Installation and sealing
The recessed flashing creates a watertight seal around the opening perimeter. Position the flashing around the window or door frame before final fixing, ensuring it sits flush with the surrounding construction.

Ensure the flashing is fully seated and secured according to the opening dimensions and your project specifications.

Durability and maintenance
The flashing is manufactured from durable plastic with UV stabilisation to withstand external exposure and weather conditions. This treatment protects against degradation from sunlight and environmental exposure over time. Periodic inspection of the seal around the flashing is recommended to ensure continued watertight performance, particularly after severe weather. Clean debris from around the flashing to maintain effective water drainage.
