PRODUCT NAME Y N E N E FD� - f- - 5" ICYNENE LD-C-50® Is a trademark for light density, open celled, flexible,100% water -blown polyurethane foam insulation manufactured by Icynene Inc. ICYNENE LD-C-5011 spray formula Is a nominal 0.5 Ibs/fta density, free rise material. 2. MANUFACTURER ICYNENE LD-C-509 Is made on -site from liquid components manufactured by Icynene Inc. Installation and on -site manufacturing is supplied by Independent Icynene Licensed Dealers. 3. PRODUCT DESCRIPTION ICYNENE LD-C-5001 the "classic" light density formulation of Icynene has been Installed in buildings since 1986. Icynene is the pioneer of high yield, 100% water -blown polyurethane foam technology for air -sealing and insulating buildings. ICYNENE LD-C-5011 Insulates and air -seals In one step for maximum energy conservation while minimizing the environmental Impact during manufacturing and construction. Significantly reducing air leakage means ICYNENE LD-C-5011 contributes to a healthier, quieter and more comfortable Indoor environment, while reducing energy consumption and related greenhouse gas emissions by as much as 50%. ICYNENE LD-C-50® is an effective vapor permeable air barrier material that can move with the building to maintain the air barrier characteristic against energy -robbing air leakage for the life of the building. Convective air movement Inside wall cavities is virtually eliminated, providing more uniform temperatures throughout the building. The result Is superior quality construction, with higher comfort levels and lower heating and/or cooling costs. Energy savings will vary depending on building design, location, etc. ICYNENE LD-C-500 Is applied by spraying liquid components onto an open wall, crawlspace, telling surface or cathedral ceiling. There It expands approximately 100:1 In seconds to provide a flexible foam blanket of millions of tiny air cells, filling building cavities, cracks and crevices in the process. It adheres to most construction materials, sealing out air Infiltration. Excess material Is easily trimmed off, leaving a surface ready for drywall or other code - compliant finish. 4.

ICYNENE LD-C- 50® Is not subject to loss of R-value due to aging, windy! conditions, settling, convection or air Inflltration; nor will It be prone to traditional moisture Intrusion via air leakage. A FACT SHEET with R-value data Is available upon request.

See ASHRAE Standard 62 — Ventilation for Acceptable Indoor Air Quality. Water Vapor Permeance i ICYNENE LD-C-50® is water vapor permeable and, allows molsture to diffuse through the Insulation and dissipate from the building envelope. Water vapor transmission properties: (ASTM E96 Desiccant Method) - . II perms @ 5.5" In those situations that warrant a vapor retarder, asupplemental layer of polyethylene may be used. Alternately, low vapor permeance paint elther directly on the foam or as a primer for the Interior drywall may be used. Water Absorption Properties Water can be forced Into the foam under pressure because it Is open celled. Water will draln by gravity, given favorable drying potential, and upon drying all chemical and physical properties are fully restored.

Requirements for Thermal Barrier and Ignition Barrier coverings must be met as per the applicable building code having jurisdiction. U.S. Fire Testing Surface Burning Characteristics of (ASTM E841 @ 5" Thickness Flame Spread 525 Smoke Development -e450 *Flame spread rating not Intended to reflect hazards under actual fire conditions. Electrical Wiring ICYNENE LD-C-50® has been evaluated with energized 14/3 and 12/2 residential wiring (max. 1220F). It Is chemically compatible with typical electrical wiring coverings. Note: For any Insulation of knob and tube wiring, please reference local electrical code. Corrosion ICYNENE LD-C-5011 did not cause corrosion when evaluated In contact with steel at 120°F and 85% relative humidity conditions. ICYNENE LD-C-50® - USA Plastic Piping ICYNENE LD-C-50® Is compatible In direct contact with CPVC piping systems, as per Paschal Engineering Study for the Spray Polyurethane Foam Alliance (SPFA). Bacterial or Fungal Growth and Food Value Independent testing conducted by Texas Tech University has confirmed that ICYNENE LD-C- 50® Is not a source of food for mold; and as an air barrier material, It resists the airborne Introduction of moisture, nutrients, and mold spores Into the building envelope. Environmental / Health / Safety ICYNENE LD-C-500 is 100% water -blown and therefore contains no ozone -depleting blowing agents. It Is also PBDE-free. It has been thoroughly evaluated for in -situ emissions by Industry and government experts. VOC emissions are below 1/100th of the safe concentration level (TLV) within hours following the application of ICYNENE LD-C-50®. Proper handling and use is required to avoid exposure to reactive chemicals in their unreacted state. For more Information, contact the Spray Polyurethane Foam Alliance or the American Chemistry Council. Newly Insulated areas have been shown to be safe for occupancy 24 hours after Installation Is complete. ICYNENE LD-C-50® is CHPS E.Q. 2.2/Section 01350 Compliant and listed as such In the Collaborative for High Performance Schools (CHPS) Low Emitting Materials (LEM) Table. Under LEED guidelines, products that are CHPS E.Q. 2.2/Section 01350 Compliant are considered Environmentally Preferable Products. The reaction used to create ICYNENE LD-C-50® generates Carbon Dioxide to expand the foam. Carbon Dioxide has a very low Global Warming Potential (GWP of 1). Not Intended for exterior use. Not to be Installed within 3" of heat emitting devices or where the temperature Is In excess of 200°F, as per ASTM C411 or in accordance with applicable codes.
