Abstract: A combination of profiles for forming slider and double hung sash windows or patio doors includes a common outer profile and two different inner profiles so that one inner profile can be used to form the double hung and the other to form the slider. This allows the slider top inner to be cut away to form a floating section resting on the top of the sash. This allows the drain holes to be formed separately in the inner and the outer to be longitudinally offset to prevent direct air penetration. The sash frame is formed with a removable glass stop on one side which snaps into engagement at right angles to the glass surface of the sealed unit to allow formation of a tri-pane with 0.5 inch spacing and to allow the use of two strips of adhesive one on each side of the sealed unit with no need for drainage.
