Fixing and buying guide

Who this product is for

This flashing system is intended for builders, roofers, and experienced DIY installers undertaking pitched roof projects with multiple roof windows. It suits projects where two VELUX roof windows need to be installed in close proximity and where a streamlined, integrated weatherproofing solution is preferred over separate flashing units. The system is particularly valuable for new-build and renovation work on traditionally finished pitched roofs.

Compatibility and sizing

The 94x160cm aperture size is compatible with standard roof window spacing on pitched roofs. The EKP PK10 0021E specification ensures compatibility with pitched roof pitches and both tile and slate roof finishes. Before ordering, confirm that your two roof windows are positioned to suit this combined aperture dimension and that your roof pitch falls within the standard range for this flashing type. Check your roof material type to ensure tile or slate compatibility.

• Aperture size: 94x160cm
• Suitable for pitched roofs with tile or slate finishes
• Specification code: EKP PK10 0021E
• Dual-window configuration for integrated installation

What is included and material composition

This flashing system comprises integrated upper and lower components manufactured from aluminium and synthetic rubber. The dual-component design works together to create a unified water-resistant barrier. The aluminium and synthetic rubber construction provides durability and flexibility to accommodate roof movement and weathering.

• Upper and lower flashing components included
• Aluminium and synthetic rubber construction
• Single integrated system rather than separate units
• Minimises additional sealant and joinery requirements

Pre-installation checks and preparation

Before installation, verify that your roof structure can accommodate the 94x160cm aperture dimension and that the two roof window positions align with this spacing. Inspect the roof pitch to confirm it falls within the standard range for pitched roof installations. Check that your roof finish is either tile or slate, as specified. Ensure the roof structure is sound and properly prepared for window installation. Have all necessary tools and fixings ready, and review VELUX installation documentation specific to this flashing code to understand the integration sequence between the upper and lower components.

• Confirm roof pitch is suitable for pitched roof flashing
• Verify roof material is tile or slate finish
• Check that two window positions align with 94x160cm aperture
• Inspect roof structure for soundness and readiness
• Review VELUX installation guidance for EKP PK10 0021E before work begins
