If you’re planning a pergola or outdoor roof, you’ve probably run into a few of the same questions most people have. This page covers the ones we hear every day, with straightforward answers to help you choose the right setup.
What types of polycarbonate roofing sheets are available?
At Polyguru, we supply a range of polycarbonate sheets suited for outdoor roofing in Australian conditions.
The most common options include:

How do I choose the right polycarbonate sheet?
This depends on how you want your outdoor space to feel and function.
A few things to think about:
- How much natural light you want
- Whether heat reduction is important
- The overall look you’re going for
Clear sheets let in more light. Tinted or diffused options help reduce glare and heat. The right choice usually comes down to how you plan to use the space day to day.
Can I get polycarbonate roofing samples?
Yes, and it’s worth doing before you decide.
Seeing the sheets in person makes it easier to compare colours, finishes, and how much light they let through.

Are polycarbonate sheets suitable for DIY installation?
In many cases, yes.
Products like EZ Glaze are designed to be installed by homeowners or with the help of a builder. The sheets are lightweight and relatively easy to handle.
Before starting, it’s important to check the structure, support spacing, and drainage. If you’re unsure about any part of the setup, it’s better to ask first.
Do polycarbonate sheets expand with heat?
Yes, and this is something people often miss.
Polycarbonate expands and contracts with temperature changes. If it’s fixed too tightly, it can cause stress on the sheets or fasteners.
A common approach is to allow around 10mm clearance for expansion when drilling fixing holes.
How long does a polycarbonate roof last?
With proper installation and a quality product, polycarbonate roofing can last for many years.
The sheets are designed to handle UV exposure, rain, and general outdoor conditions, which makes them a reliable option for pergolas and patios.
What’s the difference between clear, tinted, and diffused sheets?
Each option changes how the space feels.
- Clear – more light, brighter space
- Tinted – less glare and reduced heat
- Diffused (like Sunpal) – softer light, more even coverage
If your pergola gets a lot of direct sun, this choice will affect comfort more than you might expect.
What if I’m still not sure which option to choose?
That’s pretty common.
Every project is a bit different, and a quick conversation can usually point you in the right direction. It’s easier to make the right call early than change things later.
