Over the years since its creation, Ecoduct has become one of those things that people mistake for a generic term for ducts. It’s similar to how rollerblades, jacuzzis, and scotch tape are used as terms for their related products despite actually being brand names.

While that’s not necessarily a bad thing, some people might be under the mistaken impression that Ecoduct is all there is. Because you’re paying for the marketing and the brand, you might actually be paying more for Ecoduct than if you were to buy your duct parts from Tradesman Manufacturing.

If you’re looking for a cheaper and more effective version of Ecoduct, we’ve put together all the facts in this blog post.


What is Ecoduct?                                           

Ecoduct is a company and product based in Australia. Made out of PVC instead of metal, Ecoduct bills itself as an alternative to sheetmetal ductwork. The main difference between metal and PVC in the HVAC industry is that metal sheets are bent into the desired shape. PVC ducts, on the other hand, are made of liquid plastic poured into molds.

Pros of PVC ducts (Ecoduct)

PVC is more resistant to corrosion, which makes it a good option for mitigating risk, especially in larger commercial buildings. Because it is more resistant to corrosion, it can be placed closer to moisture. That makes PVC a more versatile material, allowing a builder to design a home with heating and cooling in the floor rather than the ceiling.

Cons of PVC ducts (Ecoduct)

While there are many good uses for PVC ducts, there are also many reasons to consider a different option. PVC is more expensive to manufacture and can weigh twice as much as metal ductwork, which is very thin and lightweight. Because of its weight, it can end up complicating the design of a house and installation.

When you use PVC ducts, you are effectively locked into using the same material in all of your ductwork. This goes for when you use metal ductwork as well. However, remember that PVC requires specific plastic molds to make the shapes you need. That means getting the exact shape and size you need could be difficult—and expensive, especially when PVC can be prone to cracking.

Most importantly, PVC is not as effective for heating buildings. While Ecoduct is great for carrying cold air and water in Australia, PVC is just not as helpful in Canada. PVC has a universal maximum temperature of 140°F, while metal ducts can handle as high as 700°F. Stainless steel has a temperature range as high as 1650°F.

Pros of metal ducts (Tradesman)

Metal ducts are the most common type of ventilation systems, and for good reason.

Metal ducts allow for the best energy conservation, reducing condensation and allowing for greater control of the desired temperature. That not only means a more comfortable temperature, but also a greener way of living.

With the versatility of its construction, metal sheets can be easily bent and shaped to accommodate whatever function you need. That means that finding custom solutions is easy and cost-effective. Metal ducts are typically very thin and lightweight, making it easier when building and designing a property. At Tradesman, all of our ducts are also beaded every 12” for added strength.

At Tradesman, all of our ducts and duct fittings can be purchased separately as needed. However, all our fittings are made to fit our Tradesman duct, making installation much easier if you have the same products. Easy installation is a win-win when it saves you both time and money!

Cons of metal ducts (Tradesman)

Metal ducts can be more susceptible to corrosion compared to PVC. That means that it should be kept further away from moisture in the ground. However, HVAC systems are typically installed in the ceilings for this very reason and builders will be familiar with how to design it. Tradesman also offers an optional stainless, aluminum, or satin coat to protect your ductwork for longer!
