Polycarbonate Roofs Vs GRP Roofs

Polycarbonate Roofs Vs GRP Roofs

The Coniston Wall Mounted Canopy with 35mm Structured Polycarbonate Roof PanelsWhen it comes to choosing a canopy, the type, shape and colours are not the only important factors to take into consideration, you also need to think about the construction materials used such as the roof panels. The roof panels are important as these cover your canopy and people underneath. You need roof panels that will perform overtime with the unpredictable climatic conditions that we experience in the UK.

It can be hard to know what material would be best just by looking at the appearance or by going on what you have heard so that’s’ why a simple and to the point comparison list of the advantages and disadvantages of each will help you. And guess what… I’ve created that exact comparison list so you can save time and discover the perfect roof material for your future canopy!

GRP Roof Panels

GRP stands for Glass Reinforced Plastic and is also known as FRP (Fibre Reinforced Plastic). It is a composite laminate of glass fibres mixed in with polyester resin.


  • Versatile
  • Similar Appearance to Glass
  • Choice of Colours – Can be translucent, opaque or many other colours
  • Available with UV Stabiliser – Available covered with a UV stabilised layer to provide UV protection


  • Panels Discolour – Sunlight can cause the clear GRP panels to discolour & cause coloured panels to fade & deteriorate
  • Low Impact Resistance – It has a lower impact resistance than Polycarbonate
  • Shorter Life Expectancy – The life span of GRP is shorter compared to other roof panel materials – approx 10 years
  • Rough & Difficult to Clean Surface – The surface of this material is often rough therefore making it difficult to clean and needs more maintenance than other roofing materials.

Polycarbonate Roof Panels

Polycarbonate is a light weight, strong material that is used for a wide variety of applications from bulletproof windows & shields to CD’s and eye glasses and it is nearly unbreakable. What makes this material stand out from similar materials is its superior light weight to high strength ratio making it a first choice for many applications.


  • High Impact Resistance – Has a very high impact resistance, making it virtually unbreakable
  • Versatile – Polycarbonate is used for many applications such as CD’s, eyeglass lenses, bullet proof windows, conservatory roofs and canopy roofs
  • Choice of Colours – Can be translucent, opaque or bronze
  • Long Life Span – It has a 25 year life expectancy
  • High UV Protection – Many varieties are co-extruded (manufactured) with a UV filter to offer high UV protection to those underneath.
  • Cost Effective – It’s cost effective compared to other glazing options
  • Durable and Tough – This is a strong material that has an excellent structural performance
  • Long Lasting – Maintains its high strength and clean look over time
  • Excellent Fire Performance – It is self-extinguishing when the source of the flame is removed and it will not promote fire or assist the spread of fire
  • Low Heat Transmission – Keeps the area underneath cool in hot, sunny weather
  • Effective resistance to weather
  • Readily Recyclable
