What is the Lifespan of Duct Board?
With proper maintenance and cleaning procedures, a duct board could easily last for 10-15 years. However, the lifespan can significantly vary depending on usage conditions or external factors such as environmental humidity and temperature.
Pros of Duct Board
Easy Installation
One of the major pros of duct board is that it is very easy to install. Unlike other duct materials such as sheet metal, duct board can be easily cut to size with a special knife and no special tools are required. They come in lightweight panels hat are labelled with measurements for easy cutting and installation, hence, a good fit for DIY projects.
Noise Reduction
Duct board, due to its insulating material (often a combination of fiberglass and foil), absorbs sound rather than transmitting it. When air blows through metal ducts they can create a significant amount of noise, duct board reduces such nuisance.
Insulation
Duct board is an excellent insulator. Its insulating properties mean that it is better at keeping heat in (or out) than metal ductwork. This can lead to higher energy efficiency for your HVAC system and possibly lower energy bills.
Condensation and Heat Loss Control
Duct boards have a built-in vapor barrier that helps prevent condensation that is commonly associated with metal ductwork. This prevents damage to surrounding areas from condensation dripping. It also prevents heat from escaping the ductwork, helping your heating system run more efficiently.
Cons of Duct Board
Durability
While duct board is easier to install, it is not as durable as its metal counterparts. It can be easily damaged by sharp objects or heavy items pressing against it. Moreover, if not properly sealed, moisture can penetrate the board and weaken it over time.
Health Concerns
Fiberglass, one of the primary components of duct board, can be a health hazard if particles are released into the air and breathed in. This can happen if the board is damaged or improperly installed.
Limited Shape and Sizes
Duct board comes in standard sizes and shapes; customization options can be limited. This can create issues in older homes or in tight spaces where customized ductwork might be necessary.
Cleaning Difficulties
Cleaning duct boards can be challenging. Unlike metal ducts that can be scrubbed and cleaned properly, the fibrous material of the duct board can trap dust and other particles. Over time, this build-up can lead to a deterioration of the air quality in the home.
Fire Concerns
While fire rated duct board is available, standard duct board can pose a fire hazard if exposed to high temperatures. This may necessitate additional precautions in installation.
