LEXAN Thermoroof rooflight for sandwich panels — 20 mm + 45 mm rib

In a wide workshop, the darkest areas are often far from wall windows. Rooflights for sandwich panels bring daylight directly above that part of the interior. The polycarbonate daylighting becomes part of the roof surface, allowing a heated hall to combine an insulated envelope with a brighter working space.

Light entering from above helps make better use of a deep room. It can illuminate a circulation route, an order-picking zone or space between racks. Walls remain available for equipment, doors and storage. This is useful where the building plan is driven primarily by production or warehousing needs. The arrangement of translucent areas connects lighting to the function of each part of the hall.

The cellular structure of polycarbonate combines light transmission with reduced heat flow. Voids within the sheet form a lightweight insulating arrangement, relevant to a sandwich panel envelope. This type of rooflight can provide daylight to heated rooms, with its performance selected for the planned envelope. In a workshop, visibility and thermal conditions can therefore be considered together, with translucent areas designed as part of the insulated building fabric.

Profiled daylighting products such as LEXAN Thermoroof are designed for use with particular sandwich roof panels. Their matching shape helps integrate translucent areas into the roof’s regular pattern. System seals, spacers and fixings assist in detailing the joints. Together they create a well-finished roof section in which neighbouring materials have compatible geometry, benefiting both appearance and weather protection.

Polycarbonate is lightweight and has good impact resistance. This is valuable for translucent elements in large roofs, where infill weight affects the overall structural solution. A UV-protective layer protects the appropriate product during sunlight exposure. A lightweight sheet is also easier to move and position. Combined with profiling, these properties provide a material intended for use high above the occupied space.

A brighter interior is more pleasant in everyday use and makes orientation easier. Under suitable daylight conditions and with lighting controls, it can reduce the need to use some lamps. The effect depends on the daylighting area, weather and work organisation, so light fields should be planned together with the equipment layout. In a new hall or a roof refurbishment, this brings natural light precisely where it can provide practical benefit.
