Sliding doors are going to offer the most unhindered view of the outside.
Sliding doors vs bifold doors for closets.
Both types of closet door options work well enough initially but are prone to problems during normal use.
Bifold closet doors with 3 1 2 louvers what if bifold doors are my only option.
So if your closet is 72 wide using 2 doors each 36 wide will cost less than using 4 doors each 18 wide.
Since wider doors are typically hung as sliders this does make sliding closet doors less expensive.
However bi fold doors only offer a full view when completely open.
If you want reduce the amount of frame and maximise glass sizes making the most of the view go for sliding doors.
These points will help you decide whether bi fold doors or sliding doors are best for your project.
In choosing between bifold and sliding closet doors the main factor to consider is the size of your closet opening.
Keep in mind that sliding doors can be removed if you should need full access once in a while.
If you need full access to the closet or you just want to be able to open the doors and see everything at once then bifold doors are your best choice.
If you have strict thermal value requirements you may need to opt for sliding doors.
