Description

The present invention relates to a simple heat insulating window having a high heat insulating property and having a heat insulating portion that can be easily attached and detached and can be used repeatedly.

In recent years, from the viewpoint of energy saving, attempts have been made to achieve a high heat insulation effect from the outside world and to increase the efficiency of air conditioning to the limit. In order to increase the efficiency of air conditioning, it is necessary to perform independent air conditioning for each room. For this purpose, various wall materials having high heat insulation properties have been proposed.
In addition, lighting is extremely important when considering the living environment of a building. In the current building, it is common to install a glass window in the daylighting section, but it is difficult to exert a high heat insulating effect compared to wall materials and the like. According to the “Energy Conservation Technology Strategy Report” (June 12, 2002, Ministry of Economy, Trade and Industry), it is said that 45% of all energy consumed is lost through openings such as windows.

As glass with high heat insulation, what is called pair glass is proposed (for example, patent document 1 etc.). Paired glass is a glass that has a gap between two glass plates and is evacuated or blown with an inert gas such as argon. To do. However, there is a problem that the pair glass is tens of thousands to hundreds of thousands of yen / m ² and is more expensive than normal glass. Moreover, in order to replace the already installed single plate glass, a frame material replacement work is required, which is difficult to realize in an apartment house, a rental house, and the like.

In contrast, so-called “heat insulation sheets”, “condensation prevention sheets” and the like are commercially available. These sheets are intended to easily enhance the heat insulation of the opening by sticking to the surface of the single plate glass with an adhesive or the like.
However, none of the conventional “heat-insulating sheets” and “condensation prevention sheets” can exhibit a heat insulating property of about 3.5, which is comparable to that of paired glass, and the effects thereof are only limited. In addition, due to the construction method of sticking with an adhesive or the like, it is difficult to reuse what has been peeled off once, and there is a problem that it is necessary to peel it off in the summer and re-attach a new one in the winter. Further, when left for a long time, there is also a problem that an adhesive residue may be generated on the glass side when peeled.

Japanese Patent Application Laid-Open No. 2003-026453

In addition to the above-mentioned pair glass, heat insulating sheet, dew condensation preventing sheet, etc., it is conceivable to use a daylighting heat insulating material in order to enhance the heat insulating property while maintaining the daylighting property. The present inventors have already shown that a daylighting heat insulating material having a structure in which a plurality of resin films face each other with an air layer having a thickness of 100 μm to 3 mm interposed therebetween can exhibit high heat insulating properties even though it is extremely lightweight. (Japanese Patent Laid-Open No. 2006-291608).
As an installation aspect of such a daylighting heat insulating material, for example, an aspect in which a daylighting heat insulating material is attached to the surface of a single plate glass using an adhesive sheet coated with an adhesive on one surface of the face material, like a heat insulating sheet or the like, a double-sided tape The aspect which fixes only the edge part of a daylighting heat insulating material using tapes or adhesives, etc., and a lighting heat insulating material are physically fixed to the surface of a single plate glass using fixing members, such as a nail, a screw, and L-shaped metal fittings In addition to the mode (shown in FIG. 7), as shown in FIG. 8, as shown in FIG. The aspect fixed to the outside (FIG.8 (b)) is mentioned. However, even when fixing to the frame of the window in this way, once the lighting heat insulating material is fixed, it cannot be easily removed, and there is a problem that it is difficult to use according to the season and purpose.

An object of this invention is to provide the simple heat insulation window which has a heat insulation part which has high heat insulation and is easy to attach or detach and can be used repeatedly.

The present invention is a simple heat insulating window comprising a window glass portion and a daylighting heat insulating material, wherein the daylighting heat insulating material has a structure in which a plurality of base films are opposed to each other across a gas layer having a thickness of 100 μm to 3 mm. The window glass part and the daylighting heat insulating material are simple heat insulating windows fitted with an air tight structure frame.
The present invention is described in detail below.

Hereinafter, the present invention will be described with reference to embodiments.
The simple heat insulation window of this invention consists of a window glass part and a lighting insulation material.
The window glass part is not particularly limited, and any window glass part can be used as long as it is used for an opening of a normal building. For the purposes of the present invention, single plate glass is suitable, but paired glass or the like may be used when particularly high heat insulation is required.

