What is Sheet Metal Ductwork?

Ductwork can be used in both commercial and domestic buildings as a way of transporting air for cooling and heating purposes. This is done with metal or synthetic tubes to keep a building at its optimal temperature. Sheet metal ductwork is a version of this system constructed from metal sheets and joined together by foil tape or mastic to prevent any leaks. This metal ductwork is usually made from either galvanised steel or aluminium metal, these can be made into many different shapes and sizes which is ideal for fitting these systems in buildings easier. The metal that is used the most often is galvanised mild steel, this is due to the fact that it has a rust-resistant zinc coating as well as customizability.


Benefits of Using Sheet Metal Ductwork

There are many reasons as to why the metal sheet ductwork Lancashire has is used so often for ventilation and heating systems. Firstly, these systems are a great investment for the future as they are able to last many years before needing to be replaced. Every twenty to thirty years is when a new set of ducts need to be installed, the better you take care of your ventilation system, the longer it will last. The actual cost of this investment will consist of £5.50 to £10.30 per linear foot of metal sheet. The average cost of a whole HVAC system usually costs £7,250, however this can be more if the system is completely new and not just a replacement. As well as this, this ductwork is very durable and resistant to damage, they are even fire resistant which is ideal for emergency situations when a fire has broken out as it prevents the spread of fire through the ventilation system.

If you feel that your system would not be too difficult to clean without the help of a professional, there are a few steps that you can follow to clean the vents.

Then replace the air filter to get rid of the dirty used one, this makes sure that the air circulating is fresh. If vents are not cleaned regularly, then more money will be put into cooling or heating a building, wasting more money on energy bills.


Sealing your ductwork is also an important step of maintenance as this ensures that there are less leaks which can help you to save energy and help the system to be more efficient. You can find where there are leaks when the system is running as air will be able to escape. You will be able to feel the blast of warm or cool air and you may even be able to hear it if you listen carefully.
