DH Roadworks Ltd lays 1-5 ducts of sizes between 2 inches to 5 inches in Footways, Verges, Modular services, and carriageways. We also rod and rope the ducts using traditional methods.

What is Duct Laying?

Duct laying refers to installing ductwork, a system of channels used for heating, ventilation, and air conditioning (HVAC) systems. Ductwork is typically made of sheet metal, fibre-glass, or flexible materials, and is used to distribute conditioned air throughout a building.

The process of duct laying involves several steps, including:

1. Planning: The first step in duct laying is to determine the layout of the ductwork system, measure the space and choose the best path for the ducts to run, and decide on the ducts’ size and shape.
2. Fabrication: Once the layout is determined, the ductwork is fabricated off-site in a factory or a sheet metal shop. An engineer will transport the ducts to the job site for installation.
3. Installation: An engineer will install the ducts in the building, typically by hanging them from the ceiling or attaching them to the walls. An engineer will connect the ducts to the HVAC system, adding any necessary insulation to prevent heat loss or gain.
4. Testing: After the ducts are installed, an engineer will test to ensure that they are properly sealed and that there are no leaks or other issues that could affect the performance of the HVAC system.

Proper duct laying is essential for the efficient operation of an HVAC system. Poorly installed ducts can lead to air leaks, which can cause the system to work harder than necessary and lead to higher energy costs. Additionally, appropriately sized ducts can lead to better airflow and reduced comfort in the building. Therefore, working with qualified professionals must ensure duct laying is correct.
