Flexible Ducts

Flexible ducts are easier to install in tight ceilings and reduce vibration, making them useful for branches in homes and mid-size units. Rigid ducts last longer and handle higher steady pressure better, so they suit long runs or high-pressure networks. Hybrid designs often balance cost, airflow, and durability.

Yes. Uninsulated flexible ducts can develop water droplets when cold air meets humid summer conditions, especially in Riyadh and Jeddah. Choose thermally insulated flexible ducts or add suitable adhesive insulation, and seal joints tightly to prevent air leakage and condensation.

Size depends on required airflow, run length, and bends. Common residential and light commercial applications often use 15 to 30 cm diameters. Avoid undersizing, as it lowers cooling performance and increases pressure loss. For larger projects, an HVAC engineer should select the size based on the system load.

They should not leak if the material is sound and installation follows best practice. Use durable-wall flexible ducts, correct clamps, and avoid excessive length or sharp bends. Youmats offers insulated options that reduce air loss and include clear installation guidance for contractors to maintain consistent airflow.

Price varies by diameter, insulation type, wall thickness, and roll length. Saudi market prices rise with larger sizes and thermal insulation.
