Balcony Inspection Vents

Removable Balcony Vents to comply with SB721 and SB326

Balcony Inspection Vents were developed in response to SB-721 and SB-326, which were enacted to address significant concerns with “Exterior Elevated Elements” and the need for repairs in 19% of such structures. As per the new laws and the California Building Code, one of the mandatory requirements is the installation of vents on balconies and similar structures. These vents enable easy access for inspectors to assess the structural integrity of the extended elevated element. Our Balcony Inspection Vents not only comply with SB-721 and SB-326, but also undergo rigorous testing, including California Building Code Chapter 7A, ASTM E2886 & E119, and hold approvals from Cal Fire. Moreover, they meet all requirements for use in high-risk wildfire areas (WUI).

EverKem Fire Stop 814

Use EverKem Fire Caulking

  1. We recommend using EverKem 814+, intumescent fire caulking with all installation of Vulcan Vents.
    • Our round eave vents are the exception: EverKem 136, mortar based caulking should be used when mounting hardware isn’t an option and flanges are minimal.
  2. INSTALLATION: Prior to installing the vent, run a bead of EverKem behind the nailing flange to ensure an air tight seal where the vent meats the building material. This ensures that no gaps are present between the vent and your building material where flying embers might enter!

Why are balcony inspection vents required?

SB 326

Senate Bill 326, also known as SB-326, was enacted in California to address critical concerns regarding the safety and structural integrity of “Exterior Elevated Elements” in multi-family residential buildings. The bill was a response to unfortunate incidents involving balcony collapses, emphasizing the need for preventive measures and regular inspections. SB-326 mandates the installation of balcony inspection vents on these structures, facilitating easy access for inspectors to evaluate the core structural components. By requiring the use of these vents, the bill aims to enhance safety standards, prevent potential accidents, and ensure that balcony structures are properly maintained and in compliance with the California Building Code. The implementation of balcony inspection vents as per SB-326 demonstrates a proactive approach to safeguarding the well-being of residents and enhancing the overall structural integrity of multi-family residential buildings in California.

Senate Bill 721, also referred to as SB-721, was enacted in California in response to a series of tragic incidents involving the failure of “Exterior Elevated Elements” in multi-family residential buildings. The bill was introduced to address the need for enhanced safety measures and regular inspections of these structures to prevent future accidents. SB-721 specifically mandates the installation of balcony inspection vents, which provide convenient access for inspectors to evaluate the structural integrity of balconies and similar elements. By requiring the use of these vents, SB-721 aims to ensure that property owners and managers are proactive in maintaining safe living conditions for residents. The implementation of balcony inspection vents as per SB-721 emphasizes the commitment to improving the safety standards and overall well-being of residents in multi-family residential buildings throughout California.

Cost-effective maintenance and inspections
save money in the long run

Inspecting a balcony without a dedicated balcony inspection vent can not only be costly and destructive but also compromises the safety of homeowners and their loved ones. Without a proper access point, conducting thorough inspections becomes challenging, increasing the risk of overlooking potential issues that could pose a danger. A balcony with hidden structural problems, such as rot, deterioration, or weak supports, can lead to catastrophic failures, jeopardizing the well-being of those using the balcony. By installing a balcony inspection vent, homeowners ensure the safety of their families by providing inspectors with easy access to thoroughly assess the balcony’s condition. This proactive approach allows for early detection of any underlying issues, enabling timely repairs or maintenance to prevent accidents and protect the occupants from harm. Investing in a balcony inspection vent not only saves costs and minimizes damage during inspections but, more importantly, it prioritizes the safety and peace of mind of homeowners and their loved ones.

We called to find out if the Vulcan vents would meet the California ember retardant standards for fire. Nate Oliver took our call and spent nearly half an hour providing us with in depth information, guiding us through their website to view and discuss each alternative and even taking us to another website to view the Vulcan product on it. He discussed different options for installing the vents and the specific type of caulk we needed that also met the fire-wise requirements. Then he guided us to the section where we could download the documentation for our insurers. We came away from this conversation with exactly what we needed and the documentation to back it up. I can't say enough good things about Nate's customer service. His knowledge was remarkable, his eagerness to ensure that we ordered the exact right vent was so reassuring, and we immediately posted the Vulcan Vent information on our neighborhood Facebook site so that others in our fire-prone area can obtain the right products for their venting needs. If I could give 10 stars I would.

After a few months of having the new Vulcan Vents installed in our eaves, I am extremely impressed with the updated design. The 1/8” fine mesh on the outside prevents insects from getting into the ‘honeycombs’ and the 1/4” mesh on the inside adds coverage from attic side to the ‘honeycombs’ without reducing airflow. The ingenious design allowed plenty of airflow to the attic through this past summer, but if a fire were to come our way, it is comforting to know that these same vents will expand and close off, preventing embers or direct flame from being able to enter the attic. A bonus to the design, as you can see in the picture below, is that the thickness of the vent prevents being able to see into the attic and preventing attic insulation from getting pushed up against the outside screen, which somehow tends to happen whenever access is made to attics. Aesthetically and design-wise, these vents provide a solid home hardening solution that is easy to install. These vents are a must in my opinion for any homeowner who has any plants near their home that could generate significant heat during a wildfire. The combination of the 1/8” mesh and the coating that expands and cuts off all airflow into the attic when exposed to radiant heat are the perfect combination to prevent embers, radiant heat, and direct flame from entering the attic space. My experience with this local company (Loomis, California) is that they have excellent customer service and go above-and-beyond to ensure that their customers are satisfied with the quality of their product.
