Bvwindows
Hi everyone,
I am building a new house and am choosing windows. My builder uses a brand/model called "School House". Has anyone ever heard of these? Or is there a website I can go to to look for these windows?

Im trying to educate myself before I make any decisions.
Thanks!

Your windows are a major expense and a major energy savings (or waste) in new home construction. I would not rely on the brand the builder suggests without really looking into the details of that brand. Check out the construction specifics of the frams and the insulating glass. Then look at the warranty. An 'inexpensive' window is not a bargin when you have to replace the glass after a couple years or find that the construction allows cold to transmit through the frame or glass.

Sorry, I have not heard of that brand and, as you know, there does not seem to be any info on them on the web. Many times contractors tend to automatically supply 'contractor grade' materials. Just what you need in windows depends on your location (climate) and the layout of your home (south & west facing windows vs north & east). In southern climate you may be more concerned with heat reflection while, in colder climates, heat retention may be more important. In extreme cold, the heat transmission through the frame can be very important. Wood has a very good insulating factor but requires more maintenance. Vinyl or clad may better meet your needs. Even in warmer climates double insulated windows are a good idea and 'low e' is worth the investment in most cases. Also, the house itself has a lot to do with your considerations. South & west windows should have sufficient overhang to keep out the summer sun while allowing more exposure in the winter. Personally, I would stick with a better known 'brand name' with as long a warranty as possible.

I agree with you wholeheartedly. You never know though, one of these smaller companies could be making a competitive window.
If I find out more I'll post it up.
Thanks,

I found some information.
I took two windows of the same size & features, one School House and one Andersen.

School House:
NFRC Certified Total Unit
Thermal Performance Value, Unit "R" = 0.50
NFRC Certified Total Unit
Solar Heat Gain Coefficient = 0.51
Air Infiltration Rate (cfm/ftª) = 0.09

Andersen:
NFRC Certified Total Unit
Thermal Performance Value, Unit "R" = 0.49
NFRC Certified Total Unit
Solar Heat Gain Coefficient = 0.58
Air Infiltration Rate (cfm/ftª) = 0.09

So they are very close in the Thermal Performance, and the School House has a better margin in the Solar Heat Gain Coeff.
And the Air Infiltration values were the same.

So far they dont look too bad.

Please understand that the NFRC only rates a window's performance.
While standards are being developed to rate durability, they are not in place now.
Therefore while two windows may have similar performance ratings the only guarentee for long life, is the reputation of the manufacturer. You normally do not go wrong with investment quality windows suxh as Andersen, Pella, Marvin or Pozzi.

FYI,
These are manufactured by a company called Kasson & Keller. I have spoken to several people who have them in their home and they all say they are quite satisfied with their performance & build quality.
