Duct or ducting is pathway (passage or conduit) that allow the carriage and delivery of air ventilation, air conditioning, heating or cooling system (also known as HVAC). Ducting helps very much in air supply, air suction. It acts as a stabilizer of temperature and air quality upgrader, providing comfort to industrial, commercial and residential user. A complete ductwork (or duct system) involves planning from the existing layout, resizing it, optimizing the existing space with saved resources as well as controlled pressures losses.
Ducting fabricator in Malaysia can generally make duct system formed by different materials such as galvanized steel, fabric ducting, flexible ducting, aluminium, polyurethane and phenolic insulation panels (pre-insulated air ducts), waterproofed duct as well as fiberglass duct board (preinsulated non-metallic ductwork). Every kind of ducting material has different functionality, hence, ducting system should be designed and custom made in order to fit the user’s requirement.
Zinc coated based galvanized steel ducting allows no painting cost and rust-free, this is one of the most standard classic material widely offered by ducting supplier in Malaysia. In order to have insulation feature, this kind of metal duct often equipped with fibreglass lining or alternatively, wrapped by fiberglass blankets externally. One to two inches thickness of fibreglass forming the inner perforated liner when double walled ducting is required. It is usually fabricated in rectangular shape by ducting specialist in Malaysia, four inches joints will be coupled with the duct system just to ensure convenience in handling. There is also round shaped ducting system in the industry where continuous spiral forming machine is the one that manufacture it, the length and diameter are fabricate-able with today’s machinery so it is able fit-to-need.
Fabric-based ducting has more to do with air distribution rather than acting as an air-conditioning conduit, fabric duct can make the distribution of air to be more even due to its base material, polyesther. Ducting supplier Malaysia does also use this material to fabricate orifices and vents too, it is normally available in wide variety of colours. Besides these, fabric ducts can also be porous, non-porous (not air-permeable), silk screening options or other kind of decoration forms. Ducting with porousity has lower maintenance cost since it airborne contaminants and dusts are repelled.
As per market awareness of going green and to be environmentally friendly, ducting fabricator Malaysia does also use fabric that has over 50% recycled material which allows it parks under the green building material category. Fabric-based ducting is fire retardant, while it has lightweight feature which will allocate lesser stress load to the overall structure of building; installation also become easier due to its light in weight.
Flexible plastic is the key component to manufacture flexible ducts, it can be made by metal wire coil in which to form the tube shape. Ducting specialist Malaysia does provide heat and sound insulation through adding in glass wool and polyester fibre, the outer layer protecting the insulation also might be formed by polyethylene. This kind of ducting allows air outlet to be attached onto the ductwork that is rigid, normally by metal band claps or zip ties which has elongated. Generally, its length will be shorter than 15 feet in order to keep loss in pressure minimized, same applies to the turn and elbow.
This option is also one of the preferred materials by construction and industrial player in the market because of its customizability, convenient to install and lighter in weight. Ducting supplier in Malaysia can fabricate this type of aluminium ducting on-site or off-site at facto
