My factory is in Canada (22,000sq/ft)
It is not cheap to manufacture here. GM glass is a "LOW-E Solar Temper 20-30%" type glass.
Very common, very cheap.
Our retail price - $4.70CAN per square foot
Sentinal USA price-$2.40US per square foot
Old Castle price - $2.55US per square foot
DuraMax,
All production of these types are 90% AUTOMATED
and if it takes my guy $50 in labour for a 10 minute job, well....
Soft,
The Hummer's driverside and rearview mirror are Solar reactive, slightly more expensive.
I believe the driver and passenger windows are possibly the same, but doubtful. Hey everyone has to make a buck, I only share this knowledge because this is our forum.
Example: Speedy autoglass aproached us to mfg.
5 specialty winshields for their stock.
-They supplied the mold(to form the shape)
-I charged them $570 each for 5 OR $290 each for units over 50 (they went for 50)and much cheaper over 500units.
-Their supplier charged them $700 each plus 8% wholesale discount.
In return Speedy will retail for about $1000-$1200 Canadian.
My cost to make $45 labour and all.

Like I said, everyone has to make money...some more greedier than others.
He ain't heavy.....
He's ma HUMMER baby!
