ICYNENE MD-R-200

ICYNENE MD-R-200^™represents a revolution in medium density insulating spray foam and air barrier materials. It’s an ideal choice for those who want a more eco-friendly option than closed-cell insulating spray foam, but a higher R-value, compressive strength and tensile strength than what is offered by most open-cell insulating spray foam. Icynene MD-R-200 is guaranteed to perform as specified for the life of the building

Performance Benefits

• Stable thermal performance.
• R-value = 5.2 per inch
• Water blown
• Low permeance Class 3 VDR (1.8 perm @3" thick)
• Rigid, not flexible composition contributes to wall racking strength.
• Rejects bulk water
• Supports indoor air quality by blocking air infiltration and mass transfer of moisture that may cause mold.

Characteristics

• Closed-cell structure
• Synthetic blown
• Medium density 2.0 lb.
• HFC- and PBDE-free
• Rigid to touch
• Expands 60 times from liquid state
• Apply in 2" lifts
• Will not harm coatings on electrical wiring, plumbing or other building components
• Approved for construction type: V
• Lowest global warming potential (GWP of 1)
