Composition 

The double glazed glass panel is made up of: 6mm toughened outer, a 90% argon filled cavity, with a 9.5mm laminated soft coat Low E inner (inc. 1.5mm PVB interlayer). For larger sizes the inner pane thickness is increased to 11.5mm.

The frame is extruded aluminium, with a powder coating (RAL 7016) to provide a premium appearance and highly appealing finish. The rooflight assembly is thermally broken to provide excellent thermal performance.
