![]() Better water and air tightness, reduced wear and tear There is no additional finger-operated locking mechanism needed, and it will not get jammed over time like many slider locking mechanisms do. The simple turning motion not only unlocks the door, but it also raises the door at the same time. ![]() The substantial and easy-to-use handle of a lift and slide door is also an improvement over many locking mechanisms used on slider doors. With these capabilities, customers who might have avoided larger sliding doors due to the weight of the vent, may once again consider larger vent sizes with the lift-and-slide mechanism. In addition to the added vent clearances when lifted and the protection of the rail from dust and debris, European lift and slide doors also use high-performance bearings in the rollers add to their smooth operation. This innovation translates into three main advantages: Ease of useĪs already mentioned, the lift-and-then-slide design allows the user to open even over-sized vents with the push of a finger. In the closed position, the rail is completely protected from debris and corrosion. Move the handle back in the original position and the rail is lowered, sitting the vent back down on the bottom of the frame for maximum air and water tightness. The door can now slide at the push of a finger. The vent is fully released from its seals and has more clearance from the bottom rail. It can be used with nearly limitless sliding door designs, from conventional two panel setups, to multi-panel, corner-less configurations spanning the width of a house or building.Īs you turn the handle down, the vent is lifted by a pulley system. You have probably noticed it yourself on older slider doors.Įuropean lift and slide doors avoid the issues of regular sliding doors by utilizing a mechanism that lifts up the door before sliding. Over time, as debris and corrosion reduce the clearance even further and the bearings on the rollers wear out, sliding doors become harder and harder to open, especially on larger elements. To maintain sufficient water and air tightness, sliding doors have very little clearance between the rail and the vent, creating significant friction and rubbing of the seals, even on brand new doors. The door is supported by small rollers under the vent which move along the bottom rail. ![]()
