PURPOSE:To apply a weather-resistant seamless sheathing, by applying an elastic coating on one surface of a core material that uses as a base a plastic film, and an adhesive sheet on the other surface, and peeling off a release paper from the adhesive sheet. CONSTITUTION:The circumference of a water delivering pipe 1 is enclosed with an insulating material 2 having a thickness of 20mm., and the adhesive sheet 3 that is flexible, weather resistant, moisture impermeable and alkali-resistant is wound around and stuck to the insulating material 2. A saturated polyester film 4 having a thickness of 100mum is used as a core material, a coating 5 of a silicone type material having a thickness of 300mum that has weathering property, etc. is applied on the surface of the film 4, and a fire retardant adhesive layer 6 of a butyl rubber type material having a thickness of 500mum is provided on the undersurface of the film 4. When the adhesive sheet 3 is wound around and stuck to the insulating material 2, the release paper 7 is peeled off and the winding is carried out. |
