I have Inline Fiberglass windows in my home and they are the quality is shockingly poor. The owners of Inline led me on for many months, telling me that they would send someone to fix the substandard windows that they sold me. They never did. The owners of this place are incredibly rude on the phone, interrupt continually and lie through the nose, claiming that they "never received" the e mails. Every time it rains, the water comes right in through my windows and window frames. Outrageous.
