Ducts & Duct Fittings
❓ Frequently Asked Questions
Galvanized ducts work well for most indoor commercial and residential projects, while stainless steel is preferred near coastal cities like Jeddah and Dammam because it resists moisture and salt-air corrosion better. Youmats supplies both in multiple thicknesses and diameters for reliable air-conditioning installations.
Common diameters range from 100 mm to 1600 mm, with straight runs, elbows, branches, and round or rectangular sections. Sizes are usually selected based on airflow requirements and heat-load calculations. Youmats can also support custom sizes for hospitals and large commercial complexes.
Yes. Insulation reduces heat gain, prevents condensation, and lowers airflow noise. In hot regions such as Riyadh and Dammam, moisture-resistant insulation with approved specifications is recommended. Thickness should match operating temperature, duct location, and local performance requirements.
Cost depends on network length, duct size, metal type, insulation level, and installation complexity inside the building. Custom lengths or diameters can be requested according to engineering drawings. Bulk contractor pricing is available, with sample inspection before execution on Riyadh or Jeddah projects.
Yes. Fire-rated fittings and access doors are available for fire-protection systems, with flame-resistant seals matched to project specifications. Compliance certificates, pressure testing, and leakage performance should be verified, especially for tunnels, parking areas, and high-rise buildings.
