VELUX Twin and Combination Flashings 134x98cm EBP UK04 0021B
Typical applications and installation
These flashings are used to seal the gap between VELUX rooflights and the roof structure on pitched roofs. They accommodate variable roof angles and pitches, making them versatile for different roof designs. The 134x98cm size matches most standard VELUX rooflight dimensions. Installation involves positioning the flashing around the rooflight opening, ensuring the timber sits flush against both the rooflight frame and the roof surface. The flashing must be secured and sealed to create a complete watertight barrier that directs water away from the rooflight frame and into the roof drainage system.
- Suitable for pitched roofs with varying angles and pitches
- Works with standard VELUX rooflight sizes at 134x98cm
- Creates watertight seal to prevent weather ingress around rooflight perimeter
- Accommodates both twin and combination rooflight configurations
Material properties and durability
The Grade A timber construction provides structural integrity and stability during and after installation. The EBP (Exterior Brushed Paint) finish is specifically formulated to resist weathering, UV exposure, and moisture damage. This finish helps protect the timber from the elements and extends the service life of the flashing. The combination of quality timber and protective finish ensures reliable performance in exposed roof conditions over many years.
- Grade A timber ensures structural integrity
- EBP finish provides weathering resistance and durability
- Designed to withstand exposure to rain, wind, and UV
- Maintains performance across variable roof pitches
Installation considerations and limitations
These flashings are designed specifically for VELUX rooflights and pitched roof applications. Correct installation is essential for watertight performance. The flashing must be properly positioned to ensure water runs away from the rooflight frame and does not pool or penetrate gaps. Installation should follow VELUX guidance to ensure compatibility with your specific rooflight model and roof construction. These flashings are not suitable for flat roofs or non-VELUX rooflight systems. Ensure the roof structure is sound and properly prepared before installation.
- Designed for VELUX rooflights only
- Suitable for pitched roofs with variable angles
- Not suitable for flat roof applications
- Requires proper preparation of roof opening and structure
Maintenance and on-site handling
Inspect flashings regularly to ensure the seal remains intact and there are no signs of water ingress around the rooflight. Check that the EBP finish has not been damaged and that the timber is not showing signs of rot or deterioration. Store flashings in dry conditions before installation to prevent moisture absorption. Handle carefully on site to avoid damage to the timber edges or finish. Once installed, the flashing should require minimal maintenance beyond periodic inspection to confirm the watertight seal is performing correctly.
