HVAC DUCT INSULATION AND METAL CLADDING ENGINEERING
Zero condensation, acoustic sound absorption and heavy-duty metal cladding for HVAC air distribution, smoke extraction and outdoor ductwork.
Thermal Efficiency, Condensation Control and Acoustic Comfort in Industrial Ductwork
In modern industrial plants, factories, data centers and commercial buildings, heating, ventilation and air conditioning (HVAC) ducts provide continuous distribution of conditioned supply air, hygienic process air and emergency smoke extraction. However, uninsulated or poorly installed ductwork leads to severe surface condensation (sweating), uncontrolled energy losses, fan roar transmission and breach of fire compartments.
Deta Industry provides comprehensive duct insulation solutions strictly adhering to VDI 2055, DIN EN ISO 12241 and EN 1366-1 engineering standards for rectangular and spiral circular ducts. We ensure dew point security using closed-cell elastomeric rubber foam (μ ≥ 7000) on cold supply air ducts, while applying aluminum foil-faced rockwool blankets on heated lines and EI60 - EI120 certified fire protection on smoke extraction systems.
For outdoor ductwork located on rooftops or building facades exposed to severe weather, UV radiation and mechanical impacts, we install precision-formed 0.80 mm - 1.00 mm beaded aluminum or galvanized metal cladding (jacketing) to safeguard thermal integrity for decades.
HVAC and Duct Insulation Solutions Scope

4 Core Engineering Pillars of Duct Insulation
Core pillars delivering high energy savings, fire safety and acoustic comfort across duct networks:
Zero Condensation and Dew Point Control
Closed-cell elastomeric rubber sheets (μ ≥ 7000) keep duct surface temperature well above ambient dew point, completely eliminating moisture dripping and corrosion.
EI60 - EI120 Fire and Smoke Safety
Certified high-density rockwool barriers and intumescent sealants compliant with EN 1366-1 and BS 476 prevent flame and smoke propagation across building fire compartments.
Outdoor UV and Weather Metal Cladding
Rooftop and external ducts are armored with beaded, lock-seamed aluminum or galvanized sheets protecting insulation against storm winds, hail and UV degradation.
Acoustic Comfort and Vibration Attenuation
High-velocity air turbulence and fan roar are attenuated via internal black glass-tissue faced acoustic duct liners and flexible vibration isolation expansion joints.
