Effect of cool roofs on reducing rain noise

Contributes to the protection of the roof surface! The rooftop natural energy application heat-insulating sheet reduces the sound of rain hitting metal roofs.

The data measuring 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 "Chill Roof," the sound of rain hitting the metal roof is reduced when it encounters 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 fasteners and joints connecting the roof to the building to creak and produce noise. By installing our product, the entire roof is covered in shade, allowing for temperature equalization of the roof, which can suppress noise caused by thermal expansion. *For more details, please refer to the PDF document or feel free to contact us.