The daylighting insulating material has a structure in which a plurality of base film films are opposed to each other with a predetermined gas layer interposed therebetween.
The daylighting heat insulating material may have a structure in which a gas layer is sandwiched between two base film, but as long as the visible light transmittance described later is satisfied, a plurality of base films of three or more A structure in which a gas layer is sandwiched between them is preferable. The lighting heat insulating material having a plurality of gas layers can exhibit a high heat insulating effect. Also, since the temperature difference between the base films is small and the occurrence of condensation is suppressed, when attaching frame materials used in edge processing of face materials such as glass and heat insulating materials used in conventional openings The amount of desiccant needed can be reduced and may not be used.

The present inventors have found that a particularly high heat insulating effect can be exhibited when the thickness of the gas layer is in a specific range. The heat transmissivity is related to the thickness of the gas layer, the total thickness, and the number of layers. When the thickness of the gas layer is 0 and the number of layers is 1, it is equal to the thermal permeability of the base film itself, and when the gas layer is sufficiently thick, it approaches the thermal penetration rate (theoretical value) of the gas itself. With the increase in the thermal conductivity, the heat transmissivity is small, that is, the heat insulation is increased. Furthermore, if the gas layer spacing is such that convection does not occur under a certain total thickness, if the total thickness of the gas layer in the total thickness is more than a certain value, Stefan Boltzmann's It was found that the heat transmissivity shows a minimum value due to the effect of reducing radiant heat based on the law. That is, in the daylighting heat insulating material of the present invention, when the lower limit of the thickness of each gas layer is 100 μm, the upper limit is 3 mm, and the number of layers is 3 to 20, a particularly high heat insulating effect can be obtained. understood. The more preferable lower limit of the thickness of each gas layer is 200 μm, the more preferable upper limit is 2 mm, and the more preferable number of layers is 4 to 10 layers.

The gas layer may seal the periphery. With such a structure, internal condensation can be prevented. The gas layer may communicate with another gas layer through the base film, or may have a structure in which gas can move between the gas layers. That is, a nonwoven fabric or a film with a hole of about 5 mmφ can be used as a substrate.

The gas layer is preferably divided into a plurality of cells. By dividing the gas layer into a plurality of cells, the strength of the entire daylighting insulating material of the present invention can be increased. In the present invention, the resin spacer plays the role of this cell division. Preferred lower limit is 4 cm ² in size for each cell of the gas layer, the upper limit thereof is preferably 1800 cm ^2. When the size of each cell in the gas layer is less than 4 cm ² , the visible light transmittance of the obtained lighting heat insulating material may be inferior or the heat insulating property may be lowered. When the size of each cell in the gas layer exceeds 1800 cm ² , the strength of the obtained daylighting heat insulating material may be inferior. A more preferable lower limit of the size of each cell of the gas layer is 25 cm ² , and a more preferable upper limit is 600 cm ² .

It does not specifically limit as gas which comprises the said gas layer, For example, air, a carbon dioxide, etc. are mentioned.
Further, as the gas, a gas having a fragrance effect, a gas colored with smoke or the like can be filled. By filling such a gas, various functions can be imparted to the daylighting heat insulating material of the present invention.

A liquid for imparting design properties may be inserted into the gas layer.
Although it does not specifically limit as said liquid, For example, colored water etc. are preferable. By using colored water or the like, designability can be imparted to the daylighting heat insulating material of the present invention.
When a gas other than the liquid or air is inserted into the gas layer, it is necessary to sufficiently seal and seal the gas layer into which the liquid is inserted.

When the liquid is inserted into the gas layer, the liquid may be inserted so as to fill the entire space of the gas layer, and a part of the gas layer, for example, a part of the cell in the gas layer Can be inserted only.

A solid for imparting design properties may be inserted into the gas layer.
The solid is not particularly limited, and examples thereof include materials, pictures, and books used for displays such as colored beads, dolls, stuffed animals, cloth / clothing, paper malls, dried flowers, and fresh flowers with a humidity control agent. Examples thereof include materials that improve the interior properties of living spaces such as light emitters such as lights and lamps.

When the solid is inserted into the gas layer, the solid may be inserted so as to fill the entire space of the gas layer, and a part of the gas layer, for example, a part of the cell in the gas layer Can be inserted only. When the solid is inserted into the gas layer, a part of the solid may be fixed by a method using a wire, piano wire, glass fiber, or the like, or a method of sticking.

A combination of the liquid and solid may be inserted into the gas layer, and the solid may be suspended in the liquid or submerged in the liquid in the gas layer.

When the liquid or solid is inserted into the gas layer, the base film preferably has a strength capable of withstanding its own weight.

