After installation, you may notice a slight lightening of the product’s colour. This is a natural part of the weathering process, caused by initial exposure to sunlight. This temporary change typically settles within 6 to 12 weeks. Once this period has passed, the product’s colour will remain stable and will not experience further discolouration under normal conditions.
Neowall Slatwall External Trim is designed to give a clean, professional finish to the exposed edges of your outdoor slatwall installations. Crafted from the same high-quality material as the slatwall panels, it ensures a seamless transition at wall ends, open edges, and other exposed areas — preventing them from looking rough or incomplete.
This trim not only enhances visual appeal but also adds durability to high-contact zones. It’s weather-resistant, helping protect against sun exposure, moisture, and everyday wear, while reinforcing the edges to reduce minor chips or damage over time.
