Description

  The present invention provides a heat-shielding sheet using a highly reflective material or a highly reflective material against radiant heat, such as aluminum foil, directly on the surface of a building, such as a floor, wall, roof, partition (hereinafter referred to as a wall surface). Energy saving can be achieved by installing or installing a heat shield using a material with high reflectivity against radiant heat, such as aluminum foil, between the exterior and interior materials and the housing to form a static air layer. A thermal barrier insulation method for a building to be visited.

  In building, heat insulation paint is applied to the outer wall of the frame or heat insulation sheets are applied on the roof to provide heat insulation. In addition, there is a construction method in which aluminum foil is directly attached to the structural frame, but a ventilation construction method is adopted. As in the present invention, a construction method in which a heat shielding sheet using a material having high reflectivity or a material having high reflectivity with respect to radiant heat, such as aluminum foil, is attached to a structural frame of a building and a still air layer is provided has been provided so far. It has not been.

According to reports from many institutions throughout the United States, most of the heat loss in buildings and other spaces is due to radiant heat, accounting for 65 to 80 percent. Therefore, unless the radiant heat is reduced, the heat insulation performance of the building cannot be improved, and it is difficult to significantly reduce energy. However, the materials used for the walls of buildings have a low function of reflecting radiant heat, and most of them absorb and become heat. As a result, the wall surface became a heat storage body, and a lot of heating and cooling costs were required. This tendency increases as the volume of the wall increases, and there is a problem that the room is hot until midnight in summer and the room does not warm in winter.
Also, in the method of thermal insulation paint and thermal insulation sheet, since the thermal insulation material is constructed so that it directly touches the outside air, its performance will also deteriorate over time due to the influence of light, wind and dust, etc. The construction was mainly on the outdoor side, and there was a problem that there was not much effect on the radiant heat from the indoor side.
Furthermore, there is a construction method in which an aluminum foil or the like is directly attached to a structural housing such as concrete, but a ventilation construction method is adopted in which air is passed between the exterior material and the housing. However, aluminum foil etc. is weak in convection heat and causes condensation, and the ventilation method exhausts heat from the outside air, but at the same time also exhausts internal heat, so the energy saving effect in the building is insufficient There was a problem.
The present invention is a thermal barrier insulation method for a building to solve this problem.

In order to solve the above problems, the present invention reflects the reflection of a material having high reflectivity against radiant heat, such as two or more aluminum foils, between an exterior material and an interior material of a building wall such as a floor, a wall, a roof, and a partition. This is a heat insulation and heat insulation method for a building in which a body edge is provided so that a surface and two or more still air layers are formed.
If the building's housing is dry, attach heat-shielding sheets using high-reflectivity materials or high-reflectivity materials, such as aluminum foil, directly to both sides of the housing, and attach them to the outer sides of the building's body edges, etc. What is necessary is just to attach an exterior material and an interior material so that a still air layer may be formed.
If the building housing is non-dry, attach a heat-shielding sheet that uses high-reflectivity materials or a highly reflective material against radiant heat, such as aluminum foil, directly to either side of the housing, and to the outside of it An interior or exterior material is attached so that a still air layer is formed by the edge, etc., and the other is a shield with at least one reflective surface using a material having high reflectivity against radiant heat such as aluminum foil. A heat shield such as a heat sheet or a heat shield board is attached between the housing and the interior material or the exterior material so that a static air layer is formed by a double-sided joint edge or the like. In this case, in order to discharge moisture etc. inside the housing, when a heat shield sheet using a material with high reflectivity or high reflectivity with respect to radiant heat such as aluminum foil is directly attached to the exterior surface side of the housing A ventilation port that penetrates from the exterior material to the wall surface of the enclosure, and a heat-shielding sheet that uses a highly reflective material or a highly reflective material for radiant heat, such as aluminum foil, are directly attached to the interior surface side of the enclosure. In this case, it is preferable to provide a ventilation port penetrating from the exterior material to the interior surface side of the heat shield sheet using a material having high reflectance or a material having high reflectance with respect to radiant heat such as aluminum foil.
As another construction example, a heat shield sheet or a heat shield board having a reflective surface using a material having high reflectivity with respect to radiant heat, such as aluminum foil, is provided between the casing and the exterior material or interior material. There is also a construction method in which the heat body is attached so that a static air layer is formed by a double-sided joint edge or the like.

