Energy Efficient Windows
What is the most expensive window you can own? If you don't have
vinyl replacement windows from Feldco the answer might just be the
ones you currently have. That's because inefficient windows can
cost you hundreds of dollars each month in heating and cooling
bills compared to what you could be paying if you had Feldco
windows.
You've heard people say, 'close the door, we're not trying to heat
the neighborhood,' you may have even said it yourself, but the
reality is if your home has inefficient windows you are helping to
'heat the neighborhood' each and every day. That costs you money--
money that you know could be better spent on other things.
Just how much money are we talking about? Well, 70% of what you
pay each month for heat and 40% for cooling goes right out your
windows. While no window can stop air loss entirely, Sophia Series
replacement windows from Feldco can stop much of it, so much that
many of our customers tell us repeatedly how much less their
furnace or air conditioner runs immediately after their Feldco
windows are installed. And there's is more to the efficiency of
windows than saving money. There is the improved comfort that you
will feel in your home from the first day the windows are
installed, a comfort that lasts season after season and doesn't
require adjusting the thermostat a few more expensive
degrees.
By creating a tighter seal on the openings of your home, Feldco
replacement windows reduce air infiltration, thereby making your
home more energy efficient. Feldco Sophia Series windows are Energy
Star rated and designed to excel in severe Midwestern weather
conditions.

| U-Factor | 0.35 | 0.29 | The Window U-factor measures heat loss. That is, the resistance of the window glass to the heat flow (it is the inverse of R-Value). This is the most important information about windows in cold climates The lower the U-factor the better. |

Solar Heat Gain Coefficient |
0.40 | 0.28 | The SHGC is the fraction of incident solar radiation admitted through a window, both directly transmitted and absorbed and subsequently released inward. The lower a window's solar heat gain coefficient, the less solar heat it transmits. |
| Visible Transmittance | No Requirements | 0.53 | Feldco Replacement windows' high visible transmittance allows you to maximize daylight. |

Save energy with glass so smart, it can control your comfort
During cold weather, the insulating effect of your windows is most apparent. Typically, 75% of a window is glass. The better insulated your window is, the more comfortable your home will be. The insulating capability of LoE2-270 is a key factor in the construction of quality windows used in cold climates. The dramatic warmth provided means the relative humidity of the indoor air can be controlled and maintained. Proper humidity levels (not too much, not too little) will improve comfort and promote a healthier living environment.
When temperatures rise, ordinary window glass simply welcomes in the heat. LoE2-270 has been specifically formulated to reject the sun's heat and damaging rays to keep your home cool and comfortable. This patented product provides the best clarity and highest performance of low-emissivity glass products, reducing window heat gain by 50% or more when compared to ordinary glass.
