PART 2 - PRODUCTS
2.1 MANUFACTURER
A. Air krete, Incorporated:
See Editing Instruction No. 1 in the Evaluations for cautions about naming manufacturers and products.
Edit this Article with other Part 2 articles in which manufacturers and products, or manufacturers only, are named. See Division 01 Section "Product Requirements" for an explanation of the terms "Available Products," "Products," "Available Manufacturers," and "Manufacturers" and the effect these terms have on "Comparable Product" and "Product Substitution" requirements.
1. P.O. Box 380, Weedsport NY 13166-0380 –Keene Christopher, Principal Telephone: (315) 834-6609
Delete types of insulation not required from articles below that specify insulation. Coordinate selections with thicknesses indicated on Drawings and with HVAC design and energy program. Where insulation is exposed or open to air spaces in plenums, cavities, or similar voids, include only products that comply with building codes for fire-test-response characteristics. Surface-burning indexes indicated for foam-plastic insulation are examples only and generally represent maximums allowed by model building codes for foam-plastic insulation. Revise to suit products required and code in effect for Project. See Evaluations.
In articles below specifying insulation products, coordinate subparagraphs that introduce a list of manufacturers or manufacturers and products with Part 2 "Manufacturers" Article. Retain "Available" for nonproprietary and delete for semi proprietary specifications.

First paragraph below describes products intended for below-grade applications. Verify whether manufacturer's insulation board is suitable for soil pressures to which it will be exposed. See product list in Evaluations. Delete if this product is specified in other Sections, such as Division 33 Section "Sub drainage" and Division 07 waterproofing Sections.
PART 3 - EXECUTION
3.1 EXAMINATION
A. Prior to beginning work, examine substrates and conditions, with Applicator present, for compliance with requirements of Sections in which substrates and related work are specified, and for other conditions affecting application, performance, and compatibility.
1. Proceed with installation only after unsatisfactory conditions have been corrected.
3.2 PREPARATION
A. Clean substrates of substances harmful to foamed cementitious insulation, retention fabric, vapor/weather retarders, and attachments, including removing projections capable of puncturing vapor/weather retarders or interfering with foamed cementitious insulation attachment.
1. Insure heat producing devices and elements that are not inherently fireproof are shielded such that insulation will be held 3” away.
B. Utilize drop cloths, masking and other protections as suggested by the manufacturer to prevent damages to adjacent surfaces and/or material.
3.3 INSTALLATION, GENERAL
A. Comply with insulation manufacturer's written instructions applicable to products and application indicated.
B. Install insulation that is undamaged, unsoiled and insulation that has been stored, shipped and handled as per manufacturer's written instructions.
C. Foamed cementitious insulation shall be installed when the combination of indoor and outdoor temperatures is such that the temperature at the point of application is 40 degrees Fahrenheit and rising during the application process and during the initial 48 hour curing process.
D. Utilize enclosures with heat when necessary, to maintain temperature through initial curing.
E. Provide adequate ventilation as required by the manufacturer’s written instructions to properly cure the insulation during and subsequent to it’s application.
F. Apply insulation in locations and thicknesses as indicated in the construction documents.
G. Mixing: Component materials shall be mixed using the quantities, proportions and the pressures called for in the manufacturer’s instructions for the purpose intended.
H. Support Attachments: Install where required by Manufacturer using either electric stapler or air stapler. Staple crown width 1/2” minimum, depth 3/8”.
I. New Masonry: Completely fill block cores and cavities between wythes in lifts not to exceed 8’-0”.
J. Retro-fit Masonry: Access between wythes with holes center each way; fill cavities completely; plug holes with non-shrink mortar to match existing. Consult manufacturer for retrofit core filling.
K. New Stud Spaces: Apply retention fabric, attaching as required to prevent sagging or deformation; foam stud cavity completely full, leave interior finish (or vapor/barrier when required) off until foam has initially cured.
L. Retro-fit Stud Spaces: Access spaces 12’-0” or less in height at a point two-thirds of their height above their bottom. Higher spaces shall be accessed such that no lift exceeds 8’-0”. Fill spaces completely and plug holes after foaming with material to match existing.
M. Ceiling Spaces: Fill to depth shown in a manner similar to that specified for stud spaces. Where a vapor/weather barrier may be required, the applicator must receive the manufacturer’s approval to use the vapor/weather barrier as a retention fabric.
N. Pipe Chases: Fill completely after all required inspections and tests have been performed satisfactorily.
O. Miscellaneous: Consult manufacturer for fire-proofing, encapsulation, very high temperature and sound deadening application instructions.
Insert specific protection requirements here.
3.4 ON-SITE QUALITY CONTROL
A. Density: Conduct a timed, field density check at the beginning, middle and end of each day’s application. The density check shall be done in accordance with the manufacturer’s instructions and a log of results maintained for the architect’s review.
B. Continuity: At the Architect, or Owner’s discretion, an infrared thermo graphic test may be requested.
1. If the test proves compliant with specified performances, the Owner will bear the test cost.
2. If the test proves non-compliant with specified performances, the cost of the test, along with the cost of correcting the non-compliant items.
Retain this Article or, as an alternative, a tabular schedule on Drawings if multiple types of insulation are required for Project and the method of noting which types of insulation are required in specific locations uses numbered insulation types rather than descriptions of insulation products.
