High quality 50mm polyester insulation insulated ducting for HVAC system


Insulated Flexible Aluminum Foil Duct:( DEC-IA)(with seamless outer jacket)

The inner flexible duct is aluminum foil/polyester covered with 25mm 16kg/m³ fiber glass wool and outer jacket made of aluminum foil and polyester film. The outer jacket is seamless.

The insulated aluminum flex duct consists of an aluminum laminate inner duct, thermally insulated with a glass wool layer and provided with an aluminum laminated outer jacket.

The thermal insulation is suitable for preventing condensation and minimizing heat loss and loss of cold.

All the flexible duct shall be installed in a fully extruded position and bends made with adequate radius.

The maximum allowable sag, between any two adjacent suspension points, should not exceed 50 mm per meter.

The distance between any two adjacent suspension points may vary from 1.50 to 3.00 meter, depending upon the type of flexible duct in use.

Flexible ducts mounted above suspended ceiling should always be independently supported.

All bends should be made as large as possible and should have a radius of not less than the diameter of the duct in use. Double bends should be avoided, however if un-avoidable, ensure that each radius is not less than R = 2 x D.

Ideally the hanging straps should supports the flexible duct with a minimum of half the circumference surface in contact, and without reducing the effective inside diameter of the duct. It is also recommended that the minimum width of material to be used for the hanging straps should be at least 25 mm.

Extra care should be taken when making connection to fixed conventional ducts, and ensure that they do not become too stressed. An additional support is recommended to overcome the potential problem.

Light railing is a good alternative hanging support when using long length of flexible duct.
