2 Inch Dow Styrofoam Board: Polystyrene Insulation Board

2 Inch Dow Styrofoam Board: Polystyrene Insulation Board

2 Inch Dow Styrofoam Board Scoreboard insulation is an extruded polystyrene insulation board that is scored longitudinally on 16″ and 24″ centers, making it easy to size to commonly used widths. 2 Inch Dow Styrofoam Board Scoreboard has excellent insulating characteristics, high resistance to water and water vapor, superior compressive strength and long-term durability.

BASIC USE:
STYROFOAM™ Scoreboard insulation is designed for use in exterior cavity wall and foundation applications. Like all STYROFOAM extruded polystyrene products, STYROFOAM Scoreboard insulation resists moisture to deliver a stable R-value* over the long term.

APPLICABLE STANDARDS:
STYROFOAM™ Scoreboard meets ASTM C578, Type IV. ASTM C578 Standard Specification for Rigid Cellular Polystyrene Thermal Insulation

Includes:
• C518 – Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus
• D1621 – Standard Test Method for Compressive Properties of Rigid Cellular Plastics
• C272 – Standard Test Method for Water Absorption of Core Materials for Structural Sandwich Constructions
• E96 – Standard Test Methods for Water Vapor Transmission of Materials
• C203 – Standard Test Methods for Breaking Load and Flexural Properties of BlockType Thermal Insulation
• D2126 – Standard Test Method for Response of Rigid Cellular Plastics to Thermal and Humid Aging

CODE COMPLIANCE:
STYROFOAM™ Scoreboard insulation complies with the following codes:
• International Residential Code (IRC) and International Building Code (IBC) for foam plastic insulation; see ICC-ES NES NER report 699, BOCA-ES RR 21-02
• Underwriters Laboratories, Inc. (UL) Classified, see Classification Certificate D369 Contact your Dow sales representative or local authorities for state and local building code requirements and related acceptances.

PHYSICAL/CHEMICAL PROPERTIES:
STYROFOAM™ Scoreboard insulation exhibits the properties and characteristics indicated in Table 1 when tested as represented. For chemical resistance properties of STYROFOAM Scoreboard insulation, see Table 2. Exposure to ultraviolet radiation in sunlight for several
weeks will cause the surface of STYROFOAM Scoreboard insulation to become yellow and dusty. A light-colored, opaque protective covering should be used if excessive solar exposure is expected. The surface degradation will have no measurable effect on the insulating value of the plastic foam unless the deterioration is allowed to continue until actual foam thickness is lost. Since the dust would impair the performance of adhesives and finishes, the dusty surface should be brushed off before these products are applied.
