KOROK® External Wall Systems provide a comprehensive solution for fire-rated, acoustic-rated, and weatherproof protection in external applications, including boundary walls. These all-in-one systems are designed for New Zealand’s unique environmental conditions, offering superior fire resistance, sound insulation, and weatherproofing with a fast and cost-effective installation process.
Key Benefits of KOROK® External Wall Systems:
- Lightweight & Cost-Effective: Ideal for fire-rated boundary walls in commercial buildings, KOROK® systems reduce material costs and installation time.
- No Engineered Slab Required: Save on construction costs by avoiding the need for specially engineered slabs, leading to significant cost savings and programme advantages.
- Easy Installation: With no need for cranes or heavy lifting equipment, a small team can manage the installation process, streamlining construction.
- Weather-Tight & Durable: Specifically designed for New Zealand’s high-wind zones and external conditions, KOROK® systems don’t require additional cladding to ensure long-lasting durability.
- Fire & Acoustic Efficiency: Enhance fire protection and soundproofing without the need for extra internal framing, making these systems both practical and efficient.
