About Insulated Flood Vents
This series is used for a garage or conditioned space where flood protection is required but air ventilation is not desired. For situations where a sealed crawlspace is being utilized in a floodplain, flood protection is still required and the Insulated FLOOD VENT series is the perfect fit for those applications.
The vent door is latched closed until it comes in contact with flood water. Entering flood water lifts the patented internal floats which unlatch and allow the door to rotate open. This allows the flood water to automatically enter and exit through the frame opening, relieving the pressure from the foundation walls. Certified flood debris clearance is demonstrated with a 3” diameter opening when the flood door is activated.
The flood door contains a 2” insulated core that has an R-value of 8.34. There is also a felt weather stripping that lines the entire vent frame helping to keep the enclosure as insulated as possible.
Flood Resistant Materials
The Smart Vent product line is constructed out of Marine Grade Stainless Steel and is 100% made in the United States. T316L Stainless Steel is renowned for its ability to withstand usage in harsh marine and chemical environments, ensuring that our products will handle everything Mother Nature throws at them. Because T316L Stainless Steel is known for its strength and resistance to cracking, dents, and embrittlement it’s utilized in high profile projects meant to last decades. Alloyed with Chrome, Nickel, and Molybdenum, T316L Stainless Steel takes the strength of steel and adds protection making it the ultimate flood resistant material.
NEW ENERGY EFFICIENT UPGRADE AVAILABLE
FOR 1540-520 MODELS
The NEW Flood Vent Sealing Kit (Model #1540-526) works to create a tight seal behind the vent opening and finish off the interior space while the vent is not in use. When a flood event occurs, the pre-cut Homasote® material blows out from the area in the center, creating a now unobstructed opening to allow the insulated flood door to open automatically. Because the Homasote® is composed of 98% recycled material, it is biodegradable and will decompose leading to less post-flood cleanup.
This simple, energy efficient upgrade is for any new or existing SMART VENT Insulated Model #1540-520 in your home or business, which exceeds the 2018 energy codes. View Flood Vent Sealing Kit for more product information.
