Water Penetration And Brick Veneer!

How Porous is Brick Veneer?

Brick veneer is a popular option for both residential and commercial construction. It provides the classic look of brick at a lower cost and with lower weight than traditional brick, making it a popular alternative. One question many people have about brick veneer is its porosity. In other words, how much water can brick veneer absorb? In this article, we will explore just how porous brick veneer is.

What is Brick Veneer?

Brick veneer is a type of thin brick that is used as a decorative finish on the exterior of a building. It is typically installed over a substrate, such as a wooden frame, plasterboard or concrete wall, to provide an additional layer of protection as well as an aesthetic change. Brick veneers can be made from a variety of materials including clay, concrete, and stone.

Porosity of Brick Veneer

The porosity of brick veneer depends on several factors, including the material it is made from and its manufacturing process. Generally speaking, with our brick veneer being cut from real brick and therefore clay it is a porous material that can absorb a moderate amount of water. When installing in wet areas such as bathrooms and kitchens it is important that the surface they are being fixed to has sufficient waterproofing.

According to testing conducted by the Brick Industry Association, the average water absorption rate for brick veneer is approximately 7%. This means that brick veneer can absorb up to 7% of its weight in water. This rate of absorption is slightly lower than that of full-size bricks, which can absorb up to 20% of their weight in water.

The porosity of brick veneer can vary depending on its manufacturing process. Some brick veneers are molded using a dry-press process which results in a denser, less porous material. Other brick veneers are extruded, resulting in a more porous material.

The Importance of Porosity

While brick veneer is a relatively porous material, it is important to note that it is still a durable, long-lasting product when installed correctly. Proper installation, including proper flashing and weep systems, can help prevent water infiltration and protect both the veneer and the underlying substrate.

The porosity of brick veneer can also impact the energy efficiency of a building. Highly porous brick veneers may allow more heat transfer than less porous materials, leading to increased energy costs. However, there are external insulation systems available that can improve the energy efficiency of brick veneer applications.

A good way to prevent water retention is to seal the brick veneer using our brick veneer sealer.

Overall, brick veneer is a porous material that can absorb a moderate amount of water. Its porosity can vary depending on its manufacturing process. While the porosity of brick veneer can impact the energy efficiency of a building, proper installation can help prevent water infiltration and protect both the veneer and the underlying substrate. Brick veneer remains a popular option for those seeking the classic look of brick at a lower cost and with lower weight.
