Huntsman Building Solutions: products and EPD coverage
Huntsman Building Solutions is best known for spray foam insulation, but their catalog also spans roofing coatings and specialty foams. If a project team asks for product‑specific EPDs, which lines are covered today and which ones might still need attention to avoid last‑minute substitutions?
Who they are and what they make
Huntsman Building Solutions (huntsmanbuildingsolutions.com) emerged from legacy spray foam brands and now focuses on building‑envelope performance. The portfolio centers on open‑cell and closed‑cell spray polyurethane foam for walls and roofs, with add‑ons like injection foams, high‑temperature and geotechnical foams, and roof restoration coatings. Across regions and formulations, the number of individual SKUs is in the dozens.
Product families at a glance
Most activity sits in two insulation families. Open‑cell foams such as FOAM‑LOK 450 and 500 target speed and sound control. Closed‑cell Heatlok lines (HFO Pro, High Lift, XT High Yield, and localized variants) target high R‑value per inch, air and vapor control, and NFPA 285 assemblies. Beyond insulation, Huntsman lists silicone and acrylic roof coatings like Thermo‑Sil 2200 for restoration work.
Where EPDs exist today
Insulation is the bright spot. Huntsman has product‑specific, third‑party EPDs covering open‑cell spray foam in Europe under EPD International S‑P‑07946 (valid through 2027) and closed‑cell Heatlok HFO in Europe under S‑P‑07866 (valid through 2027) (EPD International, 2025, EPD International, 2025). In North America, Huntsman previously announced UL‑certified EPDs for Heatlok HFO systems, confirming program‑operator publication and verification in that market (HBS Newsroom, 2021).
Coverage gaps worth watching
Roof coatings appear less covered by publicly registered EPDs. As of December 25, 2025, we could not find program‑operator listings for Thermo‑Sil silicone coatings on major registries. Meanwhile, competing roof‑coating lines do have EPDs available, for example UNIFLEX silicone roof coatings are listed by NSF with validity into 2028 (NSF, 2023). If a spec calls for an EPD on a coating package, that difference can decide which submittal clears the sustainability screen first.
Competitor set on typical projects
Spray foam projects often see Carlisle Spray Foam Insulation on bid lists, and Carlisle markets product‑specific EPDs for open‑cell formulations that a specifier can download from product pages (Carlisle, 2023). In substitution scenarios, SPF may compete with other insulation systems from firms like Johns Manville, Owens Corning, or CertainTeed that publish many product EPDs across blankets, boards, and membranes. On restoration roofs, silicone and acrylic coating brands with published EPDs can also show up as alternatives.
Why this matters commercially
LEED v5 keeps the spotlight on product‑specific EPDs as proof of third‑party verified impacts. When a product lacks one, teams often default to conservative assumptions that add embodied‑carbon “penalty” in their accounting. That can nudge a buyer toward a comparable product that brings its own EPD, even if performance is similar. The cost of producing an EPD is frequently offset by a single mid‑sized win where the documentation removes friction and keeps the spec intact.
Fast wins for Huntsman’s roadmap
Focus on the high‑runner SKUs in each family and close coating gaps first. A silicone topcoat EPD aligned to the common roof‑coatings PCR would unlock restoration programs that now prefer or require verified disclosures. For insulation, maintain cadence so renewals do not bunch up, and consider adding regionalized results where plants and blends differ materially. Keep the bill‑of‑materials data collection painless for operations. That is where teams usually lose weeks.
Sustainability story, told simply
Huntsman’s sustainability page highlights recycled PET use in foam polyols and long‑term energy savings from the building envelope. If that narrative is paired with fresh, program‑operator EPDs for the remaining lines, it reads as a complete specfication package that helps project teams move quickly. See their overview here (HBS Sustainability, 2025).
What we would monitor next
Two signals are worth tracking. First, any new UL, Smart EPD, or EPD International publications for Huntsman roof systems and coatings. Second, competitor pushes in SPF with portfolio‑wide EPDs that make submittals almost plug‑and‑play. If those show up on the same project, having Huntsman documents ready means less time defending a substitution and more time closing the sale. It really is that simple, even if teh acronyms make it feel complex.
Frequently Asked Questions
Does Huntsman Building Solutions publish product-specific EPDs for spray foam insulation?
Yes. Open‑cell and closed‑cell spray foam lines have product‑specific EPDs published with program operators. Examples include EPD International entries S‑P‑07946 for open‑cell foam and S‑P‑07866 for closed‑cell Heatlok HFO, both valid to 2027 (EPD International, 2025, EPD International, 2025).
Are Huntsman’s roof coatings covered by EPDs?
We did not find publicly listed EPDs for Huntsman roof coatings on major registries as of December 25, 2025. Competing silicone coatings do have listings, such as UNIFLEX entries on NSF valid to 2028 (NSF, 2023).
Which competitors often appear on the same bid lists?
For SPF insulation, Carlisle Spray Foam Insulation is common and publicly promotes product‑specific EPDs. In substitution scenarios, systems from Johns Manville, Owens Corning, and CertainTeed also compete, especially where EPD availability is a must.
