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.

Tapered aCFoam ® -III InsulaTIon
DescriPtion:
aDvantages:
aPPlication:
installation:
Closed-cell polyisocyanurate (polyiso) foam core integrally bonded to inorganic coated glass facers. Tapered ACFoam ® -III is offered in a variety of
slopes, to achieve positive drainage as well as long-term thermal resistance (LTTR). Available in 4ft x 4ft (1220mm x 1220mm) panels with 1/8" (3mm),
1/4" (6mm) and 1/2" (12mm) per foot slope. 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 Tapered ACFoam ® -III 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. 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. Tapered ACFoam
® -III contains between
3.9% and 10.9% recycled materials by weight.
Manufactured and tested for use in new and re-roofing applications. Tapered ACFoam ® -III is used in built-up (BUR), modified bitumen, 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.
Tapered ACFoam ® -III 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 Tapered ACFoam ® -III insulation. Refer to PIMA Technical Bulletin 109: Storage and Handling Recommendations
for Polyiso Roof Insulation. 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.
