I was told that fiberglass is stringer and expands and contracts at the same rate as glass, this causes better seal integrity on the thermopane glass. Are the fiberglass windows that much better? and if so, are they worth the extra cost?

Fiberglass is indeed a bit stronger than vinyl, but I have been installing vinyl windows for 30 years. Windows I have installed in my mother-in-law’s house 28 years ago are still as good as the day they were installed. No problems.

The expansion/contraction ratio between the fiberglass and the glass pane is not important. The seal between the stiles and the windowpanes are rubber and the glass can expand and contract at a slightly different ratio with no adverse effect.

Fiberglass windows do have a few advantages over vinyl but they are not of major importance in my opinion. My philosophy is if you can afford them use them, if not don’t. I don’t think you will regret your decision.

Heavy D. The devil is in the details. The fiberglass surface must be painted and maintained just like wood. vinyl will give you a lifetime of quality if you make a good decision. There are vast differences in quality as there are in wood, aluminum and any other home improvement product..look for a strong guarantee.

For what it's worth (maybe nothing) one of the largest installers of replacement windows in this area has stopped using fiberglass because of what he says are some issues with it, especially when compared to vinyl and wood.

Having experience with windows over 30 years I found that fiberglass is far superior to other materials over the long term. Vinyl is stucturally weak, wood requires maintainance,and metal is a conductor causing heat loss. Fiberglass has the best attributes of the above without the drawbacks. Higher initial price, but lower cost over time because they last much longer and maintain energy efficiency.
