It is important to keep in mind that your polycarbonate roofing sheets need to fit between your roof joists, so you need to take some careful measurements to ensure that you’ve purchased the correct size. In this article, we have provided a basic guide that we hope will help you to choose the most appropriate sheets for your application. If you’re having any problems making a selection, ensure that you speak further with your supplier.
Getting the Right Size
You have two choices when it comes to getting polycarbonate of the correct size for your application. Firstly, you could purchase sheets and cut them down to size yourself. Despite the material’s impressive strength, it is actually fairly easy to cut through yourself using a fine-toothed saw. Secondly, you could by sheets at the size you require. This might take a little more searching or compromise, particularly if you require an unusual size.
Getting the Right Shape
In addition, polycarbonate roofing sheets can also be cut into any shape, which makes them suitable for many different styles of roof. Some of these styles include gable (where two roofs come together to form a point), lean-to (typically a roof with a single slope), Edwardian and Georgian. The sheets are also suitable for canopies, which are usually supported by your house and by two (or more) support posts). If you require a special shape, ensure you mention this.
Getting the Right Thickness
There are also a number of different thicknesses available for polycarbonate, each suiting different purposes. Whilst some people are happy to just use whatever thickness they can get their hands on, it can be beneficial to consider your application. Even the thinnest option should be able to withstand most of the wear and tear exerted on it, otherwise it would not be deemed acceptable for outside use. Some of the more popular choices include.
- 4mm: This is great for greenhouses, cold frames and sheds.
- 10mm: This is great for carports, pergolas and sheds.
- 25mm/35mm: This is great for conservatories.
When your polycarbonate arrives, it should be covered with a protective film to help prevent scratches and other damage. This should be left in place until the sheet has been fitted. The top and bottom ends should also be capped when the sheet is whole. If you’re cutting the material down to size, try to keep the top end capping in place and cover the cut end with some perforated self-adhesive tape. A plastic cover bead can be fitted over the tape to cap the end.
We hope that the information provided above has helped you to select polycarbonate roofing sheets that are appropriate for your application. Another important point to keep in mind is that you need to prevent moisture from entering the flutes in your polycarbonate and, if you need to store the sheets prior to fitting them, ensure that you have chosen a dry location (so, not outside or on wet grass). This will help them to retain their integrity.
