Physical and Thermal Properties

Ceramic duct wraps are engineered to endure extremely high temperatures while delivering effective insulation and fire protection. These wraps are constructed from inorganic, non-combustible ceramic fibres such as alumina, silica, or alkaline-earth silicate wool, capable of withstanding temperatures of 2000°F or more.
Manufactured as flexible blankets, ceramic duct wraps easily conform around ducts, ensuring a snug fit with minimal gaps. Their low thermal conductivity significantly reduces heat transfer, making them ideal for high-temperature applications. Typically, they're around 1.5 to 2 inches thick with a density of approximately 6 pounds per cubic foot, achieving a balance between insulation efficiency and ease of installation.
The fire-resistant characteristics of these wraps enable them to meet stringent safety standards, including fire ratings of up to two hours and compliance with fire regulations, thereby safeguarding both property and personnel.

Best Practices for Installation

Proper installation of ceramic duct wraps is vital to ensure their effectiveness and safety. It's important to follow mechanical attachment methods with care.
Utilise steel banding that's at least half an inch wide, spaced no more than ten and a half inches apart around the duct, and position the bands one and a half inches from the insulation edges. For larger ducts, steel pins (minimum twelve gauge and three to five inches long) should be arranged in rows, spaced a maximum of ten and a half inches apart and five inches from the duct edges.
Ensure that there's an overlap of at least three inches between the blankets, and seal all cut edges with aluminium foil tape. Initiating the wrap at the correct edge, attaching it securely to concrete or masonry, and ensuring that all sections are well fastened helps to prevent gaps and maintains the integrity of the system.
Regular inspections are essential for ensuring long-lasting, safe insulation. By adhering to these best practices, you can significantly enhance the performance and durability of your ceramic duct wraps.
