Commercial HVAC Ductwork
Flexible and insulated ducts for commercial air distribution — office buildings, retail spaces, hotels, restaurants, and multi-story ventilation systems. Manufactured in Houston, TX and Dongyang, China.
Why commercial buildings choose flexible ductwork
Commercial HVAC systems need ductwork that adapts to complex ceiling layouts, tight plenum spaces, and evolving tenant configurations. Flexible ducts install faster, route around obstacles, and reduce noise — without sacrificing airflow performance.
Flexible duct installs 3-5x faster than rigid sheet metal. Critical for tenant build-outs, renovations, and retrofit projects where downtime means lost revenue. No welding, no sheet metal shop — cut, connect, secure.
UL 181 Class 1 certified for flame spread and smoke development. Meets all US building codes for commercial HVAC installations. Insurance-ready documentation for every project.
Flexible duct naturally attenuates HVAC noise better than rigid metal duct. Combined with our soundproof insulated ducts, achieve NC-30 or lower in offices, hotel rooms, and quiet retail environments.
Ductwork for every commercial environment
Office Buildings & Tenant Build-Outs
Multi-zone HVAC systems in office spaces need flexible routing from VAV boxes to ceiling diffusers. When tenants change, flexible duct re-routes without demolishing hard duct runs. Our R6 and R8 insulated flex ducts prevent condensation in above-ceiling plenums and maintain supply air temperature to each zone.
Retail Spaces & Shopping Centers
Retail HVAC must handle high occupancy loads, kitchen exhaust from food courts, and frequent layout changes as stores reconfigure. Aluminum flex ducts provide the flexibility to route around sprinkler lines, electrical conduit, and structural beams in tight ceiling spaces. Large-diameter options handle the high CFM demands of open-plan retail environments.
Hotels & Hospitality
Guest comfort depends on quiet, consistent air distribution to every room. Our soundproof insulated ducts reduce HVAC noise to below NC-30 — essential for guest satisfaction. Insulated flex duct also prevents condensation dripping onto ceiling tiles, a common complaint in humid climates. Each room gets individually controlled supply air via flexible duct branches from the corridor main.
Restaurants & Commercial Kitchens
Restaurant HVAC handles kitchen exhaust make-up air, dining room comfort cooling, and bathroom exhaust — all in a compact footprint. Semi-rigid aluminum ducts maintain shape in tight ceiling cavities above kitchens, while PVC steel wire ducts handle grease-laden exhaust routing. Our ducts are designed to work alongside kitchen hood exhaust systems without cross-contamination.
Multi-Story & High-Rise Buildings
Vertical air distribution in multi-story buildings requires flexible duct connections between rigid risers and floor-level distribution. Our insulated flex ducts absorb building movement, floor settling, and thermal expansion that would crack rigid connections. Available in diameters up to 24 inches for high-rise main distribution branches.
Built for commercial scale
Whether it's a single office renovation or a 50-story mixed-use tower, our dual-facility production model delivers the volume, consistency, and lead times commercial projects demand.
