INSULATING FLEXIBLE DUCTING CORE

 
 

The insulating of the flexible ducting core produce by the LS2000 is a simple process and the technique has been virtually unchanged for 30 years. The process involves wrapping the finished core material with a fiberglass insulation blanket and then sleeving the wrapped core with a continuous vapor barrier tube.The following diagram is a typical Flex Insulation Table. Variations of this insulation table will occur depending on a manufacturers preferences.

This assembly has a frame to support a rollof blanket fiberglass insulation and a Core Feedercradle that the core from the LS-2000 lays in as it is insulated. The sleeving process takes place at the Forming Head or mandrelwhich corresponds to the diameter of the desired flexible ducting core to be insulated with the corresponding insulation thickness.

The process is a semi manual procedure with requirement of two men. The insulating procedure goes as followings. The first person stands at the forming bed and wraps the blanket insulation around the flexible ducting core from the core feederand stuffs the wrapped flexible ducting core into the forming head. The second person slides the vapor barrier tube over the forming head until the complete vapor barrier is on the outside forming head. The second person then pulls the wrapped core with insulation through the inside of the forming headas well as the vapor barrier from the outside of the forming head at the same time. The first person continues to help wrap the flexible ducting core with insulation and aids in stuffing it into the forming headas it is being pulled by the second person through the forming head. This automatically sleeves the flexible ducting core with insulation and vapor barrier.

The length of the insulated cored can vary depending on the desired length required. Typical lengths are from 20 to 30 feet in length. The insulated product is now ready to be boxed or bagged.
