Curtain Walling

Curtain Walling


Windell's commercial curtain walling offers the designer a wide and diverse range of profiles that will provide structural integrity, weather performance and thermal enhancement. Considered a highly cost-effective, quality engineered glazing solution, their system complies with current British Standards and is considered as an appropriate option for expansive high rise glazed applications. The system has been extended to provide the designer with a mono or dual pitch roof light system offering a complementary appearance to that of the vertical façade. All commercial window and door systems are complementary to the system offering the designer complete versatility.

1Product Advantages

This system is designed for use in multi-storey and roof glazing applications and is capable of accommodating a variety of glazing, panel and opening options. As with all curtain walling systems, intermediate tie backs to the structure may be required subject to site conditions. The basic suite is comprised of structural profiles, spigots, pressure plates and thermal isolators. A wide range of caps allows the designer to select from a variety of aesthetic solutions.

Alternative silicone pointed and frameless vent options are also available- Latitude, SSB and SP. A further unitised modular option is available using a Cassette. Various other bespoke profiles can be produced allowing architects to achieve flexible designs. Glazing options are available for a variety of unit thicknesses.

As with all other products, manufacturing is to exacting standards giving economy with required strength, and many years of aesthetic, trouble-free operation.

2Product Construction

The system is fabricated in “stick” form, is pressure equalised, and self-draining by means of overlapping the transoms onto the mullion members. Water is then channelled to the exterior of the building via the integral drainage chambers within the mullions. Where the transoms connect to the mullions, the joint is sealed by means of a purpose designed transom end seal. The transom members are square cut and fixed securely to the mullions by means of spring cleats design to fit into integral ports within the cavity of the transom wall.

The system is dry glazed using proprietary, high performance captive gaskets internally. All internal gaskets are bonded and sealed during construction, using waterproof adhesive to ensure that a watertight joint at all cruciform connections is maintained at all times.The system is thermally broken throughout by means of a continuous thermal isolator located between a choice of aluminium or thermally enhanced pressure plates and all structural members. The thermally enhanced pressure plate is held in place by aluminium stitch plates. The pressure plate is retained by using stainless steel self-tapping screws.

Carefully designed fixing brackets have been developed to allow a secure and simple fix so that all loads can be transferred back to the building’s main structural form with ease.

3Materials

Aluminium profiles are extruded from aluminium alloy 6060T6, T5 or T4 complying with the recommendations of BS EN 12020-2 / BS EN 755 Parts 1 to 9.

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

1.      Anodised to BS1615 or BS3987 or BS EN 12373-1

2.      Powder organic coated to BS6496 or BS EN 12206-1

Metal Technology's powder coating is produced to Qualicoat standards.
The System 17 curtain walling can accommodate a different colour/finish internally to that used externally.
