The installation site of the apartment veranda folding door was replaced with a folding door from the Miseo window while you were currently living, not the interior construction before moving in.In this case, the construction method, also known as One Day construction method, is carried out. Since wallpaper, floorboards, interior accessories, and home appliances are already located, the general construction method that goes along with the demolition work is highly likely to break down, and it may be inconvenient to live because the installation takes longer.

The existing shot seat is a method of removing windows that have not been demolished and installing folding door lower rails on top of the existing shot seat to proceed with construction.Since there is no time to remove the existing shot seat due to the construction method that does not require demolition work, the construction time of the folding door can proceed quickly to complete the construction work on the same day.In addition, there is no additional cost of demolition because the existing shot seat is not removed, and there is no damage (damage) to the wallpaper, floorboards, and appliances that are already under interior construction.​

Even if the lower rail is inserted on top of the shotsheet, the lower rail will not be higher, but the height of the existing frame will be maintained so that access and passage will not be inconvenient.​
