NRGY SGC

Intermittently structurally clamped curtain walling

NRGY SGC is a low-cost alternative to full structural silicone glazing, creating a flush glazed appearance using concealed toggles.

Description NRGY SGC

  • Economic alternative to traditional structural glazing
  • Based on the transom-transom connection principles of NRGY ST
  • Available as mullion drained only
  • Single (asymmetric) and double (symmetric) toggle brackets
  • Single glass bonded to aluminium carrier frames
  • Specialist double and triple glazed units (high thermal performance)
  • Aluminium U-profile set in edge seal, for central clamping
  • Continuous recess in edge seal, inner pane clamping
  • Silicone or gasket seal between glass
  • Compatible with NRGY IT windows
  • Alternative solution for HL and VL (concealed glass retention)

Performances

Air Tightness

> AE 1650

Air Tightness

Air tightness refers to the amount of air that will travel through a window or door system in its closed position, both under positive and negative pressure.

Water Tightness

> RE 1650

Water Tightness

The test applies specified amounts of water spray to the outside face of the window (combination) while incrementally increasing the air pressure. The result defines the test pressure, time and position of any water infiltration.

Wind Resistance

> 2000 Pa

Wind Resistance

The test applies a series of positive and negative test air pressures. Measurements and inspections are made to asses relative frontal deflection and resistance to damage from wind loads.

Thermal insulation

U value < 0,73 W/m2K

Thermal insulation

Results of the calculation of the thermal transmittance of frame profiles and of the linear thermal transmittance of their junction with glazing or opaque panels

The NRGY concept

Like all Sapa products, the NRGY fa├žade system is focused on simplicity and minimalism, with a lean towards saving time.

An innovative concept, with modular flexibility in both appearance and performance, where framing widths of 52 mm and 62 mm can be connected to one another; where the external skin can be stripped of its aluminium coat for an all glass appearance; and where the insulative core of the system can be enhanced to meet the thermal demands of future buildings.

  • an intelligent profile shape, combining strength with minimal width
  • straight cut production, fused with patented dry connectors
  • factory assembly
  • screw free connection system
  • integral connection pins
  • 3 step approach to thermal performance
  • self sealing gaskets
  • faster glazing through permanent clamping components
  • choice between mullion or pane drainage
