System 17 Concealed Vent

A concealed top hung casement opening vent, designed to be fixed within Metal Technology curtain walling systems, to appear frameless externally.

Can be incorporated with Metal Technology's standard capped System 17, System 17 Latitude, and System 17 SP to provide a frameless opening vent.

Finishes:

• Available in both anodized and powder coated finishes.
• This system can accommodate a different colour finish internally to that used externally.
• Metal Technology's powder coating is produced to Qualicoat standards.

Construction:

• Frame members are mitre cut at 45°, corners are reinforced with extruded aluminium crimping cleats and corner braces, and a secure joint is formed by pneumatically crimping into the extruded crimping cleat.
• Mullion and transom bars are square cut shaped and fixed securely to the frame by means of stainless steel screws and fixing cleats.
• Glass is structurally bonded to the vent profile by specialist silicone applicators.
• All frame joints are sealed during construction against entry of water using Metal Technology’s two-part adhesive.

Thermal performance:

Metal Technology’s Concealed Vent, in conjunction with the correct glass specification, is designed to aid compliance with the latest thermal requirements of the current building regulations.

Metal Technology recommend that only A2 or A4 Austenitic (300 series/class 70) stainless steel fixing screws are used in the assembly of their products.
