Welcome to our guide on RedDevil Polyurethane Foams, where you'll find premium spray foam sealants designed specifically for insulating and sealing gaps in homes, buildings, and industrial settings. With just two standout products in this category—the 0913 for small gaps and the 0909 for larger voids—these foams deliver reliable expansion, adhesion, and durability, making them essential for anyone tackling insulation challenges efficiently.

Why Choose RedDevil Polyurethane Foams?

RedDevil has built a strong reputation in the sealing and construction industry for producing high-quality polyurethane products that professionals and DIY enthusiasts trust. What sets RedDevil foams apart is their consistent expansion ratio, strong bonding to various surfaces like wood, metal, and concrete, and resistance to moisture and temperature fluctuations. These foams cure quickly, minimizing mess and downtime, while providing excellent thermal and acoustic insulation. Whether you're air-sealing attics, securing window frames, or filling cracks in foundations, RedDevil ensures a professional finish every time.

As part of the larger Polyurethane Foams category, RedDevil products shine for their user-friendly application via standard spray cans, no special equipment needed. If you're exploring broader options, check out related selections in Raw Materials for complementary supplies.

Key Features to Consider When Shopping

When selecting from RedDevil Polyurethane Foams, focus on these critical attributes to match your project needs:

  • Expansion Capability: Foams expand to fill irregular spaces, but controlled expansion prevents overfill and structural issues.
  • Adhesion and Flexibility: Look for paints that bond well and remain flexible post-cure to handle building movement.
  • Cure Time and Temperature Range: Fast-curing formulas work in a wide range of conditions, from cold basements to hot attics.
  • Can Size and Yield: 12 oz cans provide ample coverage for most jobs without waste.
  • Color and Finish: Off-white tint blends discreetly under paint or trim.

RedDevil excels in these areas, offering foams that are low-odor, easy to trim, and compatible with common building materials.

Comparing RedDevil Models: 0913 vs. 0909

RedDevil's lineup in this category features two targeted solutions to help you choose precisely. The 0913 Spray Foam & Fill is optimized for small gaps and cracks, such as those around pipes, electrical outlets, or drafty windows. Its precise application nozzle allows for targeted dispensing, expanding just enough to seal without excessive buildup—ideal for interior touch-ups where space is tight.

In contrast, the 0909 Spray Foam tackles larger gaps and cracks, like those in rim joists, sill plates, or exterior sheathing. It delivers greater expansion volume, filling voids up to several inches deep while maintaining structural integrity. Both share the same off-white color and 12 oz size for consistency, but the 0909's higher yield makes it better for bigger projects.

Choose the 0913 if your work involves fine detailing; opt for the 0909 when volume is key. For alternatives, consider brands like Loctite Polyurethane Foams or Smooth-On Polyurethane Foams, which offer varying densities for specialized needs.

Common Use Cases for RedDevil Foams

These foams are versatile across residential, commercial, and industrial applications:

  • Home Insulation: Seal air leaks to boost energy efficiency and comfort.
  • Construction and Remodeling: Secure doors, windows, and HVAC penetrations.
  • Soundproofing: Dampen noise in walls, floors, and ceilings.
  • Pest and Moisture Barrier: Block entry points for insects and water infiltration.

Backed by RedDevil's commitment to quality, these products fit seamlessly into workflows within Industrial & Scientific projects. Users appreciate their paintability, allowing for seamless integration into finished spaces.
