As we have posted, we are big fans of Marvin’s fiberglass window line, Integrity Windows. We were therefore delighted to read Integrity’s announcement that their finish (exterior and interior) was rated as the most durable finish you can find on a composite (fiberglass) material. Moreover, the fiberglass finish was rated equal to their finish standard on their aluminum-clad line, itself best in class.
No other fiberglass window has matched Integrity’s quality standard.
For our customers, this means they can enjoy the peace of mind of knowing that their window finish will hold up better than the alternatives and contribute to a long, high quality life cycle.
