Description

Self-supporting stick aluminium curtain wall system composed by a grid of mullions and transoms with a visible width of 52 mm. The main feature of this system is a total glass aesthetic in the front view and the same aspect, whether with fixed lights or with top hung openings, both from the exterior and the interior.

Features and benefits:

  • Curtain wall stick system composed of a grid of mullions and transoms constructed from aluminium alloy 6063 T6.
  • The glazing is glued to an aluminium frame using structural silicone. The fixing of the set glass-frame to mullions and transoms is via clips.
  • Attachment of horizontal and vertical profiles is set through unions performed with transom connectors fitted with dilatation joints.
  • Thermal bridge break is set by stackable isolators constructed from polyvinyl chloride (PVC) which allow the different glazing thickness.
  • Optional internal reinforcement profiles for configurations with high mechanical requirements.
  • Optional complementary elements such as solar protection louvres fixed by brackets may be added to the curtain wall in the exterior.

Standard product features

Material:

Aluminium alloy 6063 T6 profiles.

Profile thickness:

  • Mullions: 2.1–3 mm.
  • Transoms: 2.1 mm.

Sight line:

52 mm (mullions and transoms).

Maximum glass unit weight:

350 kg.

Gaskets:

Water-tightness is ensured by a first barrier composed of an ethylene-propylene diene monomer (EPDM) gasket which is installed around the perimeter of each module, and an interior set of cuttable joints constructed from ethylene-propylene diene monomer (EPDM), with the possibility of using vulcanized corner cleats in the junction between mullions and transoms.

Drainage system:

Composes up to three levels of drainage, allowing the evacuation of potential condensation water from the transoms through the mullion channels to finally drain using deflector blocks (pipettes) as elements of evacuation.

Thermal transmittance:

Curtain wall (Ucw): ≥0.7 W/m²K.

Performance (based on nine panels, 3 x 3.5 m):

  • Air permeability (to BS EN 12152): Class AE.
  • Water tightness (to BS EN 12154): Class RE750.
  • Wind resistance (to BS EN 13116): Complies (Design wind load 2000 Pa/ security wind load 3000 Pa).

Product Options

Opening elements:

All opening elements have structurally bonded glass and the water-tightness is ensured by an ethylene-propylene diene monomer (EPDM) joint system. Friction stays are constructed from stainless steel, allowing maximum dimensions of

2500 x 2500 mm (w x h), 180 kg maximum weight.

Fixing brackets:

Connection of the curtain wall to the substructure is performed using aluminium fixing brackets. Different configurations are available including bottom fixing brackets, head fixing brackets, fixed and sliding bearing point brackets, etc. Contact manufacturer for more information.
