With easy and discrete installation, this VELUX flashing delivers a watertight seal around the window and a lacquered grey aluminium finish. Materials are corrosion-free.
This flashing is compatible with a roof pitch of 15° to 55°. For standard height installations, you will find red lines along the window frame that signal where brackets should be fitted at the top and bottom.
