Composite External Corner Red Brown - Series 1

The Composite External Corner Red Brown – Series 1 trim is designed to give cladded external corners a finished, cohesive look that ties in perfectly with Series 1 slatted cladding panels. It covers cut panel ends at outside corners and provides a smooth, continuous junction that looks neat from every angle.

Offered in 2.5m and 3.6m lengths, this trim gives you flexibility to suit different wall heights and project requirements, helping to reduce waste and simplify planning. With an approximate width of 49.25mm including the lip, it offers sufficient coverage while maintaining a slim, elegant profile.

Made from durable composite material, the trim is engineered for long-term outdoor use. It is resistant to weather, insects and rot, and incorporates UV protection to help keep the Red Brown finish looking rich and consistent over time. The smooth surface complements the linear style of slatted cladding, delivering a smart, contemporary edge detail with a warm, timber-inspired tone.

The trim is easy to cut to size using standard woodworking tools and fits securely over timber or composite battens. To achieve the most accurate and visually pleasing result, it is often recommended that the external corner trims are installed before the main Series 1 panels, providing a reference line for the cladding to work up to.

For anyone seeking a robust, visually harmonious way to finish external corners, the Red Brown Series 1 composite external corner trim offers a practical, attractive solution that enhances and protects your cladding installation.

Start by ensuring that the external corner where the trim will be fitted is straight, plumb and supported by correctly installed battens or an appropriate substrate. Many installers prefer to fix corner trims before adding cladding panels, as this helps set out the lines for the rest of the installation.

Choose the most suitable length for your project, either 5m or 6m, and measure the height of the corner. Cut the trim to size with a fine-toothed saw designed for composite products, then position it on the corner to check the fit.

Fix the trim in place by pre-drilling through the faces into the battens and securing with suitable exterior-grade screws, or by applying a compatible outdoor adhesive where appropriate. Space fixings evenly along the length and avoid overtightening, which can distort the profile.

Once the external corner trim is secure, install the Series 1 slatted cladding panels so that their cut ends sit neatly behind the trim, forming a protected, concealed junction. Work up the wall, checking alignment frequently to maintain straight, level lines.

After installation is complete, wipe away any sawdust or adhesive residue. The Red Brown external corner trim will then provide a durable, colour-matched finish that enhances both the appearance and longevity of your Series 1 cladding system.
