitumen constructions. This testing is specific to the
roof deck, insulation, fastener, fastener pattern and the
membrane. For current information on JM Factory Mutual
approved systems, contact a JM Technical Service Specialist,
Sales Representative or consult the current FM Approval
Guide.
Underwriters Laboratories
Fesco Foam is classified by Underwriters Laboratories, Inc.
(UL) and Underwriters Laboratories Canada as an approved
insulation for numerous Class A roof constructions. Contact JM
for more details regarding specific approvals.
Fesco Foam is listed by UL for use in Construction Numbers 1,
2, 157 and 158. See the current UL Roofing Materials and
Systems Directory.
UL Fire-Rated Assemblies
Fesco Foam is listed by Underwriters Laboratories, Inc. for use
in fire-rated assembly design numbers P225, P230, P259,
P508, P510, P514, P701, P710, P713, P717, P718, P719,
P720, P722, P723, P724, P727, P728, P729, P730, P734,
P735, P739, P801, P814, P815, P818, P819 and P828. See
current UL Fire Resistance Directory.
Other Approvals
Fesco Foam complies with the requirements of ASTM C 1289
and CCMC 12786-R.
Fesco Foam has been approved by numerous municipalities
including Dade County, FL and California State Insulation
Quality Standards and Title 25 Foam Flammability Criteria.
Fesco Foam also meets the requirements of BOCA, ICBO,
SBCCI and others.
Because this insulation complies with both FM 4450 and 4470
when tested in roof membrane assemblies, and is listed as a
FM Class 1 roof insulation, there is no requirement for the "½"
(13 mm) gypsum wallboard or equivalent thermal barrier," when
applied in steel deck roofing applications to meet code
requirements (e.g., SBCCI, BOCA, ICBO, etc.). The local code
official does have final discretion for approval of roof
assemblies. Fire-rated roof/ceiling assemblies ("P" designs)
may require the use of a thermal barrier.
Federal Specifications
Fesco Foam meets the physical property requirements
specified in Federal Specification HH-I-1972/Gen and
HH-I-1972/3.
JM insulation products must be protected from open flame and
kept dry at all times. Install only as much insulation as can be
covered the same day by completed roof covering material.
JM will not be responsible for specific building and roof
design by others, for deficiencies in construction or
workmanship, for dangerous conditions on the job site or
for improper storage and handling.Technical specifications
as shown in this literature are intended to be used as general
guidelines only. Consult JM for detailed specifications.
