Home / Jackets and Blankets / Insulator Jackets


Custom Designed, Insulated Jackets offer an elegant, efficient way to apply removable insulation onto specific shapes. Insulation Jackets provide convenient access, to pipes, valves, instrumentation or any device that has to be inspected removed or visually monitored. HTS/Amptek® designs can offer increased efficiency when installed over Heating Tapes, Band or Strip Heaters. Shaped Jackets are fabricated into a preformed shape that will easily fit the object. This is opposed to flat insulation pieces which fold up and "pucker" resisting closure and leaving air-gaps.

Jacket sizes:
Small Insulating Jackets may be constructed to fit ¾ inch diameter tubing and fittings. Large Heating Jackets are limited by weight, typically 50lbs (23kg), but may be constructed in multiples to fit large surfaces.

All Jackets are pre-formed to the 3D shape and double stitched for durability. First, the inner liner is designed to suit the thermal characteristics of the application. Next, the insulation layers are placed over the liner with outer fabrics to enclose the assembly. The materials of construction depend upon the temperature and environment of use. In the freeze protection temperature range, Closed Cell Foam with Polyester Vinyl will provide insulation without absorbing moisture. For heated applications up to 500° F choices can include materials such as Teflon® and Silicone, which provide durability and some moisture protection. Moderate and High temperature Insulation Jackets, are constructed of safe fiberglass-based fabrics with soft, Fiberglass Silica or Ceramic insulations.

Temperature Capability:
Typical Construction methods can offer Fiberglass to 900°F (482°C), or AMOX™ to 1400°F (760°C). Contact HTS/Amptek® to discuss special, Ceramic based, fabrics and insulation that can offer heat ranges to 1832°F (1000°C) and higher.

Cutouts and Penetrations:
Cut outs and slits for supports, ports and other hardware are typical of most applications. HTS/Amptek® designs preformed Jacket configurations with gusseted holes, slits and seams to provide great fit and easy install and removal. Additional flaps and straps cover the exposed seams.

Most common Closures are Velcro® flap and D ring strap or lacing eye closure methods, however quicker and cleaner methods include convenient snaps or Delrin® Clips.
