We had Western moving glass walls installed in our new home three years ago. We love them! Soundproof and tight fitting, they slide with ease — and best of all, we can extend our living area to the outside just by sliding them open to our patio area. My mini dachshund Lucy recently chewed the small white plugs inserted into the bottom of the panels (for excess to the door adjustments) as she was teething. I emailed customer support and what do you know, my email was answered immediately and they were sending new rubber inserts to take care of the problem! Great customer service. Thank you!
