Can You Cut Plastic Ducting?

Can You Cut Plastic Ducting?

In order to prevent mould, fresh air should always be introduced into your dwelling on a daily basis, as it helps to regulate temperature and reduce condensation. Introducing fresh air can be as simple as having a ventilation routine, or installing extractors or PIV systems.

For those taking this route and choosing to install themselves, we will answer the question ‘Can you cut plastic ducting?’

We at I-Sells are here to provide the answers you need whilst also supplying you with all the information you need in order to combat mould and have a well-ventilated home.

What is plastic ducting used for?

Plastic ducting is used in order to create an isolated airflow for extracted air to travel through, the airflow is facilitated by the use of an extractor fan or PIV system.

These systems aid in creating a home with fresh air and helps to regulate the temperature in order to prevent the cultivation of mould and dampness.

Mould, otherwise known as damp, is a fungus that grows on wet surfaces. Mould comes in a variety of colours: Black, Green, Brown, Grey and White. It can be difficult to identify mould by colour as it can occur in many shades.

Mould reproduces from tiny spores. The spores float through the air and deposit on the surfaces. Under adequate temperature, moisture, and nutrient conditions, the spores can form new mould colonies.

condensation is not the only cause of mould, it can occur from leaks in the structure of a building too.

Mould can severely affect your immune and respiratory system, as the spores are easily breathable and not obvious to see through the human eye.

If you have found mould in your home, you need to assess if this is your landlord’s responsibility (for example it could be from a leaking roof that needs repairing). Or if the damp is caused by improper ventilation. To assess your options, click here.

What kind of ducting are you using?

Round Pipe:

Round ducting has the highest airflow performance, this is due to a wider diameter increasing its free area. The lack of corners also decreases resistance within the pipe, which allows for higher airflow rates and higher rates of ventilation.

It is recommended for most applications where space is available for installation. Its main purposes are for long ducting runs, whole-house ventilation systems, HVAC systems, bathroom, toilet and utility room extract fan venting, or any occasion where high rates of extraction are required.

Round PVC ducting pipe can be used for venting exhaust odours and steam from cooker hoods, although flexible ducting may be easier to install in many instances. 

Sizes are available from 100mm, 300mm, 500mm and 600mm diameters, with sizes between these dimensions also available. Both round and flat ducting have smooth inner surfaces to reduce air resistance and noise.

Pros & Cons of Round Ducting

Pros:

Cons:

High Airflow

Difficult to conceal

Less friction

Poor results in low-pressure systems

Lightweight

More expensive than flat ducting

Corrosion-resistant

Better for high-pressure systems

Designed for HVAC systems

Flat Channel Duct:

Flat channel ducting is ideal when a low profile is required due to lack of space. It can also be concealed and flush fit against ceilings and walls or within voids.

Please bear in mind that as a result of a lower free area, there is greater pressure created within a duct run. It is therefore essential that you check the manufacturer information for the fan you are planning to install within the run. 

If the fan is extracting at a rate that is greater than the duct run can cope with, there is potential for the fan to overheat and burn out. This is both costly and unnecessary. 

Flat channel plastic ducting is generally used for installations requiring low extraction rates such as bathrooms, toilets, and utility rooms. Sizes available from 110x54mm to 310x29mm.

Pros & Cons of Flat Channel Ducting

Pros:

Cons:

Corrosion-resistant

Creates more noise within duct run

Lightweight

Poor results within high-pressure systems

Easy to flush fit and conceal

Increased air resistance

Ideal for low-pressure applications

Be mindful of where you place your ducting in order to understand what kind of ducting you need, and where its access doors will be, which are vital in order to maintain the effectiveness of your ventilation by cleaning the ducting buildup at regular intervals.

Does Ventilation with plastic ducting actively remove mould?

Ventilation is a preventative method and will not get rid of mould that has already grown, in order to do that you need to remove the mould.

At I-Sells, we are here to help you combat the scourge of mould with the solutions that we offer, here are some options available in our mould control section.

It is our responsibility to clarify that even though these products will help you get rid of mould, it will still come back if you neglect the maintenance needed to have a mould-free environment.

Although our products will eliminate mould, if the source of the mould is a result of a leak or housing damage, the mould will return at some point. We urge you to deal with any leaks or damages along with treating mould.

Can you cut plastic ducting?

Yes, if choosing to install your plastic ducting yourself, you can cut the ducting.

If your pipe or flat channel needs to be cut, after measuring and marking with a pencil, use a table saw (mitre saw) to get a straight and neat cut through your PVC pipe. If you do not have access to a table saw, a hacksaw can be used.

Ensure when using a hacksaw you keep the cut as straight as possible. Using a pipe vice and a smooth controlled action on a handsaw will help you to achieve this.

If your cut is crooked, you will have a much harder time correctly joining lengths of pipe to each other or connecting parts. You will also find that pressure loss is a real issue.

Once you have your cut pipe, rub-down the point at which you made the cut with coarse sandpaper to give yourself a smooth surface to work with. Much like with cutting crookedly, if your cut is not clean, you risk pressure loss and connection issues.

Do I need ventilation systems and plastic ducting?

If you want the best possible prevention from the dangers of mould, ventilation systems along with having a regular ventilating routine is the most secure option you take. Proper ventilation is as simple as:

  • Opening a window and using an extractor fan during or after a hot bath/shower
  • Creating an airflow by opening windows on different sides of the home for around 20 minutes a day
  • Buying or making use of extractor fans within the home
  • Opening a window or using an extractor in the kitchen whilst cooking hot meals
  • (if living in a house) opening windows downstairs and upstairs, allowing the rising hot air to escape through upstairs windows, while cool, fresh air circulates in from the downstairs windows.

Track your humidity levels

Consider buying a Hygrometer. This device measures the levels of humidity in the air, which can indicate to you which rooms are creating the perfect environment for mould. This is a valuable maintenance and detection device that we offer.

Deal with it

If you find mould on your food, dispose of it and any other foods that may have been touching the moulded food, or open within the same area. If you find mould on any surfaces, clean it immediately with our anti-mould surface cleaner.

If mould reappears at a certain spot in your home, check to see if there is any leak or damage to the area that can be letting moisture in. If so, contact your landlord or trusted tradesman to fix the issue.

Browse our mould control options for the best possible solutions to dealing with mould.

Please note that these steps will not completely defend against mould if there are leakage issues in your home, but will certainly help to mitigate the growth of mould if done on a regular basis.
