Atlas Flat Rooflights create a modern and contemporary finish in extensions and flat roofs to give a more open feel to a space and let more light in. The natural daylight offered to rooms by Atlas Flat Rooflights is encouraged by minimal internal and external visible frame. Aluminium capping internally and externally provides a secure and strong flat rooflight alongside a bespoke PVCu internal core. A PVCu internal core is bridged with 28mm thick glass unit, comprising double-glazing between a 16mm argon gas cavity to provide thermal values of 1.3 W/m2K. The self-cleaning glass can be upgraded to Solar Neutral low maintenance low e glass by contacting us on 01752 692 760. Frames come in 1 of 3 colours as standard: black, white and grey. These are available in non-standard colours however by contacting our customer service team on 01752 692 760. There’s no upstand supplied with this Atlas Flat Rooflight so an 80mm thick upstand must be constructed. Atlas Flat Rooflights are easy to install however as they can be screwed from the side with hidden direct fixings. An internal plasterboard pocket can be found on these rooflights to make boarding and plastering even easier and quicker. Please note: All rooflight sizes given are internal kerb size.
