C4 Universal Internal Corner

The C4 Universal Internal Corner is the internal-angle counterpart to the C1, providing a pre-moulded GRP corner for situations where two trim runs meet at an internal 90° - typically where a raised edge trim turns into a wall or parapet return. As with all corner pieces in this range, using the C4 instead of mitring trim on site removes a common point of weakness in flat roof detailing and gives a consistently neat result.

The universal profile is compatible with several standard linear trim ranges. Supplied in light grey GRP and fixed using PU adhesive. For compatible trims, see A200 and B260.

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. 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.
