Refresh your exterior spaces with the Portland Walnut outdoor wall cladding. Designed to bring an inviting look to your home’s exterior, these panels offer an attractive wood effect appearance that closely resembles timber without the upkeep. Whether you are updating a patio seating area or refreshing the outside of your property, this exterior cladding provides a stylish and practical solution for modern living.
Manufactured from modern materials, this composite cladding features a highly realistic wood grain design in a rich Walnut finish. The panels are UV resistant, ensuring they maintain their vibrant colour despite prolonged exposure to sunlight and changing weather conditions without cracking or fading. Because it resists moisture, mould, and insects, this composite slat cladding requires significantly less maintenance than traditional materials. Each panel is finished with smooth edges for added safety in residential settings.
These versatile garden wall panels are suitable for both indoor and outdoor use, making them an excellent choice for extending your interior design into the garden or acting as stylish fence cladding. Sold in packs of four, you can choose between 290cm lengths (providing 2.32m² of coverage per pack) or 180cm lengths (providing 1.44m² per pack). Each panel measures 21.9cm wide with a 20cm usable width after the overlapping installation, and has a thickness of 2.6cm. To complete your project, matching corner trims are available. If Walnut does not suit your scheme, the Portland range is also available in Light Oak, Smoked Oak, Grey Oak, and Black Oak.
