Fiberglass Windows Cost
Fiberglass windows cost range from $800 to $2000 per window installed. This is a big range - let's say a good fiberglass unit can be installed for $650 - this would be for a Marvin Infinity with no upgrades and nothing too complicated with the installation. Fiberglass is an excellent option for homeowners who want a window that performs well, likes the look of wood but can't afford a woodclad option and/or doesn't want to deal with have the maintenance issues that go along with wood frames.

Basics Of Fiber Glass Windows
Fiber glass windows are sometimes considered composite, meaning they are mostly fiberglass - but also comprised of other materials (often proprietary blends) to create a strong and durable frame. Their performance numbers are probably not as good as the best vinyl windows, although there is debate as to which material holds up better in the long run.
Fiber glass will typically run 35% more than vinyl. They will typically run 25% less than wood clad. So they are right in that middle of the road price range. However, because they are considerably more expensive than vinyl windows, they are often outside of many homeowner's budget. Fiberglass vs Vinyl Windows

Installation Costs
Simple inserts will run $75 to $150, while full tear outs can go as high as $500 per opening. The only way to really get the cost of installation for your project is to get some bids from local contractors and see how they price it out. Don't just get one bid, make sure you have three or four bids from different companies to make sure the install price is reasonable and in line with the others.
