When it comes to replacement windows, the improvements seemed to come all to fast during the early 2000′s. However now most of the advancements have slowed down. For clients living in the southwest region, dual pane with Low-E3 and Argon Gas should be standard features these days. However, for clients living in the northeast region, triple pane is not a bad option. Also, Krypton Gas may be well worth the extra money to handle those extra cold climates.
All and all, a high grade, energy efficient window is certainly worth what the homeowner pays for it. Though most homeowners don’t know various options and rarely know that the few extra bucks it costs to upgrade to Low-E and gas is well worth the investment. That’s where you the contractor comes in. You must educate the homeowner that saving a few bucks in the initial cost may cost them a lot more down the road in the extra energy costs.
