Composite Internal Corner Red Brown - Series 1

The Composite Internal Corner Red Brown – Series 1 trim is specifically designed to provide a neat, professional finish wherever two cladded walls meet on an internal corner. It conceals cut edges of Series 1 slatted cladding panels and helps maintain a consistent, high-quality appearance across the entire installation.

Manufactured from robust, low-maintenance composite material, this trim offers excellent resistance to weathering, impact and UV exposure. The Red Brown colourway works seamlessly alongside matching Series 1 slatted cladding panels, providing a warm, timber-inspired look that complements a wide range of exterior and interior schemes. The smooth finish delivers a clean, modern appearance that frames your cladding beautifully.

Measuring approximately 3.6m in length with a profile of around 45.75mm x 38.75mm, the internal corner trim is suitable for full-height walls and taller façades. It is lightweight yet sturdy, making it straightforward to handle and install over timber or composite battens. As with the wider cladding system, it requires very little upkeep beyond occasional cleaning.

For anyone seeking a durable, visually consistent solution for finishing internal corners on composite cladding, this Red Brown Series 1 internal trim is an essential component that ensures a smart, long-lasting result.

Before fitting the internal corner trim, ensure that your Series 1 cladding battens are installed correctly and that any adjacent panels are cut and positioned according to your layout. The substrate should be clean, dry and structurally sound.

Measure the full height of the internal corner and cut the trim to length using an appropriate saw for composite materials. Offer the trim up to the corner to check the fit, making sure it sits snugly and straight along the entire height.

The trim can be fixed by pre-drilling through the faces into the underlying battens and securing it with suitable exterior-grade screws, or by using a compatible outdoor adhesive where appropriate. If using screws, space fixings evenly along the length, taking care to avoid overtightening and distorting the profile.

Once the trim is securely in place, install the Series 1 slatted cladding panels so that their cut edges sit neatly within the internal corner profile. Check alignment regularly as you work up the wall to maintain straight lines. Finally, clean away any dust or adhesive residue. The internal corner will then provide a crisp, colour-matched junction that enhances the overall finish of your cladding.
