The question comes from a home owner’s repair and renovation online discussion forum:
Do you really need the insulating glass in vinyl replacement windows? How much good does something you can’t even see even do? It seems like I’m paying a lot of money for nothing!
The fact is you can’t see either argon or krypton, the gasses most commonly used to insulate vinyl replacement windows. Alside Windows ClimaTech Insulated Glass Package uses argon gas, sandwiched between low-e glass. It’s essential for insulated gasses to be invisible, because most homeowners like to be able to see through their windows!
Industry research tells us that argon and krypton add significantly improve the energy efficiency of vinyl replacement windows. There can be an up to 20 percent improvement in a window’s insulating value (often referred to as the R factor) when a unit integrates insulating gas.
This is substantial! With ever increasing fuel prices driving the costs of heating our homes higher and higher and higher, we’re all looking for ways to save energy. If installing vinyl replacement windows is part of your effort to save energy, it’s critical that you select the best vinyl replacement windows to help you do that!
Saving a few dollars per window by forgoing insulating gas might seem like a wise decision — until you consider the long haul. These windows are going to be in your homes for years and years and years. Don’t you want to save the maximum amount of energy possible that whole time? If you add up the cost of energy that escapes through uninsulated windows over the course of that time and compare it to the price difference between gas filled windows and those without gas, the initial price savings doesn’t seem like such a good deal anymore!
