I did contact Simonton management,and they
came to our home, and this is what they said
"look at it this way, windows are like snow-
blowers, they range from 3 hp to 15 hp, they all
do the same job , remove snow, some people could
be happy with a 3 hp, but in the event of a huge
snowfall, a 3 hp wouldnt do a very good job.
In the world of windows, ours(Simonton) are
3 hp windows." I dont think I can explain it
any better than the Management of Simonton.
