Are you shopping for a ceiling fan but aren’t sure which material is best for the blades? Here’s what you want to know.
Ceiling fan material can impact performance, longevity and looks of a ceiling fan as well as produce a different noise. For most applications, plastic or wooden ceiling fan blades are the best overall compromise. Metal usually moves the most air but is noisier. MDF is cheap but doesn’t last long.
Let’s dive a little deeper into why blade material is important and what works best for you.
Does Ceiling Fan Blade Material Matter?
The material of the blades of a ceiling fan can impact quite a few things like;
- Fan performance
- Weather resistance
How the blade material can impact the looks of a fan should be pretty obvious. Wood looks great but can’t be made as thin as other materials so it will look different than metal blades that can be very thin. This will lead to a difference in the shape of the blade which in turn also changes the performance of the fan.
Design is personal and you should pick what you like and fits in your interior but be aware that there are a few other things that the material can change.
Different materials have different weights and different degrees of flexibility and weather resistance. Some materials can withstand moisture or even rain perfectly fine while other materials turn into mush after seeing a rain drop. That means a difference in where you can use certain materials.
Heavier blades are more difficult to get moving and keep moving. The heavier the blades, the more stress is put on the motor which means less performance and longevity.
Also, the way certain materials vibrate when moving air creates different noises.
Ceiling Fan Blade Materials Characteristics
Ceiling fan blades are made from one of four materials:
They all have their own characteristics and applications. In some cases there can also be a combination of the different materials.
Let’s take a look at the different ceiling fan blade materials and what the pros and cons of each are.
Metal Ceiling Fan Blades
Metal fan blades are popular for those who want the most possible airflow. Since they are so heavy, metal blades will cut right through the air providing great airflow. This is because they can be thinner than timer or plastic blades and still be strong enough.
The reason this is not the most popular choice is that they are not very cost-effective. Metal may cut through the air, but it is also very heavy. This added weight will cause the fan motor to struggle to run the fan at times. This means that metal blades may cost you more when it comes to energy use.
Also, be careful using metal blades as they can easily rust if too much moisture is introduced. They can also be a bit noisier compared to other materials. Because of the thinner shape, they create a bit more turbulence which you can hear.
Timber Ceiling Fan Blades
Timber ceiling fan blades are the most common blade material. They look good, last long and produce a pleasant sound. There are some limitations in how wood can be shaped so they aren’t necessarily the most efficient blades. Wood is also quite heavy which puts more load on the motor and mounting point.
Of course it largely depends on the type of wood that’s used as well. Balsa wood is common which is very light, much lighter than MDF for example. Oak and Walnut are also seen and while they look great, are very heavy. Those woods are more expensive to buy but also to run because of the higher drag on the motor.
Some manufacturers have begun to combine timber blades with plastic to allow it to be more effective without sacrificing sound. Plastic inserts also prevent the blades from warping.
Wooden blades can warp with humidity and temperature changes which is not a huge deal but can have small impacts on effectiveness.
For most people, the looks are a leading factor when buying and as long as you’re aware of the downsides, it’s still a good choice for many people. You spend a bit more for a nicer looking interior, people do that all the time with other furniture so why not a ceiling fan.
Compound/Pressed board Ceiling fan blades
A cheap option for fan blades is pressed board also known as MDF. These are cheap to manufacture but do have some downsides. They’re quite heavy, heavier than some wooden blades in fact. That means a high load on the motor. MDF blades also have to be thick to have the proper rigidity and structural integrity.
MDF is more resistant to humidity and temperature changes than wood as long as it’s within the ‘normal’ range for indoors. However, MDF blades deteriorate very quickly when exposed to liquids or high humidity. These are not suitable for wet or even damp use.
MDF is the cheapest but you’re also the most likely to having to replace them soon. They can be made to look like wood but it doesn’t have the same longevity.
Plastic Ceiling Fan Blades
Plastic (ABS to be more specific) blades are growing in popularity as they are cost-effective, and can be easily molded into any shape you want, giving you more options for different blade designs.
Also, plastic blades are very lightweight, which means that your fan motor will not struggle to move them so the fan can spin faster and move more air. At the same time it’s rigid so it moves air efficiently at all speeds. This will save you on energy costs and allow you to circulate more air with these blades.
Lighter fan blades can also help your fan motor last longer as the motor won’t struggle as much to work.
Since plastic also doesn’t change or warp when wet means that this is a good material to use in damp or wet conditions.
The downside of plastic is that it doesn’t really look good for classic designs. It can be made to work well for modern designs however.