Although it does not specifically limit as a base film which comprises the said lighting insulation material, Since it is lightweight, a resin film is suitable.
The resin film is not particularly limited as long as it is excellent in transparency. For example, it is made of polyethylene terephthalate, polybutylene terephthalate, polycarbonate, polyethylene, acrylic, vinyl chloride, fluorine-containing resin, polyvinyl alcohol, cellulose triacetate, or the like. Things.
Of these, polycarbonate and vinyl chloride are preferable because they are self-extinguishing and have good compatibility as a building material. Moreover, it is preferable to use the resin film which gave the hard coat for the purpose of improving the scratch resistance of the resin film. Such a hard coat is not particularly limited, and examples thereof include those made of an acrylic resin. As the resin film to which such a hard coat is applied, for example, a resin film having a two-layer structure in which an acrylic resin layer is formed on the surface of a polycarbonate film or the like can be suitably used. Furthermore, when laminating a resin film on another base film, for example, polybutylene terephthalate can be suitably used.

As said base film, the film for the purpose of various functions, such as the designable film for the purpose of designability provision, the optical adjustment film for the purpose of visibility adjustment, may be sufficient as part or all of the said base film. . Further, depending on the purpose, an advertising logo, a partially pasted seal, or the like may be attached to the base film.

Although it does not specifically limit as thickness of the said base film, A preferable minimum is 10 micrometers and a preferable upper limit is 300 micrometers. When the thickness of the base film is less than 10 μm, the strength of the obtained daylighting heat insulating material may be inferior. When the thickness of the base film exceeds 300 μm, the daylighting heat insulating material may become thicker than necessary to obtain the same heat insulating effect. The minimum with more preferable thickness of the said base film is 20 micrometers, and a more preferable upper limit is 250 micrometers. In the daylighting heat insulating material of the present invention, when the strength of only the surface is required, a thick base film may be used only for the surface layer.

It is preferable that the said lighting insulation material has a spacer between base film. The spacer is used for maintaining the gas layer (maintaining the base film interval), sealing the periphery of the gas layer, dividing the gas layer, and the like.

Although it does not specifically limit as said spacer, In order to ensure the visible light transmittance | permeability of a lighting heat insulating material, it is preferable that it is transparent, and in order not to impair the heat insulation performance of a lighting heat insulating material, it is a thing with high heat insulation. Is preferred. Although it does not specifically limit as such a spacer, For example, a hollow body (a foam is included), FRP, the acrylic resin which has self-adhesiveness, etc. are suitable.

The shape of the spacer is not particularly limited, and may be particulate, linear, or the like. Moreover, you may provide designability to the obtained lighting heat insulating material with the shape of the said spacer. In addition, when there are a plurality of the gas layers, the spacers defining each gas layer may have the same shape or different shapes. For example, the spacers defining the adjacent gas layers may be orthogonal, and the spacers may have a lattice shape as a whole.

As for the said lighting insulation material, the minimum with the preferable preferable whole thickness is 3 mm, and a preferable upper limit is 5 mm. If the total thickness of the daylighting heat insulating material is less than 3 mm, sufficient heat insulating properties may not be exhibited. If the total thickness of the daylighting insulation exceeds 5 mm, it may not fit in the rail when applied to a general sliding window.
The simple heat insulating window of the present invention is characterized in that the daylighting heat insulating material can be fixed to the existing glass window without providing a separate rail or damaging the wall surface of the house.

In the daylighting insulator, the preferable lower limit of the visible light transmittance is 20%. If the visible light transmittance is less than 20%, sufficient lighting may not be obtained. The more preferable lower limit of the visible light transmittance of the daylighting insulating material is 30%, and the more preferable lower limit is 40%.

In the simple heat insulation window of this invention, the said window glass part and the lighting insulation material are fitted by the air tight structure frame.
In the present specification, the air tight structure frame is a frame material having a fitting part of a male part and a female part, and particularly means that the fitting part has an airtight structure. Furthermore, the air tight structure frame may have one male part and one female part fitting part, or may have a plurality in parallel.

