What are the benefits of polycarbonate roofing?


When it comes to polycarbonate roofing sheets there are a range of useful benefits, including:

  • Polycarbonate roof panels are 290x stronger and less than half the weight of glass - which makes them much safer and  easier to handle. 

  • They also provide excellent security against hailstones, vandalism and accidental damage. 

  • With high levels of UV protection, harmful UV solar radiation is blocked by up to 98%. 

  • The clear multiwall and twinwall polycarbonate roofing sheets offer excellent light transmission - with 68% of natural light flooding into your room, creating a bright, spacious environment. 

  • Polycarbonate roof panels are self-extinguishing (up to “Class 1” fire rating). This means that they will melt away from the flames, making them much safer..  

  • Twinwall and multiwall polycarbonate roofing sheets also provide superb thermal performance and enhanced spanning capabilities. 

  • Polycarbonate roof panels are therefore a much more cost-effective choice than glass.

What is a twinwall polycarbonate sheet?


A twinwall polycarbonate sheet is made up of two exterior plastic sheets connected with a plastic support layer to create hollow parallel channels. 

This makes for a super-strong yet very lightweight plastic material that’s incredibly versatile. 

Multiwall polycarbonate sheets follow the same principle, but are made up of more hollow partitions. It’s a multi-layer structure that still retains good levels of light transmission.

The various layers that twinwall and multiwall polycarbonate sheeting is made up from provides superb thermal insulation, as well as relatively good sound insulation.

The type you choose is entirely up to you - but both types of polycarbonate sheet work extremely well as roofing solutions. 

Choosing your roofing sheets

Twinwall and multiwall polycarbonate sheets are the most popular polycarbonate commonly used for conservatories and lean-to roofs, walkways and swimming pools. When choosing your polycarbonate roofing sheets, there are a couple of things you need to consider besides size.


You’ll see on our solid polycarbonate and twinwall and multiwall polycarbonate sheets pages that there are a wide range of thicknesses that can be selected across the various cut to size options.

Essentially, the thicker the polycarbonate sheet, the stronger and more rigid the material is. This improves impact resistance amongst other things, and means your polycarbonate panels are robust enough to withstand whatever mother nature throws at it.


In addition to the crystal clear polycarbonate roofing sheets we supply, you can also purchase opal and bronze twin and multiwall polycarbonate sheets.

They offer the same spanning strength and shatterproof properties as the transparent sheets. However, many people choose these colours from a decorative standpoint - to provide a tinted effect for the panel when the roof comes into contact with sunlight.

Regardless of what polycarbonate roofing option you choose, just know that we’re here to help. It doesn’t matter whether you’re a professional tradesman, just starting a DIY job, adding the finishing touches to a roofing structure with the appropriate glazing bars, or just looking to keep things simple with a ready to fit carport or patio cover kit.
