Advantages

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.

Glazing

EPAL imports glass panes from the world’s leading glass producers.

Crank-Out 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.
