C3 Fillet Corner Internal

The C3 Fillet Corner Internal is the companion piece to the C3 External, providing a pre-moulded GRP corner to complete the internal corner junction where two runs of D-series fillet trim meet - typically at an internal corner of a parapet wall, raised upstand, or roof abutment.

Internal corners are among the most difficult flat roof details to finish neatly using linear trim sections alone. The C3 internal corner eliminates the need to cut and fit two trim ends at an internal 90°, replacing the awkward junction with a single factory-moulded component that accurately matches the fillet profile and provides a continuously weathertight transition. Supplied in light grey GRP; fixed with PU adhesive to match the linear D-series trims.

A complete range of trims designed for use with glassfibre, polymeric, single membrane and liquid applied flat roofing systems. High adhesion light grey finish suitable for flatroofing, pitched roofing, domestic and industrial applications. Supplied in 3 metre or 1.5 metre lengths. Brochure and method data available on request. PU adhesive is required for installation.

GRP roofing trims provide a practical, durable, and aesthetically pleasing solution for finishing fibreglass flat roofs and for other domestic and industrial applications. With their superior strength, resistance to the elements, and ease of installation, they help ensure a long-lasting, weather-tight roofing system. By combining functionality with modern design, GRP trims offer an excellent way to enhance the performance and appearance of fibreglass roofs.
