Masonry Veneer

Masonry veneer is a popular construction technique that involves using a thin layer of masonry, typically brick or stone, as a façade over a structural wall. This method is largely aesthetic, providing the appearance of a solid masonry wall without the associated weight and cost. Masonry veneers are used in both residential and commercial construction and can be constructed using various materials and techniques.

Components and Construction

Anchored Veneer

An anchored veneer is a common form of masonry veneer that includes an airspace between the veneer itself and the structural backing wall. This space is crucial for several reasons:

Drainage Plane: The airspace acts as a drainage plane, ensuring that any moisture that penetrates the veneer is directed away from the building by the use of flashing and weep holes.
Insulation: Additional thermal insulation can be included within the airspace, often using rigid foam boards to enhance the energy efficiency of the building.

Brick Ties

Brick ties are essential in anchoring the veneer to the supporting structure. These ties can take the form of:

Corrugated Metal Straps: Nailed or screwed to the structural framing.
Wire Extensions: Part of horizontal joint reinforcement in a fully masonry veneer or cavity wall.

Shelf Angles

In multi-story buildings, shelf angles are often used to provide horizontal expansion joints. These joints allow for the expansion and contraction of the brick veneer and accommodate potential movement in the frame. In such cases, the system is referred to as a curtain wall.

Types of Masonry Veneer

Brick Veneer

Brick veneer is a widely used type of anchored masonry veneer. It mimics the appearance of a traditional brick wall but is non-load bearing. The advantages of brick veneer include its aesthetic appeal and relatively easy installation compared to solid brick walls.

Stone Veneer

Stone veneer consists of a thin layer of stone used for decorative purposes. It is not structurally load-bearing but provides a natural and timeless aesthetic. Materials used can range from natural stone to manufactured stone products.

Applications

Masonry veneer is versatile and can be applied in various settings:

Residential Buildings: Provides an aesthetic finish and can increase the curb appeal of homes.
Commercial Structures: Offers a professional and durable exterior that can withstand environmental elements.
Renovations: Often used in remodeling projects to update the appearance of older buildings without the need for extensive structural changes.
