Description

Insulation Windows Using Film

The present invention relates to a heat insulating window using a film, and in particular, to a single window (layer) or a multi-layer glass sheet, a film member obtained by vacuum-depositing an adhesive, a coloring film, and a metal film on a polyester fabric is attached to the heat transmission rate of heat loss through the glass door Will be lowered.

In general, most of the energy we use comes from fossil fuels, and scientists in this field predict that all of the world's fossil fuel will be depleted within a few years, even with a 1% increase in consumption. It is known to be a major cause of global warming and cause climate change such as sea level rise, and its use is restricted to individual countries by various conventions in the international community. This situation has led to investments in energy-saving facilities for efficient use of energy, which has led to the conversion of buildings to low-consumption structures and the regulation of energy consumption regulations for new buildings.

In this regard, windows are important mediators that penetrate the interior and exterior of buildings, but these windows are ten times more vulnerable to thermal conductivity than walls. Normally, about 40% of the energy consumption of buildings is made through windows. In Korea, where energy import is 98%, increasing the insulation rate of buildings through windows is a shortcut to energy saving and further strengthening the competitiveness of the national economy. It will be too natural to be connected directly to Edo. In fact, domestic energy demand is approximately 165.6 million tons (oil equivalent) in 2000, of which the total national energy consumption in the domestic building sector is known to be about 24% of the total energy consumption. It is known that 40% is done through windows.

For reference, the Korea Energy Management Corporation's energy performance analysis of a three-year-old domestic building showed that the cooling load due to the maximum cooling load aggression was the highest at 35%, and the cooling load through the window (electric conduction, solar radiation) was 31% at 66%. % Was generated through windows and doors. In addition, 63% of the factors caused by window and door aggression during heating loads. And the heating load generated by the conduction of the window reached 29%. This shows that the loss rate due to the wall is 5%, but the waste and loss of energy through the glass window is large.

For this reason, in Korea as well as internationally, buildings strictly regulate the insulation rate of windows for energy saving through windows, which are the absolute elements of energy saving, and various products have been developed and used to increase the thermal efficiency of windows. In particular, most industrialized countries such as Germany and Europe and the United States stipulate heat-transfer rates in the Building Act to save energy in buildings, making them more insulated and airtight than existing windows. In the case of Japan adjacent to us, the glass heat permeation value of the building insulation method is 2.0kcal / ㎡hr ℃, and 2.60kcal / ㎡hr ℃ in the UK, which is warmer than Korea, the use rate of high efficiency insulation window This is high. In Korea, the heat permeation value of windows and doors is currently set at 2.9kcal / m 2hr ℃, but due to the stricter regulations, it is difficult to satisfy the insulation regulations even with double-layer glass.

In order to solve the above problems, there is a "insulation window" of the registration number 1991-6404 and the "laminated glass panel" of the registration number 20-263321 disclosed in the Korean Utility Model Publication, but the prior art also It does not minimize the heat loss through the glass door.

Accordingly, an object of the present invention is to provide an insulation window using a film that eliminates the above drawbacks and minimizes the heat transmission rate that causes heat loss through the window from the building, thereby reducing energy consumption due to maximization of thermal energy efficiency. It is.

Another object is to provide an insulation window using a film having a soundproofing that prevents the glass from being easily broken, and does not scatter everywhere even if the glass of the window is broken.

Insulating windows using the film of the present invention to achieve the above object is a window frame made of a door frame related to the invention of claim 1, a plurality of glass plate materials disposed at regular intervals on the door frame; Each film is attached to one surface of the glass plate to have a low thermal permeability, and is formed by vacuum deposition of an adhesive, an ultraviolet absorbing film, and a metal film on a polyester fabric, and one surface of the film member having an adhesive surface for attaching to the glass plate. It is characterized by including.

In the above, it is preferable that the anti-scratch coating film is further formed on the surface opposite to the adhesive surface of the film member.

Hereinafter, with reference to the accompanying drawings will be described in detail a more preferred embodiment of the insulating window using a film according to the present invention.

1 is a perspective view showing a part of the insulating window using a film according to the present invention.

As shown in the drawings, the insulating window 100 according to the present invention is a plurality of airtightly fixed to the door frame 120 at a predetermined interval by a spacer 122 installed along the entire length of the door frame 120. The multilayer glass 140 formed of two glass plates 142a and 142b is provided. The spacing d of the glass plates 142a and 142b is approximately 6 or 12 mm, and the spacing d is arbitrarily determined according to the thickness t of the glass plates 142a and 142b. For reference, the thickness t of the glass plates 142a and 142b used for the multilayer glass 140 may be 12 mm or 6 mm.

Insulating film members 160a and 160b, which are the most important parts of the present invention, are attached to the entire one surface of the glass plates 142a and 412b. The insulating film members 160a and 160b will be described in more detail with reference to FIGS. 2A and 2B.

FIG. 2 is an enlarged cross-sectional view taken along line I-I of FIG. 1, and FIG. 3 is an enlarged view of portion A of FIG. 2.

As shown in the drawing, the heat insulating film member 160a includes a polyester fabric 161, a metal film 162, an adhesive 163, and an ultraviolet absorbing film 164, and one of the ultraviolet absorbing films 164. An adhesive surface 165 used to attach to the glass plate 142a is formed on the surface thereof, and an anti-scratch coating film 166 is formed on the opposite surface thereof.

