Frameless insulated sliding windows and doors

Sky-Frame consists of insulated glazed sections with a glazing strength of 30mm to which a profile of fiberglass-reinforced epoxy resin (GRP) has been glued. The sections are placed in aluminum frames recessed into the floor, wall and ceiling. The sliding sections rest on ball bearing rollers and glide effortlessly.
With the complete separation of inner and outer shells, the excellent insulation values are achieved (rated U-Value = 0.37 BTU/hr-ft²-⁰F). Fixed and sliding sections can be combined as desired, either alternating or with adjoining sliding elements opening in opposite directions.
