C ORRER with thermal break

Kristal System
Minimalist concept sliding system with RPT

System features

Aluminum system with thermal break to execute sliding spans with a minimalist concept.

Aluminum profiles

The aluminum profiles are extruded in the 6060 aluminum alloy for architecture according to standard NP EN 12020-02.
Profiles with thermal break obtained by insertion of 6.6 mm polyamide insulating rods reinforced with 25% fiberglass.
14.6 mm on fixed rims and 18 mm on mobile rims.
Average thickness of 2.0 mm aluminum profiles.

Fixed rims

Section of 120 mm fixed perimeter frame with bi-rail for miter assembly;
Possibility of applying interior or exterior trim;
Aluminum bottom sliding guide profile with high performance double bearings in 316 stainless steel.

Movable hoops

Section of the movable rings of very reduced view of straight cut by assembly by clipping;
Double insulating glass with secondary silicone sealing from 32.4 mm to 32.8 mm in total thickness, composed of types of glass
tempered or thermosetting exterior and thermoset or tempered laminated interior glass;
Polymer trough glued around the perimeter of the insulating glass with black structural silicone;
Recommended structural silicones: Dow Corning 791 black or Sikasil SG20 black;
Reinforced mobile rims of contemporary line for high dimensioning.

Dimensioning and maneuverability

Minimum dimensions - maximum sheets: 300 mm - 3000 mm (W); 500 mm - 3000 mm (H);
Maximum weight of 300 kg per sheet;
Typologies of 2, 3 or 4 movable and / or fixed sheets;
Possibility of opening in corner;
Sliding system of minimalist concept with sliding of the sheets on the aluminum profile made with steel bearings
high performance stainless steel for easy opening of the span even with extreme weight or dimension configurations;
Typologies of spans with more than 95% brightness;
Air permeability and water tightness ensured through the latest generation plush and joins in quality EPDM
Multipoint hardware with several closing points and easy to apply and adjust;
Multipoint hardware with micro-ventilation included in all closing points;
Specific handle to facilitate the opening and closing maneuver of the span;
There is the option of a keyed handle to allow the opening of the opening from the outside.


System certified by notified laboratory for Initial Type Tests (ITT) according to the product standard EN 14351-1 for the purposes
CE marking.

Categories achieved in the evaluation of the Kristal typology window system:
1. Air permeability: Class 4 (test standard EN 1026)
2. Water tightness: Class 7A (test standard EN 1027)
3. Wind resistance: Class C5 (test standard EN 12211)

Categories reached in the evaluation of the Kristal door typology system:

2. Water tightness: Class 6A (test standard EN 1027)
3. Wind resistance: Class C2 (test standard EN 12211)
4. Micro-ventilation air permeability: Class 1 (test standard EN 1026)

Categories reached in the evaluation of the KRISTAL system for determining the maneuvering forces (EN 12046):
1. Release of closing hardware: Class 2
2. Sheet opening: Class 1
3. Leaf closure: Class 1
4. Locking hardware coupling: Class 2

Category achieved in determining resistance to repeated opening and closing (5000 cycles): Class 1 (EN 1191)

Coefficient of thermal transmission of span of 2 sheets with 5.0 mx 3.0 m with glass Ug = 1.0 W / m2K, with interim "Warm Edge" effect:
• Uw = 1.29 W / m2K

Acoustic attenuation coefficient of 2-sheet span with acoustic glass 8/16 / 44.1:
• Rw (C; Ctr) = 41 dB (-1; -5)

Application areas according to RCCTE (depending on the Ug value): I1, I2, I3, V1, V2, V3.
