Marvin Fiberglass and Fiberglass Windows
Marvin fiberglass and fiberglass windows are designed to create a stylish window that not only looks beautiful but performs at the highest levels of thermal efficiency. Available in two varieties of fiberglass – Ultrex®, as well as Marvin’s patent-pending High-Density fiberglass – Marvin is certain to have the perfect fit for your living space. With its minimal conductivity, fiberglass is one of the best insulators among window-frame materials. Available in Marvin’s Essential Series, in every window style from double hung to specialty, fiberglass shrinks and expands at the same rate as glass, allowing for a tight seal and long-term stability which guarantees that it will perform like new for decades.

  • Freddy Villamarin Danbury
    Freddy Villamarin, Danbury CT

    We are so happy that we saw their truck doing work in our community and saved their number! After researching and comparing pricing with other companies, it was an easy decision to go with them for such a big project. There was no gimmicky sales pitch, just honesty and upfront information. Absolutely top notch service and company! They went above and beyond and they were very helpful and caring throughout the whole process. Their crew are all so nice, professional and very efficient with their work. This is a company you would want to keep in your contacts for future projects.

    The team was great and thorough from the initial meeting to the final inspection upon completion of our project. John and Greg were very helpful with the initial communications and Chris did a great job leading the installation.

    Elad Green, Hawthorne NY

    Excellent service from start to finish. The whole team, from Greg on the phone to John in person setting up the window install, to Angelo and his team on the install. Couldn't have asked for a better setup. If you're at all thinking about having windows installed (I can't speak for doors since we only replaced windows) look no further.
