What Is Knocked Down (KD) Ductwork?
Also known as unassembled or sectioned ductwork, knockdown ductwork consists of two longitudinal seams in need of joining. Since this type of ductwork is in an “L” shape, it can be stacked for easy transportation. Once it arrives at the jobsite, it can be seamed together there.
In today’s blog post, we are going to discuss everything you need to know about knocked down ductwork. Read on to learn more.
At MetalMarketz, we believe in high-quality metal works that will last a lifetime. If you’re in need of knocked down ductwork in NYC, reach out to our team for a quote today.
The Basics: Knocked Down Ductwork 101
Knocked down ductwork is essentially a bunch of L-shaped, pre-designed and manufactured sections ready for assembly on-site. These premade sections are easy to transport and also a convenient way to save money on transportation expenses. Once the pieces arrive at the jobsite, the HVAC team can assemble them on-site.
Types of Knocked Down Ductwork
At MetalMarketz, we offer our knocked down ductwork in two types: straight joints, and straight ductwork with a half-inch liner. The ductwork with the liner offers noise reduction and can help insulate the ducts, possibly reducing energy bills.
Is Flexible Ductwork Same as Knocked Down Ductwork?
One of the most common questions people ask is whether flexible ductwork is the same as knock down ductwork. Flexible ductwork is essentially used in rigid or tight spaces. These ducts can easily mold or bend around awkward spaces to get the job done. On the other hand, knocked down ductwork is a series of stackable, easily transportable L-shaped sections that can be assembled on site. Therefore, its inability to bend around rigid spaces does not fit the criteria of flexible ductwork.
How Long Does It Take To Install?
Knocked down ductwork is preferred by some contractors because it's easily transported. However, since it comes in convenient L-shaped sections, it does need to be assembled on-site. This assembly will extend the time of the project, and require more labor. Where you save money and time on transportation, you will have to consider the extra assembly time and expenses. Ultimately, the time that knock down ductwork, or any ductwork for that matter takes to install is dependent on the size of the job and how many crew members are working on said job.
Knocked down ductwork is perhaps one of the most convenient and easily transportable types of ductwork available. Perhaps the most defining feature of this ductwork is the stackable L-shaped sections that can be transported in bulk from the manufacturer to the jobsite. At MetalMarketz, we are always striving to build some of the most unique and functional types of ductwork available in NYC.
