They can be specified with advanced glass options too, including solar control and self-cleaning coatings, for year-round comfort and low maintenance.
Meanwhile, the glazed flat rooflight sits flush with your plaster for a clean, frameless appearance.

Glass Types
Our Flat Glass Rooflights can be specified with a range of high-performance glazing options to suit your space and lifestyle. From managing solar gain to reducing ongoing maintenance, each glass type is designed to enhance daylight while improving year-round performance.
Solar Control Glass
Uses special coatings or tints to reflect and filter the sun’s heat (infrared radiation) while letting in natural daylight, keeping buildings cooler in summer, reducing glare, cutting air conditioning costs.
Self-Cleaning Glass
Has a special transparent coating (usually titanium dioxide) that uses UV light from the sun to break down organic dirt and grime, and then uses rain (or water) to wash it away, leaving fewer streaks due to its hydrophilic (water-spreading) properties.
