[Technical field to which the device belongs]

  The present invention fills the hollow layer with krypton gas and leaks the filled gas. In order to prevent and improve the durability performance of the seal in the peripheral part, the sealing material layer should be two or more layers, For the layer on the hollow layer side, a butyl polymer with a metal partition wall embedded is used, and it is exposed to the atmosphere. On the side to be filled, polysulfide rubber containing calcium carbonate, or in the molecule A glass member is used in combination with a polymer containing silicon as a sealing material. Relates to double glazing using laminated glass as

[0002]

[Prior art]

  As a glass material that is usually used to give crime prevention performance to windows of houses, etc. Use laminated glass. In addition, in order to improve the heat insulation performance, it is The thickness of the sky layer is set to 6 mm or more, and the double-walled glass filled with air is one Generally used. In addition, in order to have both crime prevention and heat insulation properties of the window, It has been practiced to use laminated glass as a member constituting the laminated glass.

[0003]   Double glazing having both crime prevention performance and heat insulation performance is an ordinary double glazing. Since the thickness increases even more, the groove width of the frame is usually set to fit in the frame of the window. Need to be even larger. Therefore, not only the groove width of the frame is increased, The overall thickness of the window that houses the frame should be large.

[0004]   Insulate only one sheet of glass into a normal window frame with a large thickness of double glazing If it becomes necessary to construct, increase the groove width to the range where double glazing can be inserted. It is fixed to the frame by using the auxiliary frame together. However, in this way Even if the lath is installed, in the form of opening and closing the window by pulling the frame When the thickness of the double glazing exceeds 12.5 mm, the If the auxiliary frame comes into contact with the latch or screen to prevent the door from opening and closing. There are many cases.

[0005]   Therefore, in the double glazing in which the hollow layer is filled with air, the glass member constituting The one that uses laminated glass for a general window that fits one sheet of glass Cannot be used as a frame.

[0006]

[Problems to be solved by the device]

  In order to have both the crime prevention performance and the heat insulation performance of the window, all the double glazing that can be housed in the frame The greater the body thickness, the more advantageous it becomes. However, the frame of the window for the house is a single plate The specifications for accommodating the lath are general, and it is assumed that an auxiliary frame with an enlarged groove width is also used. However, the width of the groove that holds the glass is limited.

[0007]   Therefore, the smaller the overall thickness of the double glazing, the more room it will fit in the frame. However, when the double glazing with the performance of the present invention is applied to a general window, it is possible. In, while limiting the overall thickness of the double glazing to a size that can be fixed to a general window frame, It must have sufficient crime prevention performance and heat insulation performance.

[0008]

[Means for Solving the Problems]

  Even if the present invention is designed for one sheet of glass, the frame to be constructed is In order to enable the construction of double glazing that has both criminal performance and heat insulation performance, The maximum body thickness is 12.5 mm or less.

[0009]   In order to limit the total thickness of the double glazing to 12.5 mm or less, The thickness should be 2.3 mm or less. However, multi-layered glass with a small hollow layer thickness In order to provide a practically sufficient heat insulation performance, the hollow layer has a higher heat insulation performance than air. Filling with krypton gas at 80% or more by volume. Suppresses conduction heat transfer. However, in order to suppress conduction heat transfer sufficiently, It is desirable that the layer thickness is 1 millimeter or more.

[0010]   In order to further improve the heat insulation performance, the number of flat glass that composes double glazing At least one sheet has a low emissivity film with a vertical emissivity value of 0.25 or less on the surface of the hollow layer. The radiant heat transfer is suppressed by arranging a sheet glass coated on the.

[0011]   In addition, the gas filled in the hollow layer of the double glazing leaks during a long period of use. To prevent this, the sealing material in the peripheral part of the double-glazed glass should be a multilayer with two or more layers, and the hollow layer side The sealing material is a rubber-based butyl-based heavy-duty material with a metal partition wall that prevents gas migration. Polysulfide rubber containing calcium carbonate in the outer layer Alternatively, a polymer containing silicon in the molecule is arranged.

[0012]   In order to limit the total thickness to 12.5 mm or less, make up the double glazing. The thickness of each glass is the raw glass that is a member of the laminated glass, or a single plate Each of the glasses has a thickness of 4.0 mm or less. However, to ensure strength 2.4 mm or more is desirable.

[0013]   The thickness of the interlayer film of the laminated glass used in this invention is Since it is limited, it should be 1.6 mm or less. However, the strength of laminated glass 0.3 mm or more is desirable to secure

[0014]   The double glazing of the present invention, which has both crime prevention and heat insulation properties, allows ultraviolet rays to enter through the window. It can also be used in stores that do not like to store. Practically hinders the entry of ultraviolet rays In order to suppress it to the range where there is no The laminated glass has a light transmittance of 2% at a wavelength of 380 mm. Use the following.

[0015]   The term double-glazing, sealing, and hollow layer, which are the terms of the present invention, are Japanese Industrial Standard R3209, Direct emissivity is R3106 of the same standard, and laminated glass and interlayer are R3205 of the same standard. It has the same meaning as that used.
