If you are like me you're already thing "how can this guy proclaim that his choice for replacement windows is the best?" Stay with me here and I'll make my case. I'll back it up with independent testing data too.
Preservation Replacement Windows feature EnergyMaxx10 high performance glass. Glass is 80-85% of the window unit so it's probably the most important piece of the energy efficiency puzzle.
EnergyMaxx10 uses the SST Warm Edge Spacer System (the spacer system is another subject soon to come on this blog). It also uses two chambers of krypton gas rather than argon. Krypton gas has two and a half times the insulation value as argon, commonly used by other manufacturers. It is more than 100 times more expensive but when the gas chambers total 1 full inch and there are two chambers rather than one you get a heck of a U-factor for the glass in your replacement windows.
One other point that will put things in a context that is easy to understand is that Preservation Replacement Windows already meet the proposed Energy Star Standards for 2015 . It is the first window to achieve that level. In fact, the "off the shelf" Andersen, Pella, and Marvin Windows don't even currently meet the 2012 proposed standards.
The Twin Cities Preservation Replacement Window Dealer of Distinction is Northland Home Exteriors. Northland is located in Oakdale and Forest Lake, MN.
My next blog will be about the SST Warm Edge Spacer system and what it means to the energy efficiency of replacement windows.
