Reviews & Rating uPVC Twin Sash Window


Our experience with the soundproof windows from AIS Windows was excellent. The installers were well-trained professionals and behaving decently during the job. They used to clean the site every day after work. It was amazing to see the final finished product in its place. Fantastical job overall!

I needed some privacy windows for my office. I called AIS Windows, their experts came and suggested the best suitable solutions to me. The installation began the next day and the technicians from AIS windows were awesome in their work as well as behavior.
