Nailable Roof Insulation
DESCRIPTION: Thermally efficient closed-ce ll ACFoam®-11 or ACFoam®-1 11 polyisocyanurate (polyiso) insulation board bonded to min. 7/16" APA/TEC O rated OSB or
min. 19/32" COX plywood on the top face. ACFoam® Nail Base is offered in a variety of composite thicknesses, providing long-term thermal resistance
(LTTR) values from 6.3 to 24.2. Made to order in 4ft x Bft (1220mm x 2440mm) panels with a nominal thickness of 1.5" to 4.5". Manufactured in
accordance with ASTM C1289, Type V.
ADVANTAGES: ACFoam® Nail Base combines the benefits of a nailable roof substrate and thermally efficient polyiso insu lation in an easy one-step installation.
Available as a special order product with FSC® Certified, Fire-Treated, Preservative-Treated OSB or COX. ACFoam® Nail Base is manufactured using
CFC-, HCFC-and HFC-free foam blowing technology with zero ozone depletion potential (OOP) and virtually no (negligible) global warming potential
(GWP). ACFoam® Nail Base contains between 52.9% and 28.9% recycled materials by weight (Atlas Technical Bulletin: 18-2)
APPLICATION: Approved for use as a non-structural panel in new and re-roofing applications. ACFoam® Nail Base is typically installed over sloped solid-wood
and metal roof decks. Deck slope must be appropriate for the type of roof system specified. Typical roof systems include asphalt shingles, standing
seam metal, tile and slate. ACFoam® Nail Base is not designed or approved for vertical application. The architect, engineer or design professional is
responsible for determining the need for and location of a vapor/air retarder.
INSTALLATION: Atlas requires mechanical attachment of Atlas ACFoam® Nail Base with Atlas Nail Base Fasteners to approved
structural roof decks. ACFoam® Nail Base shall be kept dry before, during and after installation. This product will bu rn if exposed to an ignition
source of sufficient heat and intensity. Do not apply flame directly to AC Foam® Nail Base insulation. Refer to product packaging and PIMA Tecfiflical
Bulletin #109 for storage and handling recommendations. Suitable for multi-layer assemblies when installed over Atlas ACFoam®-11, or -Ill and
through-fastened with Atlas Nail Base Fasteners. Refer to #a1/a/Jle Insulation Cu/de for fastening guidelines and installation recommendations.
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.
