Best fiberglass and Best Vinyl Double Hung Windows

#1 Post by mike71 »

I am a builder in Western Virginia and we are looking at using different windows in our next 5 houses.
Who makes the best fiberglass windows in double hung?
Who makes the best vinyl window in double hung.

I am not concerned about price. Just superior quality and thermal performance.

Thank you.

You will probably get a myriad of different answers to that question and there is certainly and aesthetic component to that determination that you will have to fill in.

In the Fiberglass arena, my list, in no particular order, would consist of Pella, Milgard, and Inline.

In vinyl, my list would consist of Soft-Lite, Okna, Simonton, Sunrise, and Force V.

Both the Softlite Elements and Okna have U-Values on double hungs as low as U-.15. I am not sure about Okna since it is not sold in my area, but the Elements is available as an insert replacement window or can be ordered with an integrated and welded nailing fin. (integrated means it doesn't snap into the window via a groove). The fin is part of the extrusion. Sunrise also comes this way.

Force V does not come with an integrated fin but is available with a very labor intensive add-on fin and J-Channel assembly. Only the most experienced and detail-oriented should try to install these windows with this fin system.

All the windows in my list are available as either retrofit replacements or with a nailing fin (so integral as Windoww4U mentioned and some not).
