Solar Control Glass – Clarity and Comfort Combined
Enjoy clear, bright views while maintaining a comfortable indoor environment. Rooflight Factory solar control glass combines low-emissivity inner glass with argon gas filling, reducing solar heat transmission by up to 50% compared to ordinary double glazing. It helps retain warmth in winter, reduce glare in summer, and cut energy costs — creating the perfect balance of light and comfort.
Self-Cleaning Glass – Effortless Maintenance
Spend less time cleaning with Rooflight Factory self-cleaning glass technology. Activated by UV light and rainwater, it naturally breaks down and washes away dirt, dust, and organic build-up. This intelligent coating keeps your lantern clear and bright with minimal maintenance, saving you time and effort.
