The presented design arrangements are the standard (no extra charge) for every window product line.

1. PVC Profile (Frame and Sash)

• durable, snow-white

• smooth surface easy to care for

• several chambers (3-6 depending on the shape type), ensuring good heat-insulating and sound insulating qualities

• greyish aesthetic gasket made of a high quality material (weatherproof and UV-proof) ensures window tightness

2. Steel Reinforcement

• robust galvanized steel profile with wall thickness ranging from 1.8 to 2 mm, closed profile in the window frame, in the sash – channel bar

• ensures window rigidness and stability, warp resistance and hinders jemmying the window

3. Windowpane

• heat-insulating (overall heattransfer coefficient Ug=1.1 W/m2K); combined: two glass sheets with inert gas (argon) interlayer insulation

• suppresses noise effectively (sound insulation at the level of Rw=32 dB)

• crystal clear – allows excellent use of the solar light and solar energy and does not cause a ‘dirty curtain’ effect.

4. Window Fitting

• modern microventilation in each tilt/turn sash

• sash lifter which also prevents wrong position of the handle

• tilt interlock prevents selfclosing of a tilted window due to the wind or draught

• electroplated silver coating effectively protects the fitting from corrosion

• anti-jemmying catch on the window stile provides basic protection against break-in
