POLYURETHANE BOARD
75%
Up to 75% lighter than steel ductwork.
20-30%
Faster installation time over steel.
The system is composed of CFC & HCFC free Polyurethane Foam Pre-insulated air duct panel and professional supporting accessories & tools.
By taking the rigid insulation foam as the core material and covered with embossed/smooth Aluminium foil on both sides, the PU Foam pre-insulated air duct panel obtains excellent performances of low vapour permeability, thermal resistance and good toughness properties, which is also environment-friendly.
ADVANTAGES OF FLOW DYNAMICS' POLYURETHANE BOARD
Flow Dynamics Polyurethane (PU) pre-insulated HVAC Cushion Head Boxes and Ductwork has a number of clear advantages.
✓ Lower heat conductivity, higher thermal efficiency
✓ Low-density, lightweight
✓ Foamed with CFC-free materials, environment protective
✓ Hermetic seal ensures little air leakage
✓ With aluminium foil reinforced on both sides, it is corrosion-protective, hygienic, and has a beautiful appearance.
✓ Foamed with a closed-cell structure, it's water-proof and sound-insulated.
✓ Easy making, rapid installing and convenient maintenance saves cost.
✓ No protruding flange on the connections, it can save a lot of building space.
