PU Foam

What is PU Foam Insulation?

Polyurethane (PU) foam is a high-expansion, airtight sealant that hardens after application. It’s widely used for:

✔ Filling gaps in walls, roofs, and pipes
✔ Soundproofing and thermal insulation
✔ Securing windows, doors, and HVAC systems
✔ Waterproofing against leaks and moisture

Our 650ml cans (12pcs per pack) provide optimal coverage for both small repairs and large-scale projects.


Top 5 Benefits of PU Foam Insulation

  1. Superior Adhesion – Bonds strongly to wood, concrete, metal, and plastic.
  2. Thermal & Acoustic Insulation – Reduces energy costs and noise pollution.
  3. Moisture-Resistant – Prevents mold and water damage.
  4. Quick Expansion & Curing – Saves time on construction projects.
  5. Cost-Effective Pack (12pcs) – Ideal for bulk buyers and contractors.

How to Use PU Foam Insulation Like a Pro

Step 1: Preparation

  • Wear gloves and goggles (foam expands rapidly).
  • Shake the can well before use.

Step 2: Application

  • Cut nozzle at a 45° angle for precision.
  • Fill gaps 1/3 full (foam expands 2-3x).

Step 3: Curing & Finishing

  • Let it dry for 4-6 hours.
  • Trim excess foam with a knife for a clean finish.

5 Common Mistakes to Avoid with PU Foam

❌ Overfilling gaps (leads to messy expansion).
❌ Applying in cold temperatures (reduces effectiveness).
❌ Ignoring safety gear (foam is sticky and hard to remove).
❌ Not storing cans upright (causes leakage).
❌ Using expired foam (check manufacturing date).
