Visofold Folding Doors
Designed for use as doors for single / double open in or out, sliding and folding screens open in or out, and also windows for fixed light, tilt and turn, single and double sash side hung open in, tilt in, internally beaded, for domestic and light / medium / heavy applications.
Thermal breaks are formed with polyamide strips PA 6.6 25 reinforced with glass fibre, fitted between aluminium extrusions.
All profiles are extruded from aluminium alloy 6060/6063 T5/T6 and comply with the recommendations of BS EN 12020-2; 2001/BS 755-9: 2001. Profiles can be Electrostatic powder coat finished in a range of RAL colours to APA Qualicoat guidelines with the option of BI-colour, different internal and external colours. Other finishes include anodised in satin or bronze colours with EWAA/EURAS-Qualanod quality label. Powder-coated woodstructure finishes are available on request.
The system is built up using a framework hinged to mullions and supported top and bottom on a roller mechanism.
The system allows for a variety of sash and opening combinations and is supplied with security locking on the main stiles. Options include outward or inward opening profiles, internal beading and a choice of 4mm to 38mm glazing.
Windows are manufactured according to customer requirements from a range of standard profiles and are designed to incorporate a range of vent openings and various options, therefore it is advisable to contact Smart Systems technical design department early in the design process.
Product tested to BS 6375: Part 1. Weather Tightness classification:
Air Permeability – Class ‘C’.
Water Tightness – 300pa.
Wind resistance – 1800pa
