From Eloyd’s over 21 years of experience in the window and door industry, sliding door is one of the most demanded door types in high-end developments due to its various benefits. With modern buildings' requirements for high performance and visibility of sliding doors, especially high-end buildings with high story height and large space have higher door performance requirements, ordinary sliding doors can no longer meet the requirements of such designs. Another popular alternative in use in prime real estate is the lift and slide door, a model largely derived from sliding doors but with an emphasis on ease of use.
So what are their differences and advantages? Here is a comparison to guide you through your selection.
The Difference between Lifting Sliding Door and Sliding Door
In terms of appearance, the difference is not big, but the lifting sliding door is classified into the high-end sliding door category, mainly used on relatively large heavy sliding doors. The difference from ordinary sliding doors is the hardware used in the lifting system, such as Lifting handles, transmissions, front and rear pulleys, these are different from ordinary sliding doors, so lifting sliding doors are more flexible in movement, higher in bearing capacity, better in sealing, larger in opening and better in permeability than sliding doors.
What is a lift sliding door?
The external structure of the lift sliding door consists of an outer frame and a door leaf. Its hardware accessories mainly include handles, transmissions, and front and rear pulleys. Lifting sliding doors makes full use of the principle of leverage. By turning the special long arm handle, the lifting, fixing, opening, and closing of the door leaf can be controlled. When the door handle rotates down 180°, the pulley falls on the track and lifts the door upward through the transmission action with the connecting drive, the door opens and slides smoothly over the track; when the handle rotates up 180°, the pulley Separated from the lower frame track and the door leaf is lowered, gravity makes the strip stick to the door frame for instant and efficient sealing.
How to achieve lifting and pushing and pulling?
How do the lifting sliding doors lift and slide? It relies on the whole hardware system,which is mainly composed of handles, transmissions, pulleys, lock points, and lock seats. The lifting and lowering function of the door leaf is to apply torque to the handle, drive the transmission rod, and the pulley moves along the direction of the lifting mechanism to realize the lifting and lowering function of the door leaf, and can also realize the door leaf to any position and lock it.
Handle
A good handle can be made of zinc alloy material, with good surface gloss, anti-corrosion, and anti-rust treatment on the surface, delicate and smooth without impurities. The handle operation is smooth without obvious gaps and shaking, and it is different from the sliding door handle which can be locked by rotating 90° by the door edge. Lifting the sliding door handle is rotated 180°, the door leaf can be slid to any position and locked, preventing children from getting hurt while playing.
Transmission
The transmission is an important part of connecting the handle and the locking assembly. The quality of the transmission determines the smoothness of the handle opening. The material should not be easy to corrode, and the stability of the system transmission should be considered. Common lift sliding doors on the market have safety problems caused by rapid rebound when the handle is turned, which may cause injury to children. Therefore, it is necessary to choose a driver with a buffer function. When the door leaf is opened to locked, it can buffer the door leaf from falling and prevent the handle from rebounding; when the door leaf is locked to open, it can play a boost. The function of the door leaf provides convenience for the smooth opening of the door.
In addition, you should select a good design for the lock point and the driver. One driver is equipped with at least 4 lock points. Closing the door leaf can realize multi-point locking, which ensures the sealing, thermal insulation effect of doors and windows, and anti-piracy performance. The locking point is hidden in the door leaf, and the lock seat is also installed in the notch of the door frame. There is no obvious protruding profile to avoid the risk of scratching clothes and children and the elderly due to accidental collision.
Front and rear pulleys
The pulley of the sliding door can only slide left and right, and the pulley that lifts the sliding door can be lifted up and down in addition to sliding left and right, which is the reason for the good sealing of the door leaf. Due to the large door leaf of the lifting sliding door, it is necessary to choose a pulley with reliable material, large bearing capacity, and good wear resistance. The high-quality front and rear pulleys are made of thicker stainless-steel panels, which can effectively ensure the strength of the pulleys. In addition, you can also look at the quality of the wheel bearing. A good bearing has a fine surface and smooth rotation. Another important point is that the internal structure should be geared, which can effectively reduce the lifting force and improve the service life. A good pulley can be pushed and pulled repeatedly hundreds of thousands of times.
In addition to manual control, the CMECH lifting sliding door hardware system canalso be electrically controlled. You can sit on the sofa and press a button to control the opening and closing of the door.
Lifting sliding doors can not only withstand the opening of ultra-wide heavy-duty doors but also have many advantages compared with ordinary sliding doors.
Energy efficiency benefit
With tracks installed at both the top and bottom of the lift and slide door frame, the connection between the frame and panels is airtight. When the door is locked, the rubber strips surrounding the frame create optimum sealing. Thus, preventing the escape of cooling or heat.
Safety and security
In general, the lift and slide door frame is more durable and with enhanced wind pressure resistance.
Furthermore, it serves as an anti-theft system. When the handle is moved to the closed position, it engages the locking mechanism and also sets down the full weight of the panel to the frame. As a result, this significantly improves force entry resistance and makes a good balcony or patio door.
Another benefit of the lift and slide doors is their thoughtful design to prevent childhood injury. As the door can be lowered and locked at any position, it prevents children from accidentally operating the door when not monitored by adults.
