New ICC International Drainage Plane Requirements Behind Stone Veneer Systems: Ensuring Building Longevity
Understanding the Importance of the International Code Council’s (ICC) Requirements for integration of a 3/16” minimum depth Ventilated Air Space behind Stone Veneer Systems.
What are the current International Drainage Plane code requirements in 2023? What is the significance of this “Ventilated Air Space” in Stone Veneer Installations?
Stone veneer has a longstanding reputation as being a popular choice for enhancing the aesthetics and durability of both interior and exterior spaces. Whether it's the timeless elegance of stone fireplace surrounds or the rustic charm of stacked stone accent walls, stone veneer offers a versatile and visually appealing solution.
A traditional stone veneer installation over a wood framed structure (say for instance, a house exterior) involves a process of adhering individual stone pieces to a wall using a pre-blended masonry mortar. After the building is wrapped in a water resistive barrier, known most commonly as house wrap, a galvanized metal wire lath is fastened onto the wall, to then receive a mortar scratch coat spread evenly overtop. The back of the stone is buttered in setting mortar and the stone is pressed into the wall, just as with installing a natural thin stone.
Although in this traditional installation the building is properly flashed protecting fully from water intrusion, new modern products and code procedures have since been developed to create even more breathability in the wall system, allowing for any trapped moisture to drain more freely from between the stone veneer and the building’s water resistive barrier.
In certain areas of the US, these new drainage procedures have become requirement by the International Code Council, ICC. Adhering to the new international drainage plane requirements in these regions is crucial to ensure the longevity and structural integrity of stone veneer installations.
An Overview of International Building Code Requirements
In recent years, international building codes have been updated to include specific requirements for exterior stone veneer installations in designated climate zones of the United States. As with all updates to national building codes, these code updates aim to address the potential moisture-related issues that can arise when a stone veneer system is installed improperly. Namely, in the waterproofing and underlayment process before the stonework can begin.
The Role of A “Ventilated Air Space”
Understanding the Ventilated Air Space and Benefits of Ventilated Air Space within Stone Veneer Installations
Stated in the Code, this drainage plane is referred to as “A Ventilated Air Space,” a 3/16” minimum gap between the stone veneer and the underlying substrate, allowing air movement and releasing of any trapped moisture. This space acts as a drainage plane, ensuring that water and humidity are directed away from the building envelope, further reducing the risk of water infiltration and potential damage down the road.
How can this Ventilated Air Space Be Achieved?