One of the fitting portions of the air tight structure frame is fixed in advance around the daylighting heat insulating material by a fixing member such as a double-sided tape or a fixing member such as a fastener. By fixing the air tight structure frame to the daylighting heat insulating material in advance, the workability is improved, and at the same time, the face material of the daylighting heat insulating material is less likely to slip off against repeated impacts such as opening and closing of windows. However, when the daylighting heat insulating material is frequently removed according to cleaning or seasonal changes, the removal work can be easily performed without fixing the air tight structure frame and the daylighting heat insulating material. At this time, the male part may be fixed to the daylighting heat insulating material, and the female part may be fixed to the daylighting heat insulating material.
On the other hand, in the air tight structure frame, for example, a mating portion to be paired is fixed to the window glass portion by a fixing member such as a double-sided tape or a fixing member such as a fastener. At this time, the installation part of the fitting part in the window glass part is not particularly limited, and can be appropriately selected depending on the heat insulation and the functionality of the window glass part. For example, the edge of the opening glass surface of the glass window , Sash frame, picture frame and the like.
Next, the daylight insulating heat insulating material is applied so that the fitting portion fixed to the daylighting insulating material is fitted into a mating fitting member fixed to the window glass portion.

When the air tight structure frame is installed at the edge of the opening glass surface of the glass window, the window can be opened and closed with the daylighting heat insulating material applied even if it is a sliding window. In addition, as will be described later, for example, a fastener or clip (FIGS. 10A and 10B) in which one side can be inserted into the airtight structure frame and the other side can be inserted and fixed to the glazing channel portion. Or a fastener or clip (FIG. 10 (FIG. 10) that can be fixed by covering one side from the outside of the airtight structure frame after fitting, and inserting and fixing the other side to the glazing channel portion. By using a) shown in c), it is possible to more easily construct the daylighting heat insulating material.
The glazing channel portion is a portion made of a rubber material around the glass surface, and is a portion made of a material for fixing the glass to the sash frame.

When the air tight structure frame is installed in a sash frame or a frame, the window cannot be opened and closed with the daylighting heat insulating material being applied if it is a sliding window. Therefore, such an installation method is suitable in the case of a FIX window for lighting without an opening / closing function. However, since the air tight structure frame is used for fitting, the lighting heat insulating material can be easily attached and detached as needed.
Furthermore, when the air tight structure frame is installed on the sash frame or the frame, the air layer between the sash frame and the sash frame and the frame is also insulated, so that the sash frame is not only prevented from dew condensation but also has a higher thermal insulation. It can be demonstrated.

The material of the air tight structure frame is not particularly limited, and examples thereof include metals such as aluminum and stainless steel, wood, bamboo, plastic, crosslinked or uncrosslinked rubber, and FRP. Especially, since it is excellent in heat insulation and durability, a plastic is suitable.

The plastic is not particularly limited, and examples thereof include olefins such as vinyl chloride resin, acrylic resin, polycarbonate resin, and polypropylene (PP), polystyrene resin, ASA resin, and AES resin.
The plastic may be transparent, translucent or opaque. When the plastic is transparent, for example, the design properties can be improved by taking advantage of the transparency of the daylighting heat insulating material.

The plastic may be a hard material, a semi-hard material, or a soft material. When the plastic is a hard material or a semi-hard material, the plastic is a so-called elastomer.
When the plastic is a hard material, for example, the air tight structure frame can be folded and processed by scratching one side with a cutter or the like. Moreover, when removing the said daylighting heat insulating material in the state which fitted the said air tight structure frame, since the said plastic is a hard material, the rigidity as a face material of the said daylighting heat insulating material will improve and handling property will improve. .

When the plastic is a semi-rigid material or a soft material, the air tight structure frame can be easily cut with, for example, cutting scissors and the handling property is improved. Moreover, the said lighting insulation material can also be constructed in the curved part, such as a part with R at a corner | angular part, a circular window, or a curved surface part, and it is easy to perform fitting on / off.
In addition, an example of the fitting part at the time of using a soft material for an air tight structure frame is typically shown in FIG.

Although there is no limitation in particular about the fixing method of the air tight structure frame to a glass surface, Since it is dry and simple, the method of using a double-sided tape is mentioned, for example.
However, when a double-sided tape is used, chemical components such as a plasticizer blended in the adhesive or paste may induce mold and the like, which may reduce durability. Furthermore, when using double-sided tape, the air tight structure frame can be detached, but it is necessary to spray the adhesive residue after removal, or the design is reduced by the glue part being visible from the outside, Since the fixing of the air tight structure frame itself depends on the durability of the adhesive and the glue with respect to the adhesive strength and coloring, the durability as a simple heat insulating window may be lowered.

