The White Fascia External 135° Corner (300mm) is a precision-moulded uPVC trim designed for clean, professional transitions at angled roofline junctions—especially around bay windows and conservatories. Its 135-degree profile ensures a seamless connection between fascia boards at non-standard external angles. Manufactured from UV-stabilized, lead-free uPVC, it resists warping, fading, and impact damage. Compatible with square-edge and capping fascia systems, this corner piece simplifies installation and enhances the overall aesthetic of any roofline project.
