The VELUX twin combination flashing allows for two VELUX windows to be installed side by side with an 18mm gap between the windows, bringing in a larger area of light to brighten up a room. This VELUX twin combination flashing is for slate up to 8mm thick.
VELUX recommend using a support trimmer when installing the twin combination for the 18mm frame gap as it's needed to ensure strength and stability between the windows.
