Huntsman Building Solutions Heatlok® HFO High Lift Closed-Cell Spray Foam Insulation (HS200-00SDU)
Heatlok HFO High Lift Closed-Cell Spray Foam Insulation
Heatlok® HFO High Lift is a closed-cell spray foam insulation designed for fast, high-lift application with strong thermal performance (aged R-7.4 per inch). Formulated with an ultra-low GWP blowing agent (GWP 1), it delivers improved yield and adhesion while helping reduce VOC impact for indoor environments.
Key Features:
- High R-Value Performance: Delivers aged thermal resistance of 7.4 per inch (depending on installed thickness).
- High-Lift, Faster Coverage: Sprays up to a 6.5 in lift per pass to help meet ceiling insulation code faster and reduce labor time.
- Ultra-Low GWP Technology: Uses Honeywell Solstice® HFO blowing agent technology with GWP of 1 (99.9% lower than traditional blowing agents).
- Moisture & Vapor Control: Tested as a water-resistant barrier (WRB) and functions as a Class II vapor retarder at 2 in thickness.
- Cleaner Indoor Profile: GREENGUARD Gold certified and described as low-VOC for sensitive environments like schools and healthcare facilities.

Frequently Asked Questions (FAQ):
Q: What type of insulation is Heatlok HFO High Lift?
A: It is a closed-cell spray polyurethane foam (SPF) insulation system.
Q: What R-value does it provide?
A: It lists aged thermal resistance of 7.4 per inch (often referenced as R-7.4/in), depending on installed thickness.
Q: How thick can I spray in one pass?
A: It is designed for high-lift application up to a maximum 6.5 inches per pass.
Q: Does it help with moisture control?
A: It is listed as a tested water-resistant barrier (WRB) and a Class II vapor retarder at 2 inches thickness.
Q: What makes it lower environmental impact than older spray foams?
A: It leverages an HFO blowing agent technology with a stated GWP of 1, significantly lower than traditional blowing agents.
A quiet, seamless envelope for elevated comfort
Great spaces feel effortless—warmth held close, drafts erased, and surfaces that read clean and composed. Heatlok® HFO High Lift builds that invisible luxury with a high-performing, closed-cell layer that can be sprayed thick in a single pass for a truly continuous envelope. Use it where you want architectural calm—attics, rim joists, and foundations—so the design you see isn’t interrupted by the comfort you feel. It’s the kind of behind-the-walls upgrade that makes everyday living feel undeniably refined.
Upgrade your building envelope with Heatlok® HFO High Lift for fast, high-R closed-cell performance with ultra-low GWP technology.
