Choosing the Right Spray Foam & Polyurea Coatings for Your Job

When it comes to insulation, waterproofing, and fire protection, the products you choose matter. At T4 Supply, we offer industry-trusted spray foam and polyurea coatings that deliver the performance your projects demand. Whether you're insulating a home, sealing a roof, or protecting structural steel, understanding your material options can make all the difference in long-term results.

🔍 Closed-Cell vs. Open-Cell Spray Foam: What’s the Difference?

Closed-Cell Spray Foam

• Dense & rigid, creating a strong vapor barrier

• Ideal for roofs, basements, and commercial buildings

• Higher R-value per inch (more thermal resistance)

• Adds structural strength

Open-Cell Spray Foam

• Soft & flexible, with excellent soundproofing

• Best for interior walls and attics

• Lower cost and lighter weight

• More breathable and forgiving in moisture-prone areas

Use Case Tip:
For extreme climates or high-moisture areas, go closed-cell. For interior sound control or tighter budgets, open-cell may be the better fit.

💧 Why Choose Polyurea?

Polyurea is a fast-curing, ultra-durable coating perfect for waterproofing and protective applications. It’s widely used in:

• Foundation sealing

• Roof and deck coatings

• Truck bed liners

• Industrial flooring

With incredible resistance to chemicals, abrasion, and moisture, polyurea offers serious longevity—even in harsh environments. At T4 Supply, we carry trusted formulations that contractors rely on for consistent coverage and reliable performance.

🔥 Intumescent Fireproofing: Safety First

Looking for fire protection that meets code requirements? Intumescent coatings expand when exposed to heat, forming a char layer that slows the spread of fire. They're ideal for:

• Structural steel protection

• Spray foam applications requiring fire rating

• Interior commercial spaces

We carry UL-rated intumescent products that meet most code requirements and work seamlessly with our spray foam systems.
