3. PRODUCT DESCRIPTION
STYROFOAM
™
Brand Scoreboard
Insulation is an extruded polystyrene
foam insulation board that is scored
longitudinally on 16” and 24” centers,
making it easy to size to commonly used
widths. STYROFOAM
™
Brand Scoreboard
Insulation has excellent insulating
characteristics, high resistance to water
and water vapor, exceptional compressive
strength and long-term durability.
Basic Use
STYROFOAM
™
Brand Scoreboard Insulation
is designed for use in exterior cavity wall
and foundation applications. Like all
STYROFOAM
™
Brand Extruded Polystyrene
products, STYROFOAM
™
Brand Scoreboard
Insulation resists moisture to deliver a
stable R-value* over the long term.

Physical Properties
STYROFOAM
™
Brand Scoreboard
Insulation exhibits the properties and
characteristics indicated in Table 2 when
tested as represented.
Exposure to ultraviolet radiation in
sunlight for several weeks will cause the
surface of STYROFOAM
™
Brand Scoreboard
Insulation to become yellow and dusty. A
lightcolored, opaque protective covering
should be used if excessive solar exposure
is expected. The surface degradation
will have no measurable eect 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 o before these
products are applied.
Environmental Data
