• New ASHRAE 2010 Standard includes
significant requirements for non-residential
wall insulation.
• Prescriptive minimum values are increasing
across all North American Climate zones
ASHRAE Standard 90
• Standard 90: Prepared by member review
and consensus agreement as defined by
ANSI (American National Standards
Institute)…
• “To provide minimum requirements for
the energy efficient design of buildings
except low rise residential buildings.”

Polyiso Optimizes Building Efficiency
• Increased focus on High Performance in the
total Building Envelope
• Mandated Higher R-values at Federal & State
levels for Public buildings
• Legislation aimed at improving energy
efficiency in the built environment.
• Polyiso used as “exterior continuous
insulation” (ci)
“c.i.”
Continuous insulation:
Insulation that is continuous across all structural
members without thermal bridges other than
fasteners and service openings. It is installed on the
interior, exterior, or is integral to any opaque
surface of the building envelope.

IBC Chapter 26
Chapter 26 of the IBC: Foam Plastics.
All foam insulation is required to meet
the standards in this chapter of the
International Building Code.
NFPA 285
NFPA 285: National Fire Protection Association.
285 is a multi-storey wall assembly fire test
required by code for commercial buildings Type I,
II, III and IV construction. The assemblies include
all products from interior finish to exterior
cladding. It is a pass/fail test.

Glossary of Terms
• WRB: Weather Resistive Barriers. This is a
generic description of barriers used in wall
assemblies. It could refer to Air, Moisture
or Vapor.
• AVB: Air and Vapor Barrier. Must resist air
leakage. Available as a spray on, peel and
stick, sheet goods. Type of air barrier, and
position in assembly is determined by
climate and architect.
