Aluminum Foil Self-Adhesive Insulation Pipe, Glass Wool Rock ,Outdoor Anti-Freezing(ID159MM/THK50MM). Good thermal insulation: the high density, sealed structure has a lower thermal conductivity than the raw material, which has the ability to stabilize the temperature and will not affect the inside of the water pipe when the weather changes. There are two thicknesses to choose from, 30mm/50mm, high and low temperature resistance, the shape will not be damaged or deformed because of the external high temperature, good thermal insulation, especially suitable for protecting outdoor water pipes from damage caused by freezing in winter or high temperature and hot sun in summer. Convenient installation: water pipe insulation layer is designed with a reserved gap, semi-open design, self-adhesive aluminum foil design, easy to cut and install, self-sealing design, easy to use. Wide range of applications: Suitable for hot and cold water pipes, air conditioning pipes, bathroom and solar water heaters, flue insulation, automobile pipes, external pipes and floor heating pipes. Foam Tubing Safety: Used for heat pipe or cold pipe to prevent condensation of cold pipe, flame retardant when burned by fire, insulating does not melt, produces low smoke, does not spread flame, and ensures safe use.
