What is included and pre-installation checks

This product is the flashing component only. Ensure you have ordered the correct VELUX roof window or Sun Tunnel system to work with this flashing, as they must be purchased and installed together as a complete system. Before installation, inspect the flashing for any damage in transit and verify that your roof structure, tile type, and pitch are suitable for a recessed flashing installation. Check that the opening in your roof is correctly sized and prepared to accept the 1340×1400mm flashing dimensions.

• Flashing component only; roof window or Sun Tunnel system ordered separately
• Inspect for transit damage before fixing
• Confirm roof pitch and tile type are compatible
• Verify roof opening dimensions match 1340×1400mm specification
