Fixing and buying guide

Who this product is for

Check the pitch and profile type of your tiles to ensure compatibility. The compact size suits typical roof penetrations and wall cladding installations.

• Measure your profiled tile profile dimensions before purchase
• Confirm the flashing size matches your project specification
• Suitable for both roofing and wall cladding applications
• Grey colour coordinates with standard roofing and wall materials

What is included and pre-installation checks

Each unit comprises the profiled tile flashing with integrated BDX 2000 membrane in a 2in1 design. Before installation, inspect the flashing for any damage during transit. Ensure the membrane is intact and free from tears or defects. Check that the surrounding tile profile, roof structure, and wall surface are clean, dry, and free from debris. Confirm that all necessary fixings and sealants specified by the manufacturer are available on site.

• Inspect the flashing and membrane for damage before use
• Ensure the membrane is intact with no tears or defects
• Clean and prepare the installation surface
• Have all required fixings and sealants available on site

Installation and adjustment

The 2in1 design allows for straightforward installation and on-site adjustment. Install in line with current site practice and Velux manufacturer guidance. The integrated membrane eliminates the need for separate membrane installation, streamlining the process. Ensure the flashing is correctly positioned around the tile profile and securely fixed according to the manufacturer's instructions. The grey colour provides a discreet finish that requires no additional treatment or painting.
