We are pleased to announce our new aluminium sliding/folding door into the Crown range. This stunning new addition to the Crown aluminium door family will be exceptionally popular with its unique Shootbolt & 'D' Handle and continuous hinges. The innovative hinge means that there are no bulky or unsightly hinges to disrupt the contemporary sightlines.
The door features hardware designed specifically for doors - as opposed to 'window' hardware utilised on some doors of this type. This allows the Crown Sliding/Folding Door to not only be securely locked but also used as a main entry or exit operable from both inside and outside, using our robust & secure Multi-Point Lock.

Performance (Weather)
When tested in accordance with BS6375:Part 1:2009 all products fitted with standard
thresholds, when manufactured installed and glazed strictly to the enclosed details,
will achieve the following weather performance -
Open Out
Water Tightness Class 9A (600 Pa)
Air Permeability Class 3 (600 Pa)
Wind Resistance Class 4 (1600 Pa)
Exposure Category** 1600
Open In
Water Tightness Class 3A (150 Pa)
Air Permeability Class 3 (600 Pa)
Wind Resistance Class 4 (1600 Pa)
Exposure Category** 1200
Rebated Low Threshold (CF926) - Open Out
Water Tightness Class 3A (150 Pa)
Air Permeability Class 3 (600 Pa)
Wind Resistance Class 4 (1600 Pa)
Exposure Category** 1200
Low Threshold (DF297) (Open Out and Open In)
Low threshold doors should not be used in exposed conditions, and as with any low
threshold door, additional measures to prevent water coming into contact with
internal floors may be required.
Performance (Mechanical)
The door assembly has been cycle tested under maximum panel load conditions to
10,000 cycles (equivalent to opening once a day, for 27 years).
Performance (Corrosion Resistance)
The rollers and top guides have been salt spray tested in accordance with
BS EN 1670 and achieved Grade 5 (480hrs), defined as "Exceptionally high
corrosion resistance" and suitable for “Service outdoors in exceptionally severe
conditions where long-term protection of the product is required”.
Performance (Thermal)
When calculated in accordance with BS EN 10077-2, the Crown Sliding Folding door,
fitted with standard threshold, will achieve the thermal transmittance shown in the
tables below for various sizes, no. of panes and centre pane U value. For
intermediate sizes, use nearest size below actual. Where warm edge spacers are
used, reduce U values shown by 0.1 W/m2K. For Low Threshold doors, add 0.1
W/m2K to the resulting U value.
