Historic-type window (Chamfered) EV47/EV47

Historic-type window (Chamfered) EV47/EV47 the inner sash is opening inwards, the outer – outwards. Both sashes are 47mm thick, both with single glazing (usually 4mm, up to 8mm thick glass is possible), which is sealed using silicone. The inner sash has a rubber sealing contour which improves the thermal and sound insulation of the window. Sealing may not be applied to the outer sash to prevent formation of condensate in the space between sashes and the glass from sweating. For the inner sash, we use the standard Roto NT fittings, the outer sash features special hinges and hooks, which similarly to Scandinavian outward-opening windows, allow locking the sash opened for ventilation. The historic windows usually have the decorative T-shaped handles.

Thermal conductivity coefficient of the window UW=2.2 W/m2K (calculated according to DIN EN ISO 10077-1), sound isolation 28-30 dB.
