Fixing and buying guide

What this product is and who it is for

This is a twin and combination flashing designed to weatherproof roof penetrations. It is suitable for builders, roofers and serious DIY customers installing skylights, ventilation units or other roof penetrations on flat roofs. The product is typically used as part of a wider VELUX roofing system to create a complete and durable weatherproofing solution.

Sizing and compatibility

The flashing measures 134cm in length and 140cm in width. You must confirm these dimensions against your project specification and roof penetration size before ordering, as incorrect sizing will compromise the watertight seal. This product is compatible with VELUX roofing systems and should be used in conjunction with other VELUX components for best results.

Installation and fixing

The twin flashing design allows for easy installation and adjustment during fitting. Use suitable fixings appropriate for your roof type and material. Ensure the flashing is positioned to allow water to run off safely and create a complete seal around the roof penetration. For best results, follow VELUX installation guidance and ensure all components are properly secured before weatherproofing the installation.

Pre-installation checks

Before ordering and installing, measure your roof penetration carefully and confirm the 134cm x 140cm dimensions are suitable for your application. Check that you have all other required VELUX components for your complete roofing system. Inspect the flashing on delivery for any damage to the plastic construction that might compromise the watertight seal.
