Common problems that can occur—have you ever had such an experience? Even though there is high-performance insulation, the inside of the house is hot on summer nights... Why is it that on summer nights, when it is cool outside, the inside of the house is hot? Even though the insulation is properly installed, the room becomes too hot to sleep without using air conditioning. To understand the reason for this, let's take a look at the characteristics of insulation.

Properties of Insulation Materials Insulation materials slow down the transfer of heat through many layers of air. Insulation is made up of numerous layers of "air." Since air has a low thermal conductivity, the more layers of air there are, the slower the heat transfer becomes. Therefore, as the thickness of the insulation increases, its insulating performance improves. When people hear "insulation material," they often think of it as something that "stops heat," but more accurately, it is something that "slows down the transfer of heat." It absorbs heat while slowing down its transfer, thus providing thermal retention. Futons and down jackets have the same structure as insulation materials.

When you air out the futon, it becomes warm. When the futon is aired out, it absorbs the sun's heat (radiant heat) and becomes cozy. Since "insulation material" equals futon, the "insulation material" absorbs heat.

As a result, it's as if the house is wrapped in a dried futon! The heat from the summer sun is absorbed by the insulation, causing the inside of the house to become hot.

There is heat that cannot be stopped by insulation materials. As a solution >> Add a 99% pure aluminum heat-reflective sheet, Thermo Barrier, which reflects heat that cannot be stopped by insulation materials!! The ideal shape of insulation materials is to effectively stop all three types of heat transfer—conductive heat, convective heat, and radiant heat—by using insulation materials that are highly effective against conductive and convective heat in combination with Thermo Barrier, which excels at reflecting radiant heat.

With the power of heat shielding, summer is cool and winter is warm. ThermoBarrier is a heat-insulating material that cuts 99% of radiant heat, which cannot be prevented by insulation alone. By using ThermoBarrier on your home's roof and walls, you can suppress the rise in building temperature caused by solar radiant heat in summer, lowering the perceived temperature. This makes it possible to reduce the use of air conditioning. In winter, the indoor temperature tends to escape outside. Since ThermoBarrier reflects the radiant heat generated indoors back into the room, it helps prevent the drop in temperature inside the building. Utilizing this function, ThermoBarrier plays a crucial role in achieving "cool in summer and warm in winter" easily and affordably.
