Extended aluminium sub cills (may also be referred to as 'RAS' cills) are available for fitting underneath the window to shed rain away form the building. They are available in a range of profiles to suit a variety of cill details, wall thickness and how far the window is set back within the window opening. Aluminium extension cills are also available powder coated in a wide range of colours from the standard RAL colour range. For further information, please contact your nearest NorDan office. |