In more detail, the plate-like metal film 162 is laminated on one surface of the polyester fabric 161 having a predetermined width, and the previously prepared adhesive 163 is coated on the surface of the metal film 162. After placing the ultraviolet absorbing film 164 on the applied adhesive 163, they form a single thin film structure through a conventional vacuum deposition or sputtering method, and both surfaces of the thin film thus obtained are coated and bonded together. The thin film member 160a having a thickness of about 0.1 mm formed with the adhesive surface 165 and the anti-scratch coating layer 166 is obtained through the process of. The adhesive surface 165 is provided with a protective paper that can be removed in use for the protection of the adhesive surface 165.

Polyester (PET) fabric 161 used in the manufacture of the thermal insulation film member 160a occupies the largest volume and weight of the components of the film member 160a, by the polyester fabric 161 Since the quality of the film member 160a is determined, it is preferable to use high quality rather than low grade.

The metal film 162 is made of aluminum, and the aluminum metal film 162 serves to block heat passing through the film members 160a. That is, in summer, direct heat and solar heat is blocked to reduce the cooling load in the room, and in winter, the internal heat loss is minimized to maximize the heating effect. In addition, in the multi-layered windows such as the present invention, the heat transmission rate is further minimized by the heat insulation action by the heat insulation film members 160a together with the gap d therein.

The laminating adhesives 163 are used to bond various materials (materials) in the structure of the film member 160a. The adhesive 163 is a mixture of two or more adhesive materials to form a single layer of thin adhesive (163).

The Ultraviolet UV Absorbers 164 are used to prevent damage to the polyester fabric 161 or the synthetic adhesive 163 of the film 160a from the ultraviolet rays of the sun. The ultraviolet absorbing film 164, that is, the UV controlling agent may be present between the adhesive 163 and the adhesive surface 165 or permeate the original polyester fabric 161. The ultraviolet absorber protects indoor furniture and fibers from fading and also maintains long-term preservation of the film member 160a.

The scratch resistant coating 166 is used to protect the outer surface of the film member 160a.

Although various kinds of adhesives are used in the manufacturing process of the film member 160a, since the adhesive is bonded in two construction methods during the installation of the film, adhesives forming the adhesive surface 165 are pressure sensitive. Pressure sensitive adhesives and water activated adhesives are used.

When the film member 160a is made using the pressure sensitive adhesive, the protective backing paper (not shown) is removed from the adhesive surface 165, and then the film members 160a of the glass member 142a are removed. Attach to the desired surface while applying pressure with a tool such as plastic hair, and if the film member 160a is made using the water-activated adhesive, first remove the protective backing paper from the film member 160a Evenly spray soapy water or other solution onto the surface of the glass plates 142a and the adhesive surface, and then attach the film members 160a to the glass surface, cut it out according to the glass size, and bite it with a tool such as rubber roller or plastic roller. This can be done while reducing the adhesion.

In the above embodiment, the insulating film members 160a and 160b are the same, and thus, only one of the insulating film members 160a has been described as an example. In the above embodiment, the window formed by attaching the film members 160a and 160b to the multilayer glass 140 has been described as an example. However, the window may be attached to the glass of the single layer (window) window. same.

Table 1 shows a comparison test result between the multi-storey windows and the existing windows and walls of the present invention configured as described above.

In Table 1, * indicates the interval d of glass (see Fig. 1) in the double glazing.

As can be seen from Table 1, the window with the heat insulating film of the present invention can be seen that the heat transmission rate is lower than the conventional double-glazed glass windows as well as the general walls, which proves that the heat insulating function is superior to that Will be.

Based on the results of the test results as shown in Table 1 above, a double-glazed window with a width of 1.52m and a height of 1.2m, which is a general standard for domestic glass windows, was calculated by dividing the heat loss per hour before and after improvement when the temperature difference was within 1 ℃. The result is as follows.

1. Heat loss before improvement (general laminated glass)

* General double layer glass heat transmission rate: 2.9kcal / ㎡hr ℃

<Heat Loss Rate of Regular Laminated Glass>

General laminated glass heat transmission rate X window area: 2.9 kcal / m 2 hr ° C. X (1.52 X 1.2) m 2 = 5.22 kcal / hr ° C. In other words, the loss before improvement of ordinary laminated glass is 5.22 kcal / hr ° C.

2. Heat loss after improvement (when the film members of the present invention are attached between the laminated glass)

* Thermal permeability of the present invention: 1.4kcal / ㎡hr ℃

<Heat loss rate of the double-glazed windows of the present invention>

Heat permeability rate of the double-glazed windows of the present invention x window area: 1.4 kcal / m 2 hr ℃ X (1.52 X 1.2) ㎡ = 2.52 kcal / hr ℃. That is, the total loss of multilayer glass using the film is 2.52 kcal / hr ° C.

<Energy saving ratio>

Compared with ordinary laminated glass: energy savings / loss before improvement X 100% = (7.12-2.71) / 7.12 X 100% = 61%.

As can be seen from the above calculation results, it can be seen that the energy consumption rate is also lower than that of the existing windows when using the multilayer windows using the heat insulation film of the present invention.

As described above, according to the present invention, by minimizing the heat transmission rate that causes the heat loss through the windows from the building to reduce the cooling load in the summer, and in the winter to maximize the thermal energy efficiency, ultimately energy consumption There is a saving effect. In addition, the glass of windows and doors are not easily broken, and there is a safety that does not scatter in all directions even if broken, and a soundproofing effect that blocks noise.
