Residential heat insulation construction, and heat insulator to be used

Abstract

It is intended to reduce heat storage in a heat insulator applied to the outer periphery of a living room in a residential building, to simplify construction work, to save energy, and to rationalize retention of living environment. The outer surface of a heat insulating member (2) disposed on the outer periphery of a partition panel in a roof, ceiling, wall or the like surrounding a living room is covered with a heat shielding member (1) having a heat reflecting foil, thereby preventing transmission of radiant heat due to heating to the heat insulating member (2), reducing the heat storage in the heat insulating member (2).

Description

technical field [0001] The invention relates to the improvement of the heat insulation structure of a house, and belongs to the technical field of house construction. Background technique [0002] In a general wooden structure building, the inner layer of the roof is provided with ventilating openings on the horizontal outer wall, etc., and the temperature inside the inner layer of the roof is assimilated with the temperature of the outside air as much as possible. The construction area, sunshine conditions, and seasons sometimes have high temperatures (above 70°C). [0003] In this way, in order to reduce the bad influence on the living room due to the heat in the inner space of the roof, construction of blown fiber heat insulating parts or rigid urethane foam heat insulating parts is generally carried out inside the ceiling of the living room. [0004] Figure 8 It is the existing structure of constructing the rigid urethane foam heat insulation part 2 on the ceiling of t...

Problems solved by technology

[0006] Moreover, even heat insulating members with high heat insulating performance such as rigid urethane foam heat insulating parts 2 or fibrous heat insulating parts 2 for blowing in, if they are heated and exposed to the sun for a long time, these heat insulating parts will be damaged. Part 2 will also absorb heat and become high temperature, so that the high transmission heat T 3 By communicating to the room R, it brings obstacles to the maintenance of a comfortable environment in the room, that is, the maintenance of an appropriate temperature

Moreover, even if the external air T 1 The heat insulation component 2 cools down slowly due to its heat capacity as a heat storage body due to the temperature drop. Therefore, due to the daytime R 0 The heat insulating member 2 that insulates high temperature releases heat at night as a heat storage body, and there is a problem that it becomes an unsuitable load to the air conditioner like the air conditioner in the living room R.
