View product details →ERUMI KOREA's high-end window film, crafted with precision multilayer sputtering.
A premium solution that combines solar heat reflection and refined optical properties with building energy efficiency and architectural quality in mind.
Efficient window film combining strong sunlight control, privacy and value
ERUMI NSN15 uses precision multilayer sputtering for high solar energy rejection and heat reflection. Its deep, refined color reduces strong sunlight and glare while considering privacy and architectural appearance.
Premium homes, large glazed buildings, offices, commercial premises, public institutions and spaces requiring privacy
THE NSN DIFFERENCE
01
Silver (Ag) and nickel-chromium (NiCr) are deposited in multiple layers. Precision multilayer sputtering combines different metal layers with heat reflection and optical performance in mind.
