Description

[Detailed description of the invention] By pasting it on the plate glass of a window or glass door, this invention not only provides heat insulation and soundproofing effects, but also makes it possible to adjust indoor humidity and has a moisture absorption effect.

This invention relates to a heat insulating material for plate glass that aims to obtain relatively soft light when daylighting.

Insulating materials made by pasting together multiple sheets of synthetic resin films with a closed-cell air layer in between have been known, but they have never been used as insulating materials for plate glass; There isn't.

In addition, regarding the soundproofing properties of window glass, we exclusively increase its thickness,
Or, multi-layering is considered, and layering of different materials is not considered.

However, this invention solves the above-mentioned problems of the conventional method, as it solves the above-mentioned problems of the conventional method, and also allows moisture-absorbing paper to be layered on one side of a synthetic resin film with closed cells, and the other side is used as the glass adhesion surface. The dew point is reduced, and there is no risk that the generated water droplets will be absorbed by the moisture-absorbing paper and stain the surrounding area, and the moisture in the moisture-absorbing paper will naturally evaporate, controlling the humidity of the indoor air. At the same time, it provides an excellent material with extremely good heat and sound insulation properties.

This invention will be explained below based on embodiments shown in the drawings.

A heat insulating material 5 is formed by inserting a synthetic resin film 2 having a large number of disk-shaped uneven parts between transparent synthetic resin films 1 and 3 and pasting them together through an air layer 4 having a large number of closed cells 4a. A shoji paper 6 is layered over the entire surface of the heat insulating material 5, and a double-sided adhesive tape 8 is applied to the periphery of the other surface of the heat insulating material 5 for attaching the heat insulating material 5 to the glass plate 7. It is pasted.

To use the heat insulating material for plate glass shown in the above embodiment, the release paper 8a of the double-sided adhesive tape 8 is peeled off, and the shoji paper 6 is placed on the indoor side of the window glass or glass door 7, with the shoji paper 6 facing the indoor side. .

If the heat insulating material for sheet glass shown in the above embodiment is attached to the indoor side surface of a window glass or a glass door, the air layer 4 of the heat insulating material 5 can provide a heat insulating effect and a soundproofing effect.

In order to obtain the above effect, it is preferable that the thickness of the air layer 4 is approximately 2 mm.

Further, according to the above embodiment, since the air layer 4 has a large number of disc-shaped closed cells 4a, air convection does not occur within the air layer 4, and a high heat insulation effect can be obtained. 4 does not necessarily have to have disc-shaped closed cells; for example, a heat insulating material may be formed by pasting a synthetic resin film 2 bent in a wavy cross section on one side of the synthetic resin film 1. (Figure 3).

Furthermore, since the shoji paper 6 is layered on the inner side surface of the heat insulating material 50, the indoor humidity can be adjusted by the shoji paper 6.

That is, when the indoor humidity is high, the shoji paper absorbs moisture, and when the indoor humidity is low, the moisture in the shoji paper naturally evaporates and is released into the room.

Therefore, even if there is a large temperature difference between indoors and outdoors, there is no risk of a dew point occurring on the indoor glass plate surface.

In addition, since the shoji paper 6 was used in the above example, the glass window equipped with the heat insulating material for plate glass looks as if it were a shoji window, but it is not necessarily necessary to use shoji paper, and it is not necessary to use shoji paper. Any paper can be used as appropriate.

Further, according to the above embodiment, since the double-sided adhesive tape 8 is pasted on one side of the heat insulating material 5, it can be attached to the window glass extremely easily.
) may be provided.

In addition, according to the above embodiment, a transparent synthetic resin film is used, so the transmittance of natural light is high, but it is not necessarily necessary to use a transparent film. Since the moisture-absorbing paper is layered on one side of the heat-insulating synthetic resin material, excellent heat-insulating and sound-insulating effects can be obtained due to the synergistic effect of the heat-insulating sound-insulating effect of the heat-insulating synthetic resin material and the heat-insulating sound-insulating effect of the moisture-absorbing paper.

Furthermore, dew points are less likely to occur on the surface of the heat-insulating synthetic resin material, and there is no risk that the water droplets that occur will be absorbed by the moisture-absorbing paper and stain the surrounding area.

Furthermore, the moisture in the absorbent paper evaporates naturally, controlling the humidity of the indoor air.

In addition, the moisture-absorbing paper has the effect of allowing relatively soft light to be obtained during daylighting.
