With aluminum insulation materials, heat loss and heat gain can be prevented, making it cool in the summer and warm in the winter, especially alleviating the heat during summer nights. In other words, it can significantly reduce heating and cooling costs. Additionally, by applying it to the inside of garages or warehouses, light is reflected, brightening the interior and reducing the need for lighting fixtures. For more details, please download the catalog.

By using thermal insulation materials, you can easily increase the insulation performance of your home. You can use it under the floor to keep the floor warm, on the walls of the garage to create a comfortable workspace year-round, and on the roof rafters to block summer heat radiation, among various other methods to enhance comfort and reduce utility costs. Simply applying it inside a cooler box provides excellent cooling effects. It is also effective for insulation bags. When applied to the front windshield of a parked car, it helps reduce the temperature rise inside the car due to direct sunlight. Applying it to the inside of a doghouse can help maintain a comfortable temperature inside. For more details, please download the catalog.

• Roof and gutter construction

In winter, the low thermal emissivity prevents the warm indoor temperature from escaping. In winter, aluminum heat-reflective insulation acts like aluminum foil wrapped around baked sweet potatoes. Due to the low thermal emissivity of the foil, it helps retain the warm indoor temperature (heat always flows from warmer areas to cooler ones). In summer, the foil installed in the attic reflects 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. For more details, please download the catalog.

• Roof and gutter construction

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, causing that heat to bounce 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 temperature. In winter, it retains the warm air indoors, preventing the formation of temperature layers from floor to ceiling in sealed buildings, stabilizing the entire area at a consistent temperature and 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, unlike insulation materials such as glass wool, do not allow any pests or rodents to breed. Additionally, since the surface can be cleaned with a high-pressure washer, disinfecting the building is also not a problem. It does not attract moisture, so there is no concern about mold. For more details, please download the catalog.

• glass wool

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. For more details, please download the catalog.

• Insulation work

Aluminum heat-insulating materials are not much more expensive than glass wool insulation. However, once installed, aluminum heat-insulating materials do not require replacement or additional work due to moisture or other influences, so you only incur the installation cost. Additionally, they are lightweight and easy to install, which can reduce construction costs. Moreover, past test data and feedback from consumers using aluminum heat-insulating materials demonstrate that they perform far better than glass wool insulation. For more details, please download the catalog.

The installation of aluminum heat-insulating materials can be done easily. No special clothing or masks are required. With scissors, a knife, measuring tape, goggles (if possible), and a stapler, you can complete the installation. In the unlikely event that the surface tears or rips, it can be easily repaired with foil tape.

Aluminum heat-insulating materials reflect cold outside air and ground heat in winter, returning warmth indoors. In summer, they reflect heat rays (electromagnetic waves), block radiant heat from the outer walls, and prevent indoor cooling energy from escaping outside. Heat transfer continues until absolute zero temperature (0°C absolute 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 radiant heat from the outdoors. Additionally, being 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.

Aluminum heat-insulating sheets were initially developed in the space industry as reflective insulation materials for spacecraft and spacesuits used in ultra-high-temperature 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) layered on top of a polyethylene film, with an additional layer of polyethylene coated with aluminum placed over the outside of the bubble packs. This aluminum heat-insulating sheet, with its excellent insulation properties, is an environmentally friendly material that contributes to comfortable living in both hot and cold conditions. Moreover, it significantly helps in saving costs and conserving energy. For more details, please download the catalog.

The thin airtight insulation sheet "CBF Concrete Barrier Foil" is a thin airtight insulation sheet that sandwiches a special aluminum with excellent radiant heat effect between polyethylene bubbles. When used with concrete, it is optimal as insulation under concrete because the aluminum foil does not come into direct contact with the concrete. Additionally, it is unaffected by moisture, thus serving effectively as a moisture barrier. Furthermore, it has resistance to bacteria and does not promote mold growth, achieving an energy-efficient and comfortable living space.

As an example of the use of aluminum thermal insulation sheets, we introduce their application under roof plywood. By using aluminum thermal insulation sheets beneath the roof plywood, the air layer created between the plywood and the barrier sheet reflects the heat directly hitting the roof, while the foil sheet on the opposite side prevents heat from being conducted indoors. During installation, spread the thermal barrier sheet over the rafters beneath the roof plywood, allowing it to hang down about 5 cm, and secure it with a staple gun. Then, fix the roof plywood in place with nails from above. Okuda Lumber Store is a long-established lumber company founded in 1934 in Sakai City, Osaka Prefecture.
