Are uPVC windows a good or bad idea at 7000' elevation and high solar insolation?
I am considering the purchase of Intus eForte windows for a new house. The windows would have be transported over several mountain passes up to 11,000 ft and then be installed at 7000 ft. This would require pressure relief valves that would vent the argon gas. Does this degrade the performance of the PH certifide window and would it become uncertifided? Also, the dealer recommends white or similar light reflective colors in Southwestern states due to the fact that darker colored PVC will expand and contract more causing more stress on the IGU to frame seals since even white PVC expands and contracts more than glass. White PVC is not what I want in the new house. (I tore out the white PVC windows in the current house and installed aluminum clad wood) Even though Intus is reasonably price, a house load still is a considerable investment and I'm very concerned about the two negative mentioned. Any one have experience with this problem?