As a method for fixing the air tight structure frame to the glass surface, in addition to the method using the double-sided tape described above, for example, a method using a fastener or a clip can be mentioned.
As the clasp or clip, for example, a clasp or clip that can be inserted on one side into an airtight structure frame and can be inserted and fixed on the glazing channel portion (FIGS. 10A and 10B). Or a fastener or clip (FIG. 10 (FIG. 10) that can be fixed by covering one side from the outside of the airtight structure frame after fitting, and inserting and fixing the other side to the glazing channel portion. c)) and the like. By using these fasteners or clips, it is possible to easily construct the daylighting heat insulating material, and since the fasteners or clips can be removed from the glazing channel portion first, the daylighting heat insulating material is more easily removed. be able to. In addition, it is possible to more easily construct the daylighting heat insulating material by fixing the clasp or clip to the daylighting heat insulating material first, and inserting the clasp or clip into the glazing channel when using the daylighting heat insulating material. it can.

The clasp or clip is not particularly limited, and examples thereof include a clasp or clip provided with an insertion portion into an air tight structure frame fixed to a daylighting heat insulating material and an insertion portion into a glazing channel portion.
As such a fastener or clip, for example, a fastener having the same insertion direction into the airtight structure frame and the insertion direction into the glazing channel portion and having a U-shaped or deformed U-shaped cross section. Or the clip (shown in FIG. 10A), the insertion direction to the air tight structure frame and the insertion direction to the glazing channel portion are opposite, and the cross section is S-shaped, modified S-shaped or modified L-shaped And a fastener or clip having an L-shaped cross section in which the insertion direction into the airtight structure frame and the insertion direction into the glazing channel portion are perpendicular to each other. Further, in order to firmly fix the fastener or clip to the air tight structure frame, there is a fastener or clip having a slit-like cut or the like in which one end of the metal fitting can be inserted inside the air tight structure frame (FIG. 10 (b). ) Can also be used.

Examples of the clasp or clip further include a clasp or clip including a frame fixing portion that covers and fixes the airtight structure frame from the outside and an insertion portion to the glazing channel portion.
As such a fastener or clip, for example, a fastener or clip (shown in FIG. 10C) including a frame fixing portion having an L-shaped cross section and an insertion portion having a linear cross section. . Note that the L-shaped frame fixing portion is sufficient if it can fix the lighting heat insulating material frame, and the L shape may be rounded.

The shape of the clasp or clip is not particularly limited. For example, as described above, the shape of the cross section shown in FIG. 10A is a U shape or a deformed U shape, Examples include a shape having a S-shaped or modified S-shaped cross section as shown in b), a shape having a L-shaped or modified L-shaped cross section as shown in FIG.

Further, the thickness of the portion inserted into the air tight structure frame or the glazing channel is not particularly limited, but is preferably 1 mm or less because insertion can be performed more smoothly. The thickness is more preferably 0.6 mm or less. Moreover, it is preferable that the part inserted in the said air tight structure frame or a glazing channel part is a taper shape so that a front-end | tip part may become thinner.

The method for fixing the daylighting heat insulating material to the air tight structure frame is not particularly limited, a method using a double-sided tape or a butyl rubber tape, a method using a caulking agent such as a silicone caulking agent, a method using an adhesive previously applied to the inside of the air tight structure frame, Examples thereof include a method of using pins, clips, and protrusions previously installed inside the air tight structure frame, a method of through-fixing with screws, nails and the like.
Although there is an advantage that construction is easier if the lighting insulation material is fixed to the air tight structure frame, it is not always necessary to fix it. If not fixed, the heat insulating material can be easily replaced, or if one heat-reflective film is used as the base material, the sunlight can be taken in or reflected every summer and winter season. There is also an advantage that it can be installed by replacing the front and back sides so that it can be effectively demonstrated.

By using the air tight structure frame, by fitting the window glass part and the lighting insulation material, it can be easily removed from the window glass part without damaging the lighting insulation material. It can be attached to the window glass again.
The peripheral member of the air tight structure frame is not particularly limited, and processing may be added to improve the installation state and workability. Specifically, for example, a molding member or foam tape attached in advance to the outer portion of the air tight structure frame may be used so as to completely fill the gap between the glass opening and the air tight structure frame. By attaching a molding member or foam tape, it is possible to completely suppress the condensation of the opening glass. Further, in order to increase the sealing performance and construction accuracy of the corner portion, an L-shaped corner sealing cap may be prepared in addition to the linear member and attached before and after the construction of the air tight structure frame. In order to fix the air tight structure frames cut in a straight line for the purpose of improving the bondability of the corner portions, an L-shaped fitting or the like installed inside the air tight structure frame may be attached.

