Access Door, 2 Hr Wall/1 Hr Ceiling, UV/Salt Rated, Insulated Steel, Flush Mount

The Linhdor Nova 8000 is a high-performance, fire-rated access door engineered for both ceiling and wall installations in demanding environments. Constructed from insulated, heavy-duty steel, this flush-mount panel is designed to deliver strength, reliability, and code-compliant access in commercial, industrial, and institutional settings.The Nova 8000 is now certified with a 2-hour fire rating for wall installations and a 1-hour fire rating for ceiling applications, meeting stringent fire safety requirements across a variety of building types. It features a knurled key knob for easy manual operation and an interior-release latch for added safety, making it ideal for access to electrical, mechanical, or plumbing systems behind fire-rated assemblies.This model is also UV rated and has passed ASTM G154-23 Fluorescent UV and ASTM G155-21 Xenon Arc accelerated exposure tests. During a 48-hour test cycle, the panel showed no visible change in finish, color, or gloss, proving its durability in sun-intensive and outdoor environments. Testing was independently performed by Element Materials Technology to verify real-world resistance to sunlight degradation.In addition, the Nova 8000 has achieved Salt Spray Certification through ASTM B117-19 48-hour testing, confirming exceptional corrosion resistance in high-humidity and moisture-prone conditions.

• Dual Fire Rating: Certified for 2-hour fire rating in wall installations and 1-hour in ceilings, meeting building code requirements for rated assemblies in commercial, institutional, and multi-family applications.
• UV Resistance – ASTM G154 & G155 Certified: Engineered for long-term outdoor durability. Passed 48-hour accelerated UV exposure using Fluorescent UV and Xenon Arc methods with no visible change in finish, color, or gloss. Ideal for sun-intensive, high-UV environments. Independently tested by Element Materials Technology
• Salt Spray Certified – ASTM B117 Tested: Designed for coastal and high-moisture areas, the panel passed 48-hour salt spray testing with excellent corrosion resistance. Minimal red rust appeared only on cut edges; the core finish remained intact under harsh exposure.
• Insulated Steel Construction with Mineral Wool Core: Built for performance in fire-rated assemblies, the steel panel is filled with fire-resistant mineral wool insulation, providing both thermal protection and added sound resistance.
• Knurled Key Knob + Interior Release Latch: Combines ease of use and safety. The knurled key knob allows secure, tool-free access while the interior latch supports safe use in ceiling applications and meets fire-rated hardware compliance.
• Flush Mount Frame Design: Installs seamlessly into drywall walls or ceilings for a clean, low-profile appearance. No visible latches or hinges interrupt the finished surface.
• Paintable Baked Enamel Finish: Factory-applied white baked enamel finish is durable, corrosion-resistant, and field-paintable to match surrounding finishes.
• 2025 Lab Tested: Fire rating, UV durability, and salt spray resistance all verified by Element Materials Technology, a trusted third-party laboratory
