Polycarbonate Sheeting - the Best Roofing Material for Natural Light

It’s very easy to argue that polycarbonate roof sheeting is by far the best roofing material for natural light applications.

Polycarbonate sheets are extremely versatile, making them a good choice for most roofing projects and are a great alternative to fibreglass and glass.

Polycarbonate Roof Sheeting (PRS)

PRS has many advantages over other roofing material options. This thermoplastic material is lightweight, flexible, extremely durable and mouldable.

It has a really high impact and fire resistance and maintains its shape, colour and transparency for many years.

However, one of its biggest advantages is its ability to transmit light, while offering the option of customising the transparency and in turn, the amount of light that is transmitted.

This is particularly useful, as some areas of your building may require 100% light transmission, while other areas may require less light, but still more than what fibreglass or other roofing materials can offer.

Furthermore, this material is far more durable than glass fiberglass roofing, making it the perfect roofing solution for most roofs and the best roofing material for natural light.

The Benefits of Natural Light

Ultimately, natural light is a greener solution to providing light. We don’t need to pay for the sun to shine, making natural light a free and very valuable, useful resource.

Depending on the type of building, polycarbonate roofing allows us to let in as much natural light that it needs, while still providing us with protection from the natural elements.

In this way, energy costs are drastically minimised as there is no need to use artificial light during the day.

Furthermore, natural light has many benefits regarding our health and well-being. Sunlight is an essential source of Vitamin D, which plays a major role in energy levels and the production of serotonin, our happy hormone.

Transmission of Heat and Light

There are 3 types of radiation from the sun that we are exposed to:

  • Visible light – helps us to see
  • Ultra Violet – harmful in high amounts
  • Near infrared – radiation that turns into heat when absorbed by objects

When using polycarbonate sheeting for natural light, one must take into consideration the amount of heat that will be transmitted.

The more light that is transmitted into the building, the more heat is retained. This is caused by infrared radiation from the sun that accumulates under the roof.

Fortunately, PRS provides the ability to add specialised colours which help with blocking out various forms of heat, radiation and light.

These tints are not to be confused with standard coloured sheets. These tints have the ability to allow minimal heat transmission with higher levels of light transmission.

The percentage of tinting additives can be adjusted according to the specific requirements of the building. This is particularly useful for different applications ranging from greenhouses to conservatories and indoor pool areas.

It’s important to note that most PRS comes with a standard layer of UV protection on the upside of each sheet, which protects the occupants of the building, as well as the sheet itself against, harmful UV rays.
