Four sided structural silicon glazed

EFP 50 FSS and EFP 60 FSS CURTAIN WALL system enables the construction of attractive 2 sided structural glazed curtain walling, with the benefits of slim sightlines.

This thermally insulated system consist of many of standard profiles and many custom made profiles are available up on request.

Specification summary:

EFP 50 FSS is a pressure equalised, mullion drained, thermally broken curtain wall system which consists of 50 mm wide mullions and transoms.

The external vertical and horizontal sightline (Joint seal) is 20mm. The joint seal is made of extruded EPDM or Silicone, compatible with most silicone sealants, optional this joint can also be made out of silicone sealant. Various FEATURE cover caps are available for this system.

EFP 60 FSS With an increasing demand for larger vertical and horizontal spans a range of high static value mullions and transoms with a sightline of 60 mm.

  • One substructure for all curtain wall types (RCW-TSH-TSV-FSS)
  • Use of same components and gaskets

The system is glazed from the outside. Glass should conform the requirements of BS 6262 for thickness and type, in terms of wind resistance, safety and security.

The system is mullion drained, achieved by meeting the requirements of “Ventilated and drained glazing system” as specified in BS 6262

Standard configuration: Class 2.1 in accordance with DIN 4108 (2.0-2.8 W m2 K) or EN ISO 10077-1. The thermal transmittance (Uf) W/m2 K, is depending on the insulator strip, this as calculated as per EN ISO 10077-1. Comparable with class 2.1 DIN 4108-4 Table 3

Depending largely upon the glass specification, generally the curtain wall framing reduces the figure by 2dB(A)

The system is constructed from extruded aluminium profiles, using alloy 6063 complying the requirements of BS 1474.The thermal barrier system is achieved by means of PVC/PP extrusion.

Any instructions regarding the manufacture and installation of the system must be strictly adhered to.

Glazing vision strips are made of EPDM conforming to BS 4255 Part 1.

The system will achieve the following criteria when manufactured, installed and glazed to EFP recommended procedures.

  • Air permeability: BS EN 12152 – Class AE 750
  • Water tightness: BS EN 12154 – Class RE 750
  • Wind resistance: BS EN 13116 – 2400 Pa design – 3600 Pa safety
  • 2400 Pa is dependent upon correct mullion and transom selection to suit span and spacing by project.

The size limitation of the system depends mainly on the mullion/transom members used to suit the span, spacing and wind/dead loads, which are specific for each individual project.
