Panels fold outwards or inwards, to the left and/or right, and the outer panels can be cleaned from inside by simply pulling out the hinge pins.

1.5  Applications: Balcony glazing, Under glass canopies, Partitions, Patios.

2  DIMENSIONS AND CONSTRUCTION

2.1  System type: Non-insulated bi-folding door.

2.2  Material: Aluminium.

2.3  Thermal break: None — non-insulated.

2.4  Locking stroke: 24 mm into top and bottom frame profiles.

2.5  Height adjustment: Approx. 6 mm after installation.

2.6  Floor tracks: Rebated running and floor tracks, accessible variants available.

3  GLAZED ELEMENTS

3.1  Double all-round seal: vertical double EPDM seals, horizontal double brush seals with PE baulk.

3.2  Running and floor tracks with rebates for drainage.

3.3  Tongue-and-groove connectors in the panel joint for large glass panels.

4  PERFORMANCE

4.1  Thermal transmission: Non-insulated.

4.2  Water tightness: Up to 4A.

4.3  Wind load resistance: B1.

4.4  Sound reduction: Up to 31 dB.

4.5  Air permeability: Class 2.

4.6  Performance values quoted are the manufacturer's published figures for this system.
