Masonry veneer is an eye-catching architectural feature that adds visual appeal to buildings. When properly installed and maintained, brick veneer can last for centuries.
Sto(r) MVES offers high-performance masonry veneer systems for the most diverse range of aesthetics and structural requirements. The systems combine the beauty of natural stone, thin brick and cultured stone with CI and stucco performance.
Insulation
Masonry veneer is a great choice for new construction because of its excellent insulation properties. It can reduce energy costs and meet code requirements for thermal performance. It is also much lighter than solid masonry, making it easier to maneuver and install. It is also able to withstand freezing/thawing cycles and doesn’t degrade as easily when exposed to salt spray as traditional brick.
In order to maintain the integrity of the insulating system, it is important to use proper anchoring. The masonry veneer must be securely attached to the backing wall by corrosion resistant 8d common nails, or equivalent fasteners with greater pullout strength. In addition, a waterproof barrier should be applied to the exterior sheathing, such as building paper ship-lapped a minimum of 6 in. (152 mm) at seams, to prevent water from entering the wall cavity.
Sto offers a number of engineered wall systems that work with code compliant Adhered Masonry Veneer (AMV) of thin brick, natural or manufactured stone, ceramic tile and concrete to achieve high levels of air tightness, thermal efficiency and durability. For example, our StoTherm ci MVES system works with AMV of thin brick, natural or manufactured stone or ceramic tile to provide excellent thermal performance and air tightness in new commercial and residential construction. The system uses PROSOCO Masonry Veneer-Ties to achieve superior air infiltration control and moisture protection by limiting the penetration of water and gases. The ties are one-third less invasive than barrel-type ties and cause fewer breaches in the air barrier.
Durability
Masonry veneer is a durable, long-lasting cladding material. When used as the exterior wythe of a wall, masonry veneer can withstand harsh weather conditions like high winds and rain. When used as the cladding of a building, masonry veneer can add an element of traditional charm and curb appeal.
Brick cladding can help keep a home cool during summer and warm in winter. The dark masonry surface slows the release of heat into the interior. In turn, this helps the interior occupants stay comfortable.
The durability of a masonry veneer is also dependent on how well it is tied to the building structure. The brick must be anchored to the backing to prevent movement under wind and earthquake loads. The brick ties can take the form of corrugated metal straps nailed to the structural framing, or steel shear plates attached to vertical framing members. In addition, the back of a masonry veneer can be supported by non-combustible lintels that are secured to the wood framing members, or by supports attached to the wood frame.
In order to maximize the longevity of a brick veneer, it is important to install proper flashing and weeping devices. Brick is porous and will absorb water if not properly installed. When water accumulates in the wall it can cause mildew and molds if not adequately ventilated. Using weep holes, along with the appropriate mortar mix and installation technique, can mitigate this issue.
Aesthetics
Masonry veneer construction provides a visually stunning building exterior at a fraction of the cost of solid masonry. Its versatility enables homeowners and construction professionals to create visual designs that enhance the overall appeal of their structures. It also balances aesthetics with insulation and maintenance requirements, making it a popular choice for new and retrofit projects.
However, masonry veneer requires regular cleaning and inspections to keep it looking like new. These steps can be accomplished with water, mild detergents, or specialized stone cleaners to remove dirt and debris that may cause damage or staining. In addition, it’s a good idea to seal the surface of the veneer to protect against moisture penetration and freeze-thaw cycles.
Another benefit of masonry veneer is its lightweight construction, which helps reduce the structural load on the building. This is especially helpful for older buildings that can’t accommodate the weight of full masonry walls. Additionally, it can provide an energy-efficient solution for these structures by reducing thermal transfer through the wall assembly.
Versatility
Masonry veneer systems are high end installations that can be used over a variety of assemblies including continuous insulation (MVS-CI), stucco, cement board and CMU. They offer an easy to apply freeze-thaw stable bond that is backed by a one source warranty.
Masonry Veneer Systems are designed to meet the requirements of various code applications. They provide a cost-effective alternative to full-depth masonry construction without sacrificing performance or aesthetics. They are also available in a range of finishes to suit any design preference, such as tile, brick or stone.
As with solid masonry walls, a brick veneer wall must be tied back to the building frame to resist wind and earthquake loads. This is accomplished with a system of brick ties or masonry anchors that connect to the structural framing at each wall course and are fastened to the brick to resist horizontal movement. An air space between the structural framing and the veneer, called a cavity wall, provides rapid drainage and allows air to circulate throughout the cavity. This facilitates drying and reduces the risk of mold growth and rot.
In addition to structural requirements, a veneer must also accommodate small movements of the structure due to temperature changes or moisture-volume shifts. This is done by incorporating control joints at the same locations as those in the backing. This is similar to concrete masonry assemblies where horizontal joint reinforcement and controlled cracking is specified.
