In high-rise buildings, efficient heating, ventilation, and air conditioning (HVAC) systems are essential for maintaining a comfortable indoor environment. One innovative solution gaining traction in such constructions is inslab ducting. This method involves integrating the ductwork directly into the concrete slab during the building’s construction. Here’s why inslab ducting is particularly advantageous in high-rise buildings:

  1. Space Optimization:

High-rise buildings often have limited space for utilities. Inslab ducting maximizes the use of available space by running ducts through the concrete slabs, eliminating the need for additional ceiling or wall space. This efficient use of space is crucial in tall buildings where every square foot counts.

  1. Reduced Noise Transmission:

Inslab ducting can significantly reduce noise transmission between floors. By being embedded within the concrete, the ductwork acts as a natural sound barrier, minimizing the transfer of noise from one floor to another. This feature is especially important in residential buildings where peace and quiet are highly valued.

  1. Enhanced Thermal Mass:

Concrete slabs have excellent thermal mass properties, meaning they can absorb, store, and release heat effectively. Inslab ducting takes advantage of this property by allowing the concrete to absorb and distribute heat evenly throughout the building. This results in more stable indoor temperatures and reduced HVAC energy consumption.

  1. Improved Energy Efficiency:

Inslab ducting systems benefit from the stable indoor temperatures provided by the building’s thermal mass. This stability reduces the HVAC system’s workload, leading to energy savings. Additionally, inslab ducts can be easily insulated to prevent heat loss or gain, further enhancing energy efficiency.

  1. Streamlined Installation and Maintenance:

Integrating ductwork during the construction phase streamlines the installation process. It eliminates the need for retrofitting ducts into existing structures, reducing labor costs and potential disruptions to occupants. Moreover, inslab ducting systems typically require less maintenance due to their protected placement within the building structure, resulting in long-term cost savings.

  1. Design Flexibility:

Inslab ducting offers greater design flexibility for architects and interior designers. With traditional ductwork hidden within the concrete, architects have more freedom to design aesthetically pleasing spaces without the constraints of visible HVAC components. This flexibility allows for innovative and visually appealing interior layouts in high-rise buildings.

 

In-slab ducting stands as a testament to the seamless integration of functionality and aesthetics in modern construction. As we conclude our discussion on this innovative HVAC solution, it is evident that in-slab ducting not only optimizes space but also enhances design flexibility. Its discreet design preserves architectural integrity while providing efficient air distribution. Let us embrace the evolution of construction methods, appreciating the harmony between form and function that in-slab ducting exemplifies. As we move forward, may this technology continue to shape comfortable and sustainable living environments for generations to come.

 

Product spotlight: FLIXS, Manufactured by FEAS ( Forest Energy and Air solutions) – Montreal, QC.

SRGDP-TL means Semi-Rigid-Galvanized-Double Wall with a thermo-laminated membrane. FLIXS is a uninsulated semi-rigid galvanized steel ventilation duct designed to be used in structural concrete slabs. This patent-pending product has a thermolaminated polymer membrane on its exterior surface to eliminate contact between steel and concrete thereby eliminating the development of corrosion.

SRGDP-TL is manufactured from a double strip of galvanized steel 0.005″ longitudinally profiled. The outer strip is contoured and allows the flexible structure of the duct to be created. The inner membrane creates a perfectly smooth surface and is simultaneously assembled into complex 7 facet joints. This seven-facet joint provides a perfect seal at the operating pressure shown in the table below while eliminating water leaks generated by condensation.

  • The interior surface of the SRGDP-TL is smoother than all ducts on the market.
  • The duct does not deform and thus keeps the circular surface even when it is bent at 90 degrees, limiting static loss.
  • No screws are required, eliminating debris buildup.
  • Sloping installation is possible allowing the elimination of condensation.
  • Conduit manufactured in one length without seal eliminating any possibility of water leakage.
  • Thermolaminated polymer membrane
