Shand & Jurs insulation jackets provide heat retention for equipment in cold weather environments. Our Insulation Jackets are constructed of a silicone impregnated woven glass cloth lining with a 1 inch thick 6 lb. density fiber glass insulating material. Through cover quilting pins, provide support to keep the insulation from shifting inside while providing dimensional stability ensuring uniform heat retention. Velcro cinch belts and straps with D-rings allow easy install/removal and maintenance access to tube banks when necessary without removing the entire jacket.
