Boosting Building Performance with Froth-Pak™ 200 & 630: Fast, Reliable Air Sealing and Insulation for Modern Construction
In today’s construction environment—where energy efficiency, durability, and occupant comfort are top priorities—builders need solutions that deliver consistent, high-performance results without slowing down schedules. DuPont™ Froth-Pak™ 200 and 630 spray foam systems meet those expectations by offering fast-reacting, Class-A fire-rated insulation and air sealing in a fully portable, contractor-ready kit.
Engineered for precision and ease of use, Froth-Pak™ helps create tighter, healthier, and longer-lasting building envelopes across residential, commercial, and industrial projects. With a 30-second cure time, 1-hour re-entry with ventilation, and high R-value performance, these systems provide efficiency and reliability that align with today’s demanding building codes and performance targets.
Professional-Grade Performance, Portable Convenience
Froth-Pak™ 200 and 630 are complete, self-contained two-component spray foam systems packaged with pressurized A & B cylinders, an ergonomic Insta-Flo™ gun/hose assembly, and anti-crossover nozzles. Each kit is Class-A Fire Rated, enabling it to be used safely across interior and exterior projects that require fire-resistant insulating materials.
Both systems feature:
- Fast 30-second cure time
- One-hour re-entry with adequate ventilation
- Minimal overspray and consistent flow
- On-ratio application for predictable results
- Spray thickness up to 2 inches per pass
The portability of these kits eliminates the need for large equipment, making them ideal for both small-scale repairs and larger continuous insulation applications.
Thermal Efficiency That Strengthens Building Envelopes
Froth-Pak™ delivers a high aged R-value of 6.2 per inch, helping reduce thermal bridging and energy loss in hard-to-insulate areas. When sprayed at 2 inches, the system achieves an R-value of 12.2.
Additional thermal and physical performance characteristics include:
- Nominal density: 1.75 lb/ft³
- Initial R-value: 6.7 per inch
- Low air leakage per ASTM E283 and E2178
- Water vapor permeance: as low as 0.3 perms at 2 inches
- Dimensional stability across hot, cold, and humid conditions
These properties support long-term energy efficiency, structural stability, and resistance to moisture-driven deterioration.
Creating Healthier Indoor Environments Through Air Sealing
Air leakage is one of the primary contributors to:
- Uncontrolled moisture
- Mold growth
- Drafts
- Energy loss
- Poor indoor air quality
Froth-Pak™ acts as both insulation and an air barrier, sealing penetrations, joints, cavities, cracks, and envelope intersections. It helps buildings meet airtightness requirements such as ACH standards and reduces the presence of moisture, allergens, mold, and rot.
Because the foam adheres to wood, metal, masonry, rigid foam, and drywall, it can be used across a wide range of substrates and structural conditions.
Versatile Applications for Residential, Commercial & Industrial Projects
Froth-Pak™ 200 and 630 are designed for use in:
- Roof/wall junctions
- Wall/attic transitions
- Flash-and-batt assemblies
- Basements & crawlspaces
- Electrical penetrations
- Mechanical & plumbing penetrations
- Parapet walls & roof perimeters
- Gaps, cracks, cavities, and expansion joints
The foam’s rapid curing allows contractors to move quickly through complex building assemblies without extended wait times.
Environmental Responsibility and Code Compliance
Froth-Pak™ systems are formulated without ozone-depleting chemicals or HFCs and comply with modern environmental and building standards, including:
- GreenCircle® Certification
- LEED v4 compliance
- ICC ESR-3228
- UL Classification (R7813)
These designations support building performance goals and simplify code approval processes.
Choosing Between Froth-Pak™ 200 and 630
| Product | Theoretical Yield* | Kit Weight | Ideal Use Case |
| Froth-Pak™ 200 | 200 board ft | ~39 lb | Small to medium jobs, patching, targeted air sealing |
| Froth-Pak™ 630 | 630 board ft | ~111 lb | Larger-scale insulation, continuous air sealing, whole-room applications |
*Based on 1" thickness under ideal laboratory conditions. Actual yield varies depending on temperature, nozzle type, and application method.
Safety, PPE, and Best Practices
Froth-Pak™ is intended for licensed/professional applicators. Installers must use:
- Full protective clothing (e.g., Tyvek® suit)
- Chemical-resistant gloves
- Goggles or full-face protection
- NIOSH-approved respirator (organic vapor + P100)
- PPE for all workers within 25 feet of the spray zone
