Introduction EFP 55 Sliding Window & Door systems.

EFP 55 Sliding Window & Door systems enables the construction of attractive and & high quality Sliding 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 55 Sliding W&D range is a pressure equalised, fully drained, if desired a thermally broken system which consists of 55mm or 100mm and 148mm deep frames.


Specification summary continued:

  • GlazingThe system is glazed from the inside. 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 / Sliding Sash Glazing depth is 38mm, standard glazing thickness from 4 to 28mm
  • Thermal insulationStandard configuration: Class 3.0 in accordance with DIN 4108 (>4.5 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 3.0 DIN 4108-4 Table 3
  • Sound insulationDepending largely upon the glass specification, generally the window framing reduces the figure by 3-4db (A)
  • MaterialsThe system is constructed from extruded aluminium profiles, using alloy 6063 complying the requirements of BS 1474.
  • 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 good levels when manufactured, installed and glazed to EFP recommended procedures.
  • Size limitationsThe size limitation of the system depends mainly on Sash/vent sizes and on the (mullion) vertical member used to suit the span, spacing and wind/dead loads, which are specific for each individual project
  • Sliding Window & Door Types The systems consist many different window types like: 1, 2, or 3 track sliding with fixed & sliding panels, several combinations can be made.
  • Hardware or Ironmongry (Rollers / handles / locks etc) These has been designed around and do comply with most commonly used European brands.
