Polycarbonate Roofing Sheets

Benefits of These Polycarbonate Sheets

Light but Strong: These sheets are a feat of material science, mixing light weight with toughness. This quality makes them easy to install and cuts down on building weight, which matters a lot in today's building design. Take conservatories, for example where you want see-through and light materials; these sheets hit the sweet spot.

Top-notch Weather Protection: Structured sheets can handle all sorts of weather like nothing else. They're built to take on harsh sun heavy rain, and even snow, which means they last a long time.

Fire Safety: Unlike acrylic, polycarbonate sheets put themselves out if they catch fire.

Eco-friendly: Polycarbonate sheet not only last a long time, but you can also recycle them when you're done using them. 

The most popular thickness of multiwall is the 16mm sheets.

It is worth noting that 4mm and 6mm polycarbonate sheets are not recommended for roofing projects but rather as cost-effective plastic sheeting for smaller garden applications like cloches and cold frames.

Which polycarbonate sheet thickness should I purchase?

The ideal thickness of your sheet hinges on the intended use of the space it will cover. If you're constructing a canopy, carport, pergola, or any shelter primarily for protection from the elements, insulation value isn't a primary concern. In such cases, a 10mm thick sheet may suffice as it primarily serves as a protective barrier.

4mm: Ideal for cloches and temporary glazing; not suitable for roofing applications.

6mm: Well-suited for cold frames and greenhouses; not recommended for roofing.

10mm: Suitable for potting sheets and pergolas.

16mm: Ideal for lean-tos, gazeboes, canopies, and carports.

25mm: Perfect for lean-to extensions and garden buildings.

35mm: Recommended for conservatory roofs, orangeries, and extensions.
