Abstract
A fenestration assembly comprising a sliding glass assembly that slides between a fully closed position and a fully open position in which the sliding glass assembly is received into a pocket of the fenestration assembly. The pocket is covered on at least one side with insulation. The fenestration assembly may have two sliding glass assemblies. The fenestration assembly may be used in an energy efficient building system.
Claims26
An energy efficient fenestration assembly for enclosing an opening in a building wall and configured to overlay a conventional window the fenestration assembly comprising:
- a frame having at least four edges surrounding first and second sides to be partially covered by building material, the frame defining:
- an opening from the first side to the second side;
- and
- a first pocket section next to the opening and sized at least equally to the opening,
- the frame comprising:
- an insulating mullion pocket between the opening and the first pocket section;
- and
- three respective insulating edge pockets within three of the at least four edges of the frame, the three of the at least four edges surrounding the opening;
- an insulating section between the first pocket section and one of the first or second sides of the frame;
- and
- a first sliding insulating glazing unit supported on a bottom edge by roller carts moveable within a raceway of the frame, the first sliding insulating glazing unit capable of sealing the opening and moveable between:
- a fully-closed position in which the first sliding insulating glazing unit is located substantially within the opening and seals the opening;
- and
- a fully-open position in which the first sliding insulating glazing unit is located substantially within the first pocket section of the frame,
- wherein the first sliding insulating glazing unit comprises two or more glass sheets that are spaced apart and sealed at perimeter edges of the two glass sheets and features one or more low emissivity coatings facing at least one glazing cavity between the glass sheets and where the center-of-glass provides more thermal resistance than the perimeter edges, and
- wherein in the fully-closed position, the perimeter edges of the first sliding insulating glazing unit are located within the three insulating edge pockets and the insulating mullion pocket of the frame.

An energy efficient fenestration assembly installation over an opening in a building wall, the fenestration assembly installation comprising:
- a conventional window installed within the opening in the building wall;
- an energy efficient fenestration assembly arranged to overlap the conventional window, the energy efficient fenestration assembly comprising:
- a frame having at least four edges surrounding first and second sides to be partially covered by building material, the frame defining:
- an opening from the first side to the second side, the opening overlapping the conventional window installed within the opening in the building wall;
- and
- a first pocket section next to the opening and sized at least equally to the opening, the first pocket section overlapping the building wall,
- the frame comprising:
- an insulating mullion pocket between the opening and the first pocket section;
- and
- three respective insulating edge pockets within three of the at least four edges of the frame the three of the at least four edges surrounding the opening;
- an insulating section between the first pocket section and one of the first or second sides of the frame;
- and
- a first sliding insulating glazing unit supported on a bottom edge by roller carts moveable within a raceway of the frame, the first sliding insulating glazing unit capable of sealing the opening and moveable between:
- a fully-closed position in which the first sliding insulating glazing unit is located substantially within the opening and seals the opening;
- and
- a fully-open position in which the first sliding insulating glazing unit is located substantially within the first pocket section of the frame,
- wherein the first sliding insulating glazing unit comprises two or more glass sheets that are spaced apart and sealed at perimeter edges of glass sheets and features one or more low emissivity coatings facing at least one glazing cavity between the glass sheets and where the center-of-glass provides more thermal resistance than the perimeter edges, and
- wherein in the fully-closed position, the perimeter edges of the first sliding insulating glazing unit are located within the three insulating edge pockets and the insulating mullion pocket of the frame.
