The Douglas decking board 400cm (28x145mm) is a heavy-duty softwood decking solution designed for strong and durable outdoor applications. This board is pressure impregnated with a colorless treatment to enhance resistance against moisture, fungi and weather exposure while preserving the natural look of the wood.

With its robust 28mm thickness and 145mm width, this decking board is ideal for projects that require extra strength and stability, such as high-traffic terraces and larger garden decking structures.

Why Choose Impregnated Douglas Wood?

Douglas fir is a strong and reliable softwood known for its durability and natural appearance. The impregnation process significantly improves outdoor performance without altering the wood’s natural character.

• Heavy-duty 28mm thick decking board
• Pressure impregnated for improved durability
• Colorless treatment preserves natural wood look
• High structural stability and strength
• Suitable for demanding outdoor decking projects
• Cost-effective alternative to hardwood decking

Applications

This Douglas decking board is suitable for a wide range of outdoor uses, including:

• Large garden decking and terraces
• Patio and outdoor seating areas
• Commercial and high-traffic decking
• Balcony and rooftop decking systems
• Walkways and landscaping structures

Natural Appearance

The colorless impregnation maintains the natural warm tone of Douglas wood while improving resistance to outdoor conditions. Over time, untreated wood will naturally weather to a silver-grey patina.

Applying protective oil can help preserve the original colour and extend surface durability.

Installation

For best results, install Douglas decking boards on a stable and well-ventilated substructure. Proper spacing is required to allow for drainage and natural wood movement.

Due to the thickness and density of the board, stainless steel decking screws and pre-drilling are strongly recommended.
