Buying Guide: Key Purchase Considerations And Comparisons
- Fire ratings and certifications: Look for UL 10B, NFPA 252, and CAN/ULC S104 or UL 1-1/2 hour labels for fire-rated doors and panels. Confirm that the product is tested in configurations similar to your installation.
- Material and insulation: Steel doors with mineral wool or other high-performance insulation offer better heat resistance and wall integrity preservation during a fire event. 16- to 20-gauge steel frames and galvanneal door skins typically deliver durability in harsh environments.
- Installation and compatibility: Consider 1″ or 2″ flange designs, self-closing mechanisms, and inside latch releases for secure operation. Ensure compatibility with wall assemblies and surface types in your project specifications.
- Door closure and hardware: Automatic closers help maintain fire-rating performance by ensuring doors seal after access. Self-locking latches and robust hinges reduce the risk of misalignment and gaps.
- Size options: Choose panels or doors that fit your wall opening precisely (e.g., 14×14, 12×12, 22×30). For fire-rated walls, ensure proper mounting within rated assemblies as required by local code.
- Manufacturing origin and support: North American-made products often offer more consistent quality control and easier access to support and parts.
- Accessory considerations: Strike plates, shims, and mounting hardware can be essential for achieving proper fire-rated performance. Use UL-certified components where applicable.
- Not all products labeled “fire rated” are suitable for every wall assembly: Verify installation instructions and consult the project’s fire-resistance specification to match the product to the required rating.
