Siberian larch decking boards 28×90mm offer a durable and versatile solution for external timber decking. Naturally resistant to moisture and decay, Siberian larch is widely used for garden decking, terraces, and landscaping projects across the UK.

The narrower 90mm board width provides a more detailed and refined decking appearance, making it suitable for contemporary designs and smaller-scale layouts. This product forms part of our decking boards range and offers a practical alternative to both treated softwood decking and tropical hardwood decking.
