System 17-65 SP

65mm Silicone Pointed Curtain Walling

The silicone pointed curtain walling system has been developed as an extension to our standard System 17-65 High Rise Curtain Walling to offer flush vertical and horizontal joints.

Performance Overview

Weather Performance

This system has been designed as a front-sealed system. The system has been impact tested to BS EN 14019 and tested for weather tightness in accordance with the CWCT dynamic test for curtain walling and achieved the following results:

Air Permeability600PaPass
Watertightness600PaPass
Wind Resistance2400PaPass
Dynamic Water Penetration (Aero Engine)600PaPass
Wind Load (Safety)3600PaPass

These levels of performance should be sufficient for any location within the UK and Ireland. For further information on testing and performance contact Metal Technology’s Technical Department.

Where overall screen height exceeds 20 storeys or screen requirements differ from those stated in this literature refer to Metal Technology’s Technical Department.

Acoustic

The system has been successfully acoustically tested to BS EN ISO 10140-2.


Materials

Aluminium profiles are extruded from aluminium alloy 6060 T6 complying with the recommendations of BS EN 12020-2 / BS EN 755-Parts 1 to 9.


Construction

Mullions are square cut and jointed using specially designed jointing spigots. Transoms have notched ends to ensure an easily weather-proofed joint can be provided between mullion and transom. The system is mullion drained and provision is made to drain water out of the mullion at regular intervals.

The system offers the facility to produce screens facetted on plan. Gaskets provide the facility of facetting up to 10°.


Finishes

The range of sections can be provided in either of the following ranges of finishes:

  1. Anodised to BS 3987 or BS EN ISO 7599.
  2. Powder organic coated to BS EN 12206-1.

Where required, a different colour / finish can be provided internally and externally.


Glazing

Glazed units up to 54mm can be achieved. High performance gaskets will ensure the long term weather-tightness of the system. Optional pre-formed vulcanised corner mouldings may be used internally.
