Fixing and buying guide

Who this product is for

This flashing system is for builders, roofers, and experienced DIY installers working with VELUX roof windows on pitched roofs. It suits projects using standard tile or slate roof profiles where the window opening aligns with the 94x160cm flashing dimensions. Use these flashings for new roof window installations or when replacing existing VELUX windows in pitched roof applications.

Compatibility and sizing

The EKL PK10 S0312 flashings are specifically sized for VELUX windows with 94x160cm dimensions. They are compatible with pitched roofs finished in standard tile or slate profiles. Before ordering, confirm your window opening dimensions match this specification and verify your roof profile type. These flashings integrate directly with the VELUX window frame, so compatibility with your exact window model is essential.

• Flashing dimensions: 94x160cm
• Roof types: Pitched tile and slate installations
• Material: Aluminium with integrated sealing components
• Installation method: Integrated with VELUX window frame

What is included and pre-installation checks

Each EKL PK10 S0312 unit provides a complete twin and combination flashing system ready for installation. Before fitting, inspect the flashing for any damage and ensure your VELUX window frame is clean and dry. Verify that the roof opening dimensions are accurate and that the surrounding roof structure is sound and level. Check that all roof tiles or slates around the opening are secure and undamaged, as poor roof condition will compromise the weathertight seal.

• Inspect flashing for transport damage before installation
• Confirm window opening dimensions match 94x160cm specification
• Ensure roof surface is clean, dry, and structurally sound
• Verify roof tiles or slates are secure around the opening

Installation and sealing

The twin and combination design allows flexible installation across different roof profiles, reducing the need for multiple flashing types. The integrated sealing components work with the VELUX frame to create a weathertight barrier. Follow VELUX installation guidance carefully, ensuring the flashing sits correctly on the roof surface and integrates properly with the window frame. Correct installation is critical to prevent water ingress and maintain thermal performance around the window perimeter.

• Follow VELUX installation instructions for your specific window model
• Ensure flashing sits flush on the roof surface
• Verify integrated sealing components are properly engaged
• Check weathertight seal around entire window perimeter after installation
