Are there any concerns among those using buildings with metal standing seam roofs, such as wanting to "heat efficiently" in winter, "reduce condensation," or dealing with "heat in the building" and "lower utility costs" in summer? Our rooftop natural energy application heat insulation sheet, 'Chill Roof,' is effective year-round for summer heat insulation, winter heat retention, and condensation prevention. It has low initial installation costs and does not suffer from reduced effectiveness due to dirt. It is removable, making it suitable for temporary and rental properties, and all materials are recyclable after removal. 【Features】 ■ Low Cost - Affordable initial installation costs - Effective with installation on about 80% of the roof area ■ Short Installation Time - Approximately 1 day for 1000m2 - Can be installed without damaging the roof ■ Maintenance Cost: 0 yen *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the mechanism of our rooftop natural energy application heat-insulating sheet, "Hie Roof." The product installed on top of the corrugated roof creates shade, suppressing the temperature rise of the corrugated panels. Since the heat insulation is achieved through the effect of shade, it is not affected by dirt on the roof and continues to exhibit its heat-insulating effect. Additionally, the sound of rain or hail hitting the corrugated roof is mitigated, and in winter, the radiation cooling from the roof surface is reduced, making it harder for the heat accumulated inside to escape, thereby enhancing the building's insulation effect. Furthermore, the airflow between the sheet and the corrugated roof prevents heat buildup beneath the sheet, enhancing the insulation effect of our product. 【Effects】 ■Temperature reduction ■Energy saving ■CO2 reduction ■Reduction of rain noise *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the temperature reduction effect of our rooftop natural energy application heat insulation sheet, "Chill Roof." In a thermal imaging test of the heat insulation performance in the attic, the temperature in the uninstalled area was 48.0°C, while the temperature in the installed area was 37.5°C, resulting in a temperature difference of -10.5°C. Thanks to the effectiveness of this product, sunlight is blocked, creating shade on the roof and suppressing the rise in roof temperature. This helps to stop excessive air conditioning operation, leading to a reduction in electricity costs and contributing to energy conservation. [Thermal Imaging Test of Attic Heat Insulation Performance] ■ Attic Temperature (Uninstalled): 48.0°C ■ Attic Temperature (Installed): 37.5°C ■ Temperature Difference: -10.5°C *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the insulation effect of our rooftop natural energy application heat insulation sheet, "Chill Roof." This product helps to equalize the surface temperature of the roof, showing a decrease in temperature during sunlight hours. However, during nighttime or other periods without sunlight, it has been confirmed that the roof surface temperature remains higher compared to when it has not been applied. During snowfall, the difference in effectiveness becomes even more apparent. While the roof surface continues to be cooled by the snow, the snow does not remain between the sheet and the corrugated panel, allowing the air layer to provide additional insulation. In the PDF materials, we provide detailed information using photos and diagrams. Please take a look. *For more details, please refer to the PDF materials or feel free to contact us.*

The measured data of the noise from rain and hail hitting the roof directly shows that rain is -7 to 9 dB, and hail is -15 to 16 dB. By using the rooftop natural force application heat insulation sheet "Cool Roof," the noise from rain hitting the metal roof is reduced when it receives rain or hail. Additionally, standing seam roofs create shaded areas depending on the position of sunlight, which also changes the surface temperature. This results in different rates of thermal expansion on the roof, causing the metal fittings and fastening parts that connect the roof to the building to creak and produce noise. By installing our product, the entire roof is covered in shade, allowing for temperature leveling of the roof and suppressing noise caused by thermal expansion. *For more details, please refer to the PDF materials or feel free to contact us.

We will introduce a comparison between our rooftop natural energy application heat-insulating sheet "Hie Roof" and other heat-insulating methods. In terms of installation area, while heat-insulating paint requires more than 150% of the roof area and rooftop greening can only be installed with less than the roof area, our product can be installed with about 80% or less of the roof area. The construction period for 1000m² is approximately 1 day for the interlocking type and 3 to 4 days for the overlapping type, and the insulation effect continues without decreasing. In the PDF materials, we provide a detailed comparison of appearance, maintenance costs, and sustainability of effects with other heat-insulating methods. Please feel free to download and take a look. *For more details, please refer to the PDF materials or feel free to contact us.
