The improved structural analysis enables panels to feature a maximised glass surface. The new design meets all aesthetic requirements, offering extensive scope for design. Further advantages are offered by an optimised thermal transmittance coefficient and reduced costs thanks to frame removal in the fixed sash.
ATRIUM® HS guide track concealed: Comfort functions secretly impress
The top concealed guide track is milled flush into the frame. Whatever the sash weight, this track guarantees that lift and slide doors can be fitted and moved easily, helping to provide maximum outlook to the exterior. A special type of window is thus created which blends into living spaces, providing an aesthetic appearance.
