Known in full as Exterior Insulation Finishing System, EIFS is a type of cladding that offers unrivaled energy efficiency. It’s quite durable and once installed it leaves behind a decorative finish.
EIFS is also versatile. That is, you can apply it to various construction materials ranging from brick to pre-cast panels. However, can you use EIFS on metal studs? That’s what you’re going to find out in the review below.
Can You Apply EIFS on Metal Studs?
Yes, EIFS can be applied on metal studs. Of late, many homeowners and contractors are gravitating towards metal stud framing because it’s durable, lightweight, and cost-effective.
The good news is that EIFS is compatible with metal stud framing. However, proper installation is a crucial factor that determines the longevity of both materials.
When applying EIFS on metal studs, certain factors such as moisture management need to be properly addressed.
However, as long as the installation is done correctly, EIFS on metal studs can provide an energy-efficient and durable system that’s also quite attractive from the property’s exterior.
How to Apply EIFS on Metal Studs?
Step 1: Prepare the metal studs
You just can’t attach an exterior insulation finishing system to metal studs. Preparation is key in ensuring a strong bond between these two materials. So, begin by thoroughly cleaning the metal studs.
Ensure they are free of debris and dust. Apply some primer to the metal studs to improve adhesion and seal the metal studs to prevent corrosion.
Step 2: Attach a rigid insulation board
The next method entails attaching an EIFS-approved rigid insulation board. I always advise my readers to attach the rigid board to the metal studs using a combination of adhesive and mechanical fasteners. This ensures the bond is strong.
Please attach the board with the seams running vertically, this enables the board to fight against moisture penetration.
Step 3: Apply a water-resistive barrier
Moisture is the number one enemy when it comes to EIFS on metal studs. That’s why a water-resistant barrier is a must-have!
Install a water-resistant barrier over the rigid insulation board. Make sure that the seams on the board are thoroughly covered.
Step 4: Spread the base coat
A base coat serves two purposes when applying EIFS on metal studs; it creates a foundation for the finish coat and two, it acts as a substrate for the reinforcing mesh which will be installed in the next step. The base coat doesn’t have to be very thick.
Step 5: Attach the reinforcing mesh
Never skip on installing mesh on an EIFS system. This mesh is what’s responsible for holding the entire EIFS system together. Without it, the chances of failure are very high. Before the base coat dries, attach the reinforcing mesh.
Step 6: Finish up with the final coat
It’s now time to add the decorative element to your EIFS. Complete the project by applying the final layer and you’ll have successfully applied EIFS on metal studs.
Is EIFS the Best Insulation for Metal Studs?
From a professional point of view, I can confidently say that EIFS is one of the best insulations for metal studs.
However, there are many different types of insulations such as spray foam and fiberglass which have several advantages over EIFS. So, we can’t assume that EIFS is the best. But it’s one of the top choices!
Be as it may, several reasons make EIFS an ideal insulation for metal studs, which include;
• With EIFS on metal studs, you’re guaranteed high energy efficiency and indoor comfort. External insulation finishing systems reduce the transmission of heat to metal which is a pretty good conductor. As a result, homeowners with such a setup enjoy lower energy consumption and bills.
• EIFS is also quite versatile when used on metal studs. You can choose from a wide range of finishes which gives you so many options when it comes to exterior aesthetics.
• If you follow the installation method I have discussed above, you won’t have to worry about the effects of moisture damage. EIFS can better stand up against moisture penetration, unlike most types of insulation systems.
• A well-applied EIFS on metal stud framing can last for a very long time. That means you will get your money’s worth.
• Apart from thermal insulation, EIFS on metal studs will block noise from neighbors and roads. so, you’ll enjoy living in a quieter home.
What are the Drawbacks of Using EIFS on Metal Studs?
• Installing EIFS on metal studs is NOT a walk in the park. This is a procedure that requires precision and thorough planning. This is the biggest challenge associated with applying EIFS on metal studs.
• Even though exterior insulation finishing systems are budget-friendly, the type of finish you decide to use can have a huge impact on the initial costs. The more sophisticated the finish you want is, the more likely it will set you back a few extra hundred dollars.
• EIFS on metal usually requires additional fire barriers to pass building codes and also for your safety.
• The other drawback of an EIFS on metal studs is that it requires regular inspections and maintenance. This is done to mitigate the side effects of water damage.
What Are the Common Mistakes to Avoid When Applying EIFS On Metal Studs?
Applying EIFS on metal studs is a straightforward process. And as long as you follow the guide shared above, everything will work perfectly. But hey, we’re human beings, and it’s normal for us to make some mistakes.
Since prevention is always better than cure, here are some common problems people make that you should avoid when applying EIFS on metal studs;
• Underestimating the importance of hiring a skilled EIFS installer. Unless you’re very good at installing such systems, there’s no need to go at this alone.
Also, you need to understand that there are different types of EIFS systems and each needs to be installed by an individual with vast knowledge and experience.
• Choosing a low-quality EIFS system. I get it that times are very tough. But going for a cheap EIFS means that you’ll be compromising quality. I don’t need to tell you what follows when you apply low-quality EIFS on metal studs.
• Forgetting to clean and prime the metal studs before attaching EIFS.
• Failing to maintain the EIFS on metal studs. If you ignore this system, problems will slowly creep in and you’ll realize the extent of the damage when it is too late.
How Much Does It Cost to Apply EIFS on Metal Studs?
On average, the cost of applying EIFS on metal studs ranges from $8 to $14 per square foot. With this figure, calculate the size of the metal stud framing and find out how much you’re likely to spend on this project.
So, the bigger the coverage the more you’ll have to spend. It’s also worth mentioning that superior EIFS systems do cost more than their low-quality counterparts. Don’t forget to factor in the labor costs.
Sometimes the complexity of the installation can increase the cost of applying EIFS on metal studs. Homes that have lots of corners and curves are more likely to attract higher installation costs.
To ensure you get a bargain on this project, don’t settle for the first installer you come across. Request quotes from many contractors and compare them.
You can also reduce the workload by doing some of the above tasks yourself, like preparing the metal studs.
How Long Does EIFS Last on Metal Studs?
On metal studs, a well-installed EIFS can last for around 20 to 25 years. That’s a very long time compared to traditional insulation systems.
If you use quality EIFS materials and properly install them, they’ll last longer. However, if you don’t maintain your EIFS, the lifespan will be reduced significantly.
