The "Prox Thermal Insulation Sheet" is a thermal insulation sheet made from aluminum with a purity of 99%, which reflects up to 97% of radiant heat. By installing it under roofs or on machinery, it helps prevent indoor temperature rises and improves the environment in factories and warehouses during the summer, which can become "sauna-like." In tests conducted by our company, we measured the under-roof temperature in two buildings with the same structure on the same site and confirmed a temperature suppression effect of up to 10°C compared to uninstalled areas. After installation, there are no running costs, and it allows for measures against heatstroke while reducing CO2 emissions and electricity consumption. 【Features】 ■ High-quality corrosion-resistant coating prevents a decrease in reflectivity and deterioration of the sheet. ■ Non-combustible certification obtained, making it applicable to factories and warehouses with interior restrictions under fire safety laws. ■ Increases the thermal efficiency of equipment such as boilers, enabling energy savings. ■ Proven installation results on dryers, fryers, and baking machines. *For more details, please refer to the materials. Feel free to contact us as well. We are also providing materials that include installation examples.

In the detached house W, the second floor serves as a bedroom, and due to high temperatures in the summer, there was a concern about improving the efficiency of the air conditioning. Therefore, we implemented a ceiling insulation work by laying sheets above the insulation material. By suppressing radiant heat from outside, we can raise the air conditioning set temperature, which also contributes to energy savings. 【Construction Overview】 ■ Location: Fukuoka Prefecture, Fukuoka City ■ Roof Material: Wooden house ■ Area: Approximately 110m2 (ceiling space of the second floor) ■ Materials ・ Prox thermal insulation sheet (PRX-FN) ・ Stand light/cutter ・ Protective sheet *For more details, please refer to the PDF document or feel free to contact us.

In the T residence, a detached house, the second floor is occupied by the daughter’s family, who were facing the issue of wanting to somehow address the summer heat. To reduce radiant heat from outside and improve the effectiveness of the air conditioning, heat insulation work was carried out in the attic. In the T residence, the attic is high, and a heat insulation sheet was laid over the insulation material during the construction. 【Construction Overview】 ■ Location: Kitakyushu City, Fukuoka Prefecture ■ Roof Material: Wooden house ■ Area: Approximately 80m2 (attic of the second floor) ■ Materials ・ Prox heat insulation sheet (PRX-FN) ・ Stand light / Cutter ・ Protective sheets, etc. * For more details, please refer to the PDF document or feel free to contact us.

In the T company's president's detached house, the second floor, which consists of a bedroom and children's room, had the problem of being extremely hot during the summer. To improve the situation by reducing radiant heat from outside and enhancing the effectiveness of the air conditioning, a heat insulation construction using Prox Thermal Insulation Sheet (PRX-FN) was carried out in the attic. The work was completed in one day over an area of approximately 100m2. 【Construction Overview】 ■ Location: Fukuoka Prefecture, Fukuoka City ■ Roof Material: Steel frame house ■ Area: Approximately 100m2 (attic of the second floor) ■ Materials - Prox Thermal Insulation Sheet (PRX-FN) - Stand light/Cutter - Protective sheet *For more details, please refer to the PDF document or feel free to contact us.

In the M residence, a detached house, a family lives on the second floor of a two-family home and was facing the issue of wanting to somehow address the summer heat. To reduce radiant heat from outside and improve the efficiency of the air conditioning, we carried out heat insulation work in the attic by laying sheets above the insulation material. Since the M residence has a 24-hour ventilation system, all wiring and ductwork were placed on top of the sheets. 【Construction Overview】 ■ Location: Kitakyushu City, Fukuoka Prefecture ■ Roof Material: Wooden house ■ Area: Approximately 100m2 (attic of the second floor) ■ Materials ・ Prox heat insulation sheet (PRX-FN) ・ Stand light / Cutter ・ Protective sheets, etc. *For more details, please refer to the PDF document or feel free to contact us.

In the detached house F, there was a problem where the air conditioning was ineffective due to radiant heat from the attic, despite having insulation. To address this, we carried out heat insulation work in the ceiling to reduce radiant heat from outside and improve the air conditioning efficiency. Additionally, since there is attic storage in the ceiling that becomes quite hot, we also worked on that area. 【Construction Overview】 ■ Location: Kitakyushu City, Fukuoka Prefecture ■ Roof Material: Wooden house ■ Area: Approximately 80m2 (attic space on the second floor) ■ Materials - Prox thermal insulation sheet (PRX-FN) - Tacker/stand light/cutter - Protective sheets, etc. *For more details, please refer to the PDF document or feel free to contact us.
