Ministry of Health, Labour and Welfare: Heatstroke measures with the metal standing seam roof heat insulation sheet "Cool Roof".

A heat insulation and thermal insulation system for metal standing seam roofs that utilizes the effects of "shade." Low-cost and short-term construction, with a 5-year performance guarantee and annual inspections during the warranty period.

The Cool Roof is a heat insulation and thermal insulation system developed for metal corrugated roofs commonly used in factories and warehouses. It is effective in summer for heat shielding and in winter for building insulation and condensation prevention. It contributes to energy savings throughout the year. 【Features】 ★ Reduces rain noise and sound resonance. The Cool Roof acts as a cushion, reducing the sound of rain and hail. ★ Blocks sunlight with a sheet, preventing temperature rise across the entire roof. ★ The space (air layer) between the sheet and the roof prevents heat transfer. ★ Wind passes through the sheet holes and air layer, allowing warm air to escape. ★ The heat shielding effect in the summer under direct sunlight shows a temperature difference of nearly 30°C between the installed and uninstalled areas of single corrugated roofs (demonstrated measurement results). ★ Mitigates room temperature rise, significantly reducing air conditioning costs and contributing to energy savings. ★ In winter, it prevents warm air from escaping, demonstrating insulation effectiveness. ★ The Cool Roof can also suppress condensation by reducing radiative cooling. ★ Additionally, it has noise reduction effects and protects roofing materials. ★ It comes with a 5-year performance guarantee, with annual inspections during this period. ★ Installation for 1,000 square meters takes about one day, resulting in a short construction period.
