A spacer channel for a frame which separates window panes to form an insulated window has a plurality of openings through a wall of the channel that faces outward along the periphery of the frame and glass sandwich. The openings are designed to prevent significant passage of sealant from the outside of the channel to the inside of the channel through the openings. This is done by the cross sectional area of each opening being so small that it resists viscous flow of the sealant through the opening, or by a cover over the opening.
