General Aluminum Corporation review: Windows loose vacuum between glass panels causing moisture accumulation

Have had these windows installed since I purchased my house new in 2006 and already had six of these replaced and now are in need of replacing an additional five defective windows. The six defective windows were replaced after 12 years of service at a cost exceeding $1200 (ridiculous). The windows replaced were damaged as a direct result of UV damage caused by southern high summer temperatures.
