Summary

As you can see, there are so many polycarbonate sheets to choose from. Whether it is super-thick sheets that work perfectly as glass replacements in windows, or thinner sheets that can operate on a multi-use basis, we have got you covered. We do understand, however, that some of you may be reading this completely bewildered by which polycarbonate sheet would be the best for you. We have listed a few things for you to consider below, as well as a detailed FAQ to answer any burning questions that you may have. You may be interested in other guides on the best:

Thickness

It’s important to consider the thickness of your polycarbonate sheets, as this will ultimately influence how flexible they can be, as well as how easy they’ll be to cut and shape to your desired look. The thicker the sheet, the less flexible it will be. Similar to bird netting and other size-sensitive products, you want to check the thickness in comparison to where your sheets will be going.

Colour

There are a number of different colours available, with the most common being, well – completely clear! The coloured sheets are usually more suitable if you want a tint in your windows, or you are using the sheets for a cold wall where they won’t be used as a light source, instead, a heat/air source. For this, you do not have to be precious with the colour you pick. However, if you plan to use your sheets for windows (whether that is a shed or a greenhouse), we recommend going for clear, or something with a very light tint.

UV protection

If you are planning to use your sheets as windows or even as a ceiling (in a greenhouse) then it is imperative that you buy sheets that have UV protection. This will not just extend the lifespan of your sheets, but will also protect you from the suns harsh rays. It is important to note that over time your sheets may start to discolour, however investing in UV protection will help you to prolong this.

FAQ

What thickness polycarbonate should I use?

It completely depends on what you plan to use it for. If you are looking to use polycarbonate for your windows, you can opt for a thickness upwards of 3mm with a maximum of probably 8-10 mm. The thicker the sheet, the more expensive it will be, but also, the heavier it will be. If you plan for these windows to open on a hinge you need to be conscious of this. Once you have that covered, you can grab some shed felt, a nice chair and you are good to go.

What are the disadvantages of polycarbonate?

The biggest disadvantage is the price. Although there are a lot of affordable options on the market, we are not oblivious to the fact that polycarbonate sheets are notoriously more expensive than glass, acrylic or other materials. However, polycarbonate is incredibly durable and long-wearing.

Why does polycarbonate turn yellow?

Due to continuous sun exposure, some polycarbonate can turn yellow quicker than others. It also depends on how sunny your climate is, too. We always recommend, especially if you plan to have a completely polycarbonate greenhouse, that you invest in polycarbonate that is treated with a UV layer, to avoid discolouration, whether that is prevention or prolonging the life of your polycarbonate.

What is the difference between acrylic and polycarbonate?

We have inserted a video below which explains with clarity the difference between acrylic and polycarbonate.
