The Individual fields are formed by screwing short vertical uprights between horizontal profiles, placed across the width of the door. All the infill fields of a door leaf are identical in size and the top and bottom panels are of solid construction. The glazing consists of two transparent acrylic panes with an airtight seal to form double glazed construction. Cross section of glazing - 2.5mm - 14 mm - 2.5mm.

The door is perfectly balanced by means of polyester powder coated helical springs at high level, mounted on galvanised steel plates and quality bearings to give smooth and quiet operation. CABLE BREAKAGE devices are fitted as standard to prevent the uncontrolled dropping of the door. Rubber seals are fitted to the top and both sides of the door with a triple blade seal to the bottom for good protection against weather.
