Roof skylights are particularly suitable for some types of production halls, warehouses, shops. However, they are not suitable for sports halls, production halls where the sun could glare. For warehouses with racking systems, the skylight must be mounted across to the racking.

The possible pros and cons of this type of lighting need to be considered.

Main advantages of rooflights:

• Lower energy consumption for hall lighting
• Efficient lighting of the hall interior
• Natural and pleasant daylight illumination
• Ensuring natural, realistic colours in the interior
• Natural light reduces feelings of drowsiness, fatigue, depression and improves concentration and mood
• Efficient ventilation through openings
• Maintenance-free

Disadvantages of skylights:

• Heat leakage from the hall
• Skylights are not suitable for areas where sunlight is not desired (welding, sports)
• Interference with the roof sheathing can lead to possible leakage into the hall during rain
• Creation of unwanted shadows in the hall and uneven lighting in the hall

Which type of skylight to choose for an industrial hall

If you decide to light your hall with a rooflight, there are several types of rooflights to choose from.

The most popular types of skylights for prefabricated halls include:

• Roof ridge skylights
• Roof point skylights
• Skylight panels

Roof ridge skylights

Roof ridge skylights are placed in the ridge of the hall along the entire length of the roof or only partially according to the needs of the investor. Most commonly, the rooflights are supplied in 3m widths and are suitable for snow areas up to 4 kN/m2.

The skylights are usually supplied with an opening for efficient and easy ventilation in the hall and an electric servo motor and a rain and wind sensor to ensure that the ventilation sash closes immediately in the event of rain.

The skylight is installed on a galvanised sheet metal frame. The aluminium structure of the skylight is sheathed with 16mm thick polycarbonate plates in opal colour with thermal properties U=1.84 W/m2K and UV protection layer. We also supply skylights with 25mm thick polycarbonate boards with better thermal properties U=1.45 W/m2K.

Point skylights

Point skylights are suitable for both flat roofs and roofs with a slight slope. They are suitable for lighting kitchens, warehouses, toilets, staircases and especially the middle rooms in the hall where it is not possible to provide daylight through windows.

Spotlights can be supplied with or without an opening. Skylights with an opening serve as a low-cost natural ventilation element, which ensures cost savings on expensive air conditioning equipment. The opener can be designed with an electric motor or manual solution.

Illuminating panels

Skylight panels are a cheaper solution for roof lighting than skylights, provide plenty of daylight, are easy to install and come in the same profile as the roof panel. They are suitable for roof pitches of at least 4°.

The panels are made of polycarbonate with thermal properties U=2.0 W/m2K. The light transmittance of these panels is 63%. The panels are supplied in lengths of 1-8 metres.
