Fakro EFW Flat Roof Kerb Upstand and Flashing

Fakro EFW Flat Roof Kerb Upstand and Flashing

The Fakro EFW Flat Roof Kerb Upstand and Flashing provides a practical way to install standard Fakro pitched roof windows on flat roofs. Designed to create the required slope while helping manage rainwater, the system supports a secure and weather-resistant installation with a neat, finished appearance. By creating a 15° pitch, the EFW kerb allows a pitched roof window to be installed on a flat roof while encouraging effective water runoff. It is suitable for roofs with a maximum existing pitch of 15°, making it a versatile option for a range of low-pitched and flat roof projects.

Designed to Create a 15° Pitch

The EFW kerb is specifically designed to provide a 15° slope for the installation of standard Fakro pitched roof windows. This angled installation helps water run away from the window more effectively, supporting improved weather protection and drainage. It offers a straightforward solution when the benefits and appearance of a pitched roof window are required on a flat or low-pitched roof.

Strong and Durable Construction

The kerb upstand is manufactured from 18mm external plywood, providing a strong and durable base for the roof window. The construction is designed to withstand typical external roof conditions and provide long-term reliability when correctly installed.

Weather Protection and Drainage

The Fakro EFW combines the kerb upstand with flashing to help create a secure installation around the roof window. The angled design supports effective water drainage, while the flashing helps provide protection against weather exposure. Together, these components help create a more secure and weather-resistant connection between the roof, kerb and pitched roof window.

Contemporary RAL7022 Finish

The EFW kerb and flashing feature a RAL7022 finish, providing a neutral, contemporary appearance that can complement a wide range of roofing materials and exterior styles.

Suitable for Flat and Low-Pitched Roofs

The Fakro EFW is suitable for roof applications with a maximum pitch of 15°. Its design makes it particularly useful when a standard pitched roof window needs to be incorporated into a flat or low-pitched roof while maintaining an appropriate angle for drainage.

Roof Tiles & Fittings:
