System 17-65 High Rise Capped Curtain Walling

A highly efficient, thermally enhanced aluminium framed 17-65 mm curtain walling system.

Glazing and curtain wall systems need to be designed to work in harmony with the building construction. The consequence of this can be greater structural spans resulting in increased building movement.

Metal Technology’s System 17-65 has been designed to help address one of the main complexities associated with this type of construction, that of accommodating greater floor slab deflection.

Weather Performance:

The curtain walling system has been successfully tested to BS EN 13050 for weather testing, and CWCT hosepipe tested. The system met the requirements of the CWCT dynamic test for curtain walling and achieved the following results:

• Air Permeability: 600 Pa - Pass.
• Watertightness: 600 Pa - Pass.
• Wind Resistance: 2400 Pa - Pass.
• Dynamic Water Penetration (Aero Engine): 600 Pa - Pass.
• Dynamic Water Penetration European Standard (Fan) BS EN 13050: 900 Pa - Pass.
• Hose pipe test (22l/min @ 220Pa): Pass.

The system has been successfully impact tested in accordance with CWCT Section 15, BS EN 13049, and BS EN 14019.

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.

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 faceting up to 10°.
