Ductwork: Its Various Kinds And Applications

Ducts are used for air conditioning, heating and ventilation to give and remove air. These much needed airflows allow supply, return and exhaustion of air. Most commonly they are created for the purpose of ventilation. Hence, they guarantee acceptable indoor air quality with thermal comfort. A duct system is called ductwork.

Pre insulated duct panels have benefits of their own such as they are much lighter in weight, saves space and time as they can be installed in a single go and pre insulated panel suppliers can be easily modified on site as and this feature could come in use in case the design of your building meets unforeseen changes. If you are looking for excellent pre insulated panel suppliers in Singapore, you can go through Yitac’s services. They deliver pre insulated ductwork with competitive prices and quality innovative engineering methods.

Yitac also provides wide range of options for your air conditioning functionality like ABS grilles like single and double deflection grille, frameless bar grille among other services.

Now, moving on, there are different types of ductwork fabrication and they can be made of variety of materials


Polyurethane And Phenolic Insulation Panels

Traditionally, air duct work is usually made of sheet metal that is is installed first and then strung with insulation secondarily. Ductwork that are manufactured from rigid insulation panels doesn’t need any further insulation as it is installed it a single fix. Common features of pre insulated aluminium ductwork are lightweight and installation speed.

Fibreglass Duct Board

They are pre insulated non-metallic duct system. The fibre glass offers built in thermal insulation and its interior soak up the sound, that minimizes equipment noise  and enables quiet operation of the heating, ventilation and air conditioning (HVAC system). It boosts energy efficiency and saves money by reducing heat gain or loss. It offers better moisture resistance than other duct boards.

Flexible Ducting

Also known as flex, come with variety of configurations, but in regard to HVAC application, they are particularly flexible wrapped over a metal wire to form a round shaped duct. Various  thermal insulation techniques are used such as glass wool, polyester fibre are used. Flexible duct work is quite convenient for attaching supply air outlets to rigid ductwork. However, loss of pressure is higher than most other duct types.

Fabric Ductwork
Also known as air socks, textile ducts or duct socks, are crafted for even distribution and blending of air throughout the entire length in a given space. It is usually created of specially designed porous polyester, these air socks act as a conventional system with much more diffusers. It isn’t designed to serve as a channel for conditioned air.

Fabric ducts weigh less, can be easily installed and puts less stress generally on the building’s structure. They come with different fabric, ie. porous or non porous. To determine which fabric is appropriate, it needs to be considered if the particular application would need an insulated metal duct. Material that eradicates moisture  will be a healthier choice for the occupants.

To know which type of ductwork is best for you, you will require ductwork installation experts to examine your home or office to ascertain which type will fit appropriately with the space in your house. The kind of HVAC system that you plan to install also affects this decision.
