I can share with you my experience of using sliding glass doors in a home that I bought. At first, I didn't really like this design solution, but then it turned out to be very convenient. Firstly, such doors are an excellent design solution for small rooms and secondly, due to the fact that such doors are glass, there is enough natural light in my living room, which makes this room very cosy. The only drawback that I have encountered in six months of living in a new house is that the previous owners didn't hire a handyman to do the sliding glass door repair. But I was able to find a really good company specializing in providing such services and quickly fixed the problem.
