The Benefits of Installing Ventilation Ducts in Concrete Slabs

Updated: Nov 6, 2024

More and more real estate projects are opting for the installation of flexible ventilation ducts embedded in concrete slabs, a method that combines energy efficiencyspace optimization, and aesthetic enhancement. A prime example of this approach is the Radio-Canada Tower 2 in Montreal, which utilized flexible ventilation ducts to maximize the efficiency of its ventilation system.

5 Reasons to Choose Ventilation Ducts in Concrete Slabs?


1.Space-Saving and Aesthetic Enhancement


The installation of Ventilation Ducts in Concrete Slabs helps to free up space and allows for more streamlined architectural designs. By eliminating the need for false ceilings, designers can create cleaner, more open spaces—especially valuable in high-end residential and commercial environments.


2.Improved Energy Efficiency


Ventilation ducts embedded in concrete benefit from the thermal mass effect of concrete, which helps regulate the temperature of the circulating air. According to GreenBuildingAdvisor, the thermal mass of materials like concrete plays a crucial role in reducing temperature fluctuations, contributing to improved energy efficiency. In winter, the concrete retains heat, while in summer, it aids in dissipating heat, reducing the need for heating and cooling systems.


3.Reduced Construction Costs


Integrating ventilation ducts into concrete slabs helps reduce construction costs by eliminating the need for false ceilings and additional supports for traditional ducts. Moreover, semi-rigid ducts installed over long distances require fewer joints, which minimizes the risk of leaks and reduces long-term maintenance costs.


4.Durability and Protection


Ventilation ducts embedded in concrete benefit from enhanced protection against physical damage and corrosion. The use of galvanized steel ducts or stainless steel ensures optimal resistance to corrosion, extending the lifespan of ventilation systems, particularly in demanding industrial environments.


5.Acoustic Insulation and Comfort


In addition to energy benefits, concrete provides excellent acoustic insulation. By integrating flexible ventilation ducts into structural slabs, noise generated by air circulation is significantly reduced, improving comfort for occupants in both residential and commercial buildings.


The Performance Choice with FLIXS SRGDP-TLO


To maximize the benefits of flexible ventilation ducts, the FLIXS SRGDP-TLO stands out as the ideal solution. Its smooth interior surface and double thermo-laminated steel wall ensure optimal energy efficiency while maintaining complete airtightness. Certified under ASTM E814 and CAN/ULC S115, the FLIXS SRGDP-TLO is one of the few ducts on the market that offers both fire resistance and complete airtightness, meeting the strict requirements of the building code. These certifications are crucial for ensuring both safety and performance, making FLIXS an essential choice for developers and installers who aim to optimize long-term costs while guaranteeing high-quality, reliable ventilation systems.In 2023, more than 840,000 feet of FLIXS ducts were manufactured, demonstrating the widespread adoption and reliability of this solution on the market. These figures highlight the growing importance of flexible ventilation ducts in meeting the diverse needs of modern construction projects.
