What Are the Benefits of Using Polycarbonate Roofing Sheets?

Polycarbonate and similar materials, like plexiglass, have seen a spike in popularity in recent months. This is no doubt due to the pandemic.

But what is polycarbonate and why is it beneficial? Is it only for industrial or commercial use? 

Polycarbonate roofing sheets are a type of thermoplastic that are lightweight and durable. They're often used in conservatory roofing, greenhouses, and sheds as an alternative to glass panels. As they're highly sustainable, you can re-grind the sheets or recycle them for other purposes.

They won't warp or become discolored in the heat, either. This makes polycarbonate a great option for your next outdoor project. 

Key features

Polycarbonate roofing sheets have excellent impact resistance and retain heat. This means it's ideal for greenhouses and other rooms you'd like to keep warm. As it's also shatter-resistant, you'll get years more use out of your polycarbonate.

Similarly, polycarbonate offers a good defense against vandalism, inclement weather, and even fire. Some polycarbonate is even self-extinguishing. It's a lightweight, lower-cost alternative to glass.    

Benefits over glass

The main benefit of using polycarbonate over glass is that you don't have to worry about it breaking. Beyond that, you can transport polycarbonate more easily, and it's much lighter. 

Glass is 100% transparent and polycarbonate only 70-90%. That means glass requires more cleaning to keep it clear and shining. Glass is also prone to scratching, whereas polycarbonate is not.

Types of Polycarbonate 

There is a wide range of polycarbonate sheets from which to choose. But how do you pick the best? We've detailed the top three varieties below and how to use them most effectively.

Solid Polycarbonate Sheets

Solid sheets of polycarbonate are just what you'd think: one solid layer of material. This makes it an excellent choice for greenhouses or conservatories. It lets in enough light but not so much that it's blinding to you or damaging to your plants. 

These sheets come in standard sizes around 4mm polycarbonate to 12mm. Thus, it may be difficult to have your sheets cut to size.

Multiwall Polycarbonate

As you'd expect, multiwall polycarbonate sheets have multiple layers. Shorter pieces of polycarbonate run perpendicularly between each layer. They hold the wider sheets of polycarbonate away from each other, leaving gaps.

These sheets provide the perfect insulation for a greenhouse or sunroom. Cut them to size or pick up a standard sheet up to 35mm thick.

Corrugated Polycarbonate

Corrugated polycarbonate is ideal for smaller projects. It comes in thinner sheets and is cheaper than solid or multi-wall polycarbonate. When you consider using this variety for roofing, 4mm polycarbonate is not recommended.

Using Polycarbonate Roofing Sheets

Polycarbonate roofing sheets are a cost-effective way to complete your next outdoor project. Whether you're building a backyard greenhouse or making a lean-to-shed, consider polycarbonate.
