There is a lot of talk about how replacement windows can save you money on your utility bills, but there doesn’t seem to be too much sensible explanation. While we could talk about window efficiency all day long, we’ve tried to keep things simple here.
If you’d like any more information feel free to ask.
In the summer, heat from the sun passes through your windows causing your air conditioner to run more often and your bills to increase. Solar heat gain coefficient (or SHGC) is a number that represents the fraction of solar heat transmitted through a window. The lower a window’s solar heat gain coefficient the less solar heat it transmits. Climates that rely heavily on air conditioning will benefit from a product that has a lower SHGC.
As shown here, our windows with a low emissivity (or low-e) glass option and argon gas fill will outperform a standard clear unit by as much as 49% in the summer months.
In the winter a more efficient window will not let the heat generated by the furnace escape. The U-Factor (or U value) represents the rate of heat flow through a window. The lower a U-Factor the greater the window’s resistance to heat flow, and the better its insulating value. When the space between the panes of glass is filled with an inert gas (typically argon or krypton) the U-Factor is dramatically reduced.
As shown here, our windows with a low emissivity (or low-e) glass option and argon gas fill will out perform a standard clear unit by as much as 51% in the winter months.
