Avoid Stone Veneer Failures: Get up to Speed on Building Code Requirements for Rainscreen

Avoid Stone Veneer Failures: Get up to Speed on Building Code Requirements for Rainscreen

For a contractor living in the Eastern half of the U.S. or along the West Coast states, you know the issues you can have with moisture getting into your projects. Rain and humidity can wreak havoc on stone veneers when any bit of moisture settles in behind the masonry and causes a leak or mold situation.

For that reason, the International Building Code passed a requirement for the incorporation of a drainage plane behind stone systems. Frequently referred to as “rainscreen,” this space or drainage material needs to be no less than 3/16 inch depth behind the stone. Rainscreens are available in a range of materials including entangled mesh and plastic or foam products with drainage avenues.

Dell Nolt, field service representative of Westlake Royal Stone Solutions recently provided an educational workshop to professional contractors in order to educate them on this new requirement. He covered the official code, where contractors can find its official language, why it’s important, the materials on the market that are compliant with the code and how to install it.

According to the code, adhered masonry veneer will follow the 2018 Section R703.12​. Its installation will refer to the 2021 Exterior Plaster section:​

  • R703.71—installation of lath and all accessories​
  • R703.7.3—water-resistive barrier including a rain screen drainage space

Best practices to achieve this rainscreen include:

  •     Sheathing​
  •     WRB​
  •     Drainage medium​
  •     Mortar screen/WRB​
  •     Lath​
  •     Scratch coat​
  •     ACMV.

Nolt says there is often a lack of education in the industry when a new code requirement comes out. Contractors just aren’t hearing about it. He hopes Westlake Royal Stone Solutions can be a resource, informing the industry on how to stay compliant with installations.

“We’re trying to help you protect your business so you can utilize this information and pass it on to your clients,” Nolt explains. “As an industry, we want to make sure we’re doing the best thing for our clients so they can enjoy the longevity of the product and it performs as it’s designed to.”

He adds that it’s not hard to understand the logic behind the code. “If you Google stone veneer failure, it doesn’t take long to see a lot of horror stories about drainage issues and stone systems that have leaked for various reasons. We need great moisture management behind these systems to prevent bulk water intrusion or any other capillary failure that results from moisture getting trapped behind the stone system. It eliminates the potential for mold remediation or leak remediation.”

Moisture management is not something new. Nolt says that most contractors are already doing exactly what the code requires and the code is really just catching up with the science that’s been around for a while. “It’s not just unique to stone veneer. If you’re in the exterior cladding business, whether that be stone, cement, board siding or other types of veneer, moisture management is super important,” he says. “The code just makes sure that the industry addresses it from a universal standpoint.”

While this new International Building Code came out in 2021, Nolt says there is always some lag time in the adoption process.  Pennsylvania was the first state to adopt the process but it’s required in all states that fall into the moisture zones on the climate map. This is Moist Climate A, which includes the Eastern half of the U.S. via a line split down Minnesota through the center of Texas and Marine Climate Zone C, which runs along the West Coast and Pacific Northwest including Washington and the California coast. The only states not requiring this code are in Dry Climate Zone B, which includes Nevada and Colorado.

While adding an extra step is not something contractors always want to hear, Nolt says it’s not really that much additional work or monetary inconvenience. “We’re talking about an ancillary type of product. The cost is not significant; it’s really just a few cents on a square foot. The significant cost comes if there is a failure of the product if moisture gets in. So this is really a kind of cheap form of insurance to prevent that.”

There are already products on the market to help contractors address the code and with the new requirement, Dells predicts more products will become available as the demand increases. One product already available is made by Cultured Stone, called Drain-N-Dry™, a pre-rainscreen material that provides moisture drainage, and it has an added feature many others do not provide.

“It has some technology behind it to address air circulation behind the wall system. It creates some airflow to become a ventilated type of system for moisture drainage,” Nolt explains.

For contractors looking for information or solutions to comply with the code requirement, they can contact Instone.

As the old saying goes: An ounce of prevention is worth a pound of cure.” By adhering to the code and adding a rainscreen to stone veneer projects, it helps the industry as a whole ensure against moisture damage and have many happy customers with beautiful stonework on their homes and commercial properties for years to come.

