Most homeowners are ready for new patio doors when they stop working correctly. Even if your current patio doors are still opening and closing fine, there are many other reasons to consider upgrading. You can choose to have bi-fold or sliding glass doors fitted, but you need to know both come with pros and cons.
With bi-fold doors, you realize that they will be closed most of the time.
However, you can have one independent door that is easy to use. The best thing about this kind of door is that it can be stacked to create a massive space opening up to your patio.
On the other hand, a sliding door is ideal if you have a small patio that cannot accommodate the stacking of bi-fold doors. Sliding doors are easy to use, but the thing is that you will never have the full aperture open like in the case of bi-fold doors.
This can limit the amount of lighting that comes into your space.
Ultimately, both doors are great options. You need to consider which would work best based on different factors, including available space.
