Alright, let's talk EIFS. You're probably checking it out because you know it's a fantastic insulation system, perfect for keeping those energy bills down. That's especially true with our hot summers and cold winters right here in West Jordan, isn't it? But once you start looking into it, you'll hear about two main types: 'barrier' EIFS and 'drainage' EIFS. It can get a little confusing, so I'm going to explain it simply, just for you.
What's the Real Difference?
The main idea behind EIFS (Exterior Insulation and Finish System) stays the same for both. You've got an insulation board, a base coat with mesh, and a finish coat that looks like stucco. The big difference, though, is how they handle water. And trust me, how a system deals with water is probably the most important thing you need to think about for any exterior finish, especially around here.
Barrier EIFS: The Original Way
Barrier EIFS is what you might call the 'original' version. Its whole job is to stop water from getting in, period. It depends on a continuous, waterproof finish coat to shed all the rain and snow. Imagine it like a really good raincoat for your house. If water can't get past that outer layer, it can't get into your walls. Simple enough.
Pros of Barrier EIFS:
- Cheaper Upfront: Generally, it costs a bit less to put in initially because there are fewer parts and steps involved.
- Great Insulation: You still get all the thermal benefits of EIFS, which is a huge plus for saving energy.
- Clean Look: It gives you that classic, smooth stucco appearance without any visible drainage elements.
Cons of Barrier EIFS:
- Vulnerable to Water Traps: This is the big problem. If water gets in — say, through a poorly sealed window, a small crack, or a hole for a light fixture — it can get stuck behind the system. Since there's no way for it to drain out, it can just sit there, causing rot and mold in your sheathing. I've seen this happen in older homes, especially those built in the 90s, where the detailing just wasn't as thorough as it should've been.
- Hard to Fix: Finding and repairing the source of a leak can be tough, and repairs often mean cutting into the system itself.
Drainage EIFS: The Smarter Version
Drainage EIFS, sometimes called 'water-managed' EIFS, came about to fix the problems that popped up with barrier systems. It's built knowing that some water will eventually get behind the finish coat. So, instead of just trying to block it, it gives that water a way to get out.
How does it do this? It adds a few key layers: a fluid-applied air/water barrier right over the sheathing, and then a drainage plane (often a grooved insulation board or a drainage mat) between that barrier and the EIFS finish. This creates a tiny gap that lets any water that gets past the outer EIFS layers drain down and out through weep holes at the bottom of the wall.
Pros of Drainage EIFS:
- Better Moisture Control: This is its main strength. It's incredibly forgiving. If a little water gets in, it drains right out, stopping moisture buildup, rot, and mold. This is super important for our climate, where we get heavy snow melts and occasional intense rain.
- More Durable: By preventing moisture damage, the entire wall system simply lasts longer.
- Less Worry: You'll sleep better knowing your home's exterior is designed to handle water effectively.
Cons of Drainage EIFS:
- Higher Initial Cost: Because of the extra materials and installation steps, it usually costs more than barrier EIFS.
- A Bit More Complex to Install: It needs careful attention to detail to make sure the drainage plane and weep holes work correctly.
Which One Should You Pick for Your West Jordan Home?
Look, I'm going to be honest with you. For a home in West Jordan, or really anywhere in Utah, I always recommend drainage EIFS.
Why? Because our weather isn't always predictable. We get snow that piles up against walls, then melts. We get sudden thunderstorms. Our homes settle a bit over time, sometimes creating tiny cracks. And let's face it, no matter how good the installation, things happen. A drainage system gives you that critical backup. It's like having a safety net, if you think about it.
While barrier EIFS might save you a few bucks upfront, the potential for costly moisture damage down the road just isn't worth the risk. I've seen the headaches and expenses homeowners face when water gets trapped. Investing a bit more in a drainage system now is a smart long-term decision for the health and longevity of your home.

Final Thoughts
Don't cut corners when it comes to your home's exterior. The wall system is what protects everything inside. A well-installed drainage EIFS system will give you the insulation benefits you want, plus the comfort of knowing your home is protected from the elements. It's a solid choice for any homeowner here in West Jordan.
