Introducing our semi-Rigid Aluminum Duct

a high-quality single-layer aluminum duct designed for a range of demanding applications. Semi-Rigid Aluminum Duct combines the strength and durability of rigid ductwork with the adaptability and ease of installation of flexible ducts, making it an exceptional choice for various industrial, commercial, and residential needs.

The duct, crafted from aluminum, offers a level of insulation, safeguarding against external objects, weather elements, moisture, water, high heat, bacterial intrusion, acids, etc. This protection prevents the penetration of these external factors. The aluminum’s uniform and seamless structure ensures no water infiltration and air leakage, thereby preventing energy loss, boosting the duct’s efficiency, and extending its lifespan. Moreover, the duct’s accordion-like design provides high resistance to combustion and fire spread.

The duct’s flexibility, indicated by its accordion-like appearance, allows easy expansion and contraction, enabling installation in tight spaces and simplifying the installation process due to its lightweight aluminum construction.

For residential applications, particularly in kitchens, our 6-inch Semi-Rigid Aluminum Duct is ideal for range hoods, providing efficient venting of smoke, odors, and moisture. This size is specifically designed to meet the needs of home cooking exhaust systems, ensuring a clean and safe kitchen environment.

Installation of this accordion duct is straightforward, requiring only a skilled installer to ensure it is set up correctly to avoid potential issues arising from improper installation. Despite the potential for various challenges, the duct remains cost-effective and readily available, offering significant savings in time and costs.

The duct is available in various sizes and lengths to suit different applications. While its primary use is as a kitchen hood duct in residential spaces, it is also suitable for larger settings like industrial kitchens and factories, provided the air pressure is not too high. For these larger applications, the biggest duct sizes are utilized to ensure efficiency and durability, even in the most demanding environments, highlighting the versatility of our HVAC rigid duct offerings.
