EPAL Crank Out aluminum casement windows

EPAL Crank Out is a new range of unparalleled beauty and thermal efficiency, designed to cover the minimum needs for free interior space.

With swing-out features and a smart design, EPAL crank-out windows are a solution for those who wish to make the best use of their home’s interior space.

• Profile with a polyamide thermal break of 32mm along its entire length
• Overhanging and swing-out typologies.
• Crimp corners
• With ROTO X-DRIVE mechanisms by ROTO Frank, which offer unparalleled aesthetics, high construction quality and superior corrosion resistance.
• EPDM perimetric gaskets for perfect sealing.
• A multi-point locking system designed to operate flawlessly and effortlessly, while maintaining its style and durability.
• A triple-sealing system that prevents the inflow and outflow of air and moisture.
• Constructed using specific materials and fittings which fulfill predefined high-quality specifications.
• Manufactured under controlled production processes that ensure consistently high quality.
• Can be combined with the EPAL range
• Possibility to install an internal screen.

• The EPAL Crank Out range of frames ensures:
  • Exceptional thermal insulation. The EPAL Crank Out system allows the construction of frames with excellent thermal insulation characteristics (up to Uw = 0.87 W/m2K), based on tests conducted in accordance with DIN EN ISO 10077-1.
  • High sound insulation levels: Rw (C; Ctr) = 38 (-2; -6) dB weighted sound reduction index (with triple glazing 6Planistar – 15 – 4 – 15 – 4)
  • High resistance to mechanical stress during use and very good functionality.
  • Superior aesthetics with a wide range of colors and high quality electrostatic powder coating.
  • These protruding windows rotate outwards and can be easily cleaned from the inside, while offering maximum ventilation and an almost effortless operation.

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

EPAL imports glass panes from the world’s leading glass producers.
The 18000 sliding frame systems are equipped with double thermal insulating glazing. The type of glass used is Float glass.  The main combination is a 6mm Planistar glass outside, 4mm glass inside, and a gap of 15mm between the two glass panes (6Planistar – 15 – 4).
This combination has a thermal transmittance of Ug=1.0 W/m2K and very good soundproofing properties (Rw = 36dB, according to ISO140/3-78 tests – Test No. Α6.121.96).

The double glazing is initially glued using two Butyl PIB cords (special plastic glue) which are placed along the perimeter of the aluminum spacer placed between the two glass panes. Butyl PIB is highly resistant to temperature variations: -30°C to 80°C and 160°C (for a limited period of time) and has very low thermal conductivity. The aluminum spacer is filled with desiccants that ensure a longer life for the glass pane.

Apart from the special Butyl PIB glue, an additional two-component glue (polysulfide sealant) is used externally along the perimeter of the glass; this glue is elastic and also highly resistant to temperature variations. In this way, the air between the two glass panes does not come in any contact with the ambient air, therefore it is impossible for the glass to become less transparent over time.

EPAL has been certified by the German Ift Rosenheim Institute regarding the sealing processes of thermal insulating glazing and thermal insulating glazing using gas in accordance with the DIN EN 1279-2 and DIN EN1279-3 standards.

Apart from the standard 6Planistar– 15 – 4 glazing, which has a thermal transmittance Ug=1.0 W/m2K, the E50 range may also include triple glazing with special coatings – Low E soft coating and Low E hard coating.
