On the other hand, a hard duct is an expensive upfront expense for a commercial building, but it saves money – regardless of the outside environment – by ensuring high indoor air quality and controlling indoor temperature. Since hard ducts are made of galvanized steel or aluminum, the cost of transporting, creating, and installing them is higher. Price – Flex ducts are significantly cheaper than hard ducts.For this reason, they are suitable for constructing an entire HVAC system. Owing to the design of steel, hard ducts are stronger. This is because they’re more versatile and functional. Flexibility – For current trunk-and-branch heating and cooling systems, flex ducts are safer.The Difference Between Flex And Hard Duct The reason is that hard ducts require space to optimize performance and energy efficiency. Hard duct requires measurements, computerized design, as well as careful ductwork installation.īefore installing them, professionals consider the existing parts of the commercial building’s cooling and heating system, including the air conditioner, furnace, heat pump, and others.Īside from that, professionals also consider the width-to-height ratio in a commercial building. Yet, you don’t have to worry because the surface of such ducting material is smooth and generally easy to clean. Inside this ductwork is where dust, as well as debris and other particles, are trapped. It is made of aluminum or galvanized steel, featuring a thick, solid wall that makes it incredibly durable. Hard Duct: ExplainedĪlso known as metal ducts, hard duct provides a more permanent solution to commercial HVAC system due to its rigidness. The reason is that, for any heavy-duty hose, each provides versatility. Yet, for air handling environments, silicon and PVC offer the highest quality. Highest Quality For Air Handling Environmentsĭuring extreme weather, silicon cannot handle inner damage. In fact, most water supply lines contain rubber and polyurethane for extra durability and flexibility. This type of flex duct provides the best abrasive resistance. If you are looking for a flexible duct that is not easy to wear away by friction or rubbing, choose a flex duct made of polyurethane or rubber. If you are planning to buy ductwork for such a building, consider the said materials. This is because long-lasting efficiency ensures an intrinsic tolerance to heat and cooling. In harsh climates, plastic, PVC, stainless steel, and silicone are best suitable for industrial buildings. To help you determine if the flexible duct is best suitable for your ducting needs, here is a list that you should note about: 1. It is convenient, especially for mounting supply air outlets to hard ductwork, and is usually connected with metal band clamps or long zip ties. This ductwork connects the cooling and heating system ductwork to the air distribution, which includes registers and grills installed in the ceiling or walls of commercial buildings. To determine the reason why hard duct is most often than not considered as a better type of AC duct, here is a clear comparison of the two: What Is A Flexible Duct?įlexible or flex duct is characterized as a long ductwork tube with better flexibility when fitting into awkward spaces than the hard duct.Īmong the most common types of flexible ductwork, materials include rubber, stainless steel, PVC, polyurethane, silicone, and neoprene-dipped polyester fabric. Let’s proceed with the discussion, shall we? Flex Duct vs. To discuss more of why hard duct is mostly better than flex duct, below is a clear comparison between the characteristics of the two.Īlso, check out which one is suitable for your needs in the latter part of the article. Since it is made of sheet metal, it provides a more lasting solution to a commercial HVAC system, especially with proper and regular maintenance. Hard ducts are most often considered the most effective and safest type of ductwork. Since the duct plays an important role in distributing air inside your home, knowing which type of duct is better will allow you to enjoy huge savings over time. Using only one machine, Ducted Air Conditioners will cool any space in your home or workplace. The most powerful ventilation system for residences and industries on the market today is ducted air conditioning.
