Polycarbonate rooflight panel — LEXAN Thermoroof, 20 mm + 45 mm rib

Light coming through the roof reaches places where wall windows cannot solve a dark interior. Rooflights for sandwich panels bring this advantage to industrial buildings, warehouses and workshops. Properly arranged daylight strips make space deep inside the building more usable. During bright daytime conditions, they may also reduce reliance on artificial lighting, combining everyday comfort with an operational benefit.

Polycarbonate combines light transmission with low weight and impact resistance. This makes it suitable for lightweight roofing elements that admit light without the weight typical of comparable glass solutions. Multiwall construction improves insulation compared with a single plastic layer. In an insulated hall, this allows daylighting that better suits the building’s function than a basic thin transparent sheet. Low weight is also helpful in refurbishment, where additional daylighting must suit the capacity of the existing structure.

In products intended for outdoor use, a UV-protective layer helps retain the properties of material exposed to sunlight. A shape matched to the roof profile makes it easier to integrate the rooflight into sandwich panel roofing. This creates an orderly roof detail and may require fewer unusual connections than an assortment of unrelated components. It is useful both in a new building and when adding planned daylighting to an existing hall.

Daylighting from above leaves more freedom to use the walls. They can accommodate racks, process lines or displays instead of making light depend entirely on side windows. This is particularly useful in a wide warehouse or a room divided into workstations. Planned rooflight strips bring daylight close to the places where it is needed and improve the functionality of space already under the roof.

A bright interior makes workshop activities, order picking and finding your way around easier. In cost terms, there is value in reducing lamp operating time when daylight provides adequate illumination. Selecting the rooflight area combines that benefit with thermal requirements and building use. A properly planned system makes use of natural light without occupying more land or enlarging the building volume. Light-diffusing variants help distribute light more softly, which can be useful for workstations beneath the roof.
