Huntsman Building Solutions Heatlok® HFO High Lift Closed-Cell Spray Foam Insulation Set (HS200-00WDU)
Heatlok HFO High Lift Closed-Cell Spray Foam Insulation
Heatlok® HFO High Lift is a closed-cell spray foam insulation formulated to deliver an aged R-value of about 7.4 per inch while allowing up to a 6.5 in. lift per pass to help meet ceiling code faster. It leverages Honeywell Solstice® HFO technology for ultra-low global warming potential and is designed for strong adhesion, good yield, and efficient application.
Key Features:
- High R-Value Performance: Aged thermal resistance of ~R-7.4 per inch (depending on installed thickness).
- High-Lift Application: Sprays up to 6.5 in. per pass to reduce labor time and speed code compliance.
- Moisture & Vapor Control: Tested WRB performance and functions as a Class II vapor retarder at 2 in. thickness.
- Code & Resiliency Credentials: NFPA 285 tested behind multiple claddings and meets FEMA Class 5 flood damage resistance requirements.
- Low-Impact Formulation: Uses Solstice® HFO blowing agent technology (GWP 1) and is GREENGUARD Gold certified (low VOC).