The fitting method using the air tight structure frame will be described in detail with reference to the drawings.
FIG. 1 is a schematic diagram showing an example of a fitting portion between a window glass portion of a simple heat insulating window of the present invention and a daylight insulating material.
In FIG. 1, in the simple heat insulating window 1, the window glass portion 2 and the daylight insulating material 3 are fitted together by an air tight structure frame 4.
The air tight structure frame 4 includes a detachable frame member 41 and a pressing member 42. The frame member 41 is arranged in a seal frame shape with an adhesive 411 around the periphery of the window glass part 2. The lighting heat insulating material 3 is disposed inside the seal frame made of the frame member 41 so as to be in contact with the seal frame. In this state, the presser member 42 is attached to the frame member 41. Since the holding member 42 has the projection-shaped lighting heat insulating material pressing portion 421, the lighting heat insulating material 3 is securely fixed. When the lighting heat insulating material 3 is removed, it is only necessary to remove the pressing member 42 from the frame member 41.

FIG. 2 is an example in which the shape of the fitting portion of the air tight structure frame is different from that in FIG. 1, but a gap may be interposed between the daylighting heat insulating material surface and the glass as shown in FIG. 2.
Moreover, the frame member 41 may be arrange | positioned at the peripheral part of the window glass part 2 like FIG.1 and FIG.2 (a), and is arrange | positioned at the sash frame 9 like FIG.2 (b). Alternatively, as shown in FIGS. 2C and 2D, the frame 13 may be arranged. By arranging the frame member 41 in the sash frame 9 or the frame 13, heat insulation can be performed including the sash frame and the air layer between the sash frame and the frame, and the heat insulation can be further improved.
Further, the frame member 41 is arranged such that the male part of the frame member 41 faces the vertical direction with respect to the window glass part 2 as shown in FIGS. 1, 2 (a), 2 (b) and 2 (c). As shown in FIG. 2 (d), the male part of the frame member 41 may be arranged so as to face the horizontal direction with respect to the window glass part 2.

FIG. 10 shows an example in which the method for fixing the airtight structure frame is different from those in FIGS. 1 and 2.
The frame member 41 is fixed by an adhesive 411 in FIGS. 1 and 2, but in FIG. 10, by inserting and fixing a fastener 412 to the glazing channel 8, the peripheral portion of the window glass portion 2 is fixed. Further, they are arranged in a seal frame shape. In the case of the fixing method as shown in FIG. 10, when removing the daylighting heat insulating material 3, the holding member 42 may be removed from the frame member 41 as in FIGS. 1 and 2, but the whole fastener 412 can also be removed. . By using the fixing method as shown in FIG. 10, the daylighting heat insulating material can be applied more easily and can be easily removed.

When the window glass portion has a large area, a single daylighting heat insulating material may not be used, but a plurality of daylighting heat insulating materials may be arranged by dividing the entire surface of the large area window glass portion. Although the fixing method of the lighting insulation material in such a case is not specifically limited, The following methods can be considered.
For example, as the air tight structure frame, for example, there is a method of using the peripheral air tight structure frame 5 as shown in FIG. 3 and the central connecting part air tight structure frame 6 as shown in FIG. Moreover, in order to improve the designability of the junction part of the air tight structure frames 5 for peripheral parts, the method of using the corner part cap 7 as described in FIG. 5 is also mentioned. Furthermore, the method of filling the junction part of the air tight structure frames 5 for peripheral parts with a caulking material is also mentioned. In a method using such a caulking material, the joint can be made inconspicuous by selecting a transparent caulking material.

FIG. 6 illustrates a procedure for constructing a plurality of daylight insulating materials 3 on the window glass portion 2 using the airtight structure frame 5 for the peripheral portion, the airtight structure frame 6 for the central connecting portion, and the corner portion cap 7. .
In this construction method, first, the frame member 51 of the peripheral airtight structure frame 5 is bonded to the outer periphery of the window glass portion 2 (FIG. 6A). Next, the frame member 61 of the airtight structure frame 6 for the central connecting portion is bonded to the center of the window glass portion 2 (FIG. 6B). Next, the two lighting heat insulating materials 3 are installed in two regions surrounded by the frame member 51 of the peripheral airtight structure frame 5 and the frame member 61 of the central connection airtight structure frame 6 (FIG. 6 ( c)). Next, the holding member 52 of the air tight structure frame 5 for the peripheral portion and the press member 62 of the air tight structure frame 6 for the central connecting portion are fitted (FIG. 6D).
