-
- 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.

- ambient air and substrate.
-
- C. Apply foam in accordance with the manufacturer's

- coating. Delete if a sheet-type vapor retarder is
- used.

- requirements and the manufacturer's specifications and
- instructions.
-

- 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
