Description
In both cases the aluminium casement window profile glides over a track on stainless steel castors. But in lifting systems the sliding doors are lifted before sliding on the SS track. In its closed position the lifting system is locked, which represents an additional plus point for aluminium sliding doors with respect to insulation and theft prevention. Obviously both systems are fully windproof, water- and airtight. Just like any other Reynaers window or door profile.
