E32 is a sliding aluminum system that is considered as the most economically advantageous solution in its category and constitutes an ideal choice for replacing old frames.

With a smart design, simpler components, and the lighter sections in its category, the E32 system offers easier and faster assembly and installation compared to other equivalent products. Therefore, the constructor benefits from the reduced installation time and an unhindered task flow.

The system uses sashes with a width of 32mm and polyamides from 16mm to 28mm, which are ideal for medium sized openings. The system’s innovative design, with features such as narrow tracks with a width of 76mm to 107mm and a height of 31mm, makes it an ideal choice for the replacement of old sliding in-wall frames. The inox track at the bottom of the window frame guarantees the frame’s easy, smooth and unhindered operation.

The frames of the EPAL Ε32 range have the following characteristics:

  • Single or double glazing with spacers between 10 – 22 mm
  • Profile with a thermal break along its entire length.
  • High thermal transmittance (Uf= 3.2 W/m2.K)
  • Heavy-duty mechanisms manufactured by the German company HAUTAU, which secure the front part in up to 4 points, offering security and functionality.
  • Accompanied by hinged and parallel screens.
  • High watertightness
  • Constructed using specific materials and fittings which fulfill predefined high-quality specifications.
  • Manufactured under controlled production processes that ensure consistently high quality.

The E32 range of sliding frames ensures:

  • Comfortable and durable operation for frames of large dimensions.
  • Customized solutions that meet all requirements
  • High resistance to mechanical stress during use and very good functionality.
  • Superior quality of electrostatic powder coating with a wide variety of color options.


E32 sliding frames are installed by expert technical staff on any surface, using special fittings and insulating materials that ensure a perfect fit.

  • Single-sash, two-sash, three-sash and four-sash
  • Parallel, meeting stile, in-wall
  • Integrated screen and/or shutter

At EPAL we use glass panes by Guardian and Saint Gobain, two companies that are world leaders in glass production. EPAL E32 is a sliding frame system with double or triple thermal insulating glass panes that achieve a thermal transmittance Ug = 1.00 W/(m2⋅K) for double glazing and up to 0.7 W/(m2⋅K) for

triple glazing, as well as high levels of sound insulation

The sections of the aluminum profiles of the E32 range with a triple track (parallel with a screen) have the following technical characteristics:




Technical characteristics of the frame and sash:


Maximum sash width 1600 mm
Maximum sash height 2300 mm
Maximum sash weight: 90kg



Air permeability: Class 4
Watertightness: Class 7A
Resistance to wind load: Class C3
Thermal conductivity (Uf): From 2,9 W/(m2⋅K)


The aluminum profiles of the E32 range are painted using electrostatic powder coating in the new, state-of-the-art EPAL plant after appropriate surface treatment (preliminary degreasing and chromating), to ensure better paint adhesion as well as high quality and durability.
