In winter, the low emissivity helps to retain the warmth of the indoor temperature. In winter, aluminum heat-reflective insulation acts like aluminum foil wrapped around baked sweet potatoes. Due to the low emissivity of the foil, it prevents the warm indoor temperature from escaping. (Heat always moves from warm areas to cold areas.) In summer, the foil installed in the attic reflects the heat from the sun before it enters the building, keeping the indoor temperature cool. Additionally, the bubbles sandwiched in the foil prevent heat flow through contact, and since they are solid, they do not cause heat rise and also serve as a moisture barrier.

Unlike other insulation materials, it creates an optimal environment for animals with the aluminum foil exposed on the inside. For example, the heat released from livestock's bodies is reflected by the aluminum foil, bouncing that heat back to the livestock. This heat subtly raises the slightly cooler surrounding temperature, making it comfortable for the animals. In other words, it also saves on heating costs, and even during the hot summer months, it reflects the sun's heat, ensuring that the internal temperature does not exceed the outside air. In winter, it prevents warm indoor air from escaping, creating a stable temperature throughout the enclosed building without forming temperature layers from floor to ceiling, thus creating an ideal environment. Additionally, the thermal insulation material repels moisture and can be cleaned with a high-pressure washer, making building disinfection easy. For more details, please download the catalog.

Aluminum heat-insulating materials can be used without any issues for underfloor heating. By installing the heat-insulating materials at the bottom of the floor joists or in the middle of the floor joists where underfloor heating is installed, you can save on heating costs and maintain a comfortable space for a longer period. Additionally, when heat-insulating materials are installed in the underfloor space, they reflect the cold air from the ground back to the ground, while the warm air inside bounces off the heat-insulating materials back into the room, helping to maintain a comfortable floor temperature and save on heating costs.

Aluminum heat-insulating materials reflect cold outside air and ground heat in winter, returning warmth to the interior. In summer, they reflect heat rays (electromagnetic waves), blocking radiant heat from the outer walls and preventing the cooling energy inside from escaping. Heat transfer continues until absolute zero temperature (0°C absolute temperature is -273°C) is reached, so aluminum heat-insulating materials are effective in any climate throughout spring, summer, autumn, and winter.

Heat-insulating materials have a very low thermal emissivity, minimizing radiative heat from the foil itself, while the highly reflective aluminum foil reflects heat from adjacent buildings, thereby minimizing the intrusion of radiative heat from the outdoors. Additionally, since it is a solid material, there is no heat transfer or moisture intrusion within the insulation. In other words, there is no insulation material as perfect as heat-insulating materials. Okuda Lumber Store is a long-established lumber company founded in 1934 in Sakai City, Osaka Prefecture.

Aluminum thermal insulation sheets were initially developed in the space industry as reflective insulation materials for spacecraft and spacesuits used in ultra-high heat environments. Their high insulation performance serves as a barrier that prevents the transfer of radiant heat, acting as a complete barrier against air, steam, and other elements. The structure consists of two porous sheets (bubble packs) laminated on top of a polyethylene film, with an additional layer of polyethylene coated with aluminum placed on the outside of the bubble packs. This aluminum thermal insulation sheet, which has excellent insulating properties, is an environmentally friendly material that contributes to comfortable living in both hot and cold conditions. Furthermore, it significantly helps in saving costs and conserving energy. For more details, please download the catalog.