BEST MODE FOR CARRYING OUT THE INVENTION

The best mode for carrying out the present invention will be described below.
A material having high reflectivity with respect to radiant heat such as aluminum foil has a performance of reflecting 97% or more of radiant heat. The present invention utilizes this performance. Between the exterior and interior materials of the building, a reflective surface of a thin material having a high reflectivity with respect to radiant heat, such as at least two aluminum foils, and 2 This is a construction method that has a static air layer of more than one place. However, heat-shielding sheets that use materials with high reflectivity or high reflectivity against radiant heat, such as aluminum foil, exhibit high performance against radiant heat, but not against convection heat or conduction heat. In order to be effective, a static air layer is formed so as not to be affected by this.
FIG. 1 shows a structure 3 having a high-reflectivity material 3 or a heat-shielding sheet using a high-reflectivity material, such as aluminum foil, directly attached to both surfaces of a structure wall 4 etc. A still air layer is formed by the above, and the exterior material 1 and the interior material 5 are attached to both outer sides thereof, and the structural frame of the building is used as a structural material and a heat insulating heat insulating material.
Fig. 2 shows that the exterior wall of the housing wall 4 is attached with a material 3 with high reflectivity against radiant heat, such as aluminum foil, or a heat-shielding sheet using a material with high reflectivity, and the outside is stationary by the body edge 2, etc. An air layer is formed, and the exterior material 1 is attached from the outside. On the indoor side, a heat shield 6 such as a heat shield sheet or a heat shield board using a material 3 having high reflectivity with respect to radiant heat such as aluminum foil is sandwiched between the two shell edges 2 and the like. Is formed between the inner wall surface of the housing wall 4 and the interior material 5. The heat shield 6 such as an aluminum hoist has at least one material 3 having a high reflectivity with respect to radiant heat such as aluminum foil. If the housing wall 4 is not sufficiently dried, a ventilation port 7 penetrating the exterior material 1 and the housing wall 4 may be provided to discharge moisture generated from the housing wall 4.
FIG. 3 shows that a heat shield 6 such as a heat shield sheet or a heat shield board using a material 3 having a high reflectivity with respect to radiant heat, such as aluminum foil, is fixed on the exterior surface side of the frame wall 4, etc. An air layer is formed, and the exterior material 1 is attached from the outside. In addition, if the housing wall 4 is not sufficiently dried, a ventilation port that penetrates the exterior material 1 and the heat shield body 6 such as an aluminum foil is provided to discharge moisture generated from the housing wall 4. good.
FIG. 4 shows a still air layer formed by sandwiching a heat shield 6 such as a heat shield sheet or a heat shield board using a material 3 having high reflectivity with respect to radiant heat, such as aluminum foil, on both sides between two trunk edges 2 and the like. It is formed and attached between the inner wall surface of the frame wall 4 and the interior material 5.
In any case, between the exterior material and the interior material, a reflective surface using the material 3 having high reflectivity with respect to radiant heat such as at least two aluminum foils and two or more static air layers were formed. It is a construction method.

The invention's effect

Aluminum foil attached to both walls of the building's enclosure, such as aluminum foil, which has a high reflectivity or a high-reflectivity material, the heat shield sheet uses more than 97% of the radiant heat passing through the wall. Therefore, only about 3% will enter the wall of the housing. Therefore, heat from the outside is not taken into the indoor side, and heat from the indoor side does not escape to the outside of the room, so that high heat shielding properties are obtained. In addition, the thickness of the frame wall plays a role of a heat insulating material, and the heat insulating performance is also improved. This effect increases as the thickness of the housing wall and the like increases. As a result, the building structure can be made into a high-performance thermal insulation.
As shown in FIG. 2, when the housing wall or the like is not sufficiently dried, moisture on the housing wall or the like is discharged from the indoor side, but the same effect is exerted on the reflectance of the radiant heat. However, since the number of still air layers is increased by one, the heat insulating performance is further improved as compared with FIG.
As shown in Fig. 3, when a heat shield such as aluminum foil that uses a material with high reflectivity for radiant heat, such as aluminum foil, is attached to form a static air layer on the outer wall of the housing, the radiant heat reflectivity Are equivalent, but because the heat shield is thin, it is inferior to the method of FIG. However, there is an advantage that the construction is simple and the indoor space is not narrowed.
FIG. 4 shows a construction method in the case where a heat shield or the like cannot be constructed on the outside of the frame wall or the like, but the reflectance of the radiant heat is equivalent to the construction method of FIG. 1, FIG. 2, and FIG. Although this method has problems such as being easily affected by the heat stored in the frame wall and the like and the interior space being narrowed, it has the advantage that it can be applied to any building because it is easy to construct.
As described above, although each method has a difference in construction method, it can not only cut most of the radiant heat that passes through spaces such as buildings, but can also reduce conduction heat and convection heat. Energy saving effect can be created.
In addition, since the mounting positions of these aluminum foil and other highly reflective materials are within the space surrounded by the exterior and interior materials, they are affected by the natural environment such as dust and light outdoors and indoors. Absent. Therefore, stable performance can be maintained for a long time.
Furthermore, since a material having a high reflectivity with respect to radiant heat such as aluminum foil reflects electromagnetic waves, it is also effective as a countermeasure against electromagnetic waves near a high-voltage line.
