There are no unfinished or exposed edges and no internal projection of transom and sash sections. The top and Bottom sash rails are concealed within the sill and frame.
The sash sits completely inside the frame which resists rolling off the top and bottom sash rail under high wind loads, with increased daylight opening.
Heavy duty double rollers are standard on all wintec sliding windows which last longer and operated smoother than conventional types.
Our handles are also ergonomically designed for ease of use especially for the elderly and disabled. The handles operate in the direction of the sash movement and are available in four colours.
Additional options include:
Multi-position vent locking.
