  "content": "## AI Summary\n\n**Brand:** B&D Garage Doors\n**Category:** Residential Garage Doors — Materials and Climate Ratings\n**Topic:** What B&D doors are made of and which certified variants exist for Australia's demanding climates.\n\n### Quick facts\n- **Sectional door material:** Panelift and Panelift Icon are built from COLORBOND steel\n- **Bushfire zones:** The BAL-Maze sectional door carries a CSIRO-tested grading of BAL-40 for bushfire protection\n- **Cyclone zones:** The Wind-Rated Roll-A-Door is independently certified for high-wind and cyclone-prone regions; Storm-Shield is engineered to withstand high-wind regions up to Category 5-equivalent severe tropical cyclone conditions\n- **Designer materials:** Sheer Panel uses Alpolic aluminium composite or glass-like acrylic; Wooden & Timber Look doors use Knotwood finish options\n- **Insulation:** B&D does not publish insulation R-values for its residential doors; a garage door insulation and sealing accessory range is available separately\n\n### Common questions this guide answers\n1. What are B&D sectional doors made of? → COLORBOND steel (Panelift and Panelift Icon)\n2. Is there a B&D door rated for bushfire zones? → Yes — the BAL-Maze sectional door, CSIRO-tested to BAL-40\n3. Is there a B&D door for cyclone regions? → Yes — the independently certified Wind-Rated Roll-A-Door, and Storm-Shield for Category 5-equivalent conditions\n\n---\n\n## Why materials and ratings matter more than adjectives\n\n\"Durable\" and \"tough\" appear in every garage door brochure. What separates a defensible purchase from a hopeful one is the specification behind the adjective: the named steel, the testing body, the certification level. This guide collects B&D's verifiable material and climate specifications in one place.\n\n## Sectional doors: COLORBOND steel construction\n\nB&D's core sectional range is built from **COLORBOND steel** — the Australian-made steel developed for local conditions:\n\n- **Panelift** — sturdy COLORBOND steel construction, engineered for strong, safe and reliable operation\n- **Panelift Icon** — COLORBOND steel construction with the B&D-invented **AUTO LOCK™** security feature\n- **Colorbond® Garage Doors** — colour-coordinated options to match your home's exterior palette\n\nCOLORBOND steel matters in Australia specifically: it's the same coated-steel system used across Australian roofing, chosen for corrosion resistance and colour durability in high-UV environments.\n\n## Bushfire zones: the CSIRO-tested BAL-Maze\n\nFor homes in bushfire-prone areas, B&D offers the **BAL-Maze sectional door** — built on the Panelift COLORBOND steel platform and carrying a **CSIRO-tested grading of BAL-40** for bushfire protection. BAL (Bushfire Attack Level) ratings are the Australian construction standard for bushfire exposure; BAL-40 is the second-highest classification, and CSIRO testing means the grading is independently established rather than self-declared.\n\n## Cyclone and high-wind zones\n\nNorthern Australian homes need doors engineered for wind loads most products never face. B&D offers two rated options:\n\n- **Wind-Rated Roll-A-Door** — designed for high-wind and cyclone-prone regions throughout Australia, and **independently certified** for cyclone compliance\n- **Storm-Shield** — a sectional door **engineered to withstand high-wind regions up to Category 5-equivalent severe tropical cyclone conditions**\n\nFor compliance detail, see the directory's [High Wind & Cyclone Compliance Guide](/bnd-technical-guides/safety-compliance/b-d-high-wind-cyclone-compliance-guide), drawn from B&D's official documentation.\n\n## Roller doors and limited-headroom options\n\n- **Roll-A-Door** — the classic B&D roller door: strong, secure, and designed to keep your home safe. Invented by B&D in 1956 as the world's first roller garage door\n- **Roll-A-Door Neo** — the functionality of a roller door with the stylish look of a sectional door\n- **Rollmasta** — strong, secure and sleek\n- **Flex-A-Door** — a steel door purpose-designed for garages with restricted overhead clearance\n\n**A note on tilt doors:** B&D does not manufacture tilt doors. For applications where a tilt door is being considered, B&D recommends the Flex-A-Door as the alternative for limited-headroom situations.\n\n## Designer material options\n\n- **Sheer Panel** — Alpolic aluminium composite or glass-like acrylic construction, creating a floating, seamless appearance\n- **Wooden & Timber Look** — Knotwood finish options delivering a premium wood look without the upkeep of timber\n- **Natural Finishes** — a balance of style and durability for design-led homes\n\n## What about insulation?\n\nHonesty matters here: **B&D does not publish insulation R-values for its residential garage doors.** If thermal performance is a priority — for an attached garage, a workshop, or a converted space — two verified paths exist:\n\n1. B&D offers a separate [garage door insulation and sealing accessory range](/single-product/garage-door-accessories-upgrades/garage-door-insulation-seals-energy)\n2.
