Shadow gap cladding is loved for its unique profile that creates clean, defined lines and subtle depth. Its design enhances contemporary aesthetics while providing effective water runoff, making it suitable for outdoor use. Durable, easy to install, and versatile, shadow gap cladding is perfect for a wide range of architectural styles.

Tools and Materials You’ll Need

Gather the following essentials before starting your project:

• Shadow gap cladding boards
• Treated timber battens
• Fixings
• Breathable membrane
• Drill or nail gun
• Saw (hand or power)
• Spirit level and tape measure
• Weatherproof finish
• Safety gear

Step 1: Surface Preparation

Prepare the wall for cladding installation:

• Inspect the surface: Make sure it’s clean, dry, and structurally sound.
• Attach a breathable membrane: Temporarily secure it with tape, then fix it properly with galvanised staples, nails, or screws with washers. This creates a moisture barrier while allowing ventilation.

Step 2: Install the Battens

Treated timber battens are essential for creating the framework for your shadow gap cladding.

• Measure and mark: For horizontal shadow gap cladding, position vertical battens.
• Spacing: Space battens 400–600mm apart, with additional battens around windows, doors, and corners for added support.
• Secure battens: Use screws or fixings suitable for your wall type to attach them securely.

Step 3: Prepare the Shadow Gap Boards

• Inspect the boards: Check for any defects and allow the boards to acclimate to site conditions for 5–7 days to minimise movement after installation.
• Cut to size: Trim the boards to the required length, leaving a 2mm gap at edges to allow for natural expansion.

Step 4: Start Cladding

Time to start attaching your boards!

• Begin at the bottom: For horizontal cladding, start at the base of the wall; for vertical cladding, begin at one side.
• Position correctly: Ensure the shadow gap profile is properly aligned to achieve the desired defined lines.
• Check alignment: Use a spirit level to ensure the first board is perfectly straight.

Step 5: Fix the Boards

• Secure the first board: Fix the board to the battens using stainless steel screws or nails. Ensure the fixings are discreetly placed where they won’t interfere with the shadow gap profile.
• Repeat and overlap: Install each subsequent board with the specified gap to create the shadow effect. Continue until the wall is covered.

Step 6: Finishing Touches

• Trim to fit: Cut boards to fit neatly around windows, doors, and other openings.
• Add edge trims and mouldings: Use corner trims and mouldings to create a professional, polished finish.

Step 7: Protect Your Timber

To enhance durability and maintain the stylish appearance of your shadow gap cladding:

• Apply a protective finish: Use an oil, stain, or paint to preserve the timber’s color and guard against weathering.

Reapply as necessary: Regular maintenance will keep your cladding looking sharp for years to come.
