Product Information
Full details
The Corotherm Side Flashing is designed for professional builders and DIY enthusiasts working with 16mm polycarbonate roofing systems who need a durable, weather-tight edge finish. It serves as an essential component for covering end rafters to prevent water ingress while providing a clean, aesthetic look to the roofline. While it offers excellent protection, users should note that it is specifically engineered for 16mm sheets and requires careful measurement to ensure a flush fit with the existing glazing bars.

FAQs
Is this flashing suitable for 25mm sheets?
No, this specific model is designed exclusively for 16mm polycarbonate sheets.
Can I paint the white PVC?
It is not recommended, as PVC requires specific plastic-bonding paints, and the factory-applied finish is designed to be low-maintenance.
Does this come with fixing screws?
Fixing screws are generally sold separately as they depend on the material of your rafter structure (timber or metal).
How do I cut the flashing?
A standard fine-toothed handsaw or a power mitre saw with a plastic-cutting blade works best.
Can it be used on curved roofs?
No, this product is intended for straight, linear roof edges and cannot be bent to accommodate curves.
Is it UV resistant?
Yes, it is made from durable PVC formulated to withstand long-term outdoor UV exposure without becoming brittle.
Troubleshooting
Flashing does not sit flush against the rafter
Check for debris under the flashing or ensure the end rafter is perfectly level and square with the roof structure.
Water leaking at the edge
Ensure a bead of neutral-cure silicone has been applied to the mating surfaces and check that screws are tightened sufficiently to compress the seal.

Setup, Compatibility & Care
To install, ensure your end rafter is level and clear of debris. Measure the required length and cut the PVC flashing using a fine-toothed saw. Position the flashing over the end of the sheet and the rafter, securing it according to your specific framing configuration. For optimal weather protection, apply a small bead of neutral-cure silicone along the contact edge before fixing. For care, simply clean the surface annually with warm soapy water and a soft cloth to remove grime and prevent algae buildup. Avoid abrasive cleaners or strong solvents that could scratch or damage the PVC surface.
