There is provided by this invention an improved fenestration construction with an insulated glass pane construction. The fenestration can have a sash that includes an peripheral frame-like member which defines a central opening, an outer face and glazing engaging surfaces. A glazing engaging stop member constructed to cooperate with the peripheral frame- like member in forming the sash. A membrane which is gas and a moisture vapor flow resistant is applied to the glazing engaging surfaces. A primary and a secondary sealant is also applied to the membrane at the glazing engaging surfaces. The primary sealant is adjacent yet to-be-formed insulated space between the panes. The secondary seal is positioned outwardly thereof. An external pane is positioned in the sash and engages primary sealant and secondary sealant. A second pane is positioned in the sash space but generally parallel to the exterior pane and also engages sealant. The stop is then secured to the frame. The pane, sealants and membrane form an insulated space between the panes.
