PART 2 PRODUCTS
2.1 MANUFACTURERS
A. Provide products of Foam Enterprises, Inc., 13630 Water Tower Circle, Minneapolis, MN 55441. ASD. Tel: (800) 888-3342. Fax: (612) 559-0945.

NOTE ** Delete paragraph above or below. Edit Section Number as required for project.
C. Submit requests for substitutions in accordance with provisions of Section 01600.
2.2 MATERIALS
NOTE ** Most published data is run on laboratory produced samples, not in-place material. The thickness of polyurethane foam sprayed, number of passes, temperature of substrate, ambient temperatures, etc., all affect properties. The following values are for Foam Enterprises' product in-place.
A. Foam: Sprayed-in-place two-component closed-cell polyurethane made by combining an isocyanate (A) component with a polyol (B) component, with the following physical characteristics:
1. Density in place, when tested in accordance with ASTM D 1622: 1.7 to 1.8 lb/cu ft (27 to 29 kg/cu m).
2. Compressive Strength, when tested in accordance with ASTM D 1621: 20 to 30 psi (1.4 to 2.1 Pa), minimum.
3. Closed Cell Content, when tested in accordance with ASTM D 2856: 87 percent, minimum.
4. R-value, aged: 6.8.
NOTE ** From a fire safety standpoint, polyurethane foams can be used safely. It is important, however, that all persons associated with the design, fabrication, storage and installation understand the materials and environments involved.
NOTE **
NOTE ** Polyurethane foam insulation is combustible and should be treated as such. Flame spread ratings provided for polyurethane products using small scale tests are not intended to reflect the hazards presented by this or any other materials under actual fire conditions. Care must be taken to ensure that the foam is not exposed to heat or flame.
5. Flame Spread Index, when tested in accordance with ASTM E 84: Less than 75.
6. Smoke Developed Index, when tested in accordance with ASTM E 84: Less than 450.
B. Primers: As recommended by the manufacturer of the spray foam materials specified.
NOTE ** The following paragraph is for a vapor retarder coating to be applied directly to the foam. If the foam is to be covered by other construction, such as gypsum drywall, other types of vapor barriers can be used -- specify them in another section.
C. Vapor Retarder: Fluid-applied coating, Lion Oil Co., Nokorde 706M; permeability of 0.01 perm or less, when tested in accordance with ASTM E 96, Method D.
NOTE ** A thermal barrier (fire resistive) is almost always required over polyurethane foam exposed on the interior of the building. Typically, the minimum thermal barrier is a material that constitutes 15 minutes of fire protection for the foam. Materials that have been used include sprayed cementitious or fiber material (such as fireproofing) and gypsum board.
NOTE **
NOTE ** Delete the following paragraph if the thermal barrier is not a coating and is specified in another section.
D. Thermal Barrier: Sprayed coating, W.R. Grace Zonolite 3306 or International Cellulose Ure-K; applied for fire resistance rating of 15 minutes.

3.3 FOAM APPLICATION
A. Do not begin application of foam until all preparation requirements have been completed.
B. Do not apply foam when the temperature is below or the humidity is above that specified by the manufacturer for ambient air and substrate.

3.4 VAPOR RETARDER INSTALLATION
A. Apply vapor retarder in accordance with building code requirements and the manufacturer's specifications and instructions.
B. Apply vapor retarder to the entire surface of the foam in a continuous film across corners and junctions.
NOTE ** Delete the following article if the thermal barrier is not a spray-applied coating.
3.5 THERMAL BARRIER APPLICATION
A. Allow vapor retarder to cure before the thermal barrier coating is applied. Repair damage and defects to the vapor retarder prior to the application of the thermal barrier.
B. Apply thermal barrier over entire surface of foam.
C. Allow thermal barrier to cure. Inspect for defects and repair defects prior to subsequent coats.
