and smoke development ≤ 450 meet code requirements for foam plastic roof insulation. Codes exempt foam plastic
insulation when used in FM 4450 or UL 1256. Physical properties listed above are presented as typical average
values as determined by accepted ASTM test methods and are subject to normal manufacturing variation.

LTTR (long term thermal resistance) values were determined in accordance with CAN/ULC-S770-09. Test samples
were third-party selected and tested by an accredited material testing laboratory. The LTTR results were reviewed by
FM Global and certified by the PIMA Quality Mark Program.
2 RSI is the metric expression of R-value (m 2 • K/W).
*Multi-layer application is strongly recommended when the total insulation thickness exceeds 2.7"
ACFoAm ® -IV InsulAtIon
DescriPtion:
aDVantages:
aPPlication:
installation:
Closed-cell polyisocyanurate (polyiso) foam core integrally bonded to heavy weight high performance inorganic coated glass facers. ACFoam ® -IV is
offered in a variety of thicknesses, providing long-term thermal resistance (LTTR) values from 5.6 to 23.6. Available in 4ft x 4ft (1220mm x 1220mm)
and 4ft x 8ft (1220mm x 2440mm) panels. Manufactured in accordance with
ASTM C1289, Type II, Class 2, Grade 2 (20 psi) or Grade 3 (25 psi) and
CAN/ULC-S704 Type 2, Class 3 or Type 3, Class 3.
When using ACFoam ® -IV in adhered systems, field testing has confirmed significantly more efficient use of solvent-based adhesives than with organic
faced insulations. Adhesive application rates vary by manufacturer. Check adhesive manufacturer’s recommendation for application rates. The number
of fasteners required to attach ACFoam
® -IV in a mechanically attached membrane roof system has been reduced from 5 to 4. Manufactured using
CFC-, HCFC- and HFC-free foam blowing technology with zero ozone depletion potential (ODP) and virtually no (negligible) global warming potential
(GWP). Recognized by the GREENGUARD Environmental Institute as resistant or highly resistant to mold growth based on independent testing using
GREENGUARD Test Method GGTM.P040 (ASTM D6329) for microbial resistance. ACFoam
® -IV contains between 4.2% and 9.0% recycled materials
by weight. Class A ratings can be achieved with ACFoam®-IV in a minimum thickness of 1.0" when placed directly on a combustible deck (1:12
maximum deck slope).
Manufactured and tested for use in new and re-roofing applications. ACFoam ® -IV is used in built-up (BUR), modified bitumen, metal, ballasted single-
ply, mechanically attached single-ply and adhered single-ply roofing systems. These roofing systems depend on proper installation for successful
performance. Refer to FM Approvals
® RoofNav and UL Online Certifications Directory for additional application details.
ACFoam ® -IV shall be kept dry before, during and after installation. This product will burn if exposed to an ignition source of sufficient heat and intensity.
Do not apply flame directly to ACFoam ® -IV insulation. Refer to PIMA Technical Bulletin 109: Storage and Handling Recommendations for Polyiso Roof
Insulation. An offset or staggered multi-layer application of ACFoam ® is strongly recommended when the total insulation thickness exceeds
2.7" (Atlas Technical Bulletin: TB-5). Typical field fastening requirements can be obtained from membrane system manufacturer or FM Global
Property Loss Prevention Data Sheets 1-29.
Prior to installation, Atlas Roofing Corporation recommends that you consult your local building codes, contract documents, professional engineer, FM
Global, Miami-Dade County and membrane manufacturer for additional installation guidelines as well as design enhancements.
