Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Insulation & Gap Sealing: Expands rapidly to fill gaps and insulate windows, doors, and construction joints with a closed-cell structure, providing thermal and acoustic insulation.
  • Anti-Shrinkage Formula: Maintains structural integrity over time, ensuring long-lasting seals without contraction, even in varying environmental conditions.

Key features

  • 1. Advanced Material Technology

    • With a closed-cell polyurethane structure, achieve superior thermal insulation and moisture resistance compared to open-cell alternatives*. The foam’s durable material ensures long-lasting performance in harsh environments, ideal for construction and insulation projects.

  • 2. Simplified Interactive Design

    • With a single-component formula, eliminate the need for mixing, making it easier to use than dual-component foams*. The intuitive spray application streamlines DIY and professional installations, reducing setup time and effort.

  • 3. High-Performance Foaming Capacity

    • With a rapid expansion ratio of up to 30 times its liquid volume, fill gaps quickly and efficiently—20% faster than standard foams*. This ensures seamless sealing for windows, doors, and other construction joints, even in tight spaces.

  • 4. Anti-Shrinkage Durability

    • With anti-shrinkage technology, maintain a stable seal over time, reducing the need for reapplication compared to traditional foams*. Perfect for long-term use in home and commercial settings, ensuring consistent insulation and weatherproofing.

  • 5. Eco-Friendly Certification Compliance

    • With EC 1907/2006 (REACH) certification, ensure compliance with EU environmental and safety standards, unlike uncertified alternatives*. This makes it a trusted choice for eco-conscious construction and insulation projects.

Supplier's note

  1. Technical Breakthroughs:

    • High Foaming Rate: 20% faster expansion than traditional foams reduces labor time by 25%.
    • Anti-Shrinkage Formula: Maintains structural integrity over 10 years, outperforming industry-standard 5-year guarantees.
    • Closed-Cell Structure: Achieves R-4.0 insulation in the Pro Model, ideal for extreme climate regions.

  2. Optimal Version Selection:

    • Base Model: Suitable for DIYers and small-scale repairs (e.g., sealing door frames).
    • Advanced Model: Recommended for contractors needing medium-duty insulation (e.g., home renovations).
    • Pro Model: Best for industrial applications (e.g., automotive manufacturing or commercial construction) where high expansion and durability are critical.

With the Pro Model’s R-4.0 insulation, you can reduce energy costs by 30% in HVAC systems. Pair its 40x expansion ratio with closed-cell technology to create airtight seals in steel frames, ensuring long-term performance.
