PURPOSE:To exhibit cloudproofing performance over a long period of time at a low cost without maintaining high airtightness on a middle layer by applying a cloudproofing coating on the inside surfaces mutually opposed of a double window made from synthetic resin. CONSTITUTION:A double window is constituted so that two pieces of synthetic resin plate on which hard coating 4 is executed on one face and cloudproofing coating 3 is applied on the another face are opposed so as to face ech other with the cloudproofed faces and with a middle layer 6 between, and both plates are fixed with airtight seal agent 2 so as to make the middle layer to be an airtight part. The cloudproofing coating is constituted of coating of spreading and drying of a hydrophilic high polymer film, a liquid film or non-polymer coating film, a crosslinked film of hydrogel polymer, a crosslinked film of a composite containing organic silicon polymer, a crosslinked film of a melamine resin base composite, a coating film containing fluoropolymer or a plasma polymerized film, or the like. |
