Introduction EFP 55tb  Window & Door systems.

EFP 55tb Window & Door systems enables the construction of attractive and & high quality windows & doors, with the benefits of slim sightlines.

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

Specification summary:

EFP 55tb W&D range is a pressure equalised, fully drained, thermally broken system which consists of 55 mm or 100mm deep frames & vents. Various alternative profiles with slim side lines from 24-30-40 and 50mm are available for this system.

The smallest sight line can be achieved using a 24mm wide Frame + 47mm Vent and have externally a typical minimum edge radius of 0.5mm, edge radii for even distribution of the powder coating layer.

Specification summary continued:

  • GlazingThe system is glazed from the inside or outside. Glass should conform the requirements of BS 6262 for thickness and type, in terms of wind resistance, safety and security.
  • DrainageThe system is fully drained & pressure equalised, achieved by meeting the requirements of “Ventilated and drained glazing system” as specified in BS 6262
  • Frame / Vent Glazing depth is 55mm, standard glazing thickness from 4 to 40mm
  • Thermal insulationStandard configuration: Class 2.1 in accordance with DIN 4108 (2.1-2.8 W m2 K) or EN ISO 10077-1 – Uf Value up to 2.5 W/m2K = (EFP 65tb)
  • 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 2.3 DIN 4108-4 Table 3
  • Sound insulationDepending largely upon the glass specification, generally the window framing reduces the figure by 2 db (A)
  • MaterialsThe 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 a Polyamide (PA 66-GF25), glass fiber reinforced extrusion from “Technoform Germany”.
  • ConstructionAny instructions regarding the manufacture and installation of the system must be strictly adhered to.
  • WeatheringGlazing vision strips are made of EPDM conforming to BS 4255 Part 1.
  • Performance / exposure category The system has been designed according to the latest EN standards and will meet the highest levels when manufactured, installed and glazed to EFP recommended procedures.
  • Size limitationsThe size limitation of the system depends mainly on vent sizes versus ironmongery and on the mullion/transom members used to suit the span, spacing and wind/dead loads, which are specific for each individual project
  • Window Types The systems consist many different window types like: side hung, top & bottom hung, tilt & turn glazed from inside or outside, opening inside or outside, concealed vents, horizontally + vertically pivoting etc.
  • Door Types The system consist of many different door types like: single & double doors, structural glazed doors, opening in or outwards etc.
  • Hardware or Ironmongry (hinges / handles / locks etc) The “Euro Groove” system has been designed around and does comply with most commonly used European brands.
