Why Brick Vents Are a Better Ventilation Option Than Weep Holes

3479631_5bb94a1fUsing brick masonry in the creation of structures has many benefits. Not only do bricks produce some of the most eye-catching architecture, but they’re also very sturdy and durable. Many home and business owners have come to really appreciate this noise-blocking, fire-resistant and termite-immune building material. Furthermore, bricks contribute to the eco-friendly cause.

However, while there are many advantages to building with masonry, there can also be a major downside if brickwork isn’t taken care of properly. Bricks are actually porous and soak up moisture like a sponge. Which means, in stormy weather, water is absorbed and can accumulate until mold, spalling or efflorescence occurs. The most common methods for ventilating brick walls are weep holes and brick vents, but read on to find out why brick vents are the more superior option.

Weep Holes

Since brickwork is known to take in a lot of water during rainstorms, weep holes have been used by masons for years to help with the drainage of walls and for ventilation purposes. Weep holes are created by leaving small openings near the bottom of a brick wall at consistent intervals between bricks. While these holes are purposely left by bricklayers, property owners often mistakenly believe their home or business is just missing mortar in some areas, and the presence of these openings can take away from the building’s aesthetic appeal. Another disadvantage to weep holes is that these openings are big enough to give insects and rodents the perfect spot to sneak right into a building and take up residence. This can cause property owners a big headache with pest infestations. Problems oftentimes arise with weep holes because they simply aren’t large enough to provide suitable ventilation for an entire brick wall.

Brick Vents

While it’s necessary for brick homes and commercial buildings to be built airtight, there has to also be a significant amount of “breathing” room. Brick vents are a much more effective solution than weep holes as they provide a more spacious passageway for airflow, increasing a brick wall’s chances of drying out quicker and more thoroughly. Brick vents are sized to match the bricks already forming a wall, eliminating the need for unsightly holes while keeping the aesthetic quality masonry is known for intact. Since weep holes only work for ventilation if they are left completely open, it renders them useless when they accidentally become filled in by mortar droppings, which is not an uncommon occurrence. Brick vents aren’t susceptible to this kind of compromising situation.

By keeping moisture and unwanted creatures on the outside of your property, brick vents are an efficient way of preventing the many complications a property owner can face when their brick walls become wet.
