Protects outdoor HVAC ducts and copper lines from sun, UV exposure, and low temperatures so systems stay insulated and functional in changing weather. Multilayer insulation construction: Outer layer: durable 600D Oxford fabric provides strong water resistance and everyday abrasion protection. Inner layers: pearl cotton and aluminum foil combine to reduce heat transfer and help maintain thermal performance. Weather and UVresistant materials prevent degradation from sunlight, rain, and cold, extending the service life of duct and pipe insulation. Practical protection for both copper pipe and duct insulation: addresses common outdoor insulation needs by shielding vulnerable components from environmental damage. Easy to install and reuse: engineered touch fasteners allow quick application and removal without tools, supporting repeated use with minimal effort. Use scenarios: Rooftop or exterior HVAC ductwork that requires ongoing protection from sunlight, rain, and temperature swings. Outdoor heat pump or airconditioning copper refrigerant lines needing abrasion, UV, and weatherresistant insulation covers. Exposed ducts or pipes in unconditioned outdoor enclosures or service areas where water resistance and thermal retention are important. Key attributes at a glance: Function: outdoor protection and thermal insulation for ducts and copper pipes Materials: 600D Oxford fabric (outer), pearl cotton and aluminum foil (inner) Performance: waterresistant outer layer, thermal insulation from inner layers, UV and weather resistance Installation: touch fasteners for simple, repeatable on/off use This product is designed to safeguard outdoor HVAC ducts and copper piping from environmental wear while providing reliable, reusable insulation and easy maintenance.
