ACFoam-II is typically specified for hot asphalt or coal tar BUR,
modified bitumen, metal and single-ply membrane systems. ACFoam-II has
one side marked for hot BUR and modified bitumen applications and one
unmarked side for single ply and cold-applied modified bitumen
applications, making this an almost universally adaptable product
suitable for a variety of applications. ACFoam-II is a closed-cell,
polyiso core integrally laminated to heavy black (non-asphaltic),
fiber-reinforced felt facers. ACFoam-II is also available in 25-psi
formula. Available in 4´ x 4´ (1220mm x 1220mm) and 4´ x 8´ (1220mm x
2440mm) panels.

In response to valid concerns of building
designers regarding thermal efficiency of roof assemblies and the
long-term insulating value of roof insulation, Atlas offers a 20-year,
limited thermal warranty. The "ACFoam" Limited Warranty places Atlas
ACFoam products above all others and supports the building owner,
designer and contractor by backing up thermal performance. This
warranty is available to the building owner at the time the building
is completed and is transferable to any subsequent owner for the
duration of the 20-year period.
20
Year Limited Warranty
Storage/Precautions: Factory-applied
packaging is intended only for protection during transit. When stored
outdoors or on the job site, packages should be stacked on pallets at
least four inches above ground level and completely covered with a
weatherproof covering such as a tarpaulin. The temporary
factory-applied packaging should be slit or removed to prevent
accumulation of condensation. Roof insulation which has become wet or
damaged should be removed and replaced with solid, dry insulation.
Warning! Do Not Leave Exposed: This
product is a polyiso organic plastic foam and will burn if exposed to
an ignition source of sufficient heat and intensity, or open flame,
such as a welder´s torch. Like other organic materials, this product
will release smoke if ignited. Do not apply flame directly to ACFoam
roof insulations. This product should be used only in strict
accordance with Atlas recommended uses and application instructions.

ACFoam® General Installation
Instructions
Before installation begins, the roof deck should be firm,
well attached, even, clean and dry. Proper attachment of the
insulation is necessary to prevent roof failures. Atlas will not be
responsible for any damage caused by improper attachment. Atlas Roof
Insulation products can be attached to decks that are approved by
Factory Mutual and local codes. Atlas is not responsible for
determining the suitability of the deck. ATLAS ROOF INSULATION
PRODUCTS SHALL BE KEPT DRY BEFORE, DURING AND AFTER INSTALLATION.
Although Atlas Roof Insulation has been designed to withstand normal
foot traffic, protection from damage by construction traffic and/or
abuse is extremely important. Roof surface protection such as plywood
must be used in areas where storage and staging are planned and heavy
or repeated traffic is anticipated during or after installation.
(See Technical Bulletin #00-01)
Moisture/Vapor Control
Vapor retarders are used to impede the passage of water vapor
into roofing systems, thereby preventing condensation and resulting
damage to the insulation and roof system. All Atlas Roof Insulation
Products may be installed with or without a vapor retarder, the need
for which is determined by the designer. The designer may consult the
NRCA Roofing and Waterproofing Manual for guidance in determining the
need for a vapor retarder. Special consideration should be given to
construction-generated moisture, as well. For
example, construction-generated moisture, such as will be released by
placing concrete floor slabs after the roof has been installed, can
drive large quantities of moisture into the roof system. Therefore,
Atlas cannot be responsible for damage to the insulation when exposed
to construction-generated moisture. Refer to the NRCA Roofing and
Waterproofing Manual for their recommendations for the use of a vapor
retarder when construction-generated moisture is present (4th Edition,
Volume 1, p. 121). Refer to Atlas
Technical Bulletin #00-01.
