Energy-saving and power-saving window insulation and heat-shielding sheets that do not easily darken the room.
Bright Barrier Petit
A heat-insulating and thermal-insulating sheet (Bright Barrier Petit) that can be applied to windows to combat heat and cold.
By applying Bright Barrier Puchi to the inside of the window, you can keep your space "cool in summer" and "warm in winter" (insulation and heat shielding). Thanks to its light-transmitting properties, the room does not easily become dark, which enhances heating and cooling efficiency, leading to energy conservation and reduced electricity usage. Heat shielding: By reflecting infrared rays, it suppresses the rise in room temperature. Insulation: The air layer of the bubble wrap (Puchipuchi®) prevents cold air from entering and retains warm air, thereby reducing condensation.
