What Firestable Insulation Company does

Firestable Insulation Company is a Connecticut-based fire technology manufacturer that has commercialized a patented, NFPA 275 certified closed-cell spray polyurethane foam (SPF) sold under the brand FS 2.0. The product is a two-component, MDI-based, water-blown system that delivers up to R-5 per inch while functioning simultaneously as insulation, air barrier, moisture vapor retarder, and thermal barrier in a single application — eliminating the post-applied thermal barrier (gypsum, intumescent coatings) that conventional SPF requires. Monolithic fire performance throughout the foam volume, ASTM E119 temperature transmission compliance, and QAI NFPA 275 certification combined with IAPMO Evaluation Report ER 0857 give the product direct code compliance under IBC, IRC, and IECC without special approval processes. A complementary Stablebase 2.0 Max R Closed Cell SPF product enables hybrid systems for projects requiring higher total R-values at lower cost.

The company's business model is B2B channel sales through a national distribution agreement with Service Partners (75+ branches), supported by an approved sprayer network of certified applicators across more than 30 U.S. states and a Level 1 Authorization training program. Firestable targets four primary customer segments: architects (who specify insulation and fire-safety materials and receive dedicated specification support), builders and contractors (who install via the certified sprayer program), data centers and mission-critical facilities (where high R-value, monolithic fire protection, and tight production schedules are critical), and homeowners (a secondary segment reached through the same channel). Pricing is quote-based rather than list-published, with multi-year contracts and a documented board-foot coverage of 5,000 bft/kit providing the principal unit economics signal.

Commercial validation includes BDC 75 Top Products 2023, Walls & Ceilings Most Requested Products 2023, a CCR Magazine Project Profile Award in 2024, and feature articles in Construction Specifier and Metal Construction News. The company operates with 11–50 employees from a single headquarters in Essex, Connecticut, is privately held with no disclosed institutional funding, and is a member of the Modular Building Institute, QAI, IAPMO, and the Spray Foam Coalition.

Revenue model

1. SPF Insulation Product Sales: Firestable generates revenue through the sale of its proprietary FS 2.0 NFPA 275 Thermal Barrier SPF product, sold as a two-component kit through its distributor network (Service Partners). The product is sold to authorized/installing contractors who then apply it to end customers. Additional related products include Stablebase 2.0 Max R Closed Cell SPF for hybrid systems.

Core offering

Firestable Insulation Company manufactures and sells the FS 2.0, the only NFPA 275 certified thermal barrier spray polyurethane foam (SPF) insulation on the market. The two-component, self-adhering, spray-applied system delivers up to R-5 per inch and provides insulation, air barrier, moisture vapor retarder, and thermal barrier performance in a single application without additional coatings or gypsum. It is sold through the Service Partners distributor network and installed exclusively by Firestable-authorized spray foam applicators for use in commercial, residential, data center, and mission-critical facility construction.

Product overview

Firestable Insulation Company offers a single primary product line centered on the Firestable FS 2.0, an NFPA 275 certified thermal barrier spray polyurethane foam. The FS 2.0 is available in Cloud White and Charcoal color variants and is MDI-based. The company also provides FS 2.0 A-Side (ISO component) as part of the system. Optional hybrid systems combine FS 2.0 with Stablebase 2.0 Max R Closed Cell SPF for cost-sensitive projects requiring higher total R-values. The company offers supporting services including sprayer certification, rig certification, architectural support, and inspector liaison programs.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Elastochem (Specialty Polymers / SPF): Elastochem manufactures specialty spray polyurethane foam insulation and coatings for the North American building envelope market, with partial overlap to Firestable's FS 2.0 in fire-rated / high-R closed-cell SPF. Smaller scale than the major incumbents, Elastochem is a credible adjacent niche competitor.

Broad incumbents

• Carlisle Spray Foam Insulation: Carlisle Construction Materials offers spray polyurethane foam insulation (closed-cell) for commercial and residential applications, directly competing with Firestable's FS 2.0. As part of a broader building envelope portfolio (roofing, waterproofing), Carlisle brings cross-selling and incumbent channel relationships that Firestable must match with certification depth.
• BASF (Spraytite / Walltite SPF): BASF manufactures Spraytite and Walltite closed-cell SPF systems for building envelope insulation, directly competing with Firestable's FS 2.0. As a major chemical incumbent, BASF has vastly larger R&D capacity, raw material positions, and code relationships — making it the most credible potential NFPA 275 challenger.
• Covestro (Baymer / SPF raw materials): Covestro is a major polyurethane raw materials supplier (MDI, polyols) and produces SPF systems, making it both a potential upstream supplier and direct competitor to Firestable's MDI-based FS 2.0. The chemical incumbent position and formulation IP portfolio make Covestro the most likely competitor to develop an NFPA 275-certified alternative.
• GAF EnergyGuard (SPF Insulation): GAF, one of North America's largest roofing and building envelope manufacturers, offers EnergyGuard closed-cell SPF insulation, directly competing with Firestable in the commercial and residential insulation market. GAF's broader roofing portfolio gives it material cross-sell advantages that Firestable lacks.

Direct peers

• NCFI Polyurethanes: NCFI manufactures spray polyurethane foam insulation systems (InsulStar and others) for residential, commercial, and industrial applications, directly competing with Firestable. NCFI shares Firestable's GTM motion of certified applicator networks and distributor partnerships.
• Johns Manville (Corbond SPF): Johns Manville manufactures Corbond closed-cell spray polyurethane foam insulation for residential and commercial applications, directly competing with Firestable's FS 2.0. JM is owned by Berkshire Hathaway and operates with broader product depth, but competes head-to-head with Firestable on R-value, code compliance, and contractor certifications.
• Huntsman Building Solutions (Heatlok / Icynene-Lapolla): Huntsman Building Solutions is one of the largest manufacturers of spray polyurethane foam insulation (closed-cell and open-cell), directly competing with Firestable's FS 2.0 across residential and commercial construction. Both sell through distributor networks and authorized applicator programs, with overlapping target customers (builders, contractors, architects).
• Ses Foam: Ses Foam is a U.S. manufacturer of polyurethane spray foam insulation systems for residential and commercial markets, directly competing with Firestable's FS 2.0 closed-cell SPF. Like Firestable, Ses Foam emphasizes R-value and code compliance in its positioning.
• Demilec (Heatlok High Lift / APX): Demilec manufactures Heatlok High Lift and other closed-cell SPF systems for the U.S. building insulation market, directly competing with Firestable. Both products target thermal barrier / ignition barrier compliance and are sold via certified applicator networks with distribution partnerships.
