Zenon Archlight rooflights are manufactured and supplied as individual pre-curved self-supporting rooflight sheets characterised by a trapezoidal ribbed profile following the curve of the sheet. They are available for daylight openings or support systems up to 4 metres wide and at a fixed sheet radius of 3150mm in natural translucent or opal tinted
GRP and at a nominal weight of 2.4kg/m².
They are available to suit any length of construction or opening, and are easily installed in single, double or triple skin configurations using spacer brackets depending upon the thermal performance required, or in combination with flat profiled liners and insulation layers in built-up self-supporting metal sheet roofing systems. Subject to specification, they offer expected periods of non-fragility up to 25 years subject to all other elements of the assembly or roof construction retaining their integrity for the same period.
