Solar Control Glass for Energy Efficiency
Transform the way light enters your home with Rooflight Factory solar control glass. This advanced glazing system uses a low-emissivity inner layer and argon gas filling to reduce solar heat transfer by up to 50% compared to standard double glazing. The result? Brighter rooms, reduced glare, and improved energy efficiency — keeping your home warmer in winter and cooler in summer.
Self-Cleaning Glass for Effortless Maintenance
Say goodbye to constant cleaning with our self-cleaning glass technology. Activated by natural UV light and rainwater, the glass surface breaks down and washes away dirt, dust, and organic build-up — leaving your roof lantern cleaner for longer. This intelligent solution saves time, effort, and maintenance costs over the long term.
