What is Polycarbonate Roof Sheeting and What are its Advantages?

Polycarbonate roof sheeting is a plastic roof sheeting used mostly for deck areas, patios, greenhouses and conservatories.

Polycarbonate roof sheeting applications

It’s made from a strong, versatile thermoplastic material which is extremely impact resistant, easy to use, has a good fire rating, transmits a lot of light and can withstand extreme temperatures.

Polycarbonate plastic is a newer type of plastic which is becoming more widely used in the construction industry all over the world.

Types of polycarbonate roof sheeting

Solid Polycarbonate

Also known as flat or domed polycarbonate, this type of sheeting provides excellent workability as well as optical clarity.

Furthermore, it can be shaped (cold-curved) on site in order for it to properly fit its application. Mouldable shapes include domes and even pyramids.

Corrugated polycarbonate sheeting

The profile of this sheeting can be designed to match the profile of an existing roof cladding. MODEK polycarbonate comes in all the profiles used for standard cladding and roofing in South Africa.

Translucent polycarbonate sheets

Most commonly used for patios, sun rooms and other areas such as long passages that require large amounts of natural light to come through the roof.

These sheets come standard with a protective layer of film which filters out UV rays from the sun.

Foam-backed polycarbonate sheets

Mainly used for industrial buildings such as factories and warehouses. This type of roofing is lightweight and also widely used by homeowners to cover sheds, carports or other sloped roofs.
