APPLICATION
Curtain wall system with fixed frames and Italian projecting windows of equal visible surface.
Double design:
- VEC, structural glazing with edge frame (technically approved by French testing and research center CSTB);
- VEP, structural glazing with slim glazing beads
(not subject to technical approval).

STRUCTURE
Extruded aluminium profiles (6060 BAT T5 or 6063T6 alloy). Structure composed of mullions and transoms. Anchoring rails and adjustable brackets for fixing to building structure. Various profiles to meet exposure and inertia requirements..

GLAZING FRAMES
Extruded aluminium profiles (6060 BAT T5 or 6063T6 alloy ). Frame assembling by crimping corner cleats. 6- or 8-mm single glazing, 66.2 laminated glazing (12.8 mm) or 24-mm double glazing (VEC). 6- to 24-mm glazing (VEP). Drop-and-lock, screw avoiding fixing of frame into structure. Concealed Italian projecting window. Clearance between panels: 10 mm (VEP), 14 mm (VEC). .

WEATHERPROOFING
Triple EPDM gaskets, applied sealant for joints with shell.

FINISH
Anodizing: 20-class satin for silver, 15-class for other colours (20-class on order). In accordance with international QUALANOD and EWAA-EURAS standards and French NFA 91450 standard.
80-micron powder coating with QUALICOAT seal.

DISTINCTIVE FEATURE
Same structure as VEC BL curtain wall

MANUFACTURING
• Screws: stainless steel

• Weatherproofing for aluminium profile joints: 1st quality putty.

• Gluing rod no. 8802 must compulsorily be fixed to the profile it is used with, before cutting.

• Opening frames are hung on structure mullions. Stainless steel projecting arms for Italian windows, preventing washing from inside (maximum leaf weight 100 kg, maximum height 1750 mm, maximum width 1600 mm).

• All other frames and panels are fixed by means of kits no. 8917 and 8918, and are individually removable. Unwanted removal is prevented by a safety device (CHCM5X12 screw + 2 RONDEL5 washers).

• Gluing rod 8802 is used with three types of glazing:
. 24-mm insulating glass certified for structural glazing, with frame profile 8803;
laminated glass, maximum 13 mm, with frame profile 8804;
. 6- or 8-mm tempered sheet glass of various types (enamelled, pot-opal, clear, tinted,...): with frame profile 8807 as slightly ventilated cladding in front of concrete or masonry wall, with frame profile 8826 as slightly ventilated external lining in front of infill panel.

• Drainage as shown under headline "GLAZING".

• Each fixed or opening frame is fitted out in the workshop with an EPDM cover gasket, glued in corners and designed to overlap the adjacent frames’ ones.

JUSTIFICATIONS
For each site, justifications of suitability for the project must be given by the glue manufacturer and by the glass manufacturer, complying with the locally applicable standards.

SAFETY DEVICE
All glazed frames, both fixed or opening, must be fitted out with a safety device preventing glass fall in case of defective bonding (corner piece 8934 or small piece of profile 8830 pop-riveted at each corner, drilling before gluing).

FIXING
Once the shell is completed, the fixing brackets are put in place. These brackets are fixed into continuous or discontinuous rails, which have been incorporated into concrete while casting. The use of expanding bolts is also possible .

The main operations are:
• Joining of structure or raising of ladders, and bolting to brackets.
• Joining of transoms between ladders.
• Fixing of insulating material on concrete.
• Fixing of panels or opaque glazed fixed frames (fixing of safety device preventing unwanted removal) .
• Fixing of opening frames. This is currently done in the workshop for opening frames incorporated into ladders.
• Finishings.
