DuPont Froth-Pak 630 Foam System
Among the two-component listings we tracked on September 8, 2026, this one carried the largest Amazon buying signal: fifty-five ratings and a "100+ bought in past month" badge on the 15 ft version.
The claim, in the maker's words
"Froth-Pak 630 Insulation and Sealant covers 630 square feet at 1 inch thickness. Provides an R-value of 6.2 at 1 inch thick and 12.2 at 2 inches thick." Nothing on this page was sprayed or tested by us. Every figure names the document or listing it came from, and where the maker publishes nothing the row says so rather than staying blank.
What DuPont states, and on what basis
| Kit sizes | One kit with the same contents as the 200 and a 15 ft gun hose assembly; a 30 ft assembly version is sold on Amazon |
|---|---|
| Stated yield | 630 sq ft at 1 inSame theoretical-yield definition as the 200 |
| R-value | R-6.2 per inch; 12.2 at 2 inSame as the 200: "aged LTTR measured at 2-in. thick" on the page; ASTM C518, aged 180 days at 75 F at 1 in and 2 in, on the Product Information SheetTwo published results at two thicknesses, on the same basis as the 200 kit: each measured at its own sprayed thickness. |
| Fire | Class A fire rated up to 2 in thick on the page; ICC-ES ESR-3228 gives flame spread 25 or less and smoke developed 450 or less at a maximum of 2 in; the exact indices are not published |
| Vapor | 5.4 perm at 1 in and 3.1 perm at 2 in, ASTM E96 |
| Cure | Product page: 30-second cure time and 1-hour re-entry with proper ventilation. Operating manual, Rev 04/2026: tack free within 60 seconds, fully cured in five minutes |
| Hose | 15 ft; 30 ft version listed on Amazon |
| Reuse | Reusable for 30 days after opening. The operating manual states storage temperatures but no shelf-life duration. |
| Protective equipment | As the 200: coveralls, eye protection, organic vapor/P100 respirator, chemical-resistant gloves |
| Who the maker says it is for | "Particularly well-suited for bigger applications such as larger renovation projects or cold storage insulation" |
Cost against the yield the maker itself states
One row per kit size where a single price maps to a single stated yield. The unit is the maker's own: DuPont states square feet at a thickness and HandiFoam states board feet. At a stated 1-inch thickness the two are the same volume, so 200 sq ft at 1 in equals 200 nominal board feet; that conversion keeps the maker's theoretical-yield basis and predicts nothing about field yield. Prices are the September 7, 2026 snapshot. Prices are snapshots, each dated where it appears, not live figures, so check the seller before you pay.
| Kit | Price | Stated yield | Per stated unit | Channel |
|---|---|---|---|---|
| 630 kit, 15 ft hose | $989.00 | 630 sq ft | $1.57 per sq ft | Amazon |
Our reading
Among the two-component listings we tracked on September 8, 2026, this one carried the largest Amazon buying signal: fifty-five ratings and a "100+ bought in past month" badge on the 15 ft version. Per stated square foot it is cheaper than the 200: $989 for 630 sq ft against $409 for 200 sq ft, about $1.57 against $2.05 per theoretical square foot. Same documents as the 200, and the same missing E84 indices.

Questions and answers
Questions about DuPont Froth-Pak 630 Foam System
Answered from this product’s documents and listings, the same records the rest of this page is built from.
-
What does DuPont claim the Froth-Pak 630 covers? From the records
630 sq ft at 1 in Same theoretical-yield definition as the 200
-
Does DuPont publish a data sheet for the Froth-Pak 630? From the records
Yes. Froth-Pak Foam System Product Information Sheet, 2025.
-
Can the Froth-Pak 630 be left exposed? From the records
Not as a general rule, whatever its fire class. The 2021 IRC asks for a thermal barrier between foam plastic and the interior of the building, and a Class A surface-burning result is not that barrier. The code carries narrow exceptions that depend on the exact product and the assembly: an ignition barrier instead of a thermal barrier in attics and crawl spaces entered only to service utilities (R316.5.3 and R316.5.4), and the sill plate and header exception (R316.5.11) where installed thickness, density and both surface-burning indices meet its limits. Whether this kit qualifies for one is a question for its own documents and your local authority.
A Class A surface-burning result does not let the foam stay bare. The 2021 IRC asks for a thermal barrier between foam plastic and the interior of the building, with a narrower ignition barrier rule for attics and crawl spaces entered only to service utilities, and the band joist is a third case with numeric limits of its own. The hub page sets out which rule applies where. Read the rating method and our editorial policy.
