Benefits of ERUMI window film
Enhancing
Everyday Life
Comfort, safety and energy savings.
Discover the difference ERUMI window films bring to everyday life.
UV PROTECTION
100% rejection of harmful UV
Fourth-generation HYBRID film developed through extensive trial and improvement. ERUMI KOREA insulating films are made in Korea using patented domestic technology.
Light meets glass, and its path changes
UV arrives with sunlight
Some light reflects from the glass surface; the rest passes through into the room.
Let light in, keep UV out
Preserve brightness and views beyond the glass while blocking harmful UV.
Patented nanotechnology insulating film
ERUMI window film blocks 100% of harmful UV when installed. Patented UV protection and insulating performance help protect indoor environments.

Blocking technology reaching approximately 410 nm
ERUMI window film provides 100% UV rejection up to approximately 410 nm. Some conventional window films labeled 99% UV rejection may only block to around 360 nm. Since remaining UVA can affect skin, eyes, furniture and interior colors, review the wavelength range as well as the rejection percentage.
