Kristal
120mm
System Characteristics
Thermally broken aluminium system for the construction of minimalist sliding openings.
Aluminium Profiles
• The aluminium profiles are extruded in 6060 aluminium alloy for architectural applications, in accordance with NP EN 12020-02.
• Thermally broken profiles achieved through the insertion of 6.6 polyamide insulating bars, reinforced with 25% glass fibre, measuring 14.6 mm in the fixed frames and 18 mm in the sliding frames.
• Average aluminium profile thickness: 2.0 mm.
Fixed Frames
• 120 mm perimeter fixed-frame section with twin rail for mitre-joint assembly;
• Possibility of applying interior or exterior finishing profiles;
• Lower aluminium sliding guide profile with high-performance double bearings in 316 stainless steel.
Sliding Frames
• Sliding-frame sections with a very narrow sightline, straight-cut and assembled by clip fitting;
• Insulating double glazing with secondary silicone sealing, with a total thickness of 32.4 mm to 32.8 mm, comprising tempered or heat-strengthened external glass and laminated heat-strengthened or tempered internal glass;
• Polymer rail bonded around the entire perimeter of the insulating glazing unit using black structural silicone;
• Recommended structural silicones: Dow Corning 791 black or Sikasil SG20 black;
• Reinforced sliding frames with a contemporary design for large dimensions.
Sizing and Operability
• Minimum – maximum sash dimensions: 300 mm – 3000 mm (W); 500 mm – 3000 mm (H);
• Maximum weight of 300 kg per sash;
• Configurations with 2, 3 or 4 sliding and/or fixed sashes;
• Possibility of corner opening;
• Minimalist sliding system with the sashes sliding over the aluminium profile using high-performance stainless-steel bearings, ensuring easy operation even with extreme weight or dimensional configurations;
• Opening configurations with more than 95% light transmission;
• Air permeability and watertightness ensured by a latest-generation brush seal and marine-grade EPDM gasket;
• Multipoint locking hardware with several locking points, easy to install and adjust;
• Multipoint locking hardware with micro-ventilation included at all locking points;
• Specific handle designed to facilitate opening and closing operations;
• Optional key-operated handle allowing the opening to be operated from the outside.
Performance
• System certified by a notified laboratory for Initial Type Testing (ITT), in accordance with product standard EN 14351-1, for CE marking purposes.