Boost Your Home’s Value with Pangaea® Natural Stone for Added Curb Appeal

Curb appeal. We’ve all heard about it, but how do you get it and what’s the best way to increase curb appeal while getting a great return on investment when you decide to sell? The front of your house greets guests and passers-by alike. Its appearance can turn heads or make heads shake. Your house’s exterior beauty, or “curb appeal”, is one of the biggest factors that determine your home’s value and street cred.

A home’s entrance featuring Pangaea® Cambrian Fieldstone.

Curb appeal is especially important for those considering selling or being compliant with homeowners’ association maintenance regulations. It also plays an important role in just being a responsible neighbor, keeping the neighborhood looking nice, and raising property values.

For a quick and easy way to boost your home’s curb appeal, let us introduce you to natural stone veneer. Our Pangaea ® veneer can instantly add an attractive finish to a home’s entryway, siding, walls and columns. It is made from real stone, cut thin and designed to be affixed to vertical surfaces, giving the appearance of full-bed stones.

What a difference one choice makes. WestCoast® Fieldstone makes the entry stand out!

We spoke with Andrew Everleigh of Environmental Pools, who has completed dozens of home improvement and masonry projects using Pangaea® stone to enhance a home’s appearance. He said one of the biggest reasons to go with Pangaea® was the look of the stone. “The way the stones are cut and the tightness of how they look together. I get a lot of feedback on how people like the simple, modern look that Pangaea® gives them.”

He says the quality is also a benefit, “There’s a lot of thin veneer out there. If someone is looking for a high-end stone veneer, Pangaea® is it.”

The Difference Between Natural Stone and Manufactured Stone

While it may be hard to detect by the untrained eye, there is a difference between natural stone veneer and manufactured (aka cultured) stone. Natural stone comes from Mother Nature herself, quarried from the earth and thinly sliced to make a veneer instead of using a full-bed stone. Because it’s created by nature, it’s naturally sustainable, can withstand weather conditions and gives a unique appearance with textures and tonal variations that look aesthetically beautiful.

Manufactured or cultured stone is man-made and designed to mimic natural stone in appearance. It is usually made of concrete and aggregate materials and is stained or painted to look like natural stone colors. Therefore, it may not be as durable as natural stone and can fade or erode over time or in harsh weather conditions.

The difference may be in cost. While cultured stone may appear to be lower cost upfront because it’s not as durable, it may need to be replaced down the road. Because natural stone is made to last by the earth, the value is in its durability. However, Pangaea® natural stone veneers are comparably priced to cultured stone right at purchase, so it’s a win-win!

How to Use Pangaea® Natural Stone Veneers on Your Home

Everleigh and his team often use Pangaea® for applications where they are not able to do a full-set or full-bed stone; it provides a lighter weight, sleeker finish than bigger stones. It’s also more cost-effective to use veneers versus full-bed stones. While Pangaea® comes in a number of finishes, he said his team uses a lot of Ledgestone and Ashlar and sometimes will mix it with Castlestone for a unique look.

For a homeowner who’s been looking at their same house for a number of years, sometimes it’s hard to know where to make improvements for aesthetic value. That’s where Everleigh’s team or a landscape architect comes in to provide guidance.

“Either our team or a landscape architect would work with the homeowner to create a design and color palette and then we would come in and build it.”

He says the first step is taking a look at the architecture of the home and the overall layout to the outside environment and determining the type of Pangaea® stone that will work best. For example, for more of a country-style, old-fashion feel, they would use the Fieldstone. For a more modern look they would go with a Ledgestone. The homeowner would determine the color palette they like best—greys or tans, or a mixture based on the overall theme of the property.

Everleigh said each area has a prominent type of architecture. New England is generally a lot of grey and brown tones, while more of a Tuscan style may be popular in other areas. He says it’s best to turn to the guidance of an expert rather than DIY to make sure the design matches the architecture of the house. “They can help you narrow down the color and source samples so the homeowner can see and feel the choices available,” he says.

Pangaea® comes in a large variety of color and style options to fit the design you want to create. View our selection here.

Where to Use Natural Stone Veneers to Improve Curb Appeal

One of the benefits of using Pangaea® thin stone veneer is the way stone veneer can transform and upgrade the look of the home. Here are a few ways to use it for better curb appeal:

Entryway: Thin stone veneer can provide a completely new look to your home’s front door area and create interest and contrast.
